Pushing the Limits of 2D Janus Layers

Abstract:Named after the two faced Roman God Janus, 2D Janus layers contain two different atomic types on its top and bottom faces. Previous theoretical studies have shown that broken mirror symmetry together with large change transfer across the top and bottom face opens up completely new quantum properties including Rashba effect, colossal Janus field, dipolar excitons, and Skyrmion formation. Despite the theoretical advances in the field, experimental results are still limited due to limitations in high quality 2D Janus layer synthesis. In this talk, I will introduce recent discoveries made at Arizona State University towards different types of Janus layers. The growth process relies on Plasma enhanced low pressure chemical vapor deposition (PE-LPCVD). With this all room temperature technique, our team can synthesize different Janus layers as well as their vertical / lateral heterojunctions, and Janus nanoscrolls. Further studies from our team will introduce on-demand fabrication of 2D Janus layers with unique in-situ growth capabilities that allows us to collect spectroscopy data during the course of Janus material growth. Results are presented along with microscopy, spectroscopy, high – pressure studies, and electronic transport datasets for complete understanding of these systems.

Towards Modeling Antibody–Virus Coevolution and Escape: Integrating Evolutionary Modeling, Molecular Dynamics Simulations, and Interpretable Machine Learning

In the Rationally Designed Immunotherapeutics and Interfaces (RDI) Lab, we integrate computational modeling, immuno-engineering, molecular biophysics, and machine learning to understand—and ultimately control—how immune systems respond to rapidly evolving viral pathogens. A key challenge in designing vaccines against such pathogens is engineering immunogens that elicit broadly neutralizing antibodies (bnAbs), which target conserved regions of viral surface proteins and thereby bind diverse viral variants. Yet, even the most potent bnAbs isolated from infected individuals to date have proven susceptible to escape by viral mutations that weaken or abolish bnAb binding. Notably, neutralization datasets frequently reveal escape mutations at sites distal to the antibody-bound epitope, suggesting that allosteric and epistatic effects play a key role in modulating binding. In most cases, the mechanistic basis by which these distal mutations confer escape remains poorly understood, limiting our ability to design vaccine immunogens or antibody-based therapeutics that are resistant to escape mutations.

To address this gap, this talk will highlight our use of evolutionary frameworks to model B cell affinity maturation against static sequences of HIV-1–derived immunogens administered via time-varying immunization protocols. This approach enables us to understand how different vaccine strategies shape antibody lineages and guide them toward broadly neutralizing responses. In parallel, coupling these models of immune evolution with dynamic viral fitness landscapes enables identification of escape pathways that may be exploited in vivo, thus informing the iterative design of immunogens and immunization strategies capable of eliciting fully escape-resistant bnAbs. To further resolve the mechanistic basis of escape, this talk will also describe our use of atomistic molecular dynamics simulations and interpretable machine learning to characterize how distal mutations propagate dynamical changes through the structure of HIV-1’s Envelope (Env) spike protein to abrogate antibody binding and neutralization. Complementing these structural insights, we have developed an interpretable protein language model framework trained on HIV-1 sequence data and bnAb neutralization profiles. This framework identifies context-dependent mutational effects that rewire long-range residue-level communication networks governing antibody sensitivity. Together, our work provides a mechanistic foundation for designing next-generation immunogens against highly mutable pathogens like HIV-1, as well as antibody-based therapeutics that are more robust to rapid viral evolution.

Toward efficient inference in complex systems

Abstract: I will present a line of work on efficient inference in complex systems, spanning both the foundations of machine learning and applications to brain imaging data. The talk is organized around two complementary directions.

In the first part, I will study modern algorithms for sampling, estimating normalizing constants, and estimating likelihoods. These methods often rely on a probability path that connects a complex target distribution to a simple base distribution, such as a Gaussian. I will highlight fundamental limitations of classical approaches, and show how path-guided algorithms can substantially improve efficiency. I will also discuss principled strategies for designing these probability paths, explaining when and why such methods succeed.

In the second part, I will turn to machine learning algorithms that are applied in neuroscience, presenting recent results on learning representations and discovering causal structure from brain imaging data. This line of work is a step toward using machine learning to obtain new scientific insights.

I will conclude with open questions in the field and future directions at the intersection of generative modeling, sampling, and their scientific applications.

Title: Bridging Scales: High-Fidelity Characterization and Modeling to Deploy Sustainable Working Fluids

Abstract: Climate change is driving the decarbonization of energy systems, where reducing direct and indirect CO₂ emissions is critical to lowering the environmental impact of cooling, heating, and power conversion technologies. Approximately 40% of U.S. energy is consumed by buildings, and interest in decarbonizing commercial cooling and industrial processes through heat pumps and waste heat recovery is rapidly increasing. At the same time, the environmental impact of the working fluids themselves cannot be overlooked, and evolving regulations phasing out working fluids further complicate the development of sustainable thermal systems. This talk will address these themes in the context of two research efforts: High-temperature heat pumps and expansion work recovery in transcritical CO₂ refrigeration systems. In these efforts, experimental and numerical methods were employed across a range of fidelities, from empirical correlations to high-frequency pressure pulsation measurements. The challenges and opportunities associated with low-global-warming-potential working fluids will be discussed, along with examples of ongoing research, infrastructure development, and future directions.

Bio: Riley Barta has been an Assistant Professor of Mechanical Engineering at Purdue University’s Ray W. Herrick Laboratories since 2023. His research area is thermal systems technology, with a focus on the characterization and implementation of environmentally friendly working fluids and the development of equipment to utilize them in vapor compression systems, waste heat utilization, refrigerant property characterization, data center and electronics cooling as well as aircraft thermal management.

Additionally, he received the DKV (German Refrigeration Society) Young Talent Award for his Ph.D. Dissertation on efficiency increasing measures for transcritical CO2 refrigeration systems. He holds a bachelor’s degree in mechanical engineering and a Ph.D. in mechanical engineering from Purdue University.

Reinforcement Learning for Digital Health Interventions in the Dyadic Setting
2026-04-10 12:00 - 13:00 | 1163 Mechanical Engineering, 1513 Engineering Dr., Madison, WI, 53706, United States
UW-ISyE looks forward to welcoming Susan Murphy Professor of Statistics and of Computer Science and Associate Faculty at the Kempner Institute, Harvard University.

We present our ongoing work on the development of an online reinforcement learning (RL) algorithm for dyadic digital intervention settings in which the task for the RL algorithm is to assist the target person with a difficult illness be adherent to behavioral activities. To achieve this goal the RL algorithm will not only deliver digital interventions to the target person but also deliver interventions to assist the carepartner to manage caregiving burden and help the two individuals improve their relationship. That is, different RL components target different elements of the dyad. The RL algorithm is a multi-agent RL algorithm in which the 3 agents make decisions on the 3 elements of the dyad. We incorporate domain knowledge in the form of approximal causal directed acyclic graphs to speed up online learning in this sparse data setting. This work is motivated by our development of the ADAPTS-HCT multi-agent RL algorithm, designed to improve medication adherence by young adults who have undergone a blood and bone marrow transplant. The RL algorithm will be deployed in summer 2026.

Title: Explainable deep learning and foundation models: control and scientific discovery

Abstract: In this seminar we discuss a unified framework that combines explainable deep learning, deep reinforcement learning (DRL) and foundation models to advance both understanding and control of turbulence, with direct implications for accelerated design and discovery. First, we will show how explainable deep learning techniques can be used to identify the flow features that are truly responsible for key turbulent processes in wall-bounded flows. By systematically interrogating trained neural networks, we uncover the most influential coherent structures driving momentum transport and drag. Our results reveal that classically studied structures (while important) provide only a partial and sometimes misleading perspective, motivating a more data-driven and physics-aware view of turbulence organization. Building on these insights, we will demonstrate how deep reinforcement learning can be used to actively control turbulent flows by targeting the dynamically relevant structures identified through explainability. This approach achieves over 30% drag reduction in canonical wall-bounded turbulence and extends naturally to more complex configurations, including turbulent wings, highlighting the scalability of learning-based control strategies. Finally, we will introduce a foundation-model-based framework for accelerated design, optimization and scientific discovery. By learning compact, interpretable latent representations of high-dimensional flow physics, these models (combined with agentic-AI systems) enable rapid exploration of design spaces, causal reasoning and closed-loop optimization, bridging the gap between expensive simulations, control and engineering decision making. Together, these results illustrate how explainable and agentic AI are becoming essential for turbulence physics, flow control and next-generation engineering design.

Learning to See, Adapt, and Forget: From Computational Imaging to TrustworthyMultimodal AI

Abstract: A central challenge in modern AI is that the world at test time does not match what was assumed at training time. Physical sensors operate under constraints, modalities go missing, data shift out of distribution, and models retain information they were never meant to keep. Building systems that remain robust and reliable under incomplete, shifted, or misaligned information is the organizing question of my research program.

In this talk, I will present our research spanning physically grounded inverse problems to large-scale trustworthy AI, showing how robust behavior across different applications can be achieved through principled, low-dimensional representations and adaptations. I will begin with computational imaging, where we seek robust recovery of multidimensional data from indirect or incomplete measurements. I will discuss domain expansion and wavefront sensing, showing how principled algorithmic innovations lead to robust models for challenging inverse problems. I will then discuss multimodal learning, where we seek robustness against missing and imbalanced modalities at train or test time via parameter-efficient adaptation, proxy token generation, and model merging across modalities. Finally, I will discuss targeted adversarial attacks and unlearning, where we seek to exploit model vulnerabilities or remove targeted information (e.g., identities, concepts, unsafe content) without affecting unrelated capabilities.

I will close with a discussion of ongoing work and open problems spanning robust multimodal AI at scale, continual learning with efficient unlearning, and AI-guided sensing for medical, agricultural, and scientific applications.

A Tale of Two Motilities

In the spirit of Bird, Stewart and Lightfoot, we have been studying an important problem in transport phenomena, the biological and bio-inspired motility of cells.

Motility is important for the functioning of the immune system, mostly because immune recognition requires molecular transfer by direct cell to cell contact. We have been studying a fascinating form of cell motility in which T-lymphocytes can migrate against the direction of flow, much like a salmon can swim upstream. Upstream migration is solely due to interactions between a specific lymphocyte receptor, LFA-1, and its natural ligand; no other receptor can support upstream migration. Our lab has found that many actively motile cells in the immune system have the ability to migrate upstream. Using CRISPR-Cas9 deletion, we have identified several molecules in cells that are critical for upstream migration; deletion using Cas9 reverses the direction of migration. We have also made the first traction maps of forces exerted by upstream migrating cells. We found that during upstream migration, cells maintain their “architecture,” with active forces in the front and rear, but the magnitude of the forces greatly increases, allowing cells to exert sufficient traction to overcome the applied hydrodynamic forces.

Our laboratory is also interested in making synthetic cells, or protocells, that can mimic the behavior of biological cells. In collaboration with Daeyeon Lee at Penn, we have been making inert capsules using microfluidic assembly that can display motility in solution. By attaching urease to the surface of a capsule, we can drive autonomous motion of the capsule in a field of urea. We find that asymmetry of the capsule, in geometry or chemistry, or both, greatly enhances capsule motion. In gradients of urea, our capsules display negative phoresis (move down the gradient). We have preliminary results for the urease-driven motion of Janus capsules, made by microfluidic assembly from mixtures of phase-separating polymers, as a function of the geometry of the capsules.

In the end, we draw analogies between our biological and bio-inspired motile systems, ultimately finding they have little in common.

Title: From Graduate Research to Global Impact: Building a CFD Company That Challenged Convention

Abstract: This seminar reflects on the journey from graduate student at the University of Wisconsin–Madison to co-founding a company built on the idea that even established engineering fields can be reimagined. I will share formative experiences from my time at UW–Madison, the early vision behind building a different kind of CFD company, and the challenges of pursuing an approach that did not always align with conventional thinking.

Along the way, I will highlight how computational fluid dynamics has grown from a specialized research tool into a technology with global impact across transportation, energy, and other critical industries. More importantly, I will reflect on the lessons learned: that meaningful innovation often requires patience, resilience, and the courage to trust fundamentals over trends.

For students and researchers, the message is simple: protect your curiosity, question assumptions, and be willing to take the long path. The most impactful ideas are not always the most popular at the start, `but they are the ones worth pursuing.

Bio: Dr. Kelly Senecal is a co-founder of Convergent Science, an industry-leading computational fluid dynamics software company. He is a visiting professor at the University of Oxford and a co-founder and director of the Computational Chemistry Consortium (C3).

Title: Material model discovery: from sparse regression to the language of material laws

Abstract: The lecture provides an overview of recent research by the speaker’s group and collaborators on the automated discovery of material models. This research advocates a paradigm shift: moving beyond the traditional approach of calibrating unknown parameters within a preselected material model, towards the new objective of model discovery.

Model discovery entails the simultaneous selection, generation, or encoding of the most suitable model to interpret experimental data, along with the calibration of its parameters. To this end, a variety of tools are employed—ranging from sparse regression to Bayesian learning, and from formal grammars to symbolic regression. While each tool has distinct features, they share the common aim of enforcing physics constraints and ensuring interpretability of the discovered models.

Initially developed to discover a specific model within a given category (e.g. hyperelasticity, viscoelasticity, or plasticity), the approach has more recently been extended to the general case of materials belonging to an unknown class of constitutive behavior. Additional aspects such as data type, specimen design, and experimental validation are also discussed

Interactomics-driven discovery and characterization of plant natural product biosynthetic pathways in yeast

Plants are a rich source of small-molecule drugs and drug leads. Traditional methods for sourcing valuable plant natural products (PNPs) from their native producers are often limited by cost and inefficiency. Leveraging recent advances in synthetic biology and plant multi-omics analysis, our work has demonstrated that yeast is a viable platform for elucidating and reconstructing complex PNP biosynthetic pathways. We have developed an interactomics-driven strategy to capture post-translational protein-protein interactions between plant enzymes to elucidate pathways. Combined with prevalent genomics and transcriptomics analyses, this integrated approach led to the discovery and characterization of multiple PNP pathways from non-model plants, highlighting the potential of synthetic biology to revolutionize PNP-based drug discovery and development

Title: Integrating Physical Intelligence with Artificial Intelligence: Autonomous Design and Manufacturing of Emerging Material Systemsids

Abstract: Achieving superior performance in future material systems hinges on optimizing the heterogeneity of materials and structures. However, the design and fabrication of such advanced systems present significant challenges, requiring the integration of knowledge across multiple domains—including materials science, manufacturing, structural mechanics, and design optimization. This talk introduces a paradigm shift toward unifying “physical intelligence” with artificial intelligence (AI) to realize “embodied intelligence” in material systems. By combining data-driven generative design with physics-based modeling and simulation, we enable seamless integration of predictive materials modeling, advanced manufacturing, and design optimization—accelerating the development and deployment of next-generation materials. We will present state-of-the-art design methodologies that leverage statistical inference and AI techniques for the design of nano- and microstructured materials and programmable metamaterials responsive to external stimuli, covering methods such as machine learning, mixed-variable Latent Variable Gaussian Process (LVGP) modeling, Bayesian optimization, differentiable simulation, topology optimization, and generative design. The talk will also highlight recent advances in digital twins for autonomous co-design and manufacturing, using additive manufacturing as an example to showcase how these tools are transforming the landscape of intelligent material systems.

Title: Moving in a crowd: Decoding solid-fluid phase transitions of cellular collectives

Abstract: The organizational unit of life is the single cell, and yet the functional unit of multicellular organisms is the tissue, which is inherently collective. This leads to a fundamental question: how do cells self-organize into coherent, coordinated collectives? Importantly, in in vitro systems where external organizing mechanisms (e.g. tissue-level morphogen gradients) are absent, individual cells spontaneously self-organize into multicellular functional units. Towards developing an understanding of cellular self-organization into coherent collectives, we focus on the dynamics and structure of the human airway epithelium. Under homeostatic conditions, human airway epithelium is differentiated, stable, and able to withstand insults including pollution, allergens, and pathogens. This epithelial collective is typically stationary but exhibits collective migration in a range of circumstances, including during differentiation, in response to a variety of pathological stimuli, and under disease states such as asthma and COPD. As airway basal cells differentiate and form a stable tissue, they transition from a collectively migratory, fluidized state to a stationary, solid-like state. The fluidized state is characterized by cell elongation and alignment into cooperative migratory flocks, but as the collective solidifies, cells adopt more regular, isotropic, and homogenous shapes, and motion slows. This stationary, differentiated cellular collective can in turn be triggered to undergo a seemingly reverse process, in which the collective fluidizes, and large-scale, coordinated motion emerges. We find that well-described biological mechanisms can only partially account for the collective dynamics in this system, and begin to develop biophysical frameworks of cellular solidification and fluidization, towards understanding emergent multicellular coordination.

Bio: Dr. Mitchel received an undergrad degree in mechanical engineering with a minor in bioengineering from MIT, followed by graduate training in biomedical engineering with a focus on nerve tissue regeneration at Brown University. She went on to study mechanobiology and epithelial biology at the Harvard School of Public Health, and now runs a research group and teaches at Wesleyan University. Prof. Mitchel’s scientific work integrates techniques from cell and tissue engineering, mechanobiology, and cell biology, to explore how biological information at the single-cell level combines with local physical forces to drive collective cellular migration in development, regeneration, and disease. Prof. Mitchel teaches courses on cell biology, bioengineering, and cell migration. Her work has been supported by the Parker B. Francis Foundation and by the NSF.

BME Seminar Series: Paul Ellison, PhD

Preclinical nuclear medicine and magnetic resonance imaging for theranostic radiopharmaceutical development

Paul Ellison, PhDAssistant Professor, Medical PhysicsSchool of Medicine and Public HealthUniversity of Wisconsin-Madison

Abstract:The development of radiopharmaceuticals for use in nuclear medicine for the diagnosis and treatment of disease is a highly interdisciplinary field that integrates elements of engineering, materials science, physics, chemistry, and biology. It requires the use of a wide variety of specialty equipment, like particle accelerators, automated radiochemical synthesizers, and imaging systems, such as positron emission tomography (SPECT) or single photon emission computed tomography (SPECT) that provide biochemical information-rich spatial images, which are often paired with a second modality, such as x-ray computed tomography (CT) or magnetic resonance imaging (MRI) to provide accurate anatomical references. In this presentation, Dr. Ellison will discuss recent efforts to develop novel theranostic small molecule radiopharmaceuticals for PET imaging and radiopharmaceutical therapy of glioblastoma through targeting system xC–, a cell surface antiporter that exchanges cystine and glutamate as a key part of the cellular antioxidant defense system. Using modern chemically versatile halodeborylation chemistries, Dr. Ellison’s laboratory has prepared homologously matched radiopharmaceuticals that emit a variety of medically useful radiations, including positrons (18F, 77Br) and photons (131I) for imaging and Auger electrons (77Br) and beta particles (131I) for therapy. Comparative biology studies of this family of compounds utilize the gamut of preclinical imaging technologies, including PET, SPECT, CT, and MRI.
