SUMMARY:BME Seminar Series: From Campus to Career: Maximizing Experiences for Industry Readiness
DESCRIPTION:Abstract: Universities are organized primarily by departments\, but industry is organized by function: research\, design\, regulatory\, quality assurance\, sales\, marketing. Having some knowledge of this structure ahead of time will help you select and approach classes in ways more likely to have you end up where you want to be.Fortunately\, the UW-Madison also has many opportunities that let you “try on” an industrial career ahead of time. These opportunities vary in duration from hours to months. As you start to invest in these channels\, you will be more likely to benefit from the serendipity that the breath of expertise present at UW-Madison naturally provides.This seminar will feature three individuals in a conversational format who will discuss how they used these channels to supplement their coursework and research to build industrial success. While all three of these individuals eventually earned PhDs\, the topics and approaches discussed are equally applicable to MS students. \n\n\n\nSpeakers (L to R):Professor Chris Brace\, PhD; UW BME Vice Chair; Co-founder\, NeuWave MedicalJustin Koepsel\, PhD\, MBA; UW BME MS’08\, PhD’12; Senior Director of Commercial Operations at Catalent BiologicsTom Lilieholm\, PhD’24; Co-founder and Director of Neuroimaging ImgGyd \n\n\n\n\n\n\n\nPrint PDF

SUMMARY:Mechanics Seminar: Tanmoy Chatterjee
DESCRIPTION:The Mechanics Seminar Series is a weekly seminar given by campus and visiting speakers on topics across the spectrum of mechanics research (solids\, fluids\, and dynamics). Tanmoy Chatterjee is the Lead Research Engineer in Aerodynamics at GE Research Inc.  \n\n\n\nPresentation Title: From Turbulence to Turbines: Exascale CFD in Wind Energy \n\n\n\nAbstract: Wind energy is rapidly expanding in scale\, with individual turbines now exceeding 100-meter blades and offshore farms stretching tens of kilometers. Yet\, predicting their performance and more critically reliability remains a grand challenge of fluid mechanics\, spanning phenomena from centimeter-scale blade boundary layers to kilometer-scale atmospheric flows. This talk explores how exascale computational fluid dynamics (CFD) is transforming our ability to model and design wind energy systems across these scales. I will discuss recent advances in high-fidelity\, turbulent fluid–structure interaction simulations\, and their integration with the Department of Energy’s ExaWind project. Specific examples will include simulations of coastal low-level jets (LLJs) driving wind farm variability\, and the development of data-driven dynamic stall models for next-generation turbine blades. Together\, these efforts highlight how exascale CFD is reshaping our understanding of turbulence\, turbines\, and wind farms — and accelerating innovation in the renewable energy industry. \n\n\n\nBio: Tanmoy Chatterjee is a Lead Research Engineer in Advanced Simulations and Methods at the GE Vernova Advanced Research Center. Prior to joining GE\, he was a postdoctoral researcher at Argonne National Laboratory\, where he developed exascale CFD models using spectral codes for internal combustion engine simulations. He earned his Ph.D. in Mechanical Engineering from Arizona State University\, focusing on turbulence–turbine interactions in large wind farms. \n\n\n\nAt GE Vernova\, Dr. Chatterjee has led the development of high-fidelity exascale CFD–FSI simulations of wind farms and turbine blade-level turbulence\, as well as data-driven reduced-order models for blade vibrations in the regimes of stall-induced and vortex-induced vibrations (SIV/VIV). He has also contributed to advanced controller strategies for mitigating turbine loads under unconventional wind conditions. In addition to his technical contributions\, Dr. Chatterjee has successfully led several GE-internal and government-funded research initiatives\, including projects supporting the DOE-WETO RAAW campaign in collaboration with national laboratories and academic partners.

SUMMARY:Strong duals for mixed integer programs.
DESCRIPTION:UW-ISyE looks forward to welcoming Dr. Santanu Dey\, Professor at  H. Milton Stewart School of Industrial and Systems Engineering at Georgia Institute of Technology.  \n\n\n\n\n\n\n\nWe develop two general-purpose strong dual formulations for binary MINLPs\, motivated by sensitivity analysis and distributed computation. For mixed binary quadratic programs (MBQPs)\, we show that the copositive dual of Burer’s completely positive reformulation has no duality gap when the feasible region is bounded or the objective is convex. Since the right-hand side of the original MBQP appears only in the dual’s objective\, this formulation enables sensitivity analysis. For nearly decomposable nonlinear mixed binary programs\, we propose a hierarchy of relaxations that preserve decomposability. The first level coincides with the classical Lagrangian relaxation\, while higher levels yield progressively tighter bounds\, culminating in a strong dual. We analyze the quality of these bounds for various types of MILPs. This is joint work with Diego Cifuentes and Jingye Xu. \n\n\n\n\n\nBio: Santanu S. Dey is an Anderson-Interface professor and director of doctorial recruiting and admissions in the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Institute of Technology. Dr. Dey’s research interests are in the area of non-convex optimization\, and in particular mixed integer linear and nonlinear programming. His research is partly motivated by applications of non-convex optimization problems arising in areas such as electrical power engineering\, process engineering\, civil engineering\, logistics\, and statistics. He currently serves on the editorial board of Mathematical Programming A\, Mathematics of Operations Research and SIAM Journal on Optimization. He has previously served as an area editor for Mathematical Programming C and associate editor of INFORMS Journal on Computing. He has won the INFORMS Nicholson student paper competition\, IBM Faculty Award\, the Class of 1969 Teaching Fellow at Georgia Tech\, the NSF CAREER award\, the INFORMS Energy Natural Resources and Environment best paper award\, and the INFORMS optimization society Balas Prize.

SUMMARY:ME 903 Graduate Seminar: Professor Suo Yang
DESCRIPTION:The ME 903: Graduate Student Lecture Series features campus and visiting speakers who present on a variety of research topics in the field of mechanical engineering. Professor Suo Yang is a professor at the University of Minnesota. \n\n\n\nPresentation title: Multi-Physics Modeling for Future Aerospace Propulsion and Energy \n\n\n\nAbstract: In the development of future aerospace propulsion and energy systems\, the pursuit of high efficiency\, high speed\, low emission\, and low noise is pushing the systems to operate at extreme conditions. These conditions and associated emerging technologies often introduce complicated multi-scale physics\, bringing new challenges to modeling and simulation in terms of both fidelity and computational cost. In this presentation\, I will mainly talk about two examples of such multi-physics modeling from our works: (1) Plasma assisted combustion (PAC) is a promising technology to enable ultra-fast ignition and stable combustion using low-reactivity fuels (e.g.\, ammonia for decarbonization\, and low-cetane sustainable/synthetic aviation fuels) or at extreme conditions (e.g.\, high-speed flows in scramjets for hypersonic propulsion). We developed a series of 0D-3D PAC models with unprecedented predictivity\, unraveled the mechanisms of simultaneous ignition acceleration and NOx emission reduction by non-equilibrium plasma in ammonia combustion\, and investigated the influence of discharge pulsing frequency\, plasma streamer evolution\, inter-electrode gap distance\, igniter placement\, and turbulence on ignition performance. (2) Advanced liquid-fueled rocket and gas-turbine jet engines (based on deflagration or detonation) operate at high pressures to achieve high efficiency and high energy density. At such conditions\, the supercritical liquid-like fuel often goes through transcritical multi-component phase transition upon mixing with the oxidizer stream or colliding with detonation/shock waves. We developed a series of computationally efficient and robust multiphase flow models based on the first-principled real-fluid vapor-liquid equilibrium (VLE) theory to predict high-pressure multi-component phase transition\, and investigated its interactions with mixing\, combustion\, detonation\, (hypersonic) shocks\, and expansion waves. \n\n\n\nBio: Dr. Suo Yang is an Associate Professor of Mechanical Engineering at the University of Minnesota. During 2017-2018\, He was a Postdoctoral Research Associate in Mechanical & Aerospace Engineering at Princeton University. Dr. Yang received his Ph.D. (2017) and M.S. (2014) degrees in Aerospace Engineering\, and another M.S. degree in Computational Science & Engineering (2015)\, all from the Georgia Institute of Technology. He received a B.S. degree in Mathematics & Applied Mathematics from Zhejiang University in 2011. Dr. Yang’s research focuses on the modeling and simulation of turbulent reacting & multiphase flows\, including combustion\, non-equilibrium plasma\, particulate & multiphase flows\, and hypersonics\, with applications in aerospace propulsion & energy systems. He is an awardee of the 2021 DARPA Young Faculty Award (YFA)\, 2022 ONR Young Investigator (YIP) Award\, 2023 DARPA Director’s Fellowship Award\, and 2024 AFOSR Young Investigator (YIP) Award. Dr. Yang has authored nearly 100 journal articles and refereed conference papers\, in which he received 5 Editor’s Pick or Featured Article awards from Physics of Fluids and Combustion and Flame. Dr. Yang is a Senior Member of AIAA and a member of 3 AIAA Technical Committees. He has served as a Technical Discipline Chair or Deputy Chair 5 times for AIAA SciTech Forums. He also actively serves as a reviewer for many top-tier journals for which he received 4 Outstanding Reviewer Awards.

SUMMARY:NEEP Seminar Series: David Andersson\, Los Alamos National Laboratory
DESCRIPTION:Thursday\, October 212:00 – 1:00pm106 Engineering Research BuildingPlease contact office@neep.wisc.edu for assistance with remote participation. \n\n\n\nOverview of the DOE NEAMS program and review of multi-scale simulations to inform nuclear fuel performance modelsThis presentation will first introduce the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program\, which develops predictive modeling and simulation tools to support the design\, development\, licensing\, and operation of nuclear reactors. NEAMS activities span Light Water Reactors (LWRs)\, new LWR concepts\, and next-generation systems such as High Temperature Gas Reactors\, Fluoride Salt-cooled Reactors\, Liquid Metal Fast Reactors\, Molten Salt Reactors\, and Micro-Reactors. Research is organized into five Technical Areas: Fuel Performance\, Thermal Fluids\, Reactor Physics\, Structural Materials & Chemistry\, and Multiphysics Applications. Selected accomplishments from each area will be highlighted. \n\n\n\nThe second part of the talk will focus on multi-scale simulations for nuclear fuel performance\, with examples for uranium oxide in LWRs and\, if time permits\, other fuel types. A key element is understanding the thermodynamic and kinetic properties of point defects\, which strongly influence creep\, fission gas release\, swelling\, densification\, and thermal conductivity. Density functional theory (DFT) enables prediction of defect properties and provides a foundation for mechanism-based\, engineering-scale fuel performance codes. \n\n\n\nCurrent applications of DFT to UO2 will be presented\, including methods that incorporate dispersion corrections\, spin–orbit interactions\, and noncollinear magnetism. A point defect model informed by DFT energies and vibrational entropies predicts defect concentrations in UO2±x\, validated against experimental data for deviation from stoichiometry and self-diffusion coefficients. The cluster dynamics code Centipede further connects defect behavior to in-reactor performance by modeling production\, interactions\, clustering\, and kinetics under irradiation\, with implications for fission gas behavior\, fuel fragmentation and creep. The importance of these properties in extending fuel burnup limits and the role of uncertainty quantification in achieving qualification will be discussed. Similar approaches for other nuclear fuels\, including UN\, TRISO\, and molten salts\, will also be briefly mentioned. \n\n\n\n\n\n\n\nDavid Andersson\, Los Alamos National LaboratoryDavid Andersson is the National Technical Director (NTD) of the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program and the Deputy Group Leader of MST-8: Materials Science in Radiation and Dynamics Extremes.
