Professor Jason R. Green, Principal Investigator
Jason Green is an Associate Professor of Chemistry and Physics at the University of Massachusetts Boston. He received a B.S. from Case Western Reserve University (cum laude) and a Ph.D. from Purdue University, supported by a NASA Graduate Student Researchers Program Fellowship. After an NSF Postdoctoral Fellowship at the Universities of Chicago and Cambridge, he was a Postdoctoral Research Associate at Northwestern University. His research interests are at the intersection of statistical mechanics, nonlinear dynamics, and information theory and their application to complex systems in chemical physics.

Shiqi Chen, Postdoctoral Research Associate
Dr. Shiqi Chen joined the group in October 2024 as a postdoctoral research associate and has been working on Koopman eigenvalues and entropy production rates in stochastic non-equilibrium thermodynamics. He obtained his chemistry PhD at the University of Chicago in June 2024. From 2018 to 2024, he worked with Prof. Norbert F. Scherer and Prof. Andrew L. Ferguson on the development and application of data-driven methods to study non-equilibrium steady states in optical matter systems. Before that he completed his undergraduate studies in Peking University in Beijing, China.

Swetamber Das, Postdoctoral Research Associate
Starting Fall 2024: Assistant Professor, Department of Physics, SRM University (India)
Dr. Swetamber Das joined the group in April 2020 after two years as a visiting scientist at the Max Planck Institute for the Physics of Complex Systems (MPI-PKS) Dresden (Germany). He obtained his PhD in 2018 from the Indian Institute of Technology Madras, Chennai (India) working with Prof. Neelima M. Gupte on impurity dynamics, transport, and synchronization in nonlinear discrete-time systems. At MPI-PKS he worked on the origins of partial barriers to transport in volume-preserving systems with Prof. Arnd Bäcker and developed an interest in biophysics and investigated a kinetic model of a gene regulatory motif exhibiting the influence of protein resource sharing. His interests are in the field of nonlinear dynamics and chaos and his current research involves classical speed limits on the response of dynamical systems.

Aishani Ghosal, Postdoctoral Research Associate
Dr. Aishani Ghosal joined the group in January 2023 as a postdoctoral research associate and has been working on speed limits in stochastic thermodynamics. From 2020 to 2022, she worked on stochastic thermodynamics of partially observed systems in the group of Dr. Gili Bisker at Tel Aviv University, Israel. Before that she was a visiting scientist at S N Bose National Centre for Basic Sciences, Kolkata (India), after finishing my Integrated Ph.D. degree in 2019 on theoretical studies of the non-equilibrium statistical mechanics of colloidal and polymeric systems at the single molecule level at Indian Institute of Science, Bangalore (India) under the supervision of Prof. Binny J. Cherayil.

Erez Aghion, Postdoctoral Research Associate
Starting Fall 2024: Assistant Professor, Department of Physics, University of Louisiana
Dr. Aghion joined the group in March 2021 and is working on speed limits in stochastic thermodynamics. From 2019 to 2021, he worked as a visiting scientist at the Max Planck Institute (MPI-PKS) in Dresden, Germany in the group of Holger Kantz. There, he focused on methods for deciphering anomalous diffusion in empirical time series. He completed his PhD at Bar-Ilan University, Israel, in 2019 under the supervision of Prof. Eli Barkai. His PhD research was on the physical applications of infinite-density functions for anomalous diffusion and unconfined thermal systems out of equilibrium. His experience so far is in stochastic processes, including stochastic thermodynamics, modeling, simulations and analysis.

Walter Lai, Ph.D. Student (Computational Sciences)
Walter joined the group in January 2023 as a Ph.D. student in Computational Sciences. He previously has worked as a software developer for FDM Group in which he developed automated reporting programs for financial institutions. His current research focuses on predicting energy dissipation in systems far from equilibrium using large scale molecular dynamics simulations.

Brendan Lucas, Ph.D. Student (Computational Sciences)
Brendan joined the group in September 2023 as a Ph.D. student in Computational Sciences. He previously has worked as an undergraduate researcher at the University of Massachusetts Lowell. His current research focuses on thermodynamic speed limits and machine learning.

Sepideh Ein Moghassemi, Ph.D. student (Chemistry)
Sepideh began as a graduate student in the Physical Chemistry Ph.D. program in September 2022. She graduated with a Master’s degree in Physical Chemistry from the Iran University of science and technology. At IUST, she worked under Dr. Majid Hashemianzadeh and Dr. Sajad Ghareghani in the Application of regression methods, dynamic simulation, and classification methods for estimating solubility and predicting the partition coefficient of 200 medicines. During her master’s degree, she also collaborated on a project using the ANI-1 neural network to predict the potential energy surface of some medicines. Her Ph.D. research involves the application of machine learning techniques to optimize, and predict dynamic behaviors, and developing these techniques for the function of materials.

Mohamed Sahbani, Ph.D. Student (Physics)
Mohamed joined the group in September 2021 as a Ph.D. student in Physics. His current research focuses on a classical density matrix theory. Within that theory, he is constructing a Fisher information in the tangent space of deterministic systems that is analogous to the quantum Fisher information and applying it to low-dimensional regular and chaotic dynamical systems.

Tae Hyun Ueon, Ph.D. student (Chemistry)
Tae joined the group in September 2022 as a Ph.D. student on the Physical Chemistry track. He spent three years in Sydney University with a major in Neuroscience before transferring to UMass Boston in the Fall of 2018 with a major in Chemistry. He graduated with a Bachelor’s Degree in 2022 (summa cum laude). At UMass Boston, he worked on a project with Prof. Neil Reilly modeling the electronic spectrum of alpha-hydrofulvenyl radical in the framework of Franck-Condon-Herzberg-Teller theory. His research currently focuses on speed limits in stochastic thermodynamics.
