  • Stefano Martiniani

    Assistant Professor of Physics, Chemistry and Mathematics

    New York University

    Stefano Martiniani is an Assistant Professor of Physics, Chemistry and Mathematics at New York University. He holds a Ph.D. in Chemistry and an M.Phil in Scientific Computing from the University of Cambridge, and a B.Sc. in Chemistry from Imperial College London. Dr. Martiniani’s research program revolves around the statistical physics of disordered and complex systems, focusing on the development of novel theoretical and computational frameworks to address problems spanning (i) the fundamental statistical physics of nonequilibrium systems, such as amorphous and active matter systems; (ii) the development and mathematical analysis of cortical circuit models; (iii) the integration of machine learning and sampling methodologies for molecular/material design and discovery. He has pioneered the development of techniques that enable the accurate determination of the volume of high-dimensional basins of attraction, which has led to the elucidation of their puzzling geometric structure and to the first direct test of the Edwards conjecture. Prior to joining NYU, Dr. Martiniani was an Assistant Professor of Chemical Engineering and Materials Science at the University of Minnesota - Twin Cities. Currently, he holds a Simons Foundation Faculty Fellowship, and previous awards include the Gates Cambridge Scholarship, St. John’s College Benefactors’ Scholarship and an Outstanding Ph.D. Thesis Award from the University of Cambridge.

  • Eric G. Fuemmeler

    Research Associate, Aerospace Engineering and Mechanics

    University of Minnesota

    Eric is responsible for designing ColabFit's database and expanding the functionality of the colabfit-tool API. He received his Ph.D. in theoretical/computational chemistry from Cornell University, where he worked with Dr. Nandini Ananth to investigate the electronic structure of nonadiabatic systems with applications to next-generation solar cells and catalysis. As a postdoctoral fellow, he worked with Dr. Robert DiStasio Jr. at Cornell to develop intuitive orbital localization schemes applied to occupied and virtual spaces, and with Dr. Bradley Erickson at Mayo Clinic to develop AI tools for the early detection of pancreatic cancer.

  • Amit Gupta

    Research Associate, Aerospace Engineering and Mechanics

    University of Minnesota

    Amit is a post-doctoral associate working on using the ColabFit framework for developing machine-learned force fields for 2D materials. He has obtained his PhD in Physical Chemistry from Indian Institute of Science, where he explored the dynamics of 2D MoS2 in various solvent media, and tried to reconcile experimental spectroscopic measurements with molecular dynamics simulations. Following his PhD, he worked as a post-doc at Tata Institute of Fundamental Research for developing datasets and methods in learning ground state and excited state molecular properties.

  • Josh Vita

    Postdoctoral Researcher

    Lawrence Livermore National Laboratory

    Josh Vita is currently a postdoc at Lawrence Livermore National Laboratory working on uncertainty quantification for interatomic potentials. Josh obtained a Ph.D. in materials science and engineering from the University of Illinois Urbana Champaign (UIUC) in 2023, where his work focused on the development of efficient, interpretable models for describing atomic interactions, and the design of algorithms and databases for fitting those models. He graduated with bachelors degrees in materials science and mathematics from the University of Arizona in 2017 and interned at Sandia National Laboratories (2016) developing image analysis software.

  • Mingjian Wen

    Assistant Professor in Chemical and Biomolecular Engineering

    University of Houston

    Mingjian was a Ph.D. student working with Prof. Tadmor on developing KIM-based fitting framework for traditional "physics-based" and machine learning interatomic models. He is currently an Assistant Professor in Chemical and Biomolecular Engineering at the University of Houston (UH).
