Georgios is a Data Scientist at Tufts University. As part of CHREST, he is primarily focusing on introducing uncertainty quantification to machine learning and building surrogate models for large scale simulations. Georgios earned his PhD from the School of Aeronautics and Astronautics at Purdue University. He has a Master's degree from Purdue University and an undergraduate degree in Mechanical Engineering from the National Technical University of Athens (NTUA). His doctoral research included the development of a crowd-based prototype to predict future project failures using machine learning and human analytics, he also investigated whether targeted feedback helps in preventing such failures. He has previously worked with jet engines, rocket propulsion systems, and on an experiment that flew on Blue Origin's New Shepard rocket to space.

Joseph Pusztay

Joe is a post doctoral associate in the Research Engineering Laboratory for Advanced Computational Science (RELACS). He graduated with a PhD in Computer Science and Engineering from the University at Buffalo in 2022. In his graduate work, Joe focused on the conservative simulation of kinetic plasmas with particle-in-cell discretizations leveraging a variety of tools to construct a framework within the Portable Extensible Toolkit for Scientific Computing (PETSc). A current research focus is added support for the scalable particle manager within PETSc and conservative transitions between particle and field representations, in addition to conservative particle basis collision operators for plasma simulation, and PETSc support for Lattice QCD experimentation.
