Pauli Kehayias

Pauli Kehayias

2019 Truman Fellow

Pauli received his BS in engineering physics from Tufts University and PhD in experimental AMO physics from UC Berkeley in 2015. Most recently, he has been a postdoc at the Harvard-Smithsonian Center for Astrophysics, where he has been working on magnetic sensing applications in geology, biology, and NMR using nitrogen-vacancy (NV) color centers in diamond. At Sandia, Pauli will work on demonstrating novel applications of NV centers as a high-resolution sensor for imaging microwave fields emitted by "live" electronics. His research will enhance Sandia's capabilities in microelectronics and microsystems and in fundamental materials science and nanotechnology. His mentor will be Peter Schwindt and his manager Shanalyn Kemme, in AO Sensing and EC Engineering (5228).

Thomas O'Connor

Thomas O'Connor

2019 Truman Fellow

Thomas received his BS in physics from RPI and his PhD in physics from Johns Hopkins University in 2018. Thomas' research interest has been the application of molecular-dynamics modeling to the prediction of bulk properties of polymer materials, where he distinguished himself by solving a decades-old problem regarding the strength of polyethylene. He proposes to apply his molecular modeling techniques to better understand how polymer liquids flow when they are rapidly stretched during industrial processing. These studies will guide his efforts to develop new hydrodynamic models for polymer flow during additive manufacturing. His research will help to understand and predict the behavior of specific polymer chemistries used in additive manufacturing, thus allowing the quicker and more effective identification and adoption of new material systems. Thomas' mentors will be Gary Grest and Mark Stevens and his manager will be Ryan Wixom, in Nanostructure Physics (1881).
