After earning his PhD in Physics at the Massachusetts Institute of Technology (2008), he spent 3 years as a postdoctoral fellow at Harvard University. In 2011 he joined the faculty of Ohio State University as an Assistant Professor, before moving to NBIA in the fall of 2012. Mark has worked on a wide range of topics, including electron-nuclear spin dynamics in semiconductor quantum dots, electron transport and photothermal effects in graphene, spin-orbit coupling in carbon nanotubes, and topological phenomena in dissipative and periodically-driven systems.
