(John) Alex Crosse is a Visiting Assistant Professor of Practice in Physics and Mathematics at NYU Shanghai. He received his Ph.D. from Imperial College in 2011 under the direction of Prof. Stefan Scheel (now at the University of Rostock, Germany) and subsequently worked as Postdoctoral Research Fellow at the Chinese University of Hong Kong in the group of Prof. Renbao Liu (2011-2013) and as a visiting scholar (2014) and then Postdoctoral Research Fellow (2014-2015) in the groups of Prof. Aaron Danner and Prof. Mankei Tsang (respectively) at the National University of Singapore. He joined NYU Shanghai in 2016, initially as a postdoc in the group of Prof. Pilkyung Moon and later as a visiting professor of Physics and Mathematics.

Dr. Crosse's research interests are in the control of quantum systems (atoms, electrons, photons) using novel materials (e.g. graphene, topological insulators). These topics lie at the interface of quantum optics, condensed matter theory and photonics. Previous work includes the effect of dispersive, absorbing media on the properties of atoms, high sideband generation and optical modulation in semiconductors, transport properties in strained graphene and photonic control using topological insulators. Current work involves the study of the magnetic band structure of layered 2D materials.
