Haogang Cai

Postdoctoral Appointee

Biography

Postdoctoral Appointee (Supervisor, Dr. Daniel Lopez)

Haogang Cai received his Ph.D. degree in Mechanical Engineering from Columbia University in 2016. His thesis work was on nanofabricated single-molecule platforms for mechanobiology studies. After postdoctoral research in Biological Sciences at Columbia University, he joined the Center for Nanoscale Materials at Argonne National Laboratory as a postdoctoral appointee. In the Nanofabrication and Devices Group, his research is focused on metasurface-based planar optics for the visible light.
