Welcome to the Park Research Group at Harvard
The Park Group is affiliated with the Department of Chemistry and Chemical Biology, Department of Physics, and Quantum Science and Engineering Program at Harvard University. The Park Group is located at the Conant Laboratory, 12 Oxford Street, Cambridge, MA 02138 (direction).
The group focuses on fundamental studies of nanoscale electrical, optical, and plasmonic devices that operate based upon quantum mechanical principles, as well as the development of new nano- and microelectronic tools that can interface with living cells, cell networks, and organisms. The goal of our quantum optoelectronics effort is to develop solid-state photonic, optoelectronic, and plasmonic devices that work all the way down to the single quantum level, thus paving the way for all-optical computing and solid-state quantum information processing. Our nano-bio interfacing effort is geared toward developing new nanoscale tools for interrogating living cells and cell networks, focusing on illuminating the behavior of immune cells in health and disease and the inner workings of the brain. In our quantum sensing/control effort, we develop ultra-sensitive magnetic, electric, and temperature sensors based on diamond color centers and use them to address various problems spanning condensed matter physics, molecular structural determination, and biological sensing.
Group meeting: We hold weekly group meetings and sub-group meetings. The schedule can be found here.
Positions Open: Our group is always open to qualified students and postdoctoral fellows in all areas. The application for the postdoctoral position can be sent to our lab administrator.
