Dr. Fedin is an Assistant Professor in the Department of Chemistry and Biochemistry. He has 10 years of experience in the synthesis of colloidal semiconductor nanocrystals of various shapes (dots, platelets, rings) and compositions. He characterizes his materials with microscopy (HRTEM), spectroscopy, and electrochemistry. Dr. Fedin is motivated to produce a stable, durable, strong, and fast near-IR emitter.

Research Interests
The research in the Fedin lab encompasses programmable colloidal nanoscale materials for single-photon sources, imaging, energy applications, and biological applications. In the first direction, my group explores the chemistry at the interface of “traditional” colloidal nanomaterials and the emerging field of layered two-dimensional materials to produce programmable functional heterostructures. In the second direction, we synthesize stable, highly luminescent heterostructures of near-IR semiconductors as potential on-demand quantum emitters.
