Bio
Dr. Neogi explores light-emitting semiconductor materials a few nanometers in size. He uses ultra-short laser light pulses to take snapshots of these quantum dots for optoelectronic and biotechnological applications, such as light-emitting devices for traffic lights, bio-sensors and cancer detection.
