Deep Punj

Postdoctoral Fellows


He joined the group in July 2015 as a postdoc after finishing his PhD in Feb 2015, from Institut Fresnel, Marseille, France. During his PhD, he worked to find enhanced fluorescence signals at physiological concentration using optical antennas at single-molecule level. He received his master degree in Photonics from Cochin University of Science and Technology, Kerala, India in 2011. His current research involves the spatial and temporal control of the localized excitation source, through the combination of nanofabrication with different spectroscopies.
