Executive Summary
Dr. Debdas Ray was received his PhD degree in 2008 from the Indian Institute of Technology Kanpur, India. His doctoral research was conducted under the supervision of Prof. Dr. Parimal K Bharadwaj, and focused on designing various supramolecular receptors for sensing and nonlinear optical studies. He then carried out first postdoctoral research in Prof. Dario M. Bassani’s Group at University of Bordeaux1 (2009-2011), where he focused on the synthesis of fullerene (C60) and anthracene monolayers on silicon surfaces as well as various fullerene derivatives having hydrogen-bonding recognition unit for organic electronics. He did his second postdoctoral research in Prof. Ivan Aprahamian’s group (2011-2012) at Dartmouth College, USA, where he focused on hydrazine-based rotary switches for coordination-coupled proton relay mimicking proton translocation in biological systems. His 3rd postdoctoral research was carried out in Prof. Takashi Nakanishi’s group (2012-2013) at National Institute for Materials Science (NIMS), Japan, where he focused on “solvent-free” liquid organometallic complexes for optoelectronic applications.
