Rajadurai Chandrasekar is a Professor at the University of Hyderabad (UoH). At the UoH he explores the Interaction of Light with Organic Nano/Microsolids. His group made several original and outstanding scientific contributions toward Advanced Organic Photonic Materials and Technologies such as Organic waveguides (passive-type discovered in his lab), resonators, optical modulators, and chiral optical waveguides and resonators, and circuits. He initiated two new research fields namely, (i) Mechanophotonics - a domain that integrates mechanical micromanipulation of single crystal photonic modules towards circuits, and (ii) Crystal photonic foundry - a novel approach involving focused ion beam milling of organic single crystals to produce various organic single crystal photonic modules. He has published about 125 research papers and holds 4 international patents. He has been an elected Fellow of the Optical Society of India (2016), the Royal Society of Chemistry (2018), the Indian Academy of Sciences (2020), and the National Academy of Sciences (2023). He is an International Advisory Board Member of several prominent Materials Chemistry and Materials Science journals such as Journal of Materials Chemistry C, Materials Advances, Advanced Optical Materials, ACS Applied Engineering Materials, and Small.
