The research of Thomas has been focused on photoresponsive nanomaterials and his work is reported to have assisted in widening the understanding about their applications.[8] He also worked on self-organization of molecules on surfaces and has developed methodologies for modulating molecular organization through the introduction of functional groups.[9] Thus, he developed a number of near-infrared absorbing sensitizers which are relevant in biological imaging and optical data storage applications. He holds an international patent for one the processes he has developed viz. Squaraine based dyes and process for preparation thereof.[10] His research has been documented by way of chapters in three books authored/edited by others and several peer-reviewed articles;[11] the online article repository of the Indian Academy of Sciences has listed 54 of them.[12] He sits on the advisory board of the Centre for Nano and Soft Matter Sciences of the Department of Science and Technology[13] and is the vice-president of the Asian and Oceanian Photochemistry Association.[14] He has also delivered several keynote addresses and plenary lectures including the Inter Academy Seoul Science Forum held in Seoul on 3 November 2016[15] and the Nano Biotek 2016 held at New Delhi on 24 November 2016.[16]
Awards and honors
Thomas received the Bronze Medal of the Chemical Research Society of India in 2004[17] and the MRSI Medal of the Material Research Society of India in 2005; MRSI would honor him again in 2015 with the MRSI-ICSC Super Conductivity and Materials Science Prize.[18] The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards, in 2006.[19] He was elected as a fellow by the Indian Academy of Sciences in 2008[4] and he became a fellow of the Indian National Science Academy in 2015.[3]
