Giridhar Madras received his chemical engineering degree from Indian Institute of Technology at Madras in 1990. He obtained his Ph.D. degree in chemical engineering from Texas A&M University, USA, in 1994. Subsequently, he worked in the University of California at Davis, USA. He returned to India as an Assistant Professor of chemical engineering at the Indian Institute of Science, Bangalore in 1998. Since 2007, he has been a Full Professor at the Chemical Engineering Department. He is also an associate faculty in Solid State and Structural Chemistry and a participative faculty in the Interdisciplinary Center for Energy Research.

His research interests are in the area of reaction engineering applied to polymers, supercritical fluids, and catalysis. His research group focuses on reaction kinetics, as applied to various systems and processes. The research group’s approach is to develop several new materials that are used as catalysts for known reactions. He proposes new reaction pathways/ mechanisms providing the research community with a method to develop new materials with superior properties. In this regard, his research group has synthesized new materials that work as photocatalysts for the degradation of a wide variety of dyes and organics that are common pollutants in waste water. He has also developed new catalysts for the three way catalysis for the NO+CO reaction and CO and hydrocarbon oxidation and proposed new mechanisms governing these reactions. His work on polymer degradation wherein the polymers are converted to useful products such as the monomers or fuel oils has been well received. Prof. Giridhar Madras also collaborates extensively with colleagues in Indian Institute of Science. His collaboration has resulted in varied research in the interdisciplinary field of chemistry and materials. Specifically, his collaborations have resulted in the work on new biomaterials based on polymers for drug delivery and tissue engineering; development of new polymers as encapsulants for solar cells; preparation of novel polymers for membranes and electromagnetic shielding; catalysts for specific selective reactions and several other projects.

He has successfully executed various projects worth several crores from various governmental agencies such as DST, DBT etc. and numerous industries such as BHEL, FMC, GAIL etc. He has graduated 30 Ph.D students and 40 master's students. In recognition of his early work, he received the Scopus Young Scientist Award from Elsevier for being the most cited young author in engineering. Based on his overall work, he was awarded the Presidential Swarnajayanthi fellowship by the Department of Science and Technology, India, in 2006 and the S.S. Bhatnagar prize from CSIR, India in 2009 from the prime minister of India and the J.C. Bose National fellowship in 2014. These are the country’s highest awards given for scientists below the age of 40, 45 and 60, respectively. He has been elected fellow of all the science and engineering academies of India and was recently given the IISc excellence award in teaching and research. He has published more than 400 international journal articles, which have more than 11000 citations and is among the most cited engineering scientists in India. He is listed by Web of Science as among the top 1% of all scientists in the world. He is currently the associate editor of several journals with various publishers including RSC advances (RSC), Advanced powder technology (Elsevier), Bulletin of Material Science (Springer), Current Science (Indian Academy) and International journal of polymer science (Hindawi).

In addition to scientific research, he writes a popular blog and maintains a website that answers questions for prospective faculty who want to return to India. In his free time (which he has plenty), he reads, translates Sanskrit literature and writes on Hindu philosophy.

As covered in the press

His group in IISc works on reaction kinetics, the study of rates of chemical reactions in various systems and processes.  Reactions between chemical compounds are dependent on a variety of environmental factors as well as active participants of the reactions. This area of study involves varying some of these parameters while keeping others constant in order to gauge their influence on the speed of reactions. This is especially useful in trying to find the rates at which plastics degrade and how they can be made to degrade faster to save the environment.  “I primarily study reactions at normal pressures, at high pressures (supercritical fluids), at high temperatures (catalytic reactions for energy and environmental applications) and between large molecules (polymers),” he explains.

After graduating from Annamalai University with a Bachelor’s degree, he worked his way to a Masters from the Indian Institute of Technology, Madras. He then completed his PhD from Texas A & M University in the USA. He continued his post-doctoral research in the University of California, Davis.

His motivation to succeed stemmed from his childhood and rural background. “We were from a very poor family and we had to struggle a lot. Education was not an option for me, it was  a necessity,” narrates Prof. Giridhar. “ I wasn’t sure if I would eat tomorrow. Education was my only hope.”

Prof. Giridhar has worked on 24 projects during his tenure at the Indian Institute of Science.  One of his projects is on reactions between macromolecules. Reactions concerning macromolecules (long chain polymers/plastics) are extremely important to understand for application towards environmental safety. His group studies the degradation of plastics for reuse and recycling. “We have developed continuous distribution kinetic models to determine the rate parameters and the activation energies for polymer degradation from the time evolution of the molecular weight distributions,” he adds. “The future of the plastic industry depends on its ability to synthesize biodegradable polymers of the required strength and durability. We have developed new methods to synthesize these biodegradable polymers.”

Another of his projects includes catalytic reactions. Catalysts speed up reaction rates and also make some otherwise difficult reactions possible. “In this regard, we have synthesized new materials that work as catalysts for the degradation of a wide variety of dyes and organics that are common pollutants in waste water. We have also developed new catalysts that will significantly reduce air pollution,” says Prof. Madras.

To study reaction kinetics, his group uses analytical equipment such as spectrometers, gas chromatographs, scanning electron microscopes, and other  high-end, state-of-the-art physical and thermal characterization equipment . Understanding the properties of the reaction products also provides an insight into the chemical processes that take place.

Prof. Giridhar Madras remarks that he hasn’t taken a break for vacation for the past fifteen years. “I found my inspiration in my field and in research after I came back to India and started to work in IISc. I was introduced to people like Dr. C.N.R. Rao and my other colleagues here who have a tireless enthusiasm for their research. Their work attitude and ethic was infectious and inspiring. I am happy to have come back to India because India educated me. I was supported by government scholarships throughout and it is my duty to give back to my country now. I feel India is one of the best places in the world and I am very proud to be an Indian.” says Prof. Giridhar Madras.

Prof. Giridhar has several awards to his name. He is the recipient of the J.C. Bose award, the S.S. Bhatnagar Award as well as the Swarnajayanthi Fellowship Award, which are the country’s highest awards for science and engineering. Internationally, he has also been ranked as among the top 1% of all scientists in the world. “You don’t work for these awards. If you don’t get it, it does not make  much difference. The enjoyment is in the journey and not the destination. If you don’t enjoy the path you walk on, then you only think of the goal and maybe lose out on that as well,” adds Dr. Giridhar, “I deeply care for my students and junior colleagues, and if they do well, some of that happiness comes to me. That is my greatest award.

Prof. Giridhar has a reputation as a great teacher. “Research is exciting for me because of my students. If I am able inspire my students, then it is exciting,especially when my students have discovered something new. I believe that in science, we will always find something new. The results of most of our experiments are almost always surprising. Students motivate me to do well and if they benefit from my teaching, it is the best inspiration” he adds. He says, " I believe that, no matter what, you have to do your best. My grandfather used to say, 'It's no disgrace to be a sweeper. But it's a disgrace to be a sweeper and not sweep well. I believe that, if you do it well, you will enjoy any profession and, if you enjoy your profession, you will perform well. Be simple, sincere, straightforward and spiritual.He believes that if you listen to your inner calling and have passion for what you do, you will always find time to do that and be successful in that. 

In addition to scientific research, he also reads and translates Sanskrit literature, writes a popular blog, maintains a website that answers questions for prospective faculty who want to return to India.
