Dr. Pinaki Majumdar

Dr. Pinaki Majumdar is currently a Scientist at Harish Chandra Research Institute, Allahabad, India.Having done his PhD from IISc Bangalore, Pinaki is working at the Harish Chandra Research Institute on disordered and strongly correlated electron systems. Despite the relative scientific isolation, Pinaki's focus has shown that one can nevertheless make a significant impact in the field of research - an example of which would be his numerous publications in Nature, PRL, etc. Very recently he was awarded the Bhatnagar Award 2007 by the Govt. of India - the highest award recognizing contribution to a particular area of science. His works has conclusively settled the relation between disorder, spatial clustering, and insulator-metal transitions in the manganites, and demonstrate how one can `exploit' disorder for electronic phase control in this important material. He is currently studying the double perovskites, which promise high ferromagnetic Tc and use in spintronic devices, as well as diluted magnetic semiconductors. Overall, his attempt has been to build a controlled computational approach to the study of transport in inhomogeneous correlated electron systems, creating a bridge between the nanoscale physics and real devices.

Dr. Tushar Choudhary

Dr. Tushar Choudhary is a Senior Scientist with Conocophillips at Bartlesville Technology Center.

Dr. Tushar Choudhary is a leading expert in heavy petroleum hydroprocessing technology, which is an important step in the production of clean transportation fuels. His pioneering research has unraveled several key aspects of the complex chemistry of heavy petroleum fractions and thereby transformed the state of knowledge in this critical area. Heavy petroleum crude fractions are an order of magnitude more complex than lighter petroleum fractions such as diesel and gasoline. Due to the limited supply of high quality crudes, refineries are being pushed towards using increasing amounts of heavy petroleum fractions which unfortunately are very difficult to process. Optimized processing of heavy petroleum fractions has historically been extremely difficult due to absence of adequate fundamental understanding. Via his revolutionary work Tushar has developed a molecular level understanding about heavy petroleum fractions and has integrated this understanding in form of an accurate heavy oil hydroprocessing optimization model. This model is being used successfully at several commercial heavy oil hydroprocessing units.

Over the years Tushar's research has received considerable recognition. His papers have been recognized as highly cited/accessed and have been highlighted in major technical and trade publications (e.g. Science, Chemical Engineering News, World-wide Refining Digest Weekly) and he is often invited to give keynote lectures at major conferences. In 2008 he was selected as one of the nation's eighty two brightest engineers to participate in the National Academy of Engineering's, U.S. Frontiers of Engineering symposium and was also awarded with the highly regarded award given at ConocoPhillips- Technology Innovation award.

Dr. Tushar has received his PhD from Texas A&M University in Physical Chemistry and a Masters from Indian Institute of Technology, Bombay
