Dr. MishraBrajendra Mishra
Kenneth G. Merriam Professor of Mechanical Engineering
Director of Metal Processing Institute
Worcester Polytechnic Institute

An internationally known researcher and educator in metallurgical and materials science and engineering, Brajendra is currently engaged in work focused on environmental management through the development of chemically benign processes and the development of materials with enhanced properties. His research over the past 25 years has been supported by more than $40 million in sponsored awards from multiple federal agencies, national laboratories, and industry. He is the author of more than 600 publications, including more than 280 papers in peer-reviewed journals. He has also edited 18 books and written seven chapters on chemical processing and extractive metallurgy.

He served as a trustee of the American Institute of Mining, Metallurgical and Petroleum Engineers (AIME) from 2007 to 2012 and its president in 2011. He was president of TMS (the Minerals, Metals and Materials Society) in 2006. His scholarship and leadership has been honored with a number of awards, including Honorary Membership, the highest award bestowed by the Indian Institute of Metals; the Alexander Scott Distinguished Service Award from TMS; Honorary Professor of Kazakh National Technical University and the Presidential Citation from AIME.

Mei Yang
Worcester Polytechnic Institute

Mei joined WPI in June 2017 as Assistant Research Professor and Associate Technical Director of CHTE. She was most recently a senior research and development engineer at H.C. Starck. She earned her PhD in materials science and engineering at WPI. Her expertise is integrated materials and processes development for both metals and ceramics. By combining modeling and experimental investigation, processes can be optimized and controlled to improve the reliability of their properties. Her current research focus is advanced heat treatment processes.
