Director


Prof. Tim Fisher

Timothy S. Fisher (PhD in Mechanical Engineering, 1998, Cornell) was born in Aurora, IL. He joined the Purdue’s School of Mechanical Engineering and Birck Nanotechnology Center in 2002 after several years at Vanderbilt University. In 2013 Purdue named him the James G. Dwyer Professor in Mechanical Engineering. He is Director of the Center for Integrated Thermal Management of Aerospace Vehicles (CITMAV), funded by the Air Force Research Laboratory and key industrial partners. He is also an Adjunct Professor in the International Centre for Materials Science at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) and co-directs the JNCASR-Purdue Joint Networked Centre on Nanomaterials for Energy. From 2009 to 2011, he served as a Research Scientist at the Air Force Research Laboratory’s newly formed Thermal Sciences and Materials Branch of the Materials and Manufacturing Directorate. Prior to his graduate studies, he was employed from 1991 to 1993 as a design engineer in Motorola's Automotive and Industrial Electronics Group. His research has included efforts in simulation and measurement of nanoscale heat transfer, coupled electro-thermal effects in semiconductor and electron emission devices, nanoscale direct energy conversion, molecular electronics, microfluidic devices, biosensing, hydrogen storage, and related computational methods ranging from atomistic to continuum scales.
