He joined UCLA's Department of Mechanical & Aerospace Engineering in 2017 after spending 15 years at Purdue’s School of Mechanical Engineering, and several years previously at Vanderbilt University. He is the founding Director of the Center for Integrated Thermal Management of Aerospace Vehicles, supported by the US Air Force Research Laboratory and leading industrial members: Boeing, Honeywell, Lockheed Martin, Northrop Grumman, and Rolls-Royce. He is an Adjunct Professor in the International Centre for Materials Science at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) and co-directs the Joint Centre on Nanomaterials for Clean Energy and Environmental Sensors. From 2009 to 2012, 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. In 2013 he became the James G. Dwyer Professor in Mechanical Engineering at Purdue, and in the same year he founded a start-up company to commercial inventions from his laboratory. 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 studies of nanoscale heat transfer, carbon nanomaterial synthesis, coupled electro-thermal effects in semiconductor and electron emission devices, energy conversion and storage materials and devices, microfluidic devices, biosensing, and related computational methods ranging from atomistic to continuum scales.

Arpan joined the group as a PhD student in Fall 2013. His overall interests involve studying different unexplored electrical, thermal and optical effects with applications in energy storage systems. Currently he is working on an experimental setup for testing different electrodes and electrolyte materials for thermocells and thermally chargeable supercapacitors with applications in waste heat recovery. In the past, he has worked on developing a theory of electroreflectance in metal electrodes in collaboration with experimentalists and have used it to study spatial degradation of supercapacitors during aging. Prior to joining the group, he received his Bachelor's and Master's degree in mechanical engineering from the Indian Institute of Technology Kharagpur, India.

Cheolwoong Lim

Cheolwoong is a co-advised PhD student working from the IUPUI campus in Indianapolis under Prof. Likun Zhu. His research involves electrode microstructure optimization for battery applications.

Antonio Esquivel Puentes

Antonio is a visiting MS from the Universidad Nacional de Colombia. His research focuses on the synthesis by MPCVD of diamond-like carbon (DLC) coatings on titanium alloy and stainless steel for applications in wear, corrosion, biomaterials, and nano-structured materials. Prior to joining the group he obtained his BS in Mechanical Engineering from the Universidad Nacional de Colombia. He has also worked to develop a coating of DLC to corrosion and wear resistance on Ni alloy at the National Institute for Space Research (Brazil).
