Director


Prof. Tim Fisher

Timothy S. Fisher (PhD 1998, Cornell) was born in Aurora, IL USA. 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.

Members


Majed Alrefae

Majed joined the group in Spring 2014 as a PhD student in Mechanical Engineering. He received the MS degree from KAUST and a bachelor’s degree from KFUPM, Saudi Arabia in 2013 and 2008, respectively. He worked as a project engineer from 2008 to 2011 at SABIC. His main research involves the study of physical/chemical processes for synthesis of carbon nanomaterials in plasma chemical vapor deposition systems aided by the use of laser/optical diagnostic techniques.

Aaditya Candadai

Aaditya joined the group as a MS student in Spring 2016. He is currently working on optimizing the roll-to-roll manufacturing of graphene on metal substrates using plasma CVD, as well as studying the oxidation protection of graphene on Copper using image processing techniques. He is also interested in studying the heat spreading properties of graphene films on copper. He was previously at BITS Pilani, India, where he completed his Bachelor’s degree in Mechanical Engineering. His undergraduate work was based on the performance analysis of a solar thermoelectric generator that employed spectrally selective absorber coatings.

Brian Fu 
Brian graduated with a BS in Mechanical Engineering from UCLA in 2016. He joined the graduate program in August 2016 and is working on rapid transient cooling technologies.  
Melissa Flores
Melissa started as a PhD student at UCLA in 2016. She received her B.S. from Cal State Northridge in 2014 in mechanical engineering and applied mathematics. Her work experience includes 2 years as an R&D software engineer at Northrop Grumman and 2.5 years as an aerothermal fluids engineer at Aerojet Rocketdyne.  Her research focus is on flash cooling of aerospace devices. 
Yijun Ge
Yijun joined the group in Fall 2015 as a PhD student in Mechanical Engineering. She received the MS degree from Purdue University and bachelor's degree from HUST, China. She is working on oxide interface thermal transport, using Density Functional Theory in combination with an atomistic Green's Function approach. She is also interested in thermal transport and electron-phonon coupling mechanisms in metals and 2D material interfaces.  
 
Ujash Shah
Ujash joined the group in Fall 2016 as a Direct PhD student. He graduated with a Bachelors (Honors) degree in Mechanical Engineering from BITS-Pilani, India with a joint thesis in association with UBC, Canada. His undergraduate research involved experimental and computational studies on Fluidized Bed systems for both energy generation and chemical processes. His current research involves theoretical, computational and experimental studies for nano-confined fluids with the goal of development of small-scale nano-fliud devices and subsequent scale-up. He loves to hike and is a fan of strategic multiplayer e-sports.

Yuan Hu

Yuan finished his MS with Professor Fisher at Purdue (SJTU 3+2 program) and after two years at Eli Lilly as process engineer he returned in 2016 Spring to continue as a PhD student. Currently he works on experimental heat transfer, such as flash techniques (potentially for electronic cooling and desalination) and thermal property measurements. He also works on electrochemical impedance spectroscopy (EIS) techniques for supercapacitors. He developed an low cost, efficient,cloud based EIS instrument with LabVIEW software and custom hardware that produce comparable accuracy compared to popular commercial instruments. He also once played varsity table tennis.

Yanguang Zhou

Yanguang received his PhD (2017) from RWTH-Aachen University (Germany). Before that, he finished his bachelors (2011) and masters (2014) studies at China University of Geoscience and Beihang University (China), respectively. His research interests are mainly in developing new computational frameworks for nanoscale heat transport considering high-order scattering and effects such as electron- and magnon-phonon, as well as nanostructuring to improve thermal and electrical transport properties. More details can be found on his Google scholar and researchgate pages. Apart from research, he is a crazy fan of basketball.

Arpan Kundu

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.
