Prof_Shakouri_pic2.jpg Ali Shakouri is Mary Jo and Robert L. Kirk Director of the Birck Nanotechnology Center and Professor of Electrical and Computer Engineering at Purdue University. He received his engineering degree from Telecom Paris in 1990 and Ph.D. from the California Institute of Technology in 1995. His current research is on nanoscale heat and current transport in semiconductor devices, high resolution thermal imaging, micro refrigerators on a chip, and waste heat recovery. He is also working on a new sustainability curriculum in collaboration with colleagues in engineering and social sciences. He received the Packard Fellowship in Science and Engineering in 1999, the NSF Career award in 2000, and the Semitherm THERMI award in 2014.

kaz-yazawa_pic.jpg Kazuaki Yazawa is a Research Associate Professor of Birck Nanotechnology Center at Purdue University and an Adjunct Professor of Electrical Engineering at University of California Santa Cruz. He holds a Ph.D. degree from Toyama Prefectural University in Japan. He is a thermal and thermo-energy engineer worked as a Distinguished Engineer for Sony Corporation experienced nearly 30 years on electronics products. The area of interest includes the thermoelectric power generation and the thermoelectric refrigeration in applications ranging from a microelectronics chip all the way up to the scale of various buildings and power grids. Recent work on the use of thermoelectric co-generation with solar energy extensively explores a new era of the renewable energy technologies. His recent work also includes time domain analysis on the optimization of tri-generation (electricity, heating, and refrigeration) for maximum use of intermittent natural energy sources and unsteady energy loads, as well as on the quantum scale non-equilibrium heat transfer for energy applications. Dr. Yazawa is actively serving as a member of numerous international societies and conference committees in heat transfer, thermal management, and electronics packaging across Japan, the United States, and Europe.

Post Doctoral

bjorn-vermeersch.jpg Bjorn Vermeersch received his B.S., M.S. and Ph.D. degrees in Electronic Engineering from Ghent University, Belgium, in 2003, 2005 and 2009 respectively. He is currently associated with UCSC’s Quantum Electronics Group as a postdoc researcher, with his work focusing on the ultrafast characterization of thermoelectric and microelectronic devices. Femtosecond pump-probe laser techniques are employed to resolve high-speed thermal transients and carrier dynamics. During an earlier short-term scholarship at the Group in 2008, Bjorn developed a novel heterodyne lock-in scheme for high-resolution AC thermoreflectance imaging.

amir-ziabari.jpg Amirkoushyar Ziabari is a PhD student at QUEST group at Purdue University. Amir’s work under supervision of porfessor Shakouri involves a variety of projects, both on the experimental and the theoretical side. On the experimental side Amir is working on linear and nonlinear thermoelectric effects. He is using thermoreflectance thermal imaging to characterize thermoelectric materials and modules. He is validating his experimental results with analytical and FEM modeling. Amir has developed a hybrid numerical-analytical model to extract nonlinear (current-dependent) Peltier coefficient in lightly doped semiconductors. Amir’s theoretical works mostly involve simulation and analytical modeling. He is working on development of an analytical model to address thermo-mechanical stress in thermoelectric modules under low and high temperature loads. He is also using FEM (ANSYS) confirm this analytical model. Additionally, Amir is employing image processing algorithms to solve inverse heat problem in 3DICs to extract the location and amount of heat in different layers of the 3DICs. This is a continuation on his M.Sc work on developing an ultrafast and accurate technique (Power Blurring) to calculate temperature profile of IC/3DICs from their power dissipation map. Amir has received his two masters degrees from University of California Santa Cruz, and Sharif University, Tehran, Iran. He received his B.Sc in Electrical Engineering from Amirkabir University(Tehran Polytechnic),Tehran, Iran.
