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.

Graduate Students


Amirkoushyar Ziabari is a PhD student at QUEST group at Purdue University. His thesis is on "Imaging and Finite Element Approaches for Multiscale Electrothermal Phenomena". Currently, he is mainly focused on study of nanoscale heat transport and sub-diffraction imaging of thermal effects in semiconductor devices. He is using image processing techniques to extract 2D temperature distribusion of sub-diffraction devices from thermoreflectance thermal imaging microscopy and study heat transport at nanoscale. He has also studied the linear and non-liner thermoelectric effects in semiconductors both experimentally and theoretically. Thermal stress analysis in high temperature thermoelectrics and their reliability study are other main projects he was involved in.

Amirkoushyar received his B.Sc and M.Sc in Electrical Engineering from AmirKabir University (Tehran Polytechnic), Sharif University of Technology, Tehran, Iran, and University of California Santa Cruz (UCSC), respectively. During his masters study at UCSC, he developed a self-consistent and fast transient thermal modeling technique (Adaptive Power Blurring) for VLSI ICs and 3D ICs in packages.
