Postdocs

Hyeongyun Cha
Hyeongyun joined the DRL in April 2020 as a Posdoctoral Associate after receiving his Ph.D. in Mechanical Engineering from the University of Illinois at Urbana-Champaign. His doctoral research focused on condensation-driven solid-liquid interfacial phenomena and phase change heat transfer. At the DRL, he is currently working on understanding and optimizing boiling heat transfer using machine learning-based design approach.
Shuai Gong
Shuai joined the DRL in November 2017 after two years’ postdoctoral research at Shanghai Jiao Tong University (SJTU), where he received his Ph.D. in Engineering Thermophysics in June 2015. Shuai’s doctoral and postdoctoral research at SJTU focused on direct numerical simulations of boiling heat transfer using mesoscale lattice Boltzmann method (LBM). At the DRL, Shuai is involved in modeling and experiments of micro/nano-scale phase change heat transfer including boiling and condensation.
Gustav Graeber
Gustav joined the DRL in March 2021 as a postdoctoral fellow on a Postdoc Mobility Grant by the Swiss National Science Foundation. After studying mechanical engineering at TU Berlin (Germany), KTH Stockholm (Sweden), and RWTH Aachen (Germany), he graduated as a PhD from ETH Zurich (Switzerland). His doctoral research focused on freezing physics and derived surface nano-engineering for spontaneous deicing. After his PhD, Gustav joined the Swiss Federal Laboratories for Materials Science and Technology (Empa) as a postdoc to study wetting and phase change in electrochemical systems. At the DRL, Gustav investigates adsorption on tailored nanostructures and the rational design of hydrogels for atmospheric water harvesting.
Ryuichi Iwata
Ryuichi joined DRL in November 2017 as a visiting scholar. He received his Ph.D. degree in Mechanical Engineering from Osaka University in 2010. His Ph.D. research involved numerical simulations of bubble-particle interactions in liquid. He is interested in interfacial transport, surface engineering and energy systems. His current research is focused on micro/nanoscale transport phenomena in electrochemical systems.
Xiangyu Li
Xiangyu joined the DRL in June 2019 after graduating as a PhD from Purdue University. His doctoral research focused on nanoscale heat transfer in nanocomposites, thermal interfaces and radiative cooling. At the DRL, he is involved in the design and optimization of heat exchangers for high temperature and high pressure applications.
Wei Mengyao
Mengyao obtained her B.Eng. degree in Materials Science and Engineering from Nanyang Technological University in 2013. Her current research focuses on thermal management for integrated electronic systems utilizing advanced vapor chambers.
