Micro/nanoscale phase-change physics
The liquid-vapor phase change is one of the most effective thermal transport mechanisms with significant potential for the next generation of energy transport and storage solutions. However, such phenomena include complex multiscale nucleation and transport processes, making it challenging to understand underlying physics and control the behaviors. We investigate the micro/nanoscale phenomena utilizing nanoengineered materials, intelligent vision, and state-of-the-art model/experimental approaches to bring breakthroughs in the area of thermal sciences. In particular, we are currently interested in the following topics:
Intelligent thermal management
Due to the rapid increase of the power density within semiconductors and electrical platforms, thermal design and management have become one of the core differentiators substantially affecting the performance and reliability of such platforms. In many state-of-the-art devices, the number, size, and power density of chips and batteries are rapidly changing, which brings another challenge in terms of thermal design and management. To overcome such challenges, we have been developing intelligent thermal design methodologies and thermal management solutions. In particular, we are interested in combining artificial neural network optimization, novel thermal materials, and additive manufacturing to develop advanced thermal management solutions effectively.

Renewable thermal energy solutions
In our energy grid system, over 60% of the total energy input is wasted as heat. In many industrial platforms, such as buildings, electric vehicles, data centers, nearly half of electricity consumption is utilized for heating or cooling. Considering the accelerated climate changes and following environmental regulations, developing renewable thermal solutions that convert heat into electricity more efficiently or provide heating/cooling without utilizing electricity is becoming crucial. To address such challenges, we are currently interested in following renewable thermal energy solutions.
