Electrochemical Energy and Interfaces Laboratory
We study fundamental mechanisms and develop functional materials for electrochemical and bioelectrochemical energy storage and conversion. We investigate electrochemical interfaces including battery interfacial chemistry, electrocatalysis, and bioelectrochemical interfaces by employing spectroscopic and microscopic techniques coupled with in situ & ex situ electrochemical characterizations on model material systems. Applying insights gained from these mechanistic studies, we seek to develop material design principles for high-energy, efficient and long-lasting energy storage and conversion technologies for a sustainable energy future.

Nano Energy Research Laboratory
The Nano Energy Research Laboratory (NERL) is devoted to fundamentally understand energy and mass transport phenomena at the micro/nanoscale for advanced energy conversion and biomedical applications. Current research activities in the laboratory are mainly in three research directions: Thermoelectrics, Thermal Management, and Micro/nanofluidics. For thermoelectric research, we mainly focus on development of efficient nanostructured thermoelectric materials, fundamental understanding of phonon and electron transport in nanostructured materials, and fabrication of thermoelectric devices for waste heat harvesting. In the area of thermal management, we will explore the boiling heat transfer limits with microstructured surfaces and also develop novel thermal interface materials with low thermal resistance. As to micro/nanofluidic research, we aim to develop novel micro/nanofluidic devices for biomedical applications.
Electrical Power and Control Systems Laboratory
The electric power industry is undergoing a worldwide radical transition that is mainly driven by the significant generation from intermittent renewable sources (e.g. wind and solar) and the growing adoption of electric vehicles.
We explore environmentally friendly solutions that can provide system operator extra flexibility to integrate renewable generation and electric vehicle charging, including energy storage operation, price-responsive demand, and the Flexible AC Transmission Systems (FACTS). The overall objective is to improve the overall efficiency of the next-generation power system while maintaining system reliability and security.
Nano-Energy and Smart System Laboratory
As the development of the Internet of Things (IoT), trillions of widely-distributed devices are integrated for health monitoring, biomedical sensing, environmental protection, infrastructure monitoring, and security. The traditional technology for powering these devices is using batteries, which might not be an optimal solution due to the limited lifetime, difficulties for replacement and maintenance, and potential environmental issues. To provide a sustainable power solution, triboelectric nanogenerator (TENG) has been developed since 2012 for high-efficiency mechanical energy harvesting from ambient environment. The TENG has been demonstrated with some unique output characteristics, such as high-voltage output, fixed charge transfer amount, and high-efficiency for low-frequency energy harvesting. The proposed research in our lab will take advantages of these characteristics to power high-voltage applications, achieve controlled output performance, and effectively utilize the small-amount, low-frequency energy. Besides with TENG, we will also explore mechanical and thermal energy harvesting through newly developed mechanisms. These studies will facilitate applications of the emerging energy harvesters and set foundation for the development of the energy-efficient smart systems.
