I am William Smith Foundation Dean's Professor of Mechanical Engineering at Worcester Polytechnic Institute. Since joining WPI, I have been very active in research. Currently, my lab focuses on the study of new electrodes and materials for energy storage, including lithium ion batteries, supercapacitors, flow batteries, battery manufacturing, battery safety and recycle, and fundamental electrochemistry. This research can lead to energy storage with high energy density, high power density, long life, low cost, and high safety. In addition to fundamental research, I have commercialized the technologies developed in my lab.
