Research interests

The primary research interest of our group is in thermoelectric materials, with a specific focus on the performance improvements of thermoelectric materials for use in flexible electronics. We synthesize and characterize composite thermoelectrics, and improve their performance using appropriate additives and materials processing techniques. We use these materials to print flexible electronic devices (e.g., thermoelectric generators). These devices find applications in wireless sensor networks, implantable medical devices, automobile engines, condition-monitoring sensors, and military equipment, among others. We focus on cost-effective and large-scale production worthy manufacturing techniques.

We are also interested in performance enhancement of rechargeable batteries that suffer from dendrite growth. By inhibiting dendrite growth in these batteries, we aspire to increase the battery’s life cycle.
