1. Heat Transfer in Additive Manufacturing

Heat transfer plays a key role in metal- and polymer-based additive manufacturing (AM) processes. We carry out experimental measurements of thermal transport during AM processes, which we complement with rigorous theoretical modeling and simulations. We also carry out experiments to understand the process-microstructure-property relationships in additively manufactured parts, particularly in the context of heat transfer properties.

2. Coupled, multi-physics phenomena in electrochemical energy conversion devices

Energy conversion and storage in Li-ion cells is a highly coupled, multiphysics phenomena of much technological importance, due to applications in electric vehicles, electronics and defense systems. We are carrying out experiments to understand thermal transport in Li-ion cells. We are also developing integrated models to understand the interactions between thermal, electrical and electrochemical phenomena in Li-ion cells.

3. Thermal transport in 3D ICs

Heat dissipation in three-dimensional integrated circuits is a significant technological challenge, which has contributed to the relative lack of wide adoption of this technology despite a tremendous amount of research in past decade or two. We are carrying out experiments to measure key thermal characteristics of 3D ICs and are developing analytical models to understand thermal transport in a 3D IC.

4. Thermal transport in biological microsystems

Despite the remarkable temperature sensitivity of organisms, only very limited work has been carried out on understanding thermal effects of biological microsystems such as cells, and macromolecules such as DNA and proteins. In a series of experiments, we are seeking to utilize microfabricated heater structures to thermally probe cells, DNA and proteins.

We have an interest in understanding and developing temperature measurement methods, both for microsystems as well as for more conventional engineering systems. We are developing remote, non-intrusive temperature measurement techniques for engineering systems. We are also currently involved in a collaborative project for distributed, wireless measurement of temperature in power plant boilers.
