Research & Publications

I am interested in heat transfer, liquid-vapor phase change phenomena, flow visualization, and additive manufacturing. During my Ph.D., I have worked to reveal key insights into fundamental thermofluidic physics of the operation principles of a plate heat exchanger, which we see as a thermal transport device with complex micro- and minichannels.

Currently I am an Assistant Professor at the University of Alabama. I was a postdoctoral scholar at the Stanford Nanoheat Laboratory led by Prof. Kenneth Goodson. During my Ph.D., I conducted research as a member of Prof. Anthony Jacobi's research group at the Air Conditioning and Refrigeration Center (ACRC), Mechanical Science and Engineering, University of Illinois.
