Seongkyun Im is an Assistant Professor in the Aerospace and Mechanical Engineering Department.  He was an Assistant Professor in the Mechanical Engineering Department at Worcester Polytechnic Institute prior to joining the University of Notre Dame.  He received his Ph.D. and M.S. degrees in Mechanical Engineering from Stanford University in 2013 and 2009, respectively.  His graduate research focused on scramjet unstart phenomena and its mitigation using plasma-assisted flow control.  He worked for one and a half year as a post-doctora researcher at Stanford University, developing scalar imaging-based velocimetry.

Summary of Activities/Interests

Dr. Im’s research interests and expertise are in propulsion, high-speed aerodynamics, and fire.  The current projects in his research group include scramjet inlet/isolator design, laser-assisted ignition for scramjet cold start, scramjet unstart, and design of portable large scale wind tunnel for wildfire research.
