Kyungmin Baik, 2010 Postdoctoral Scholar


Kyungmin Baik ( received B.S. and M.S. degrees in physics from Korea University (, Seoul, South Korea, in 1996 and 2000, respectively, and a Ph.D. degree in physics from Washington State University (, Pullman, in 2008 under the supervision of Dr. Philip L. Marston ( His research area for his M.S. thesis was the detection of muon among cosmic rays by using prototype of Resistive Plate Chamber. In his Ph. D., he accomplished several projects funded by ONR ( such as: 1) Backscattering by partially exposed object in the flat interface, 2) Backscattering by truncated cone (frustum) as a function of tilt angle and its interpretation using ray theory, 3) Acoustic holography of various cylinders, 4) Synthetic Aperture Sonar imaging of various cylinders, 5) Simulation using Method of Moments and Finite Element Method.

After receiving his Ph.D. in 2008, Kyungmin worked as a research fellow at the Institute of Sound and Vibration Research (, University of Southampton in the U.K.  He did the project with Dr. Timothy G. Leighton ( and Dr. Jian Jiang ( for bubble detection, which was funded by Oak Ridge National Laboratory ( in Tennessee. The object of the project was the measurement of acoustic bubbles in liquid mercury which causes cavitation inside the steel pipeline of Spallation Neutron Source, which is the largest neutron source in the world. In this project, he combined the elastic theory in waveguide with bubble acoustics to estimate void fraction.

 He joined WHOI as an Ocean Life Institute Postdoctoral scholar in July of 2010. Currently, Kyungmin is working with the scattering by swim-bladder fish for detection purposes, which is important since 1) acoustic signal by fishery needs to be classified to isolate from the military signals, 2) it gives valuable information to ecologist, and 3) fish is a food source. His long-term goal at WHOI is the application of acoustic scattering theory and imaging technique to real ocean environment.
