I am an associate professor in the Department of Astronomy and Astrophysics at the University of Toronto, Canada.

Prior to this position from the fall of 2003, I was a Robert A. Millikan Postdoctoral Fellow for Experimental Astrophysics in the Division of Physics, Mathematics and Astronomy (PMA) at Caltech. In the PMA division, I worked in the Space Radiation Laboratory (SRL) in the Physics Department. My faculty host was Fiona Harrison in SRL/Physics/ Astronomy. I also worked with Keith Matthews and Tom Soifer in the Infrared Army/Physics.

I was a graduate student at Cornell University in 1998-2003 where I worked in the Infrared Astrophysics Group of the Astronomy Department. My thesis advisers were Stephen Eikenberry (who moved to Florida later) and Jim Houck.

I went to Seoul National University at Seoul, Korea, for my college. I worked with Prof. Bon-Chul Koo in Astronomy there.
