Biography
I am an Associate Professor of Electrical and Electronics Engineering at METU, and the principal investigator of the Signal Processing And Computational sEnsing (SPACE) Lab. Before joining METU, I was a Post-Doctoral Research Associate with the NASA Goddard Space Flight Center, where I worked on the development of novel spectral imaging techniques for high-resolution solar imaging.
I received the Ph.D. degree from the University of Illinois at Urbana-Champaign (UIUC) in 2014, and the B.S. and M.S. degrees from Bilkent University, in 2007 and 2009, respectively. At UIUC, I was selected to the “List of Teachers Ranked as Excellent by Their Students”, and was a recipient of the Professor Kung Chie Yeh Endowed Fellowship in 2012, and a NASA Earth and Space Science Fellowship from 2012 to 2014.
