  • Update Fall 2019: Graduated with a PhD in Computer Engineering. Joining Intel Corporation, OR USA.

I'm a Ph.D. candidate in Computer Engineering working with Prof. Seda Ogrenci-Memik at Northwestern University in Evanston Illinois, USA. My research is focused on Associative Memory design, verification, and testing; and in the fabrication and integration of thin-film thermocouples in 3D Integrated Circuits for temperature measurement and thermal management. I have previously worked at Intel Corporation OR U.S.A, Fermilab Batavia IL U.S.A., and C.E.R.N. Geneva Switzerland.
