AŞ's personal website

I have recieved my MS & BS degrees from Bilkent University Department of Computer Engineering
I'm currently collaborating with Dr. Ingo Wald, Dr. Stefan Zellmann, and Nate Morrical on multiple ray tracing and scientific visualization oriented papers.
Working under Intel Center of Excellence at University of Utah to develop a SYCL implementation of compression library ZFP.
Interned at Lawrance Livermore National Laboratory as Graduate Computing Scholar.
I'm also remotely-collaborating with Prof. Uğur Güdükbay and Serkan Demirci from Bilkent University on more rendering oriented papers.
