About

I'm Alper Sahistan(Şahıstan), a PhD student at SCI Institute at the University of Utah. My research areas include ray tracing, volume rendering, visualization and computer graphics. I am also interested in HPC and computational geometry.
Further Information
  • 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.
