Hi, I am Fatih! I am a fourth-year PhD Candidate in Electrical Engineering at NYU WIRELESS, New York University, under the supervision of Professor Shivendra Panwar. I received my Bachelor of Science degree in Electrical and Electronics Engineering from Bilkent University in 2022. My current research interests include transport- and network-layer solutions, congestion control, low-latency networking, and data center networking.

Here’s my résumé.
