Hi! I am an Assistant Professor at Koç University Electrical and Electronics Engineering. I explore and exploit nonlinear dynamics in optics, generate high-power ultrashort pulses and use them to develop photonic technologies and solutions. For open positions and ongoing projects, see the web pages of Laboratory of Photonic Technologies (LPT).

 

Research interests:
I am working on photonics with a focus on “Optics for AI and AI for Optics”. I study and utilize nonlinear wave dynamics for:
  • Ultrafast optics
  • Fiber optics and lasers
  • Optical computing
  • Photonic neural networks
  • Ultrafast imaging
  • Frequency conversion
