About Me

Hi, my name’s Cenk, and I’m a Ph.D. candidate in quantum computing. I love working on multidisciplinary projects, and in fact, this is what brought me to quantum computing. I enjoy working with people from all around the world and am always looking for new collaboration opportunities to broaden my horizons. Below is a non-exhaustive list of my current research interests. Feel free to reach out via your favorite platform.

Research Interests:

  • Quantum machine learning (QML); trainability and expressive capacity of QML models, barren plateaus, warm starting.
  • Generative learning with QML
  • Geometric machine learning; representation theory, category theory
  • Understanding hardware noise to maximize utility of current hardware
  • Physics simulations with Quantum Computing
  • High Energy Physics applications of Quantum Computing
