Research Interests:
Primarily, I study quantum error correcting codes at finite temperature. This involves the development of algorithms and simulations to characterize the lifetimes and noise thresholds of different systems. Most of my work has been on stabilizer codes like the Toric Code.
More recently, I have become interested in various topics in machine learning. I've studied the geometric properties of neural networks, and I would like to leverage the tools of statistical physics to better understand the expressive power of specific machine learning architectures.
