Hongyi Zhang （张宏毅）
I am a fifth-year Ph.D. student in the Department of Brain and Cognitive Sciences at MIT working with Prof. Suvrit Sra.
I am also affiliated with LIDS and the Machine Learning Group at MIT.
I aim to utilize mathematical insights from high-dimensional statistics and high-dimensional geometry to advance machine learning and nonlinear optimization. I am interested in machine learning and, more broadly, modeling and solving real world computational problems.
