RESEARCH

I am a fourth-year Ph.D. student at Cornell University. I work on baseband algorithms for beyond 5G multi-antenna wireless communication systems. More broadly, I am interested in applying statistical signal processing techniques to model signals corrupted by noise and hardware impairments, and exploiting such models in order to design computationally-efficient algorithms that estimate the signals of interest.

My advisor is Professor Christoph Studer, Associate Professor at ETH Zurich and Visiting Associate professor at Cornell University.
