RESEARCH

I am a third-year Ph.D. student at Cornell University. I work with Professor Christoph Studer, who is an Associate Professor at ETH Zurich and a Visiting Associate professor at Cornell University. My research is 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.
