I am Lecturer (equivalent to Assistant Professor) at Imperial College London, where I am part of the Communication and Signal Processing Group within the Department of Electrical and Electronic Engineering.

My research interests focus around the intersection of machine learning (theory), optimization and network science. More details are available under the publications tab.

Before joining Imperial in 2021, I was Postdoctoral Researcher at the Adaptive Systems Laboratory at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. I obtained my PhD from the University of California, Los Angeles (UCLA) in 2019, and completed my undergraduate degree with the Signal Processing Group at the Technical University, Darmstadt in Germany in 2013. A formal biography as well as academic CV are available here.

I am always looking for driven students and postdocs to work with. Please check the openings tab for details.
