profile picture

I’m a Research Associate and PhD student at the Mobile Cloud Computing research group at Technische Universität Berlin and Einstein Center Digital Future. My research interests include Fog and Edge Computing, modern software architectures such as microservices and serverless compute, and novel LEO satellite networks. Currently, I’m also a research associate intern at Hewlett Packard Labs in Milpitas, California.

I received my Master of Science in Computer Science from Technische Universität Berlin in 2019 with a 1.0 grade (equiv. to 4.0 GPA). While studying in Berlin, I worked as a Systems Administrator at audibene/hear.com.
