Jun.-Prof. Dr.-Ing. Amr Rizk
I am a Juniorprofessor at Ulm University covering the topics of connected mobility and high performance communication networks. Previsouly, I was an Athene Young Investigator (Independent Research Group head) at the TU Darmstadt until July 2019. From Feb. 2016 to July 2019 I was also head the Adaptive Overlay Communications group at the Multimedia Communications Lab of the TU Darmstadt. As a Post-Doctoral researcher I was affiliated with the Department of Computer Science at the University of Warwick, U.K. (2014), and the University of Massachusetts Amherst, USA (2015). I obtained my Dr.-Ing. degree with distinction at the Leibniz Universität Hannover in 2013.
My research focus lies on stochastic modeling and optimization of networked systems. To this end, I develop methods and techniques in the areas of Queuing Theory and Network Calculus. I apply these analytical tools for the design, quantitative analysis and control of various connected systems such as wired and wireless communication systems, as well as, industrial automation. Particular applications of my work include:
- Hardware-accelerated Networking
- Multi-interface Communication (http://progmp.net/)
- Volumetric Streaming
- Adaptive and self-driving Networks
