Short CV

Research
My fields of research cover the Industrial Internet of Things (IIoT), Cloud Computing and Privacy Enhancing Technologies (PETs). In particular, I am interested in security & privacy implications and the application and the design of secure computation. In particular, I look into privacy-preserving and privacy-enhancing technologies. Currently, I am mainly researching in the cluster of excellence "Internet of Production". I am the deputy workstream coordinator for CRD-A Workstream I (since April 2019). As a student assistant (2016-2018), I was involved in the TRINICS project to increase the consumer awareness of cloud services.

Background
Since June 2018, I am a researcher and Ph.D. student at the Chair of Communication and Distributed Systems. I am part of the Security and Privacy research group. In 2011, I began my studies in Computer Science at RWTH Aachen University, received my B.Sc. degree in 2014, and graduated with M.Sc. degree in 2018. In 2014, I studied abroad at Aalto University for one academic year. Besides, in 2015, I interned at the SECAN-Lab at the University of Luxembourg for six month where I worked on website fingerprinting in anonymization networks.

Awards
I received a stipend to attend RWC 2020. Furthermore, I was awarded the 1st prize of TDWI Award 2018 for the best master thesis in the area of analytics, big data, and business intelligence. Besides, in 2018, I received a Google Scholarship for my Ph.D. studies due to my academic achievements and my persistent demonstration of leadership. During my studies, as part of a Research Focus Class, our team's submission to the 2016 iDASH Genome Privacy & Security Competition was ranked runner-up and awarded with the HLI and Genecloud Award.
