Thodoris Sotiropoulos

Postdoctoral researcher, Department of Computer Science, ETH Zurich, Switzerland

I am a postdoctoral researcher in the Advanced Software Technologies group at ETH Zurich, under the guidance of Prof Zhendong Su. My research focuses on the design of appropriate abstractions that help examine the reliability of complex software, such as compilers, data-oriented systems, or software that heavily relies on the file system. I completed my PhD at the Athens University of Economics and Business working in the areas of programming languages, program analysis, and testing under the supervision of Prof Diomidis Spinellis. I hold an MSc with distinction in Advanced Computing from Imperial College London and I have previously worked as a software engineer at the Greek Research and Technology Network (GRNET). Recently, I was an intern at Amazon Web Services (AWS) where I worked on the design and implementation of static analysis techniques for detecting security issues. For my detailed CV, please follow this link.

My main research interests include programming languages, program analysis, and testing.
