Biography

Temesghen Kahsai is a Research Scientist at NASA Ames employed by CMU, where he has been a member of the Robust Software Engineering group since 2013. 

His research interests are in the automated software analysis for complex safety and mission critical software. From 2012 to 2013, he was a software engineer at Skype (Microsoft), where he worked on the mobile core division. From 2010 to 2012, he was a postdoctoral research scholar at the University of Iowa, where he worked on scaling SMT-based model checking. He is currently leading three research projects funded by NASA and NSF on contract-based verification of outsourced flight critical systems, compositional analysis of heterogeneous software protocol stack and credible auto-coding of embedded systems. He is also a co-investigator in a DARPA-funded research project on ’space/time analysis for cybersecurity’.
