I got a PhD at the UT back in 1988 in Graph Theory, a subarea of Discrete Mathematics. After that, I stayed at the UT as a lecturer, senior lecturer and professor in Discrete Mathematics until 2004. That year I moved to Durham University in the Northeast of England to take up a position as a Chair (full professor) in Theoretical Computer Science. There I have helped to build up the strong ACiD group in Algorithms and Complexity. In 2011, I returned to the UT as a professor in Programmable Nanosystems. My current research is a mixture of Structural Graph Theory, Algorithmic Graph Theory, Applications of Graph Theory, Computational Complexity, and Unconventional Computing, in particular Neuromorphic Computing and Brain Inspired Computing.
