About me

I am a doctoral researcher at the Stochastic Modeling and Analysis of Communication Systems (SMACS) group at Ghent University (UGent).

I received my MSc degree in Mathematics in June 2017 from Ghent University. Since Octobre 2017 I am pursueing a PhD in (Mathematical) Engineering at Ghent University under supervision of em. prof. dr. ir. Herwig Bruneel, prof. dr. ir. Joris Walraevens and prof. dr. Dieter Fiems.

My research area is situated in Queueing Theory which is one of the oldest and most notable subbranches of applied probabilty. Broadly speaking, my research deals with the analysis of stochastic processes with applications to queueing systems. During my research, I focus on various techniques such as transform methods (probability generating functions and Laplace transforms), and complex function theory (singularity analysis and boundary value problems).
