My
advisor is Predrag
Jelenkovic. My research interest lies in the mathematical foundations
of information networks and service systems, aiming at obtaining new insights and creating better
designs, especially when uncertainty is an essential part of the studied objects, e.g., for
computer networks and risk management systems. My dissertation work focuses on
understanding the origins of heavy-tailed (power law) distributions and designing
new adaptive (self-organizing) scheduling algorithms for the heavy-tailed environment.
Here is my Curriculum Vitae.
