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 thesis work focuses
on the origins of heavy tails and long-range dependence with
application to information networks, the design of scheduling
algorithms for communication networks, and the network performance modeling
and reliability evaluation.
Here is my Curriculum
Vitae and thesis.
My
advisor at Columbia University is Prof. Predrag Jelenkovic.
Now I have moved to Ohio State University working with Prof. Ness Shroff
as a Postdoctoral Researcher.
You
can get a rough idea about my thesis work by reading my research statement. For more
details please read the short
paper based on my thesis.
