RESEARCH INTERESTS
My research is focused on the design and (mostly theoretical) analysis of algorithms and data structures to address a variety of problems (mainly related to network applications). My main sub-area of interest is polynomial-time approximation algorithms. I also work(ed) on polynomial-time exact algorithms and data structures, exact/parameterized exponential-time algorithms, and distributed algorithms. I currently have 76 publications (28 journals) with 51 coauthorsAccording to Google Scholar, my papers received over 1700 citations and my h-index is 23.
