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 subarea of interest is polynomialtime approximation algorithms. I also work(ed) on polynomialtime exact algorithms and data structures, exact/parameterized exponentialtime algorithms, and distributed algorithms. I currently have 85 publications (33 journals) with 65 coauthors. According to Google Scholar, my papers received over 1900 citations and my hindex is 25.
