Bio

    I have now moved to Mobility, Networks and Systems group at Microsoft Research India. My new web page is located here.

    I received my PhD in Computer Science in Dec 2007 under the guidance of Prof. Samir Das and Prof. Himanshu Gupta. Prior to this, I received my Bachelors degree in Computer Science from Bangalore University (Univ Visvesvaraya College of Engg.) in Fall 2000 and Masters degree in CS from Stony Brook University in Spring 2003. Before my US study endeavor, I spent a short stint at Microsoft R&D center in Hyderabad. From Summer 2005, I worked for 2 years with the Networking Group at NEC Labs America in Princeton.

    My research is focused on wireless access networks - Wireless Mesh Networks (WMNs) and Wireless LANs (WLANs) - for large enterprise and campus deployments. I am working on issues related to performance, robustness, security, client mobility and real-time application support(VoIP and Video). I have also worked on some interesting problems in other areas: data aggregation in energy constrained sensor networks, and securing password based user authentication.
