Education • Aug 1997-Dec 2002: Doctor of Philosophy (PhD) in Computer Science University of California at Berkeley, CA Research advisor: Prof. Randy H. Katz Thesis topic: An Architecture for Performance and Availability Constrained Composition of Services in the Wide-Area Internet • Aug 1997-May 1999: Master of Science (M.S.) in Computer Science University of California at Berkeley, CA Research advisor: Prof. Randy H. Katz Thesis topic: Personal Mobility in the ICEBERG Integrated Communication Network • Aug 1993-May 1997: Bachelor of Technology (B. Tech) in Computer Science & Engineering Indian Institute of Technology - Madras, India Advisor: Prof. C. R. Muthukrishnan CGPA: 9.75/10 1 Research Experience • Professor, Department of CSE, Indian Institute of Technology - Bombay, INDIA, Sep 2014 to present. Associate Professor, Department of CSE, Indian Institute of Technology - Bombay, INDIA, Feb 2009 to Aug 2014. Assistant Professor, Department of CSE, Indian Institute of Technology - Bombay, INDIA, Jul 2007 to Feb 2009. – In the Witals project, our research group is exploring WiFi performance diagnosis, especially in dense situations. – As part of the CARTS (Communication Assisted Road Transportation System) project, I am looking at technical issues in the use of wireless communication to improve road traffic in Indian conditions. – In the Smart-Teaching project, I am interested in looking at technical and pedagogical issues which arise when students in a large classroom use smart devices (phones, tablets) for improved classroom interaction. – I worked on the FRACTEL project, which extends my earlier work on RuralNet, by considering a mesh network consisting of long-distance as well as short-distance links. The goal of FRACTEL is to provide scalable and predictable mesh network performance. – I worked on Lo3, a low-power, low-cost, local communication system for village settings, based on a mesh network of IEEE 802.15.4 radios. • Visiting Scientist, AirTight Networks, Mountainview, CA, USA, June 2012 to June 2013 I worked on various Wi-Fi performance related issues as part of AirTight’s R&D team • Visiting Researcher, Microsoft Research India (MSRI), May-Jul 2008 We identified future areas of collaboration with researchers at MSRI. Specifically, two areas of common interest are: (1) Lo3 (Low-cost, Low-power, Local voice and messaging), and (2) CARTS (Communication Assisted Road Transportation System). • Visiting Researcher, Alcatel-Lucent Bell Labs, Bangalore, India, May-Jul 2007 I worked on the above-mentioned FRACTEL project, in collaboration with researchers at Bell Labs, Bangalore. • Assistant Professor, Department of CSE, Indian Institute of Technology - Kanpur, INDIA, Jun 2003 to Jul 2007. I have worked on the RuralNet (Digital Gangetic Plains) project, exploring the use of IEEE 802.11 for low-cost, long-distance rural networking. • Visiting Researcher, CalIT2, University of California at San Diego, Jul-Dec 2004. I worked on exploring the use of the “claims allocation” literature in the domain of economics, to network scheduling. • Graduate Student Researcher, SAHARA Project, University of California at Berkeley, EECS Department, Summer 2001 to Fall 2002. As a senior graduate student, I played an active part in the development of the SAHARA architecture. My PhD thesis explored a specific form of service composition – the central theme of the SAHARA project. 2 • Summer Intern, IBM T.J.Watson Research Center, New York, 1999. I worked on issues related to service discovery and network layering in Bluetooth scatternets. (See paper titled “Arguments for Cross-layer optimizations in Bluetooth Scatternets” below). • Graduate Student Researcher, ICEBERG Project, University of California at Berkeley, EECS Department, Summer 1998 to Summer 2001. – I have been part of the team involved with the design of ICEBERG – an Internetbased architecture for integration of services across heterogeneous access networks and devices. – I have played a lead role in the two code releases of different versions of ICEBERG software. – In Summer 1998, I worked on building a gateway to interface cell-phones on a GSM wireless network to the Internet. This was done as part of testbed development for the ICEBERG project. – I worked on the design and implementation of the “Universal Inbox” for my Master’s thesis. • Graduate Operating Systems Course, University of California at Berkeley, Fall 1997. I worked on a project that looked at techniques for reordering data on the fly in data processing applications. The idea was to reorder the data based on continuous user feedback so that the user has control over which data items are processed first. (See under “publications” below).
