My Resume

Goal
Use technology and research to create some positive change for humanity.
Research Objective

Enhance Situational Awareness in large-scale, complex, distributed systems using a combination of knowledge-based and data-driven approaches.

This has immediate applications in areas like CyberSecurity, Smart Grids, Networked Experiment Testbeds and Social Networks (to name a few) where the scale and complexity of such systems, combined with the exaflood of data is creating challenges and opportunities that may have not been witnessed since Gutenberg. Situational Awareness will aid users of these systems in making better sense of the environment they are in and help them make better decisions.

Education Summary
  • Pursuing a PhD in Computer Science advised by Dr. Clifford Neuman at University of Southern California (3rd Year).
  • Masters in Computer Science (with specialization in Computer Security) from University of Southern California, LA (GPA: 3.91/4.0)
  • Bachelor of Engineering in Computer Science from Pune Institute of Computer Technology, Pune, India. (GPA : 3.78 / 4.0)
  • Relevant Skills
    Fair understanding of Computer Security, Secure Programming, Mathematical Logic, Data Mining, Algorithms, Computer Networks, Operating System Internals (esp. Linux), Malware reverse engineering, Vulnerability analysis, System programming (esp. debuggers) and a variety of hands-on experience with networking equipment and system administration. Have used C, Assembly, Python, Java, JavaScript extensively.

    Graduate Research Assistant (USC-ISI / Los Angeles, USA / Jun 2007 - Present)
    1. ThirdEye
    2. ThirdEye is my attempt to address the challenge of making sense of the vast amounts of data collected by information systems. ThirdEye creates Situational Awareness by enabling users/operators of such systems to build security, diagnostic, analytic and decision-making applications. This work is currently being done in the context of two domains: Networking Testbeds and Smart Grids.
    3. Knowledge Plane Project (with John Wrocklawski, Karen Sollins and Ted Faber)
      • The high level objective of the research was to build a diagnostic system for intrusion detectors in a Knowledge Plane like environment. Such a diagnostic system would then help distributed intrusion detection systems to effectively correlate detection reports from various sources.
      • There were 4 approaches investigated:
        • Passive learning - In this approach, an unsupervised learning model (Hidden Markov Model) was used for inferring detector trust using only detector ouputs from weak-local detectors.
        • Active Probing - In this approach, active probes or tests are fired from a central evaluator towards a detector and its responses are benchmarked against expected results.
        • Systematic Testing - This mechanism aims at systematically testing a detector offline for True Positives and False Positives by generating tests relevant to the deployment context of a detector.
        • Ensemble Framework - This approach uses an ensemble of detectors (at a single location or distributed) to find a global consensus. This approach takes a slightly different approach to the diagnostic problem as it tries to build a complete intrusion detection system instead of just building a diagnostic system.
    4. Worked on testing the Federation Architecture for DETER by running a worm experiment across three DETER sites.
