Passionate about leveraging tech & AI for positive change, I specialize in developing innovative solutions to complex problems.

Assistant Professor

Rochester Institute of Technology

At RIT I researched networks and security, and was also interested in fault-tolerance, distributed systems, and ad-hoc networks. Some of our questions had technical answers; some had political answers; and some had no answers at all.

For example, WHY do computers route by IP address and not directly by MAC address? (IP addresses can be aggregated - one routing table entry can route to a whole prefix.) But then, why are routing tables still so large? Why did MPLS not solve this problem? What would it take to solve it? And so on.

In this period, I published actively (including venues such as PETS, ACSAC, and INFOCOM), started a research group and brought in grant funding, and mentored and graduated UG, PG and Ph.D. students. Some of my former students went on to become Asst Profs as well.

Assistant Professor (Cybersecurity)

IIIT Delhi

After completing my PhD, I thought I'd give back to India, and went home to teach. But in my four years at IIIT, I learned more than I taught. Most importantly, I learned that teaching isn't just about knowing the material - it's about relationships. (You have to challenge your people and at the same time make them feel safe.) I'm still learning how, and probably always will.

I stayed active in research as well (our last paper won Best Paper at Securecomm - congrats Dev!) and I made a lot of friends. Mentors, colleagues, students. My own graduate students (two Assistant Professors); undergrads who went on to UC Berkeley, Oxford, and U Penn; a PM for Google Maps.

Assistant Professor (Teaching)

University of Texas at Austin

My Ph.D. work was on security policies and access controls, and how to create, check, and optimize them. I also created a theoretical basis for network mapping with traceroute etc. In my later work, I ended up combining these threads – how crafted packets can be used for traceroute, how they can fool firewalls, etc.

In addition to my dissertation research, I also studied the game theory of distributed systems, and published on security theory (the Dolev-Yao adversary). I also designed secure protocols for two-way and anonymous internet authentication, for security in sensor networks, and (as a co-author) for integrity and non-repudiation.

Ph.D. Candidate.

I'm an engineer, researcher, and educator in Networks and Cybersecurity. I have ten years' experience creating and leading research projects, coordinating small teams, presenting reports, and teaching.

Other interests: Distributed Systems, Protocols, Network Science, and Algorithms (string matching, sequence alignment, etc.)

PROJECTS:
1. Data-plane network security. - The P4 language allows SDN switches to parse packets and extract header fields – but not payload fields. It's "not for DPI". Or is it? We built DeeP4R, a system that actually *does* perform DPI on P4. We currently have a limited next-gen firewall, and aim to explore intrusion detection, DNS server, and other use cases.

2. Internet Security. - Do network outages and censors affect users *in other countries*? Can we route around them using overlays or CDN? Or, in the worst case (no disruption-free paths), can we "punch through" the blockage? Our Decoy Routing system, SiegeBreaker, is one way to do this.

3. Meshed Tree Protocol. -  In Data Centers etc., we no longer compute loop-free paths or multi-paths at L2; it is all done in L3.  *Can* a fast, resilient network backplane at L2 outperform L3 solutions? 

SKILLS:
1. Communication – Ten years of experience in teaching, presentation, and technical and non-technical writing. Ratings of 4.5+/ 5 as a teacher.

2. CyberSecurity – Research experience in Firewalls, Intrusion Detection, Internet Security (BGP, DNS).
Five years of experience teaching skills (VM lab, firewall/proxy, flow tools, Snort/Zeek, VPN etc.) 

3. Networks – Research experience with SDN, Internet Measurement, and Protocols. 
Five years of experience teaching skills (Wireshark/Scapy, Traceroute, Layer-2/Layer-3/overlay networks, software-defined and data-center networks etc.)
