Postdoctoral Research Fellow
The University of British Columbia, Vancouver, Canada
Advisors: Dr. Karthik Pattabiraman (ECE) and Dr. Aastha Mehta (CS).
ICS-Sniper (lead researcher and mentor)
- Designed and implemented the first targeted blackhole attack that exploits the metadata of encrypted ICS/OT network traffic.
- Developed the full analysis chain: feature extraction from TLS- and VPN-encapsulated SCADA traffic, recovery of control-loop periodicity, clustering to identify target flows, and selective packet dropping in live traffic.
- Built hardware and software testbeds (S-SWaT, H-SWaT) with Allen-Bradley PLCs, and evaluated network-layer mitigations such as traffic shaping.
- Led a five-member, multi-year project and co-authored a grant proposal awarded CAD 500K by the National Cybersecurity Consortium of Canada (2024).
- Delivered talks at Idaho National Laboratory and ETS Montreal, and reported progress to the consortium every quarter.
Security of AI/ML-enabled medical devices (researcher and mentor)
- Systematized the identification of inference-time security risks that emerge when AI/ML is integrated with legacy medical infrastructure.
- Defined threat models and built LLM- and RAG-based tools that identify these risks from a system's design, informed by MITRE ATT&CK and ATLAS.
- Extended the work to detector robustness: evasion attacks on DNN-based anomaly detectors, and risk-profiling defenses against them.
- Mentored PhD, MASc, undergraduate and capstone students, with collaborators at UBC, the University of Virginia and IIT Madras.
- Presented the work to industry executives at Medtronic, GE and Medcrypt, and to the FDA.
IoT privacy and information flow control (collaborating researcher)
- Contributed privacy research ideas to the group's IoT work.
- Co-authored Turnstile, a hybrid information flow control framework for GDPR-compliant IoT applications (EuroSys 2026).
- Co-authored ImmunoPlane, a middleware that brings adaptivity to distributed IoT applications (IoTDI 2024).
