   Neural integral control barrier functions for unknown nonlinear systems · code

   • +Implemented the full safety filter: Neural ODE dynamics, an imitation-learned policy, learned barriers and a QP with input constraints.
   • +Forward-invariance-aware labeling cut closed-loop input-constraint violations from 0.80% to 0.00%.
   • +On an F1TENTH racing model, reduced crashes on held-out tracks from 12/200 to 0/200.

2. M.Tech Thesis, ABV-IIITM GwaliorDec 2025 - now

   Real2Sim trajectory style transfer in CARLA, advised by Dr. Rahul Kala · code

   • +Mapped real Gwalior traffic into CARLA Town10HD and curated 5,212 scenarios across 6 maneuvers.
   • +Cut replay tracking error from 5.9 m to under 0.3 m with time-synchronized PID and road-aligned spawns.

3. Research Intern, iHub-Data, IIIT HyderabadDec 2024 - Nov 2025

   Safety-aware synthetic scenario generation for Indian traffic

   • +Built spawn correction and TTC-based collision avoidance for real-to-sim scenes in CARLA.
   • +Trained a SegFormer-B1 behavior cloning model on ~66,000 image-command pairs.
