Road Safety & Active Mobility Researcher
Hi, I'm Rahul
Roads kill. I research why - and how to change that.
For over a decade, I've studied the small decisions - a glance, a hesitation, a missed signal - that separate a safe crossing from a fatal one. My research spans pedestrian behaviour, child safety, driver psychology, and crash risk across India and the United States.
I believe the best science doesn't stay on the page - it changes how we build streets and protect the people who use them.

ExploreA bit about my story
For over a decade I've watched how people actually cross streets - in Kolkata, Guwahati, Mumbai and Kentucky - and asked why so many of those crossings end badly.
Today I'm a Project Research Scientist at IIT Bombay. My work blends field data, statistics and machine learning to make streets safer for people who walk, cycle and ride - especially children and people with disabilities.
What I'm curious about right now
- Walkable & cyclable streets
- Pedestrian & cyclist safety in Global South cities
- Child road safety
- Night-time crash risk
- Mobility for blind & differently-abled pedestrians
- The real cost of free parking
