I am a third-year PhD student at UCL’s SpaceTimeLab, supervised by Dr James Haworth, Dr Aldo Lipani, and Dr Stefano Cavazzi. My research is funded by UKRI (EPSRC) and Ordnance Survey (OS).

I work on bridging natural language intent and structured geospatial data by measuring how people ask, see, and act in space. My research quantifies human spatial intent, salience, and say–do gaps using crowdsourced data and street-level imagery, with the goal of turning observed inconsistencies into concrete design requirements for geospatial systems. I apply these insights to perception-aware routing and to automated extraction of geographic concepts from web-scale, non-traditional datasets.

I am co-founder and CTO of Safest Way, a Geovation-backed startup developing safety-centric pedestrian navigation. Read about it in The Conversation.
