Who I Am

About Me

Reza M. Asiyabi
Edinburgh, UK
Postdoctoral Research Associate
PhD, Marie Curie Fellow
reza.asiyabi@ed.ac.uk

I'm a Postdoctoral Research Associate at the University of Edinburgh, building interpretable, physics-aware AI for Earth Observation. Funded by the UK National Centre for Earth Observation (NCEO) and the UKRI SECO project, my current work focuses on domain-aware deep learning for radar–vegetation interactions — teaching AI to interpret forests through backscatter physics rather than pattern-matching alone.

Before Edinburgh, I completed a Marie Curie–funded PhD at the University POLITEHNICA of Bucharest (MENELAOS-NT network), developing complex-valued neural networks for SAR data processing. I then joined Stanford University's Center on Food Security and the Environment to build the Market Activity Index (MAI) — a remote sensing system that detects rural markets in low-income countries from high-resolution satellite imagery.

My research sits at the intersection of theoretical depth and real-world impact: from land-cover analysis and biomass estimation to neural data compression and geospatial multimodal language models. I've published across leading ML and EO venues, won competitive fellowships, and built methods that bridge rigorous physics with practical impact. I thrive in interdisciplinary teams where different domains push each other forward.
