Clinical ML scientist | Stroke, rehab and movement biomarkers | Biostatistics | PhD, Harvard OEB Associate

Profile Summary

Scientist working in machine learning for clinical assessment, with a PhD in evolutionary and environmental biology (University of Haifa, summa cum laude) and an Associate appointment at Harvard University's Department of Organismic and Evolutionary Biology. More than 30 publications (1,100+ citations, h-index 15 on Google Scholar) across clinical machine learning, evolutionary biology and sensory ecology. Founder of CVAid Medical, an AI stroke-diagnosis company backed by Philips, and named inventor on two issued U.S. patents and one published U.S. patent application.

My clinical work covers machine-learning fall-risk assessment, 3D motion capture for Fugl-Meyer stroke testing, and movement-based assessment of Parkinson's disease. My biological work covers developmental instability, fluctuating asymmetry, symmetry perception and ecological adaptation.

Services I offer:
- Clinical validation of ML and digital-biomarker models: study design, reference standards, sensitivity, specificity, calibration, spectrum bias.
- Statistical analysis and experimental design for biomedical and ecological data.
- Computer-vision and sensor-based movement assessment for stroke, rehabilitation, Parkinson's disease and fall risk.
- Critical scientific review of manuscripts, grant proposals, technical reports and due-diligence material.
- Consulting in evolutionary biology, ecology and morphometrics.
