Building ML systems that turn physiological signals into clinical insight

I'm a Machine Learning Scientist and Biomedical Researcher with 5+ years building multimodal AI and signal-processing systems for neural, wearable, and clinical data. My pipelines span cohorts exceeding 2 million patients — from actigraphy-derived sleep biomarkers that predict Parkinson's disease a decade before diagnosis, to population-scale causal inference for stroke and dementia prevention.

Currently a Research Scientist at Mount Sinai. Previously a Research Assistant in the Mignot Laboratory at Stanford. I hold an MS in Epidemiology & Clinical Research from Stanford, an MS in Biomedical Engineering from the Technical University of Denmark, and a BS in Biomedical Engineering from the University of Genoa.

Achievements that matter

Three proof points of solving difficult technical problems at scale—published, externally validated, and reproducible.

1

Population-scale AI for Parkinson's disease

End-to-end machine learning on 87,510 UK Biobank participants

Built an end-to-end machine learning and survival modeling pipeline to identify early markers of Parkinson's disease using 7-night wrist accelerometry from the UK Biobank. I engineered the full Python framework—including feature engineering, Cox survival analysis, inverse probability weighting, SHAP explainability, and reproducible pipelines—to detect disease years before clinical diagnosis. The model identified individuals with a 4.69× higher risk of Parkinson's disease over ~10 years, establishing scalable wearable biomarkers for neurodegenerative disease.

Competitive grant + clinical publication

$250,000 ResMed grant for objective Narcolepsy screening

Secured a $250,000 competitive research grant from ResMed to develop machine learning methods for objective Narcolepsy type 1 screening. I led the machine learning methodology, implementing nested cross-validation and Bayesian hyperparameter optimization to build models achieving an AUC of 0.996 and 99.2% specificity. The work was published in the peer-reviewed journal Sleep, demonstrating successful translation of AI research into clinically applicable diagnostics.

Novel computer vision algorithm

Automated wound-healing quantification without annotated data

Developed a novel two-stage computer vision pipeline for automated wound-healing quantification that combined variance-based segmentation with temporal continuity modeling, eliminating the need for annotated training data. I engineered the complete Python framework with quality control, parallel processing, and extraction of biologically meaningful metrics across 134 microscopy experiments. The pipeline substantially reduced manual analysis while enabling reproducible, high-throughput phenotypic screening for biomedical research.
