Problems I keep returning to

My work studies how machine learning can infer latent state from noisy, heterogeneous data. I have worked across passive sensing, clinical movement data, biomedical process variables, geospatial risk, and healthcare datasets. The common problem is measurement: how to recover useful structure from signals that are incomplete, indirect, and collected outside ideal experimental conditions.

Human behavior and physiological intelligence

Human behavior produces continuous low-friction signals: movement, sleep-wake timing, device interaction, motor control, and changes in daily rhythm. I model these signals to estimate behavioral, physiological, and clinical state. This area sits closest to my training in computer science and neuroscience, especially in passive sensing, digital phenotyping, and clinically relevant prediction.

Healthcare decision systems

Healthcare data is delayed, siloed, and usually analyzed after the most important decisions have already been made. At Avenir, I build systems that integrate claims, benefits, vendor, and population-level data so organizations can identify cost drivers, risk concentration, and intervention opportunities with more precision. I am interested in how AI can support decision-making under uncertainty, not just summarize existing reports.

AI for scientific and biological discovery

Biological and engineered systems are nonlinear, noisy, and expensive to probe experimentally. I use interpretable machine learning to model these systems, including biofabrication, biomaterials, environmental exposure, and public-health risk. The goal is to make experimentation more directed by identifying which variables appear to matter, where uncertainty remains, and what should be tested next.

About

I develop machine learning systems for human and biological data.

Hi, I'm Ari, a researcher and technical founder working across machine learning, neuroscience, and biological systems. I am interested in a recurring technical problem: how to infer meaningful state from noisy, incomplete data collected in real-world settings.

At MIT, my research focused on digital phenotyping and on-device inference, including models for circadian rhythm, smartphone behavior, and clinically relevant passive signals. I have also worked on real-time detection of Parkinson's freezing of gait, interpretable ML for biofabrication, geospatial modeling for public-health risk, and computational modeling for biomedical systems.

I am now co-founding Avenir, a healthcare decision systems company applying AI to claims, benefits, vendor, and population health data. The work extends a broader research interest of mine: building models that help people reason under uncertainty when the data is messy, delayed, and operationally consequential.

Across these projects, I care about models that work under real constraints: limited labels, noisy measurement, heterogeneous data sources, edge deployment, clinical or organizational stakes, and the need to explain why a model made a prediction.

I'm Honduran-Turkish, grew up in Rhode Island, and now live in San Francisco. I speak Spanish and am learning Italian, Korean, and Chinese. Outside research and company-building, I built a Spanish-language AI education nonprofit with partners across more than 20 Latin American universities, have spoken internationally about research and entrepreneurship, and model part-time.
