Resident physician · since June 2026
PGY-1 in internal medicine at University Hospital in Madison. Wards by day. Everything else on this map happens after sign-out. The road here ran through research stints at Mayo Clinic and UPMC.
Research assistant
My alma mater in Riyadh and still my research home. Clinical outcomes work, mostly gastroenterology, with collaborators across Saudi Arabia and the United States.
Chief of staff
Healthcare M&A and growth advisory. I run the operating side of the practice: process, systems, and follow-through, so the principals stay on the deals.
Chief of staff
A fund at the meeting point of decentralized infrastructure and AI. I handle LP relations and fund operations, and I build the automation that runs both.
Chief of staff
A merchant bank for the intelligence buildout: land, power, silicon, and capital, advised as one market. I keep the machinery behind it running.
Founder
An AI examiner for clinical skills exams. Medical students run standardized-patient encounters against voice AI and get scored the way the real exam scores them, on a rubric.
Publications
Peer-reviewed work in gastroenterology, cardiology, and surgery, pulled onto this page straight from PubMed. The shelf in the library holds every one of them.
In the lab · three builds
Retained food on EGD. Computer vision that flags retained food during upper endoscopy, so the call gets made consistently, not by mood.
A microbiome screen for IBD. Machine learning over stool metagenomes to detect inflammatory bowel disease. It holds up on cohorts it never saw.
GI trial simulator. An open R package that re-runs the sample-size math behind published GI trials and reports which numbers survive.
A fourth bench is under a sheet.

A model that flags retained food during upper endoscopy. Gastric contents change the read, the aspiration risk, and the repeat-scope decision, so the call should be made consistently, not by mood.
