Work Experience
Lead Applied AI Scientist
harrison.ai
- Led the machine learning (ML) team that delivered a state-of-the-art, novel chest X-ray deep learning model to hospitals around the globe.
- Made core contributions along the entire machine learning stack from data labeling, pre-processing, migration, anonymization, training, experimentation, and deployment.
- Hired and trained team members and led projects from ideation to successful product delivery.
- Published clinical and ML research in top-tier medical journals such as Lancet Digital Health.
Senior Data Scientist
Sypht
- Founded a team for a commercialized and productions machine learning API platform, initially as the sole machine learning expert on the team.
- Oversaw both machine learning stack—CV and NLP deep learning models, and traditional ML—and end-to-end productionization, including automated testing, API endpoint management, and efficiency.
- Helped grow and scale the team from 5-15 members and the product from zero to over two million paid requests per month; helped secure funding of several million dollars.
Data Scientist
BCG Digital Ventures
- Developed and scaled machine learning startups for large commercial partners.
- Collaborated with the leadership team to coordinate hiring and growth of the machine learning team.
- Received the highest band in the annual performance review as one of only 5% of employees globally.
Experience
Annalise Enterprise CXR
https://annalise.ai/solutions/annalise-cxr/I helped develop our initial machine learning (ML) models and led our latest release's continued iteration and deployment. I iterated upon our ML strategy, ran and documented extensive experimentation using state-of-the-art and novel techniques, liaised with product and clinical leads, and deployed and tested our healthcare AI in production.
