Summary
Rohan Bhandari is a staff machine learning engineer in San Francisco with 11 years of experience building production ML and NLP systems, currently focused on healthcare at Included Health after leading data science at GYANT. He built GYANT’s data team and core conversational AI platform—engineering an NLP system that understood over 2,000 intents and materially improved a symptom checker’s accuracy while scaling condition coverage. His background spans experimental particle physics at CERN, where he handled petabyte-scale data and demonstrated deep learning gains for detectors, to fast-moving product work shipping end-to-end ML services and ETL pipelines. Rohan blends research rigor from a PhD in experimental high-energy physics with hands-on product delivery, mentoring junior scientists and advising PhD-to-industry transitions. A pragmatic leader who routinely reduces operational costs (e.g., automating invoicing to cut costs by 98%), he’s comfortable from model architecture down to data infrastructure and cross-functional strategy.
