Duncan Brandt

I’m a Senior AI Engineer with 10+ years of experience architecting and deploying machine learning and generative AI solutions across healthcare, video analytics, and enterprise IT. I’ve led LLM integration at virtual care platforms, and I’m driven by turning research results into production systems that measurably improve outcomes.

At Curai Health, I led a transition from traditional NLP to GPT-3/GPT-4 powered conversational features for a chat-first virtual primary care platform. I designed a multi-stage LLM pipeline for automatic SOAP note generation, reducing physician documentation time by 35%, and I co-created the DERA framework to improve clinical summary quality and care plan generation.

I’ve also built robust ML foundations for real-world impact—creating FHIR R4-compliant EHR data layers, developing knowledge injection techniques to reduce hallucinations in after-visit care instructions, and mentoring 5 junior AI engineers and interns. Earlier, I engineered deep learning video pipelines with YOLO/Faster R-CNN (92% detection accuracy) and deployed BERT-based semantic search to reduce evidence retrieval time from hours to minutes.
