Matt Günhan Ertosun, PhD
2x Founder | Co-founder @ SUN (a16z Speedrun SR006) | Stanford Eng. PhD | Former Venture Builder @ $2.5B VC | AI & Generative AI | Scientist | Inventor | Author | Meditation Enthusiast Entrepreneur, AI technologist, and Stanford-trained scientist (more than 400 scientific citations and multiple patents) working at the intersection of artificial intelligence, startups, and product innovation. Previously worked as a venture builder at a $2.5B venture capital fund, where I helped incubate and prototype multiple AI and frontier-technology startups: leading technical development from idea → prototype → MVP. Earlier in my career I led AI and data science initiatives in finance, healthcare and medical imaging, building AI & machine learning systems for next-generation technologies. My technical work spans: • Generative AI (LLMs, diffusion models, multimodal systems) • Machine learning, deep learning & data science • AI product development & startup incubation • Medical imaging and healthcare AI • Advanced modeling, simulation, and statistical learning Prior roles include Principal Scientist (AI/Data Science) at medical imaging companies and founding an AI healthcare startup applying deep learning to radiology. I received my PhD in Electrical Engineering from Stanford University, where my research focused on advanced device physics, modeling, and emerging technologies. My postdoc at Stanford School of Medicine involved applications of machine learning, AI and data science to medical domain. Later, I was a research fellow at Stanford School of Medicine at Stanford Cancer Imaging Training (SCIT) Program, supported by the National Cancer Institute, with my research focussed on applications of deep learning to medical imaging. Fun fact: I had published three papers at international prestigious journals while I was still an undergraduate student. I am also an author and researcher interested in the intersection of technology, philosophy, and human knowledge.
