Summary
👤
Senior🎓
Top SchoolJack Dunn is a co-founder and technology leader with 12 years of experience at the intersection of optimization, machine learning, and practical software engineering. He earned a PhD in Operations Research from MIT under Dimitris Bertsimas and translates cutting-edge optimization research—like optimal decision trees and robust classification—into production-ready, interpretable AI solutions. As Co-Founder of Interpretable AI and CTO at Ground Truth Analytics, he balances research rigor with product delivery, having previously led development of OpenSolver (230k+ downloads) and contributed to core Julia optimization tooling such as JuMP and Yggdrasil build automation. His hands-on background spans solver integration, build/release engineering, and mixed-integer optimization applied in industry and at Google internships, demonstrating both systems and algorithmic depth. Based in Cambridge, MA, he combines academic honors with a track record of shipping widely adopted open-source tools that make advanced optimization accessible to non-experts.
