Summary
👤
Senior🎓
Top SchoolRobert Calhoun is a Principal Engineer and co-founder of SoundThinking (formerly ShotSpotter) with over two decades of experience building real-time acoustic detection and location systems for public safety. He leads the Detection Team responsible for both backend source-location and AI/ML classification algorithms as well as embedded Linux sensor software, blending signal processing, numerical optimization, and secure IoT engineering. Holder of eight U.S. patents—seven in gunshot detection—and trained as a materials scientist (PhD, MIT), he brings uncommon cross-domain expertise from magnetic materials and electroplating to modern distributed systems. A practical proponent of AWS managed services for secure, scalable architectures, he also contributes kernel and Yocto layers publicly on GitHub that reflect hands-on embedded systems work. Based in Oberlin, Ohio, he balances deep research rigor with startup product focus and occasional surprising impact in adjacent fields (his electroplating patent influenced semiconductor Damascene processes).
