Senior🎓
Top SchoolMichael Rushanan is Chief Scientist at Harbor Labs with 14+ years of experience specializing in medical device security, secure product development frameworks, and penetration testing across hardware, firmware, and cryptosystems. He holds a Ph.D. and two master’s degrees from Johns Hopkins, where he published cryptanalysis, medical-device security, and applied-cryptography work and contributed to notable open-source projects like Charm. At Harbor Labs he has led cybersecurity programs for over 90 devices spanning infusion pumps, ICDs, surgical robotics, EHRs, and DNA sequencers across global regulatory pathways (De Novo, 510(k), PMA). A pragmatic researcher-turned-practitioner, he pairs deep academic rigor with hands-on reverse engineering, cryptanalysis, and secure-coding leadership to shape risk assessments, threat models, and regulatory-compliant testing. He also teaches at JHU, serves on UMBC’s advisory board, provides pro bono security support, and automates developer tooling—evident from his Windows installer and build automation work on the Charm cryptosystem framework. Outside work he obsessively tinkers with home labs, cloud free tiers, open-source contributions, and anything mechanical, bringing a hacker’s curiosity to institutional-scale security challenges.
