The PATCH Research Fellow position offers an opportunity for experienced professionals from government, industry, or academia to join a mission-driven team advancing healthcare cybersecurity. The PATCH Research Fellow helps build Whole-Hospital Simulations, realistic testbeds that emulate complex healthcare environments, and Vulnerability Mitigation Platforms that safeguard both clinical and non-clinical networks. This work will directly impact patient safety and digital resilience in some of the most vulnerable healthcare settings. Success in this role will help revolutionize the healthcare penetration testing marketplace by shifting the focus from compliance-based checklists to understanding how gracefully a hospital system fails and recovers under attack. The platforms are also expected to drive a paradigm shift in medical device security regulation, moving evaluation away from individual components and toward system-level thinking across vast networks of interacting medical devices. The role focuses on applied research and experimentation with these platforms to improve the resilience and security of medical devices, hospital networks, and healthcare delivery systems. PATCH Research Fellows will bring their expertise to guide technical research, mentor students, and collaborate with faculty and industry partners on advancing the state of practice in healthcare cybersecurity. This position is 100% externally funded and will be considered for reappointment on an annual basis based on the continued availability of funding. Appointments may last from several months up to one year, with the possibility of renewal based on mutual interest and performance.
