Billerica, MA — June 3, 2025 — Nirrin Technologies, a developer of analytical tools poised to transform bioprocess analysis, today announced that its founder and Chief Technology Officer, Bryan Hassell, Ph.D., has been appointed Chief Executive Officer.
Since founding Nirrin Technologies, Dr. Hassell has led the development of its High-Precision Tunable Laser Spectroscopy (HPTLS) platform and the launch of Atlas, establishing Nirrin as a leading process analytical company for complex biologics and advanced therapies. As CEO, he will now guide the company’s strategic growth and innovation as it expands its impact on advanced manufacturing and real-time process control.
“Bryan has not only led the development of Nirrin’s core technology, but also helped build a culture of scientific rigor and customer focus that defines who we are,” said Steve Battista, COO. “His deep understanding of the technical challenges in bioprocessing, combined with his vision for how analytics can transform the industry, makes him uniquely suited to lead the company forward.
Prior to Nirrin, Bryan served as a Principal Investigator for the U.S. Department of Defense (DOD), evaluating the innovation potential of small businesses to help address national security challenges and ensure technological superiority for the U.S. Navy and U.S. Special Ops Command. He held a role as an Investment Associate with Anzu Partners, a venture capital/PE firm concentrating on industrial breakthrough technologies, leading diligence on investments into their industrial and life science portfolio companies. Bryan received a Ph.D. in Applied Physics from Harvard University where he developed an organ-on-a-chip microfluidic model of EGFR non-small cell lung cancer to explore tyrosine kinase inhibitor resistance and signaling dynamics in vitro. This work led a $80M DARPA grant and launch of Emulate Bio (valued over $1B and on the Deloitte Technology Fast 500™ list).
“I’m honored to step into the CEO role at a time when the need for smarter, more reliable process analytics has never been greater,” said Bryan. Everything we have accomplished to date is a reflection of the talent and dedication of our team—scientists, engineers, and advisors who’ve been instrumental at every step. I’m energized by the momentum we’ve built and look forward to expanding our reach as we help more customers drive greater consistency, efficiency, and quality across their bioprocessing workflows.”
