Quantum Leap Energy Appoints Dr. Peter Fiske to Strategic Advisory Board

Technology Commercialization Leader Expected to Enhance QLE's Government Partnerships and Advanced Materials Strategy

DALLAS, May 06, 2026 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. (NASDAQ: ASPI) (“ASPI”) today announced that Quantum Leap Energy LLC (“QLE” or the “Company”), a wholly-owned subsidiary of ASPI dedicated to advancing innovative technologies and processes across critical segments of the fission and fusion nuclear fuel cycle, has appointed Dr. Peter S. Fiske to QLE’s Strategic Advisory Board (SAB).

“QLE is intentionally building the leadership, advisory depth, and execution discipline required to scale throughout government and commercial nuclear energy markets,” said Dr. Ryno Pretorius, Chief Executive Officer of QLE. “Dr. Fiske brings firsthand experience from the highest levels of government engagement and technology commercialization. His perspectives will directly inform how we prioritize, engage, and execute as demand accelerates for trusted, innovative solutions supporting U.S. and allied clean energy missions.”

Dr. Fiske brings extensive experience in technology commercialization, advanced materials development, and strategic partnerships with government agencies and institutional customers. He was the founding Executive Director of the National Alliance for Water Innovation (NAWI), the U.S. Department of Energy's 5-year, $110M Energy-Water Innovation Hub at Lawrence Berkeley National Laboratory. In this role, he oversaw early-stage applied research focused on dramatically lowering the cost and energy requirements of water treatment and reuse through modular, scalable designs.

“I've spent my career working at the intersection of innovation, policy, and complex technical challenges,” said Dr. Fiske. “QLE is operating in a space where trusted technology and credibility matter. I look forward to contributing decades of experience as the Company expands its presence supporting government and commercial decision-making with advanced nuclear fuel solutions.”

The appointment comes at a pivotal moment as QLE accelerates its organizational development and strategic initiatives, following the recent formation of its Strategic Advisory Board, the appointment of Dr. Nate Salpeter as Chief Technology Officer, and the announcement of a strategic collaboration with the University of Bristol for the design of a state-of-the-art lithium laser research facility in the UK. Dr. Fiske's addition to the SAB underscores QLE's growing momentum as governments and energy sector partners increasingly rely on advanced nuclear fuel technologies to support clean energy goals, energy security, and mission-critical infrastructure.

About Dr. Peter S. Fiske

During his career, Dr. Fiske has served as a trusted advisor on a wide range of high-profile technology commercialization initiatives, including matters involving energy, advanced materials, and government funding. Previously, he served as Chief Executive Officer of PAX Water Technologies, Inc., where he pioneered the use of biomimicry to develop innovative, energy-efficient technologies for municipal water systems. He also co-founded RAPT Industries, Inc., a pioneer in plasma processing of optics and semiconductors, successfully licensing technology to major semiconductor equipment manufacturers and leading the company's first product sales.

Dr. Fiske led a research team at Lawrence Livermore National Laboratory with applications to materials science and energy storage, and served as a White House Fellow, working as Special Assistant to the Secretary of Defense for Special Projects where he led a major personnel policy reform initiative for the Pentagon. He holds a Ph.D. in Geological and Environmental Sciences from Stanford University and an M.B.A. from the Haas School of Business at the University of California, Berkeley. He is also a founding faculty member of the Department of Energy's I-Corps Program and has been widely recognized for his strategic insight and leadership in technology entrepreneurship.

Dr. Fiske's established network within defense contracting, government procurement, and energy sector partnerships positions him to identify critical funding opportunities through SBIR/STTR programs, Department of Energy initiatives, and Defense Innovation Unit collaborations, while his proven track record in government relations provides critical capabilities for building sustainable revenue pipelines with institutional customers.
