Nucleation Team

Valerie Gardner, Managing Partner

For much of the last decade, as a principal of Tiemann Investment Advisors, LLC (TIA), Valerie has been studying the impacts of carbon risks on economic activity and portfolio returns. Beginning in 2009, she began developing quantitative, data-driven strategies for reducing carbon risks within investment portfolios. While many of her peers were engaging in ESG-focused explorations, Valerie’s research led her in an entirely different direction: seeking to understand where the most scaleable sources of abundant clean energy come from. This caused her to take a deep dive into the nuclear industry, when she discovered that the vast majority of the U.S.’s carbon-free energy is produced by nuclear power. TIA introduced its “Future Generation” portfolio in 2014, utilizing a unique methodology for constructing a “post-carbon priced” portfolio for public market securities, that effectively eliminates carbon risk without reducing market exposure within the overall energy sector allocation. In developing the Future Generation portfolio, what Valerie learned about nuclear power—and especially the advancements being developed now—led to the launch of Nucleation Capital.  TIA, an investment firm founded by Ms. Gardner and Dr. Jonathan Tiemann in 2002, with over $250 million in AUM, sponsored the development of Nucleation Capital.

Prior to TIA, Valerie served as co-founder, CFO and General Counsel of two innovative, high technology companies, Willow Peripherals in New York City and WebTV Networks in Silicon Valley, which was acquired by Microsoft. WebTV got Valerie hooked on surfing the Internet which led her to learning about climate change. In 2005, she embarked upon an more active period of research and learning about key environmental issues through courses and lectures at Stanford, UC Berkeley and NASA Ames. It quickly became clear that energy use and, in particular, burning fossil fuels to generate power, was the primary cause of climate change. Valerie organized a community solar purchase program in 2008 and installed 50 panels on her own home’s roof. When these barely met her home’s energy usage, she collaborated on the development of a home energy efficiency program that qualified for Federal Stimulus funding and was shared with five Silicon Valley towns. Despite her efforts, energy usage continued to grow in each community. After recognizing that, merely by using nuclear power combined with solar and wind—rather than gas—people could use as much energy as they needed without adding emissions, Valerie set about to learn more about nuclear energy. In 2016, she co-founded the Climate Coalition, to share knowledge about nuclear and to advocate for inclusive Clean Energy Standards focused on emissions, rather than the discriminatory Renewable Portfolio Standards, that excluded clean nuclear power and instead embraced dirty natural gas. Climate Coalition seeks to build unity among climate activists for prioritizing the achievement of zero-emission grids over continued bickering about choice of technology. 

Valerie earned a BA from Colgate University, a JD from Northeastern University Law School and an MBA from the Yale School of Management.  She earned her Private Pilot license at age 18 and in college was a co-founder of “Earth House,” an off-campus residence focused on environmental-minded living. She founded GHREEN (the Gideon Hausner Recycling and Environmental Education Network) in 2005, helped launch the Atherton Environmental Programs Committee in 2006, which she led through to 2018, and is a current member of the Yale Blue Green Alumni Sustainabilty Committee.

Rodney Adams, Managing Partner

Rod Adams is an independent atomic energy expert who has chronicled the nuclear industry over the last 25 years. He has a B.S. in English from United States Naval Academy (USNA), a M.S. in Systems Technology from U.S. Naval Postgraduate School, and a Naval War College diploma in Defense and Strategic Studies. His sea-going submarine service included 11 deployments, five as a junior officer on USS Stonewall Jackson in various engineering and communications division assignments, and six as the Engineer Officer (Engineering Department Head) on USS Von Steuben. During a shore duty assignment at the USNA, he pursued an independent studies program focused on alternative energy technology. He focused on refinements to nuclear heated, closed cycle gas turbine engines and received a patent for a related control system. He resigned his active duty commission to start Adams Atomic Engines. AAE was founded on the idea that much smaller nuclear plants using simplified system designs could be competitive power source for commercial ships, islands and populated or resource-rich areas not served by conventional power grids.

In the post-911 era, Rod was recalled to active duty as a Systems Engineering instructor at the USNA. He closed Adams Atomic Engines—which was ahead of its time—and served as a program manager for a headquarters information portal and as a requirements officer for numerous programs including submarine and surface ship technical training and shore-based and nuclear shipyard maintenance facilities. Ultimately, Rod retired from the US Navy as a Commander. Mr. Adams is a recognized thought leader in the small nuclear power system sector. He has published articles in Forbes, ANS Nuclear Cafe, and Fuel Cycle Week. He started publishing insightful information about nuclear power back in 1995, which over the years became the online newsletter, Atomic Insights, now one of the most respected blogs focused on nuclear energy. In 2006, Rod again broke new ground by adding live interviews, making The Atomic Show the only place to learn about key trends from industry experts—podcasting before that was a thing. Both venues continue to be the place where Rod makes atomic energy information accessible to the public.

Jonathan Tiemann, Partner & CFO

Dr. Jonathan Tiemann, co-founder of Tiemann Investment Advisors, LLC, has over 30 years of investment experience, including 18 years as President and Chief Investment Officer of Tiemann Investment Advisors. He earned his B.S. in Applied Mathematics from Yale, his M.S. in Operations Research, and his Ph.D. in Finance from Yale. Jonathan was an Assistant Professor of Finance at Harvard Business School for five years before joining Wells Fargo Nikko Investment Advisors (which later became Barclays Global Investors (BGI), and is now Blackrock). Over five years, he served in a number of roles, ending up as Chief Investment Strategist, responsible for managing $200 billion in institutional assets. After BGI, he served as President of BARRA RogersCasey Asset Services, where he developed a hedge fund-based investment strategy for institutional investors.

Dr. TIemann was at the forefront of what is now called “Fintech” and developed the AdvisorTech investment strategy while serving as Chief Investment Officer and Chief Investment Strategist at AdvisorTech Corporation and later for the MyVest Corporation. He has served as an expert witness for financial litigation and has consulted on numerous investment and valuation due diligence teams. He has also served on the Economic Advisory Board of the Financial Industry Regulatory Authority (FINRA). Jonathan collaborated in the development of Future Generation’s index-style approach to reducing risks posed by carbon emissions on client portfolios. This innovative approach helps ensure that all portfolios have a more appropriately diversified energy sector portfolio that more fully reflects the growing contributions of clean energy sources, something few other “sustainable” or ESG portfolios can claim.
