Bio
I work at the intersection of climate resilience and climate solutions to enhance the life-sustainment and security of our planet. I invest in climate tech startups, and advise on climate and nature risk for the financial and other sectors.
I am an ocean, weather and climate scientist experienced in fieldwork, AI/ML, and earth system models for predicting future patterns. My background is in nonlinear dynamics and complex systems.
I was on the founding team of a VC fund for ocean climate tech, and led early product development of extreme event perils at a climate risk startup after leaving an engineering professorship.

Dr. Julie Pullen was a founding Partner and Chief Scientist at VC fund Propeller Ventures, investing in early-stage companies and leading initiatives with ocean and climate research institutions to advance pioneering science and technology to solve the climate crisis. Dr. Pullen was the Climate Strategist (previously Director of Product) at Jupiter Intelligence, a start-up delivering climate risk analytics using AI/ML and cloud computing, and was an adjunct research scientist at Columbia’s Climate School. She was previously Associate Professor in Civil, Environmental, and Ocean Engineering at Stevens Institute of Technology where she organized field studies globally to improve our understanding and prediction of the Earth system. She is a Fellow of the Explorers Club for her fieldwork on tropical extreme weather and marine aerosol-cloud interactions, and is a past science fellow at Stanford’s Center for International Security and Cooperation.
Dr. Pullen's scientific expertise spans climate, weather and water with a focus on coastal flooding, heatwaves and drought and their impacts. Dr. Pullen’s research has contributed to the understanding and development of resilience and adaptation in coastal environments and the enhancement of Earth System Models on weather and climate timescales.
She was earlier Director of the DHS-funded National Center for Maritime Security where she created programs in environmental and nuclear security and led applied research projects and commercialization of ocean and atmosphere tech across government labs, universities, the Coast Guard, and Customs and Border Protection. Her research has improved the fidelity of airborne chemical/biological/radiological/nuclear (CBRN) transport and dispersion models, particularly in coastal and urban areas. At the Naval Research Laboratory, she pioneered the coupling of high-resolution models of the ocean and atmosphere for operational prediction globally and improved air/sea ensemble prediction.
Dr. Pullen was elected to the Council and Executive Committee (2019-2022) of the American Meteorological Society (AMS) and was previously the elected physical oceanography Councilor for The Oceanography Society (2015-2018). Dr. Pullen peer-reviewed the Fourth and Fifth National Climate Assessment (NCA4, NCA5) and served on National Academy of Sciences committees on Earth System Prediction (2014-2016) and Sustaining Ocean Observations (2020). She was a chapter co-author of the 2015 New York City Panel on Climate Change (NPCC2) report. She is currently a member of the U.S. Climate Security Roundtable.
She has taught graduate-level Dynamic Meteorology, Fluid Dynamics, and Oceanography and originated new graduate courses in Nuclear Security and also Tropical Meteorology as a Fulbright Visiting professor at the University of the Philippines (2018). She has advised and graduated master’s and Ph.D. students who work in academia, weather services, data science and renewable energy.
Dr. Pullen holds a Ph.D. in physical oceanography from Oregon State University and a master’s degree in applied mathematics/nonlinear dynamics from the University of Arizona. She majored in physics and math at Macalester College. The first undergraduate intern at the Santa Fe Institute, she later worked at the Center for Nonlinear Studies at Los Alamos National Laboratory.
