Our products are designed to support decision-making, understanding water-related climate risks, detailing economic impacts associated with climate risk, and visualization of potential solutions.

Meet The Team


Lydia Bleifuss

Research Analyst

Lydia strives to bridge gaps between climate risk and climate action at scale. Shaped by her passion for moving water and watershed systems, Lydia is dedicated to grounding western conservation in modern data analyses and adaptive management tools. Lydia holds a Bachelor of Arts degree from Lewis & Clark College targeted toward river development policy and corresponding social inequities, and a Masters of Environmental Science and Management from University of California Santa Barbara as a Sustainable Water Markets fellow specialized in water resources management and analysis. Before joining Virga Labs, Lydia worked with Trout Unlimited to support watershed restoration and climate resilience through engagement with agricultural communities and agency partners. When not mind-melding with the Virga Labs team, Lydia makes time for morale boosting activities such as scrambling around creek beds and tide pools or sewing accidentally asymmetric clothing.
