Allison Mahvi

Postdoctoral Researcher-Mechanical Engineering

Orcid ID

Allison joined NREL's Building Energy Science Group in 2019 as a postdoctoral researcher. Her research focuses on characterizing thermal energy storage materials and integrating them into building energy systems.

Allison has extensive experience in experimentally and computationally evaluating novel heat transfer components for energy systems. Prior to joining NREL, Allison was a postdoctoral scholar at the University of Illinois at Urbana–Champaign, where she worked on developing nano and microscale surface coatings to enhance refrigerant condensation and evaporation. Additionally, she completed her Ph.D. at Georgia Tech, where she characterized two-phase flow distribution in microchannel heat exchanger manifolds and developed new heat transfer enhancement devices for power plant air-cooled condensers.
