The Lenert Lab at the University of Michigan Department of Chemical Engineering was established in 2016 to study new approaches for control of energy transport, with the primary goal of enabling greater integration of renewables. Our research focuses on the development of novel, highly efficient thermophotovoltaics for grid-scale energy storage, passive radiative cooling materials for energy efficiency, next-generation solar thermal technologies, microfabricated devices for near-field sensing, and high-temperature stable, catalytically active materials.
Our research has been supported by the US Department of Energy, DARPA, US National Science Foundation, General Motors, Michigan Economic Development Corporation, 3M Foundation, Antora Energy, UM MCubed program, Graham Sustainability Institute, UM Lurie Nanofabrication Facility, Rackham Graduate School, UM Center for Entrepreneurship, and the UM Center for Socially Engaged Design.
The group is led by Dr. Andrej Lenert, an associate professor of ChE at UM. It includes postdoctoral fellows and doctoral, masters, and undergraduate students from UM ChE and other departments/institutions. For inquiries, please email alenert@umich.edu.
