Josh Quinnell, Ph.D.

Senior Research Engineer

Dr. Josh Quinnell is a Senior Research Engineer at the Center for Energy and Environment. Josh has thirteen years research experience in solar energy, heat and mass transfer, and energy efficiency. Currently Josh is working on grid modernization efforts including strategic electrification, solar energy deployment optimization, and using efficiency and other DERs to manage distribution system capacity. Josh’s recent work includes HVAC duct leakage & retrofit sealing, condensing boiler efficiency, energy recovery ventilation (ERV) systems, garage contaminant transport, and residential furnace efficiency retrofits.

Prior to CEE Josh spent time researching thermochemical storage cycles at ZAE Bayern outside Munich Germany and the Solar Energy Lab at the University of Minnesota. Josh obtained his Master’s degree (2008) and PhD (2012) in Mechanical Engineering from the University of Minnesota.
