Tyler joined PNNL in 2021 as a Senior Associate Building Energy Efficiency Engineer. He is an architect and engineer with interests in fault detection and characterization of building systems. He holds a Bachelor of Science in Mechanical Engineering from Florida State University and a Master of Science in Architecture from Georgia Tech. Before joining PNNL, Tyler spent two years at Oak Ridge National Laboratory (ORNL) where he developed numerous high-impact simulation and decision-making tools to aid with building envelope design and assessment. While his research focuses on building components, Tyler's main interests relate to people and their access to equitable, healthy, and energy-efficient buildings.
