Appleton, Wisconsin, United States
Summary
👤
Senior🎓
Top SchoolPaul Gessler is a building controls research engineer with 12 years of experience applying model-based design and control software development to HVAC and building automation systems. Currently at Pacific Northwest National Laboratory, he blends systems thinking with hands-on commissioning, embedded controls, and MATLAB/Simulink test workflows to improve energy efficiency and occupant health. His background spans industry and academia—from Johnson Controls chiller control algorithms and automated testing to teaching modeling and numerical analysis—giving him a rare mix of practical product development and pedagogy. He is motivated by creating affordable, healthy built environments that lower energy use without worsening climate change, and he often approaches problems by connecting control logic to occupant outcomes. Not obvious from titles alone: he has a strong history of rapid prototyping and hardware-in-the-loop validation, enabling solutions that move cleanly from simulation to deployed systems. Based in Appleton, WI, Paul combines engineering rigor with a customer-focused technical support mindset to deliver measurable operational improvements.
