About Me

I’m a researcher engineer!

Designing HVAC and Energy Exchangers with a Focus on Cold Climates

I am a mechanical engineer and PhD candidate at the University of Saskatchewan, working at the intersection of heat and mass transfer, HVAC, and energy efficiency in buildings.

My research focuses on improving the performance and frost resistance of liquid-to-air membrane energy exchangers (LAMEEs) for cold-climate applications.

I combine experimental work, modelling, and data-driven analysis to develop practical solutions for industry.

Research Focus

My interests are broad, but the focus is on:

Frost

Frost-resilient liquid-to-air membrane energy exchangers (LAMEEs)

Investigating frost limits, membrane properties, and operating strategies under subzero conditions.

Transfer Phenomena

Heat and mass transfer in complex geometries

Experimentation, theoretical modeling, and CFD analysis in compact heat exchangers, e.g. cross-flow and heat wheels, liquid-to-air energy exchangers, condensers, and air mixers.

HVAC

Energy efficiency in buildings and HVAC systems

Applying exchanger and system-level analysis to reduce energy use and improve indoor environmental quality.
