My research at the Environmental Fluid Mechanics lab has centered on the transport of water vapor, CO2, and temperature in natural and urban environments. My previous projects focused on improving flux quantification, including novel methods to partition total ecosystem fluxes of CO2 and water vapor into ground and plant contributions, as well as on investigating flux parameterization methods based on the Monin-Obukhov Similarity theory. As a postdoctoral researcher I investigate physical processes within urban canopy models with the goal of improving parameterization for more accurate weather prediction in cities. My research interests include land-atmosphere interactions and atmospheric turbulence, urban microclimate and hydrometeorology, as well as urban resilience and sustainability. In addition to field measurements, my work incorporates numerical simulations across different scales utilizing large-eddy simulations and weather prediction models.
