About

I'm a researcher working at the intersection of atmospheric science, polar climatology, and observational methods. My work focuses on understanding the complex energy exchanges that occur at the surface-atmosphere boundary in extreme cold environments, particularly in Greenland and the Arctic.

My research draws on a combination of field measurements, remote sensing, and computational modeling to investigate how turbulent fluxes, radiation, and boundary layer dynamics interact over ice sheets and snow-covered terrain. I've spent multiple field seasons deploying and maintaining instrumentation towers on the Greenland Ice Sheet, collecting high-frequency eddy covariance data alongside standard meteorological observations.

Research

Surface energy balance over ice sheets and glaciers remains one of the more challenging problems in geophysics. The stable boundary layers that develop over cold surfaces violate many of the assumptions embedded in standard flux-profile relationships, requiring careful attention to measurement technique and analytical methods. I'm particularly interested in how intermittent turbulence events transport heat and moisture in these environments, and what that means for melt processes at larger scales.

Beyond the immediate physics, I'm drawn to questions about how we observe and quantify environmental change. Instrument siting, data quality control, gap-filling strategies, and the propagation of uncertainty through derived quantities all shape what we can claim to know about the climate system. I try to take these issues seriously in my own work and contribute to community discussions about best practices in observational science.

Current projects include the development of improved quality control algorithms for eddy covariance measurements over snow and ice, analysis of long-term trends in the surface energy budget at multiple Greenland sites, and remote sensing retrievals of surface properties from satellite platforms. Collaboration is central to this work, and I'm fortunate to work with teams spanning glaciology, remote sensing, and atmospheric modeling.

Photography

Field work in remote environments inevitably cultivates a photographic practice. I carry a camera into the field and have developed a body of documentary and landscape work over the years. The photographs serve partly as scientific documentation, partly as a personal record of time spent in extraordinary places, and partly as an attempt to communicate something about these environments that numbers alone cannot convey.

I'm interested in the aesthetics of scientific instrumentation, the visual textures of ice and snow at various scales, and the strange beauty of infrastructure in otherwise empty landscapes. See the work โ†’
