Research Interests:

My research interests fall into the areas of atmospheric radiative transfer, satellite remote sensing, and high performance computing. Currently I am working on the World Meteorological Organization’s radiative forcing model intercomparison project (RFMIP) to quantify the impact of radiative parameterization error on the instantaneous radiative effect of aerosol on the modeled climate. I do this by comparing aerosol IRE from a climate model to aerosol IRE from a global, line-by-line radiative transfer model framework I developed. You can read more about that in the GRL paper from 2017.

During my PhD work I developed a 3D, broadband, Monte Carlo Radiative Transfer Model, called MCBRaT3D, to represent high spatial and spectral resolution simulations of solar and thermal radiation transport in earth’s atmosphere. If you’re interested in using this model, or a monochromatic version of it,  or aiding in either model’s development visit my page on GitHub.

During my Master’s project I utilized NASA datasets from the MISR, MODIS, and ASTER instruments on board the Terra satellite platform. I developed a pattern recognition algorithm to correct over estimations of regional cloud fraction due to low-spatial-resolution effects. That algorithm is now part of the regular processing of the data products for the MISR instrument. You can read more about that in the JGR paper describing the technique.

High performance computing is the thread that ties all of these things together. Cutting edge computing resources enable cutting edge science and in-turn cutting edge science informs the design of future computing resources. I’m passionate about advocating for high performance computing and big-data management throughout my career as it has the potential to advance scientific understanding immensely.
