Current State

As of July 2007, I am a post-doctoral researcher in Department of Atmospheric and Oceanic Sciences at UCLA, where I work in Bjorn Stevens' research group. Although affiliated with UCLA, my work is under the auspices of the Center for Multiscale Modeling of Atmospheric Processes (CMMAP), based in Fort Collins, Colorado, where I am also based. My research focuses on isolating and understanding low-cloud effects on climate using numerical models. Read more at research.brian.

Past States

While at UC Berkeley, I worked with Rich Muller's Astrogeophysics group and studied paleoclimate. During that time I worked primarily on two topics. First, I did analysis of high frequency climate oscillations. This work was presented to the Institute of Nuclear and Particle Astrophysics in 1999. It was also presented at the Fall 1999 meeting of the AGU [webarchive][htmlarchive]. The second project was the construction of a time series called the Benthic Stack, which was published in Paleoceanography in 2002. Prior to that, we presented it at the Fall 2000 meeting of the AGU [webarchive][htmlarchive].

My first project in graduate school was an investigation of the processes that control the mean depth of the planetary boundary layer. I analyzed output from the UCLA GCM and a simple mixed layer mass budget analysis to understand the land-sea contrast in PBL depth, including a simple analytical model of the diurnal cycle of the convective (dry) mixed layer. This work was supervised by Alex Hall and Bjorn Stevens, and the paper can be downloaded in the Publications section.
