About Me
I am a Research Scientist III in the Department of Atmospheric Science at Colorado State University.
My research interests include ocean-atmosphere coupled processes and their effects on the intensity, frequency, and organization of tropical convection.
I'm especially interested in understanding how these interactions and their temporal and spatial scales affect the 30-70 day Madden-Julian oscillation (MJO) and its predictability.
The MJO is a fascinating disturbance that affects global weather phenomena, including drought, floods, severe storms, sea ice concentrations, and the El Nino-Southern Oscillation (you can watch a short video on the subject here).
Understanding and simulating the MJO has frustrated, challenged, inspired, and delighted scientists since its discovery in the early 1970s.
To investigate ocean-atmosphere interactions within the MJO, I analyze observations and perform model experiments using global and regional models.
At CSU, I work with Professors David Randall, Peter Jan van Leeuwen, Eric Maloney, and Sue van den Heever.
I'm a regular participant in our department's weekly Large Scale Dynamics "Super Group" meeting, a lively and informative gathering of the research groups of Professors
Elizabeth Barnes, Eric Maloney, David Randall, Dave Thompson, Jim Hurrell, and Maria Rugenstein.
More recently, I've become involved with our department's NSF Research Experience for Undergraduates program.
I've mentored students and now co-direct the program with Dr. Melissa Burt.
