I am a programming scientist at GFDL’s Weather and Climate Dynamics group.  I am employed through Engility and work with the FV3 Dynamical Core group.  Over the past two years I have been a part of the High Impact Weather Prediction Project (HIWPP) and the Next Generation Global Prediction System (NGGPS) project.  I do model data pre- and post-processing and compare forecasts to other model forecasts, reanalysis datasets, and observations (NCEP Reanalysis, ERA-Interim, Prepbufr, NCEP Stage IV precip, satellites, etc.).  I create presentation graphics and animations, co-manage the FV3 webpage, and will act as a team liaison for the next phase of NGGPS.

*If anyone at GFDL has ArcGIS questions, I am the person to ask.

 

Education

In August 2014 I graduated from University of Hawaii at Manoa with my M.S. in Meteorology.  My adviser was Dr. Michael Bell and my thesis research focused on estimating supergradient winds (SGW) in the primary and secondary eyewalls of Hurricane Rita (2005).  SGW are suspected by some to be associated with hurricane intensification.  Using both a WRF simulation and real airborne observations from Rita (synthesized using SAMURAI) I investigated the evolution of SGW, during an eyewall replacement cycle.  I found SGW estimates that are comparable in magnitude to other similar studies.  To find out how accurate this estimate was, I took synthetic observation of the WRF model output and compared this to the actual model output fields. Using SAMURAI, I was able to achieve low errors for wind retrievals, though pressure gradient errors were less impressive.  This research is ongoing.

In May 2012 I graduated from University of Delaware with my B.S. in Environmental Science (Concentration in Atmospheric Science and Minor in Geography).  While there, I did research on the historical evapotranspiration of the White Clay Creek Watershed.  I also contributed to the Coastal Storm Climatology of Delaware and a paper (still in the works) on the hurricane climatology of the Mid-Atlantic.
