About Me
I'm a planner with a love for data analysis. I hate setting goals, as I fear they may limit my choices and possibilities. I make decisions quickly and confidently, but put them off until the last minute so I never miss an opportunity. Surprises are the worst - I prefer to have all the information possible about any subject I'm diving into, from job opportunities to memorizing directions to lifestyle choices. I completely enjoyed my one-time three week research experience at sea, but prefer to do my work with the aid of a computer - processing data or running models. One of my best talents is appearing as a normal, non-scientist person, and explaining science concepts to anyone. I make good use of this skill in my blog, Just Swimmingly.
I'm currently a Postdoctoral Research Associate at the Applied Physics Laboratory, University of Washington, working on regional ocean models of Antarctic Shelf Seas with a focus on ocean-ice shelf interactions.

Current & past projects
Mesoscale eddies & ice shelf melt
Using ROMS, a regional ocean model, I examine how well mesoscale eddies are represented in the model at different horizontal resolutions and find it depends on stratification, season, and location. I then examine if these eddies have a significant effect on ice shelf basal melt rates (they don't). Resulted in many conference presentations, one first-author paper in prep.
Iron Transport Pathways
As part of my dissertation work, I use passive tracer dyes in a regional ocean model to track iron sources and how they vary with tides and mesoscale eddies. This modeling work supports a larger project: "Processes Regulating Iron Supply at the Mesoscale - Ross Sea (PRISM-RS)". Resulted in several conference presentations, three co-authored papers, one first author paper.
Tides & Sea Ice
I used time series analysis and developed a new method to quantify, using satellite observations, how tidal forcing affects sea ice concentration in the Ross Sea, Antarctica. Resulted in many conference presentations, a poster award, and a first-author paper.
