Research Interests

Dr. Kristin Poinar studies earth’s ice sheets, especially the Greenland Ice Sheet, as well as Antarctica and past ice sheets (e.g., the Laurentide).  I ask questions about ice dynamics and the interactions between ice flow and liquid water.  How, when, and where does surface melt water get to the ice-sheet bed, and how does this affect ice dynamics?  My primary tool is process-scale ice-sheet models, and I incorporates remote sensing data into developing these models.

Student research

There are opportunities for undergraduate (including gap year “research month” experiences), Master’s, and PhD work in my lab, for students with quantitative backgrounds or interests.  If a certain research topic interests you, send me an email or drop in to my office to tell me why you’d be a good fit!
