Before joining the full-time Atmospheric Sciences faculty in 2012, Janel Hanrahan earned her Ph.D. in Mathematics with a strong focus in Atmospheric Sciences from the University of Wisconsin-Milwaukee. Her dissertation work included the investigation of Lake Michigan-Huron water levels and their connection to natural climate variability and anthropogenic climate change. Following graduate school, Dr. Hanrahan worked as researcher at the University of Alberta where she studied changes in rainfall in the Canadian Plains region and examined procedures for model optimization. Through dynamical and statistical downscaling, she is currently interested in identifying connections between large-scale climate shifts and local precipitation trends. In addition, she is interested in investigating how regional weather will be modified under climate change and what impact this may have on renewable energy sources.

At Lyndon State College, Dr. Hanrahan enjoys interacting with students on a personal level both in and out of the classroom. She earned her own B.A. from a small student-centered institution and was excited to return to this type of learning environment. Because of her own interest in applied mathematics, she enjoys communicating the science to potential future LSC Atmospheric Science students who share an interest in math and physics by presenting at math conferences and local K-12 schools.  She is also working with a group of LSC students to communicate the science of climate change to the general public.   For more information, see Climate Change Communication.

Originally from the Midwest, Dr. Hanrahan has been enjoying the Northeast Kingdom’s natural beauty. She just purchased her first home and looks forward to spending her free time renovating, gardening, and exploring the surrounding area. She is also excited to be a mother, as she and her husband recently had their first child.
