These were just a few of the questions asked by more than 300 students and faculty in the College’s School of Sciences and Mathematics this academic year. And last week, on April 16, 2015, they provided some answers at the school’s 27th annual poster session, highlighting just a portion of the scientific and mathematical research that occurs each year at the College.

Students working with faculty advisors presented 132 posters this year, as summarized in this list of abstracts.

Among the research projects, several were singled out for awards, including research done by Haley Cabaniss, who was named “Best in Session” for her geological study of how to better predict the eruption of volcanoes.
