Desrochers organizes “Arkansas STEM Posters at the Capitol”
On February 15 eighty undergradeuate students from 14 different Arkansas public and private colleges and universities participated in the "2012 Arkansas STEM Posters at the Capitol", the brainchild of UCA Chemistry Professor Patrick Desrochers. Attendees at the two-hour session included Governor Beebe and approximately 25 members of the Arkansas Legislature. Students discussed their work in the natural sciences, computer science, engineering and mathematics to legislators and the general public. They also will provide first-hand experiences about their promising educational opportunities in undergraduate research in technical science, technology, engineering and mathematics (STEM) fields.
“This should become something the legislators and public anticipate, a showcase of the best and brightest students from around the state involved in exciting and innovative projects. In the end, this should advocate for the good the work these students and faculty do at their schools," he said. "Most importantly, this advocacy comes from the students themselves who benefit most from the experience. Hopefully, this poster session will help it become widely known that outstanding educational opportunities are available right here in Arkansas in highly technical, exciting, challenging, and sometimes financially lucrative fields, following undergraduate and graduate training. Arkansans should know these opportunities exist at schools throughout the state. Arkansas STEM students who go and present their work at national meetings see that even though they are from a smaller state, their original work is often of equal technical stature compared to other students and scientists all over the country and sometimes the world.”
A video of the event is available.
