The chemistry department sponsors a weekly seminar series that brings leading experts from around the country to the Vermillion campus to speak about their research. Students also are encouraged to meet with the visitors during their time on campus. Our premier lectures are the Estee and Haines lectures. The Estee Lecture Series, established in 1991, is named in honor of Charles R. Estee, Ph.D., who served the Department of Chemistry for 50 years, beginning in 1947. The Estee Lecture is dedicated to the topic of chemical education and is held annually in the fall. The Haines Lecture Series, established in 1956, is named in honor of Professor Arthur L. Haines, who served the Department of Chemistry for 71 years, beginning in 1904. The lecture is held annually in the spring.
