The Department of Biology sponsors a weekly seminar series during the Fall and Spring semesters. Seminars are held each Tuesday at 4:00 p.m. in Biological Sciences Building East (BSBE), room 115. In addition to this weekly seminar series, the department hosts the Walker Endowed Lectureship. If you would like to be added to our weekly seminar e-mail reminder, please send your name and e-mail address to McKensie Le Fevre at


Emily and Robert Walker ’45 Lectureship in Biology

Originally formed as the Frontiers in Biology lecture series, the Departmental lectureship was established in 1984 as a mechanism to attract prominent scientists to Texas A&M University for an extended visit with our faculty and students. This program of formal seminars and relaxed one-on-one interactions has enabled faculty and students from our department as well as other departments on campus to hear first-hand about the forefront of biological research from the leading figures of various biological disciplines. In 2009, the Frontiers in Biology Lecture became the Emily and Robert Walker ’45 Endowed Lectureship in Biology.

Emily Walker is a resident of Dallas, Texas. Robert Walker, a world-renowned clinician and educator, passed away on April 28, 2011.

Emily attended UT and is a weaver. An active member of the Spinners and Weavers Guild in Dallas, she grows her own cotton in whiskey barrels in the backyard and has it ginned at the TAMU Extension Service.

Robert began at TAMU in 1941 just before the U.S. entered World War II. He had a strong interest in the Department of Biology’s program in pre-medicine and pre-dentistry. Although he was a member of TAMU’s class of ’45, he was drafted into the army in 1943 and assigned to the Baylor College of Dentistry in 1944. He earned a DDS degree there in 1947, and had a general practice in Waco, Texas, until 1951. He then was called back into the army during the Korean War. In 1953 he went to Graduate School of Medicine at the University of Pennsylvania, and from 1954-56 he did a residency in oral surgery at Parkland Memorial Hospital in Dallas.

He was appointed to the Department of Surgery, UT Southwestern Medical School in 1956 to create the Division of Oral Surgery where he remained throughout the rest of his career, training over 200 residents. Among his many professional honors, he is a Fellow of the Royal College of Surgeons in England and a Fellow of the Royal College of Surgeons of Ireland. Over the years, Dr. Walker retained close ties with TAMU, and he was actively involved in many of its organizations and advisory boards.

The Emily and Robert Walker ’45 Endowed Lectureship in Biology was established in 1995 to bring to the attention of the TAMU community outstanding research in the biological sciences.
