CORVALLIS, Ore. - A leading expert on the biological underpinnings of amyotrophic lateral sclerosis, or Lou Gehrig's Disease, will speak Tuesday, April 29, at Oregon State University.

Joseph Beckman, holder of the Ava Helen Pauling Chair in the Linus Pauling Institute at OSU, will present "From Pine Trees to the Brain: A Radical View of Lou Gehrig's Disease," at the F.A. Gilfillan Memorial Award Lecture.

It will be from 7:15 to 8:30 p.m. in Austin Auditorium at the LaSells Stewart Center, and is free and open to the public. The event is sponsored by the OSU College of Science.
