Dr. Frederick Grinnell, an author and cell biologist at UT Southwestern Medical Center in Dallas, will speak on ethics and scientific research on Monday, Nov. 26, in the Science Building auditorium.

The lecture, which is free and open to the public, will begin at 6:30 p.m. and is sponsored by Sigma Xi, the scientific research society.

Grinnell is founder of the ethics in science and medicine program at UT Southwestern, where he has taught cell biology since 1972.

In bioethics, Grinnell engages in cross-disciplinary work at the boundary between science and philosophy, according to his website at UT Southwestern. His goal is to inform public policy and to advance science education and public understanding of science. Grinnell's work in bioethics is centered in the sociology of knowledge.

He has published two books: The Scientific Attitude, now is in its second edition; and Everyday Practice of Science: Where Intuition and Passion Meet Objectivity and Logic, which was a finalist in the 2010 Royal Society Book Prize competition.
