Timothy J. Shafer, US Environmental Protection Agency, Research Triangle Park, North Carolina, will deliver the In Vitro Lecture, “Can In Silico and/or In Vitro Testing be used for Toxicity Assessment Instead of In Vivo Approaches?,” Monday, March 12, 12:00 noon–1:20 pm, Marriott Marquis, Golden Gate Ballroom B, hosted by the SOT Education Committee and sponsored by the Colgate-Palmolive Company. The goal of the In Vitro Toxicology Lecture series is to feature important research using in vitro and alternative techniques to study basic mechanisms and to illustrate how these test methods benefit animal welfare by refining, reducing, and replacing animal use whenever it is feasible. Graduate students, undergraduates, postdoctoral scholars, and recipients of Colgate-Palmolive awards are among the guests at the In Vitro Toxicology Lecture and Luncheon. Students and postdoctoral scholars should have registered via the Annual Meeting registration, and the $10 deposit will be returned upon entry to the event. Dr. Shafer will present an introduction to the topic, and then participants will discuss related questions and report responses. Scientists who wish to participate may do so on a space available basis.
