In addition to 23 refresher courses, 28 symposia, 15 workshops, and 4 plenary lectures, you will have ample time (and space) to present your research through numerous poster sessions (posters will be displayed for the entire duration of the meeting this year). A special social event is scheduled for Sunday night. The Puerto Rican Tourism Office will sponsor a "Tropical Night Mixer," featuring native music and dance of Puerto Rico and a taste of Puerto Rican delicacies. We are delighted to host Dr. Ellen Baker, NASA Shuttle Astronaut, who will be a featured speaker in the NASA Space Radiobiology Symposium. She will also speak during the RRS Women’s luncheon on Monday. Our plenary lectures this year will center about the theme of molecular targets featuring Joe Gray, UCSF, (Genome Evolution in Solid Tumors: Clinical Correlations and Therapeutic Targets); Dan Kenan, Duke University, (Designer Ligands for Molecular Targets) and Ed Liu, NCI, (Therapeutics in the Genomic Era). Les Redpath, RRS President, will host the Presidential Symposium on "Genes, Radiation, and Cancer." Our young investigators will enjoy not only platform presentations of their research, but a special social mixer and a luncheon.

Many of the special functions and activities of the meeting have been underwritten by our Institutional and Corporate members and by gracious contributions made by a number of companies and organizations. The names of these contributors will be placed on signs throughout the meeting facility. Also, we will have several corporate exhibitors at the meeting; please take a few minutes to stop by and visit with them. We are grateful for their help and support.

A free afternoon (Tuesday) will give you the opportunity to enjoy the beach or visit old town San Juan that features numerous restaurants, nightclubs, shops, and historical sites. You might want to check out the Puerto Rico website (www.prtourism.com) to plan activities before or after the meeting.
