Dr. Pat Gillevet divingDr. Patrick Gillevet

Dr. Gillevet is an Associate Professor at The Institute for Bioscience, Informatics and Biotechnology, George Mason University. He has worked on a number of molecular biology projects over the past 15 years. Those projects range from studying human diseases, to sequencing the genetic components of prokaryote cells as a way to understand the evolution of genes and proteins. Pat's efforts have resulted in a number of improvements in sequencing technology and have contributed to the understanding of the evolutionary history of nuclear and mitochondrial DNA, and proteins. In addition to his current position, he has carried out his research as a Visiting Scientist at the National Center for Human Genome Research, NIH, as Director of the Harvard Genome Laboratory, Harvard Biological Laboratories, and as Technical Director, at the Center for Prokaryotic Genome Analysis, Department of Microbiology, University of Illinois, Urbana. Pat received a B.Sc. in Microbiology from the University of Toronto, and a Ph.D. in Biochemistry from the University of Manitoba.

His area of specialization is systematics of gastropod mollusks, and he is forever working on molluscan systematics, especially collection-based research. José's formal education was completed at the Federal University of Rio de Janeiro, Brazil, where he received a B.S. in Marine Biology, and an M.S. in Invertebrate Zoology, and a Ph.D. at the University of Miami in Marine Biology and Fisheries. He was Visiting Professor at the Laboratoire de Malacologie, Muséum National d'Histoire Naturelle, Paris, France (1988), Postdoctoral Fellow at the Smithsonian Institution's National Museum of Natural History (1992-1993), and Postdoctoral Associate at the Division of Marine Geology and Geophysics, University of Miami (1994-1995). Dr. Leal currently holds positions as Adjunct Professor in the Division of Marine Biology and Fisheries, University of Miami; Courtesy Faculty Appointment, College of Arts and Sciences, Florida Gulf Coast University, Fort Myers; Temporary Member of the Graduate Faculty of the University of Alabama (Department of Biology); Councillor-at-Large and member of the Nominating Committee of the American Malacological Society (1999-2000); delegate of the U.S. in the Organizing Committee for Latin American Malacological Congresses (1999-2002); Editor-in-chief, The Nautilus (oldest malacological journal in the world); member of the editorial committee of American Conchologist, and Arquipélago--Life and Marine Sciences.

Steve Pappas is a visiting scholar at the Smithsonian Institution with over 28 years of experience in Education and International Affairs. He is working to find new and interesting ways to bring the Joys of Discovery and the Joys of Research at SI to the attention of Educators and learners. He served most recently as the Director of the Federal TRIO Programs, a $600 million dollar U.S. Department of Education program that funds over 2000 education projects throughout the nation. He has served on the President's Commission on Foreign Languages and International Affairs, the Thomas Jefferson Commemoration Commission and the Japan-US Friendship Commission. He was Deputy to the Education Attaché at the U.S. Permanent Delegation to UNESCO in Paris, France. His interests include furthering Academics at all levels of education with special focus on the student, Life-long Learning, and the history of ideas.

He received his undergraduate and graduate degrees from Columbia University in New York City.

Chip Clark at work in a subChip Clark

Chip has been a staff photographer for the Smithsonian's Museum of Natural History since 1973. His official title "Scientific and Studio Photographer" understates the range of his assignments and techniques, including macrophotography, high speed and time lapse cinematography, and imaging in the infrared and ultraviolet wavelengths. His atypical studio subjects include dinosaurs, mummies, living insects, skulls, famous blue diamonds, and the occasional grumpy scientist. On scientific expeditions, Chip has found himself photographing caves in Jamaica and Guatemala, coral reefs in Belize and Cuba, the Amazonian rainforest of Peru, Kwakiutl ceremonial dances in British Columbia, and street folk artists in India. He finds this voyage on the Johnson Sea-Link I submersible and the RV/Edwin Link delightful because it has electricity, no biting insects, and he doesn't have to sleep on the ground. Chip has a B.Sc. in Biology from Virginia Polytechnic Institute and has worked for NASA (Langley AFB), taught high school (Newport News, Virginia) and does freelance photo assignments for the National Geographic Society, National Wildlife Federation, and the publishers of Scientific American.

Robert CostelloRobert Costello

Robert is the Multimedia Specialist at the National Museum of Natural History, Smithsonian Institution, Washington, DC, and he is responsible for developing this website. He has long been involved in science education and primate evolution. His interest in representing museum specimens in digital form dates back to a ten-year period spent at the American Museum of Natural History, New York City, where research was conducted using digital imaging technology for 2- and 3-D analysis of primate specimens. Robert also has a dozen years of experience teaching math and science at the primary, secondary, and post-secondary levels. He ran the CUNY Headstart for College Continuum Precollege Institute, a program for inner-city high school students in New York City. He earned a bachelors degree in Anthropology at Southern Illinois University, and a masters degree from Hunter College of the City University of New York.

Harold M. M. Tovell, M.D.Harold M. M. Tovell, M.D.

After receiving his medical degree from the University of Toronto Medical School, Harold served for three years as a medical officer in the Canadian army. He arrived in the United States in 1949, and spent five years in residency training at Columbia University, College of Physicians and Surgeons in the Department of Obstetrics and Gynecology and Gynecologic Oncology. He remained on the teaching staff of the Department for seven more years before being appointed chief of the Obs/Gyn service at Columbia University's affiliated, Woman's Hospital. Following a long, active practice, and academic life, Harold retired in 1987, and he and his wife moved to Sanibel Island where he became involved in the beginnings of the Bailey-Matthews Shell Museum, the only museum in North America devoted entirely to malacology. He served a two years term as President of the Board of Trustees, and through the museum, he continues his strong commitment to education, research and academics.
