Loma Linda University Graduate School News
Department of natural sciences faculty, graduate students, and alumni present papers at national meetings in Denver in November Four department of natural sciences faculty members and eight graduate students attended the annual meetings of the Geological Society of America and the Society of Vertebrate Pale ontol ogists in Denver in November. Eleven papers were presented at the meetings. At least one author of each of the papers was either a Loma Linda University faculty member or graduate student. "The senior authors of nine of the papers were from Loma Linda," says Leonard R. Brand, PhD, professor of natural sciences. University faculty members who were senior authors include H. Paul Buchheim, PhD, professor of natural sciences; Robert A. Cushman, PhD, assistant professor of natural sciences; and Kevin E. Nick, PhD, assistant professor of natural sciences. Graduate students who also participated in the authorship of the papers include Roberto Biaggi, Gerald Bryant, Cristian Carvajal, Raul Esperante-Caamano, Leroy Leggitt, Mark Loewen, Richard Peters, and John Whitmore. Two other papers were presented either by alumni or former faculty members of Loma Linda. "The Loma Linda papers covered such diverse topics as fossil insect larval cases in ancient lake deposits, fossil whales in Peru, fossil birds, the geology of a gold and copper ore deposits in Chile, sedimentary processes in sandstone, and computer-aided radiographic imaging of fossils within rock," Dr. Brand states. Nobel prize winner to speak at basic science seminar Nobel prize winner Richard J. Roberts, PhD, research director at New England Biolabs, Beverly, Massachusetts, will deliver the inaugural Raymond Ryckman Lectureship on Thursday, January 13, 2000, at 1:15 p.m. in the amphitheater of the Alumni Hall for Basic Sciences. Dr. Roberts, who won the 1993 Nobel prize in medicine, was born and educated in England, attending Saint Stephen's School and the City of Bath Boys' School before moving to the University of Shef field where he obtained a bachelor's degree in chemistry in 1965 and a doctor of philosophy degree in organic chemistry in 1968.
Dr. Roberts has been involved in many projects including studies of Adenovirus-2 beginning with studies of transcription that led to the discovery of split genes and mRNA splicing in 1977. This was followed by efforts to deduce the DNA sequence of the Adenovirus-2 genome and a complete sequence of 35,937 nucleo tides was obtained. This latter project required the extensive use of computer methods, both for the assembly of the sequence and its subsequent analysis. The Raymond Ryckman Lectureship is being endowed in the department of microbiology and molecular genetics in the School of Medicine by Dr. Ryckman's family in honor of his distinguished service as chair and professor in the department. Further information about Dr. Roberts' visit or the Raymond Ryckman Lectureship may be obtained by calling the department at (909) 558-4480. University
