Keynote Address

Shirley Tilghman, Ph.D.

Shirley Tilghman

Dr. Shirley M. Tilghman was elected Princeton University's 19th president on May 5, 2001, and assumed office on June 15, 2001. An exceptional teacher and a world-renowned scholar and leader in the field of molecular biology, she served on the Princeton faculty for 15 years before being named president.

A native of Canada, Dr. Tilghman received her Honors B.Sc. in chemistry from Queen's University in Kingston, Ontario, and her Ph.D. in biochemistry from Temple University. During her scientific career as a mammalian developmental geneticist, she studied the way in which genes are organized in the genome and regulated during early development. A member of the National Research Council's committee that set the blueprint for the United States effort in the Human Genome Project, she also was one of the founding members of the National Advisory Council of the Human Genome Project for the National Institutes of Health. Dr. Tilghman was appointed an investigator of the Howard Hughes Medical Institute in 1988, and in 1998 was named the founding director of Princeton's multidisciplinary Lewis-Sigler Institute for Integrative Genomics. She is the recipient of a Lifetime Achievement Award from the Society for Developmental Biology, the Genetics Society of America Medal, and the L'Oreal-UNESCO Award for Women in Science. She is a member of the American Philosophical Society, The National Academy of Sciences, the Institute of Medicine, and The Royal Society of London. She serves as a trustee of the Carnegie Endowment for International Peace and the King Abdullah University of Science and Technology, and as a director of Google Inc.

Dr. Carolyn Peluso is a Technical Writer and Cell Biology Specialist at the American Type Culture Collection (ATCC). She earned her Ph.D. from Tufts University and did her postdoctoral training in NICHD in the laboratory of Dr. Mihaela Serpe.

In her academic career, she has sought to answer questions related to how cellular patterning occurs. As a graduate student her research focused on understanding how olfactory sensory neurons are patterned across the epithelial plane of the mammalian olfactory epithelium. As a postdoctoral fellow, her work explored how the processing of a BMP-binding protein helps to create a step-gradient of BMP, which is required for the proper dorsal-ventral patterning of the Drosophila embryo.

Currently, Dr. Peluso is a Technical Writer in the Marketing Department at ATCC. Here, her responsibilities include managing the marketing team's editorial calendar and preparing materials, such as application notes, to support the products in the collection. In addition, she helps support the company's position as a thought-leader in the scientific community by writing editorial articles for relevant trade publications. Dr. Peluso recently co-authored a piece on biobanking for Genetic Engineering and Biotechnology News and a piece on the need for cell authentication for Drug Discovery News.
