Phillip A. Sharp

Phillip A. Sharp is an American molecular biologist and geneticist noted for co-discovering RNA splicing in eukaryotic pre-messenger RNA, a finding that transformed understanding of gene structure and expression and laid groundwork for modern molecular medicine and biotechnology. His work at institutions such as the Massachusetts Institute of Technology, Cold Spring Harbor Laboratory, and the Broad Institute intersected with developments in recombinant DNA technology, cancer genetics, and genomic medicine. Sharp’s research influenced practical advances at biotechnology companies, university research centers, and national science policy organizations.

Early life and education

Sharp was born in Falmouth, Kentucky and spent formative years in Ohio and Michigan. He earned a Bachelor of Science at Union College and a Master of Science at Carnegie Mellon University. He completed doctoral studies at the Massachusetts Institute of Technology under the mentorship of Leonard L. Wofsy and contemporaries including David Baltimore, Howard Temin, and Sydney Brenner. His postdoctoral and early professional networks connected him with researchers at Cold Spring Harbor Laboratory, Rockefeller University, Harvard University, Broad Institute, and laboratories associated with the National Institutes of Health.

Research and discoveries

Sharp’s laboratory at MIT and collaborations with investigators at Cold Spring Harbor Laboratory and Harvard Medical School revealed that eukaryotic genes contain intervening sequences—introns—interspersed with exons, and that pre-mRNA undergoes splicing to produce mature mRNA. This discovery intersected with parallel work by Richard J. Roberts, leading to the 1993 Nobel Prize in Physiology or Medicine awarded to Roberts and Sharp. The finding reshaped interpretations of gene structure originally proposed by investigators such as Francis Crick, James Watson, Rosalind Franklin, and built upon earlier observations by Walter Gilbert and Susumu Tonegawa. Sharp’s studies elucidated mechanisms involving small nuclear ribonucleoproteins (snRNPs), spliceosomal complexes, and regulatory factors connected to p53, BRCA1, BRCA2, and oncogenic pathways explored by researchers at Dana-Farber Cancer Institute and Memorial Sloan Kettering Cancer Center. His research connected RNA processing to alternative splicing phenomena characterized by groups led by Michael S. Waterman, Christopher B. Burge, and Gene Myers, and informed genome annotation efforts at the Human Genome Project, ENCODE Project, and sequencing centers like the Wellcome Sanger Institute and Broad Institute.

Sharp’s contributions extended to studies of transcriptional regulation, RNA polymerase II dynamics explored by teams at Cold Spring Harbor Laboratory and Stanford University, and to mechanistic links between splicing and chromatin architecture investigated by researchers affiliated with Massachusetts General Hospital and Columbia University. His work influenced therapeutic strategies pursued by biotechnology firms such as Genentech, Amgen, Biogen, Moderna, and Roche.

Academic and professional career

Sharp joined the faculty of Massachusetts Institute of Technology where he served as Institute Professor and founded research programs interfacing with the Whitehead Institute, Koch Institute for Integrative Cancer Research, and the Broad Institute of MIT and Harvard. He has held leadership roles at Cold Spring Harbor Laboratory, appointments at Harvard Medical School, and has been involved with corporate boards and startups originating from university technologies, including ventures connected to Alnylam Pharmaceuticals, Dendreon, and Foundation Medicine. Sharp served on advisory panels for the National Academy of Sciences, the National Academy of Medicine, and participated in policy discussions with the White House and the National Institutes of Health. He mentored students and postdoctoral fellows who became leaders at institutions like Stanford University, University of California, San Francisco, Johns Hopkins University, Yale University, Princeton University, and University of Cambridge.

Awards and honors

Sharp’s recognitions include the Nobel Prize in Physiology or Medicine (1993), the National Medal of Science, the Albert Lasker Basic Medical Research Award, the Ludwig Prize, and election to the National Academy of Sciences and the American Academy of Arts and Sciences. He has received honorary doctorates from institutions such as Yale University, Carnegie Mellon University, Harvard University, and Oxford University. Sharp’s membership and honors include fellowships and prizes from organizations including the Gairdner Foundation, the Royal Society, and prizes awarded by the Howard Hughes Medical Institute, Institute of Medicine, and scientific societies such as the American Society for Biochemistry and Molecular Biology and the American Association for the Advancement of Science.

Personal life

Sharp’s personal interests and philanthropy have intersected with scientific institutions including Cold Spring Harbor Laboratory, Union College, Carnegie Mellon University, and regional initiatives in Massachusetts and Kentucky. He has participated in public lectures and symposia at venues such as Carnegie Hall, The Royal Institution, Smithsonian Institution, and collaborated with science policy groups like the Bill & Melinda Gates Foundation and the Robert Wood Johnson Foundation. He is married and has family ties to communities in Ohio and New England.
