Cohen, Sir Philip


COHEN, SIR PHILIP (1945– ), British biochemist. Cohen was born in Edgware, Middlesex, and earned his B.Sc. (1966) and Ph.D., under the supervision of Michael Rosemeyer (1969), in biochemistry from University College, London. After a postdoctoral fellowship with Edmond Fischer at the University of Washington, Seattle (1969–1971), he joined the staff of the University of Dundee, where he progressed to full professor (1981) and Royal Society Research Professor (from 1984). He also became director of the Medical Research Council Protein Phosphorylation Unit and the University's School of Life Sciences. Cohen's research centered on kinases, large families of enzymes which attach phosphate to proteins, and protein phosphatases, enzymes which have the opposite effect. He made pioneering contributions to elucidating these systems, which provide signals regulating normal cell behavior and which are perturbed in many diseases, including cancer and rheumatoid arthritis. In particular, his group identified the enzymes which control the conversion of blood glucose to tissue glycogen and have major implications for understanding diabetes. These discoveries are being applied to the design of novel drugs for treating diseases such as diabetes and cancer. His publications are currently the world's second most cited in biology and biochemistry. His many honors include election to the Royal Society of London (1984), knighthood (1998), and the Bristol-Myers Squibb Award (2002). In 2005 he became president of the British Biochemical Society. His leadership had a major influence in transforming a depressed area of Scotland into a center of scientific and biotechnological excellence. He also delivered many major lectures to Israeli academic institutions.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
