Education

Lawrence was educated at Wennington School in Wetherby, and then at St Catharine's College, Cambridge; he gained his doctorate as a student of Vincent Wigglesworth for work on Oncopeltus fasciatus (milkweed bug).^[4] His postdoc in the USA was funded by a Harkness Fellowship.

Career and research

Lawrence's main discoveries lie in trying to understand the information that shapes an animal or generates a pattern (such as on a butterfly wing or a fingerprint). He is a principal advocate of the theory that cells in a gradient of a morphogen each develop according to the local concentration of that morphogen and that this mechanism thereby patterns fields of cells. Together with Ginés Morata, he has helped establish the compartment theory. Under this hypothesis a set of cells collectively builds a precisely defined territory (or compartment) in the animal. As development proceeds, a selector gene switches on in a subset of these cells thus dividing the set into two, all the progeny of each set construct one of the two adjacent compartments.^[5] Much of the evidence for the hypothesis comes from studies on the abdomen of Oncopeltus^[6][7] and the Drosophila fly wing.^[8]

Since the mid 1990s he has collaborated with José Casal, Gary Struhl, and others to study Planar Cell Polarity (PCP) and cell affinity. PCP is a common property of cells which can show coordinated polarity in the plane of the epithelia. PCP is often revealed by the consistent orientation of visible structures such as cuticular bristles in insects or hairs in mammals. Using the powerful genetics of Drosophila, particularly the ability to make genetic mosaics, Lawrence and his colleagues provided evidence that there are two separate molecular/genetic systems that build PCP. At the heart of each system is a gradient of a molecule that extends across the tissue. The local slopes of these gradients are detected by means of molecules that form intercellular bridges and are used to orient PCP in each cell.^{[9] [10]} Casal, Lawrence and their group have now demonstrated and measured the two molecular gradients in vivo.^{[11] [12]} His research was funded by the Medical Research Council, the Wellcome Trust and the Leverhulme Trust.

Publications

Peter Lawrence's publications indexed by Google Scholar are also listed in his personal web site.^[13]

Lawrence wrote the book The Making of a Fly in 1992,^[2] which explains how the body plans of flies are constructed. Findings on the fly have strong implications for other animals such as mammals. The book received further “recognition” in April 2011 when fellow biologist Michael Eisen discovered two booksellers were programmatically setting increasingly higher prices for copies of the book on amazon.com used book market. Margrethe Vestager (European Commissioner for Competition) mentioned this event as an early example of algorithmic tacit collusion on March 16, 2017.^[14][15] The sellers eventually priced copies over 23 million USD before the feedback loop was broken.^{[16][17][18][19]}

Lawrence has also written many commentaries on the ethics of science practice,^[20][21][22] as well as obituaries of Michael Berridge, Sydney Brenner, Francis Crick, and Ed Lewis.^[23]

Awards and honours

Lawrence was awarded membership of the European Molecular Biology Organization (EMBO) in 1976;^[24] he was elected a Fellow of the Royal Society in 1983;^[25] awarded the Darwin Medal in 1994;^[26] and with Ginés Morata was a recipient of the Prince of Asturias Prize for scientific research in 2007;^[27] he was elected a foreign member of the Royal Swedish Academy of Sciences in 2000.^[28]

Personal life

Lawrence married Birgitta Haraldson in 1971,^[1] a clinical psychologist and expert on autism.
