Lawler began her work on the newly discovered rhesus blood-group system, and in 1949 she was invited to join the world's first department for the study of human genetics at Galton Laboratory at University College, London. She went on to publish a book entitled Human Blood Groups and Inheritance in 1963. Other publications during this period included A Genetical Study of the Gm Groups in Human Serum in 1960 and A pedigree showing some rare Rh genotypes. Lawler was appointed as research scientist at the Institute of Cancer Research in London in 1960 and became the institute's first female professor in 1980. There she developed a broad interest in the genetics of malignancy. She made major contributions to the development of these tissue-typing techniques. Lawler laid the scientific foundation for work in bone-marrow transplantation and became chairman of the transplantation immunology subcommittee of the National Organ-Matching Service. She was a founder member of the International Workshops on Chromosomes in Leukaemia, and also established the first national fetal tissue bank in the UK, with support from the Medical Research Council.
Publications
During Lawler's career she published a wide variety of journal articles, including Leukaemia; The relation of parental sex and age to recombination in the HL-A system; Cost of bone-marrow transplants in acute myeloid leukaemia; Fetal tissue typing; Genetic studies of complete and partial hydatidiform moles; Histocompatibility antigens in asthma: population and family studies, and Chromosomal damage and hair dyes.
Scientific interests
A principal interest was in the genetic basis of trophoblastic disease, which encompasses molar pregnancies and choriocarcinoma, and in efforts to improve the diagnosis and treatment of this disease. Lawler's work on histocompatibility leukocyte antigens provided evidence that choriocarcinomas may arise from an earlier rather than simply the antecedent pregnancy. She went on to use genetic polymorphisms to determine the origins of complete and partial hydatidiform moles. Lawler was also a pioneer in the analysis of the human genome. She was a foundation member and fellow of the Royal College of Pathologists and an honorary fellow of the Royal College of Physicians.
Awards
Lawler's lifetime work was recognised in the form of the Royal Society of Medicine Syliver Lawler prize, each year two prizes are offered for the best scientific paper and the best clinical paper. Abstracts from scientists and clinicians in training on a clinical or basic scientific research project, and a panel of judges determine the best oral presentation. It is highly competitive and well recognised award in the field of oncology.
