Professor Ed Louis

Ed Louis grew up in upstate New York, spending most of his time outdoors. Leaving the metropolis of Holland Patent (population: 357) Ed went to study Biology and Mathematics at Clarkson University.

A PhD in Genetics followed in 1986 at the University of California, Berkeley, studying the ‘Population Genetics of Complex Human Traits’. Dr Louis moved into yeast at Brandeis University as a postdoc, then in 1991 as part of the reverse brain drain moved to the Institute of Molecular Medicine, Oxford, as a Wellcome Trust senior research fellow in basic biomedical sciences, continuing to use yeast to study telomeres, genome stability and evolution, as well as developing tools for analysing telomeres from various parasites.

After a brief stint as an Oxford don Dr Louis was rescued from an expanding waistline due to lunches at college by an appointment as professor of genetics at the University of Leicester in 2000.

In 2005 Professor Louis was temporarily wooed away to the University of Nottingham as professor of genome dynamics, returning eight years to the day (1 April 2013) to Leicester as director of the centre for Genetic Architecture of Complex Traits (GACT).

Professor Louis’ research has focused on genetic variation and genome stability in yeast with a particular interest in the ends of the chromosomes or subtelomeres. This has developed in several directions over the years and has included:

• Reproductive isolation and speciation in yeast
• Chromosome evolution in yeast
• Genome stability in various mutant backgrounds
• Telomeres without telomerase
• Subtelomeres in parasites
• Genome dynamics over many time scales
• Population genomics and phenotypic variation
• Most recently, the quantitative genetic analysis of complex traits.

Past funding has come from the Wellcome Trust, the Biotechnology and Biological Sciences Research Council (BBSRC), the EU, the National Institute of Health (NIH), and industrial collaborations.

Current funding is through a Marie Curie Innovative Training Network (ITN, YEASTDOC) and a contract with Phenotypeca Ltd.
