Research Fellow in the Department of Biosciences

Contact Dr. Adrian Christopher Brennan


My research background is in plant population genetics and evolution with a particular focus on plant mating systems, and the molecular and quantitative genetics of adaptation and speciation. Following degree studies in Biological Sciences at Somerville College, Oxford University, I then completed a D.Phil. (PhD) in Plant Sciences, Oxford University, where I investigated the impacts of an invasive population history on the self-incompatibility (SI) mating system of S. squalidus (Oxford ragwort) in the UK. As part of my first postdoctoral position at Bristol University, I expanded this research by investigating the evolution of the SI mating system across an incompletely reproductively isolated species boundary between two Senecio species from Mount Etna, Sicily. In my subsequent postdoctoral position at St Andrews University, I investigated the selective forces and genetic targets responsible for divergent ecological speciation in this study system. More recently, I have researched speciation, population, and quantitative genetics in Begonia (Royal Botanic Garden Edinburgh) and Arabidopsis (Estación Biológica de Doñana, EBD-CSIC, Seville) including dealing with new genetic technologies such as transcriptome analysis and high-throughput SNP genotyping.

Research Interests

My primary research interests and experience are in ecological and quantitative genetics of hybridization, speciation, invasiveness, and plant reproductive systems. I am currently investigating the genetic basis and evolution of mating system, flowering initiation, and other adaptive trait variation in the genus Linum (flax/linseed) using a combination of transcriptome sequencing and genotyping by sequencing. I am also involved in collaborative research studying rapid evolution in the invasive weed, yellow starthistle, and the genetic variation of wheat landraces from the middle east.
