Brief profile

Dr Somers' is a geneticist, who uses the model organism Drosophila melanogaster (fruit fly) to investigate the genetic and molecular mechanisms regulating development. Dr Somers' has developed an interest in the molecular mechanisms of stem cell development, conducting a postdoctoral research at King' College London (supported by a Wellcome Trust Fellowship), Temasek Life Sciences Laboratory, Singapore and The University of Melbourne (supported by an NHMRC Peter Doherty Fellowship). Establishing his own research laboratory at La Trobe University in 2010, Dr Somers' in collaboration with colleagues in the US, Singapore, China and the UK, continues his research on stem cell development as well as teaches both second and third year Genetics units, co-ordinates the departmental Honours program, as well as the fortnightly departmental seminar program. In addition to Dr Somers' contributing to the organising of conferences and meetings, he has been invited to present his research at numerous national and international conferences and research institutes. 

Dr Somers' research interests centre around investigating the molecular mechanisms regulating cellular diversity and cancer development. Using the powerful genetic tools available in Drosophila , conserved factors important for the regulation of stem cell populations can easily be identified. Determining the biological mechanisms of these factors and how they influence proliferation, self-renewal and differentiation, will provide novel insights into stem cell therapies and drug design for the treatment of cancer.
