Postdoctoral Research Scientist/ Senior Postdoctoral Research Scientist (Signalling)

Starting salary is £32,200 per annum to £46,000 per annum 

(depending on experience)

The Babraham Institute is a charity which is world renowned for its research in life sciences to enhance lives and improve wellbeing.

We are seeking an enthusiastic Postdoctoral Research Scientist or Senior Postdoctoral Research Scientist to join Heidi Welch’s group in our Signalling Programme, to study cell signalling through Rac Small GTPases and Rac-GEFs.

Rac family Small GTPases control cytoskeletal dynamics to regulate cellular processes such as adhesion, migration and vesicle trafficking. We study the importance of the activators of Rac, Rac-GEFs, in these processes. Rac-GEFs greatly outnumber Rac GTPases, and we are interested in the diversity of Rac-GEFs, aiming to understand their unique roles in various systems. Currently, we are investigating the roles of P-Rex and other Rac-GEFs in the clearance of bacterial infections, in glucose homeostasis and in receptor trafficking processes. We are also interested in the molecular mechanisms that regulate Rac-GEFs, and we are generating new tools for monitoring Rac-GEF activity, using these to study how Rac-GEFs integrate upstream signals to generate the subcellular patterns of Rac activity that elicit specific cell responses.

This postdoctoral position plays a central role in our research programme, combining methods such as molecular and cell biology, biochemistry, imaging and various models of health and disease, including in vivo animal models. In addition to conducting his/her research in one or more of the areas outlined above, the post holder will help with training the lab’s graduate students and with outreach activities. S/he will benefit from the Institute’s world-leading expertise in signalling, from our excellent research facilities, and from existing external collaborations within the UK and internationally.


The successful candidate must have a PhD in biology, biochemistry or related disciplines, with a demonstrable track record in signalling research. Experience in molecular biology, cell biology, protein biochemistry and imaging techniques is essential. Experience in Small GTPase/GEF biology and with animal models of disease is highly desirable.

The level of which the candidate is employed at will be decided at appointment by the interview panel. Funding for this position is available for three years in the first instance.

Informal enquiries can be made to Dr Heidi Welch:
