My research focusses on the underlying molecular mechanism by which bacteria perceive their surroundings through regulatory signals – and how they integrate multiple signals to effect appropriate changes in their gene expression. My goal is ultimately to determine their lifestyle and behaviour.
One of my research group’s major emphasis is on signal transduction cascades that control degradation of toxic environmental pollutants by soil bacteria such as Pseudomonas putida, and those that control production of the type VI nano-machine deployed by Vibrio cholerae during inter-bacterial competition.
I graduated with a BSc in Biological Sciences from Leicester University, UK in 1980 and obtained my PhD in Molecular Genetics in the laboratory of Christopher M. Thomas at the University of Birmingham, UK in 1984. I performed my post-doctoral research within the laboratory of Michael Bagdasarian (1985-1987), at what is now the Department of Molecular Biology at Umeå University.
I have remained in Sweden at the same institution ever since, first as a group leader (1987-1989) and then as a lecturer (docent, 1990-1995). In 1995 I was awarded a ‘Särskild forskartjänst’ – a special six year researcher position sponsored by the Swedish Natural Science Foundation (NFR). During the time frame of this NFR position (1995-2002), I was appointed to my current position as a Professor in Microbial Physiology in 1996.
