I'm a biologist with an MSc in palaeobiology from Bristol University who loves talking about science! I work in the Learning Department of the Natural History Museum in London.

Some of the things I have worked in - or like to read about - are (in no particular order): Animal behavior, dinosaurs, pet keeping, learning and education, botany, palynology, aquariums, zoology and physiology... I'm a geeky enthusiast but not an expert in any of these fields!

I also enjoy playing the guitar and have read every single Sherlock Holmes story at least twice...

Hope you enjoy your visit to Ask A Biologist,

I am a postdoctoral research associate at the University of Leeds, in the Faculty of Biological Sciences. I work in the field of bacterial molecular genetics, mainly with Staphylococcus aureus (and many antibiotic resistant strains thereof), looking at the evolution of bacterial fitness. In addition to bacteriology, I have interests in evolutionary biology, plasmid biology, entomology and geology.

I'm a vertebrate palaeontologist, working mainly on Computer Aided Design and Computer Aided Engineering modelling of dinosaurs. This means that I look into the range of motion, the posture, the center of mass position, locomotion cylces and so on.

I am a medical doctor. I have trained in general medicine and then specialised in endocrinology. This is a branch of medicine that manages disorders of the endocrine system and its secretions called hormones. These are chemical messengers that communicate between various organs and tissues in the body. They are secreted into the blood and are the means by which one gland can “talk” to another gland/tissue to alter its function. My particular area of interest is in neuroendocrinology which involves how areas of the brain (such as the hypothalamus and pituitary gland) control the secretion of hormones from other endocrine glands. My other specific clinical interests include pituitary and adrenal gland diseases and neuroendocrine tumours.

I got my PhD in palaeontology at The University of Adelaide (South Australia) working on fossil Bryozoa. I now work as the Collection Manager of Invertebrate Palaeontology at Melbourne Museum, and continue to do my own research.

I am a postdoctoral fellow in the Prud’homme and Gompel lab at the IBDML in Marseille. My current research focuses on understanding the evolution and genetics of innate courtship behavior in diverse fruit fly species. I completed my PhD thesis in 2009 at UC Berkeley, where I studied the evolution of dorsoventral (the back-belly) axis patterning in insects such as honeybees, flour beetles and fruit flies. My background is primarily in evolution and development (evo-devo), genetics and molecular biology. Behavior is a new direction for me.

I am a final year PhD Student at the University of Aberdeen. My PhD is mostly Pharmacology based, looking at cell receptors which might play a role in some cancers and disease.
My first degree was in Molecular Biology and Biochemistry from the University of Durham.
