Research

I am currently researching the mechanisms by which steroid hormones such as androgens and estrogens act in the hypothalamus and pituitary to control male reproduction and testosterone production.

I am also interested in improving the way that biological pathways are depicted as diagrams and have been involved in developing the modified Edinburgh Pathway Notation (mEPN) for use as a dynamic modelling system.
