Personal Profile


I am interested in how hormones affect diverse physiological processes and behavioural outcomes throughout the life course.

I am currently investigating the role of oxytocin in regulating appetite and obesity, working within a multidisciplinary team as part of the Leng and Ludwig research groups. I focus on the in vivo aspects of the project, employing chemogenetic techniques coupled with behavioural and biochemical assays in the rat model.

I completed my PhD training with Dr Paula Brunton, where I investigated the role of steroids in mediating the outcomes of stress during pregnancy. I also developed and validated a liquid chromatography-mass spectrometry method to measure neurosteroids, shedding light on the complex interaction between steroids, stress, and biological sex.
