Research summaryNeuroendocrine regulation of body weight and glucose homeostasis

Research

Working with Dr Alex Tups and Professor Dave Grattan's research groups. Research interest includes investigating mechanisms that causes leptin resistance, which is a hallmark of obesity, in response to high fat diet. And to understand the specific neuronal pathways involved in regulating bodyweight and glucose homeostasis.
