Eligible to supervise Masters and PhD - email supervisor to discuss availability.

Dr. Melissa Humphries is a statistician – she creates, and applies, analytical tools that make sense of our world. Working in areas like forensic science, health and psychology, the goal is always to increase efficiency, accuracy, and transparency. Building bridges between machines and experts, Melissa’s work aims to support experts in making decisions in an explainable way.

Working at the interface between statistics and AI, Melissa's research draws meaning out of complex systems by leveraging the explainable components of statistical and physical models and elevating them using novel techniques. She strongly advocates the integration of the end-user from the outset of all research and is committed to finding impactful ways to implement science.

Melissa is also a passionate advocate of equity across all areas of her work and life.
