Dr Sarah-Jane Guild

PhD (Physiology and Electrical & Electronic Engineering), ME (Engineering Science)


My interest in physiology and engineering has developed into my two complementary current positions (0.5 FTE each) as a Senior Research Fellow in the Department of Physiology and Chief Scientific Officer at Kaha Sciences Ltd. Kaha Sciences specialises in small animal telemetry and sells a wireless telemetry system developed in our laboratory and commercialised in 2004.

With a background in physiology and engineering, my university research involves the collection and analysis of physiological data from animal models in both control and disease states. My current research focuses on the interactions between arterial pressure and intracranial pressure in normal and hydrocephalus (raised intracranial pressure) animal models. I have developed techniques to chronically record intracranial pressure in both rats and sheep which allows us to take advantage of the benefits of working with both small and large animals in our studies.

This recent focus on intracranial pressure has grown from a collaboration with the Implantable Devices Group at the Auckland Bioengineering Institute to develop a fully implantable clinical device to allow the chronic measurement of intracranial pressure in patients with hydrocephalus. We are now also applying similar technologies to the development of an implantable light source for optogenetics therapies and are exploring its application in small and large animal models.

In both my university research and commercial work, I have developed an international reputation in the field of chronic recordings using telemetry. I have visited and provided surgical training for researchers in several major pharmaceutical companies, universities and the FDA. Both my PhD and Master of Engineering degrees were cross discipline, allowing me to take the analytical skills of my engineering background and apply them to the challenging area of physiology.

I believe my two roles have complemented each other well with my scientific background being invaluable in my commercial role and my interactions with customers and the more controlled design process enriching my academic research and student supervision.
