Professor Alistair McEwan
Today's guest is Professor Alistair McEwan who is a prolific prototyper of medical devices especially around the brain and sensing the bodies various different signals.

• BE/BComm MEng(Res), Sydney, Australia. Ph.D., Oxford, UK. MIEEE
• Ainsworth Chair of Technology and Innovation
• School of Biomedical Engineering
• Cerebral Palsy Alliance
• Chief Investigator - ARC Training Centre for Innovative BioEngineering
• Lecturer at The University of Sydney teaching biomedical devices and instrumentation

Alistair did his PhD at Oxford and was a Research Fellow at University College London, Marie Curie Research Fellow at Philips Research. 

Alistair is an expert in prototyping and developing medical devices.

If I was looking to prototype a medical device he is probably the first guy I would turn to.

I met Alistair a few years ago when he had a team in the Sydney University INCUBATE startup accelerator and he is constantly developing new equipment to measure parts of the body.

Alistair talks about the brain and how his new equipment uses Electrical Impedance Tomography which measures electrical conductivity, permittivity, and impedance to map out structures in the brain, he also talks about the devices he has built in partnership with the Gates Foundation.
