Engineering. Her research in electronics test technologies
has led to the proposal of several new testing standards and
methodologies for the semiconductor industry. In addition, she has also proposed new measurement uncertainty
theories and frameworks with application to medical measurement, structural and mechanical systems. Her work is
adopted as a part of the South African National Accreditation System guidelines document TG 50-02. Dr. Ooi is the
youngest female fellow elected by the Institution of Engineering and Technology, U.K., a member of the IEEE Public
Visibility Committee and an ADCOM member of the IEEE
Instrumentation and Measurement Society.

with the ultimate aim of improving the quality and consistency of plant-based products. In particular to the healthcare
industry, this will hopefully be one of many technological solutions towards increasing the global life expectancy, health
and well-being.

Gregor Steinhorn (gsteinhorn@unitec.ac.nz) is a Biotechnologist and industry-academic collaboration expert. After years
researching for Comvita the immune effect of components in
New Zealand ma¯nuka honey used for wound treatment with
medical honey products, he became Unitec Institute of Technology's Research Partner focused on enterprise building and
facilitating research collaborations between academics and industry partners. In this role, he has supported the project to
build the first New Zealand designed hydrogen fuel cell vehicle at Unitec and the formation of an international research
network around Unitec's Environmental Solutions Research
Centre conducting world-leading research in the field of bioremediation of asbestos contaminated soil.
Manu Caddie (manu.caddie@ruabio.com) is Kaihautu-Innovation and Regulation at Rua Bioscience, having stepped away
from the Chief Executive role in early 2020, and is one of New
Zealand's most trusted authorities on medicinal cannabis. Kaihautu is a Maori term used traditionally for the navigator in
voyaging waka, the person responsible for identifying opportunities, a fitting title for Manu since he was the only cannabis
