Co-Founder and Chief Scientist

Dr Judy Bragger is a founding director of Quantec Ltd and leads the research into the properties and commercial applications of natural bioactives.

She has extensive research experience in biochemistry and microbiology, having worked for more than 12 years at the University of Waikato studying thermophilic organisms isolated from hot springs for thermostable enzymes useful for commercial applications, and working on a collaborative project with research groups at Fonterra Research, Massey University and IRL to identify the source of the thermophilic organisms in milk powders, and the effects of the enzymes from these organisms on milk powder.

Prior to that her work at the National Health Institute in Wellington included the isolation and identification of the pathogenic leptospires responsible for the disease Leptospirosis in farm workers in New Zealand, in collaboration with researchers at Monash University, Melbourne, Australia and the establishment of a Biological Standards Laboratory to perform biological tests to ensure that antibiotic preparations marketed in New Zealand complied with pharmaceutical standards.

Judy has a D.Phil from Waikato University, completed in 1990.
