“The acquisition of Kolby to the BiomeBank team comes at a critical time for the company, with a pipeline of products in development and a view to clinical trials in the US. Moreover, Kolby’s experience has been critical in spearheading BiomeBank’s move to a larger facility on North Terrace in Adelaide’s Health Precinct,” Prof Bryant said.

BiomeBank Chair, Christopher Hall, said, “The appointment of Kolby Day as Chief Operating Officer will further strengthen the company’s ability to successfully implement our strategies into daily operations in order to meet our objectives. This is particularly pertinent as we establish new GMP facilities in our North Terrace premises based in Adelaide.”
