Dr Wallis is a professional research scientist with 30 years’ experience conducting clinical academic and pharmaceutical industry research. Establishing novel chromatographic methodology to reliably quantify drugs in diverse sample types is his speciality, with a strong background in applications for intensive care medicine. He has participated in approximately 100 pharmacokinetic studies for the pharma industry as either analyst, study director or manager. As a researcher at UQ he has over 130 publications, and in the last 15 years the AMO bioanalysis laboratory he manages has measured over 100 drug analytes, including more than 60 antimicrobials.
