VP, EU/APAC Regional Lead of Quantitative Science, Global Lead of Certara’s Pediatric and Maternal Innovation Engine
Dr. Cheung has more than 20 years of experience in modeling and simulation, as well as clinical pharmacology, with expertise in PBPK/PD mechanistic modelling, special populations (e.g., pediatrics, maternal, and geriatrics), extrapolation, model-based meta-analysis, vaccines, infections, HIV, complex biologics, and different therapeutic areas across early, late-phase and post marketing drug development. She is an honorary professor at the School of Engineering at the University of Warwick, UK. She is leading the EU funding project, ERAMET (grant agreement number 101137141), in work package 5, championing the enhancement and utilization of extrapolation in pediatric populations and for rare diseases.
Before joining Certara, Amy was a Senior Pharmacometrician and Scientific and Project Leader at the AstraZeneca Pediatric Working Group, which included 22+ cross-functional pediatric experts. During this time, she also served as the company representative on the IMI DDMoRe initiative and co-led work packages (e.g., PMX-workflow, cardiovascular training) and IQ consortium CPLG Pediatric Working Group. Dr Cheung has been a member of the EFPIA MID3 workgroup since the 2011 EMA M&S workshop, which resulted in several white papers. Currently, she is contributing her expertise to various professional societies, such as the IQ Consortium, EFGCP, ASCPT, and EU Horizon-funded projects. She has published over 50 papers on MIDD methodology/applications, reviews, and white papers in peer-reviewed journals.
