Anna Heath
Anna HeathScientist
Anna is a Scientist at The Hospital for Sick Children (SickKids), Toronto, an Assistant Professor at University of Toronto and Honorary Research Fellow at University College London, UK. She is the Canada Research Chair in Statistical Trial Design. She holds a degree in Mathematics with French language from the University of Sheffield, UK and a PhD in Statistical Science from University College London. She moved to Toronto in 2018 to lead the development of innovative statistical methodology for four clinical trials for novel treatments in the paediatric emergency department. In 2020, she started as a Scientist at SickKids and founded the IMPaCT lab. Her research now focuses on developing novel statistical methodology, software, expertise and guidance to improve the efficiency and design of clinical trials, particularly in paediatrics. This research combines many areas including biostatistics, evidence synthesis, meta-analysis, Bayesian methods, decision theory, health economic modelling and simulation based methods. Outside of work, she is a very keen ballroom dancer, a musician and a cricket-lover.
