She leads an internationally renowned therapeutic trials unit that has made major contributions to the development and licensing of around 20 novel therapies. She specialises in long-acting therapeutics and is global lead author for the FLAIR study which evaluated the first-ever long-acting injectable HIV therapy and was published in the NEJM. Chloe led the practice-changing blood-borne virus testing campaign Going Viral.

Her research focuses on inclusive study design and the ways of including and engaging women, pregnant women, racially minoritised people and older adults in clinical trials.

During mpox she established an international research collaboration (SHARE-net) that delivered four impactful clinical manuscripts which have changed international guidelines. She was an advisor to WHO Europe on mpox.
