Matt Sydes, Professor of Clinical Trials & Methodology

Matt is responsible for co-leading the unit's Trial Conduct Methodology programme with the Unit’s Director, Max Parmar. This work is to develop evidence-based ways to improve how clinical trials are run.

Particular areas of interest include: the use of routinely-collected electronic health records (EHR) to support and run trials, with Health Data Research UK; running academic-led trials with a view to regulatory use and submission; proportionate and efficient monitoring of clinical trial; implementation of novel designs into practice, particularly platform / master protocols; better clinical trial data sharing; and communication of trial findings.

Matt teaches on the UCL Institute of Clinical Trials and Methodology's MSc in Clinical Trials and supervises a number of PhD and MSc students. Matt leads UCL's short course on Data Monitoring Committees and has served on many IDMCs and TSCs for national and international trials.

Matt chairs the Scientific Committee for ICTMC 2022, the next International Clinical Trials and Methodology Conference, and is on the executive committee for the NIHR-MRC Trials Methodology Research Partnership (TMRP). He sits on several funding panels, including MRC’s Better Methods Better Research.

Starting in Spring 2021, Matt is 20% seconded to lead the Data-Enabled Trials theme for the BHF & HDR UK Data Science Centre.
