Dr Harriet Forbes


Assistant Professor

Keppel Street
United Kingdom

I am an epidemiologist with expertise in using electronic healthcare records. My undergraduate degree was in Human Sciences at Oxford University and in 2009 I came to LSHTM to complete an MSc in Epidemiology. Following the MSc I worked as a Research Assistant at the King's Centre for Military Health Research, investigating mental health outcomes among UK military personnel. I then completed a PhD at LSHTM, investigating risk factors for herpes zoster and postherpetic neuralgia using UK electronic healthcare records. I went on to complete a UKRI Innovation Fellowship from Health Data Research UK, on complications of herpes zoster.  Following this I worked at Bristol University using the CPRD Pregnancy Register to investigate the effects of anti-epileptic drug use during pregnancy on mother and baby.  I am now working in Professor Krishnan Bhaskarans group on the health and wellbeing of cancer survivors.
