Henrietta is a Research Fellow in the Mood Disorders Centre. Her research focuses on understanding repetitive negative thinking (RNT: rumination and worry), using experimental approaches to investigate what causes people to ruminate or worry, which factors influence whether RNT is more or less helpful, and possible exits to ruminating or worrying.

She is currently employed on two research council funded projects that focus on interventions to reduce RNT. The NIMH funded RuMeChange clinical trial (Principal Investigators Ed Watkins and Scott Langenecker) evaluates the effectiveness of rumination-focused cognitive behavioural therapy (RFCBT) as an intervention to reduce rumination in adolescents at increased risk of depression. The trial examines neural and behavioural mechanisms of rumination, and the potential for RFCBT to shift these. The Wellcome Trust funded project "Understanding the mechanisms driving the reduction of repetitive negative thought" (Principal Investigator at Exeter Ed Watkins) seeks to delineate the causal mechanisms that underpin reductions in RNT and what are the active ingredients in RFCBT that effectively manipulate these mechanisms, thereby reducing RNT.

Previous research projects that she has worked on include a clinical trial evaluating cognitive training for young people with acquired brain injury (Principal Investigator Anna Adlam), a proof-of-concept trial developing and evaluating a cognitive training intervention to reduce rumination in young people (co- Principal Investigator with Anna Adlam), and a cohort study of reward sensitivity and processing (Principal Investigator Barney Dunn). She worked as a Lecturer (Research Tutor) on the DClinPsy programme at Exeter from 2021-2023.
