BSc (Hons), CertMRCSLT
Senior Research Scientist

Louise is a certified member of the Royal College of Speech and Language Therapists (RCSLT), a member of the British Aphasiology Society (BAS) and registered with the UK Health & Care Professions Council (HCPC). Louise has 18 years of experience working in clinical research with 13 years of experience working in the Clinical Outcomes Assessment (COA) field.

Louise is experienced in both quantitative and qualitative research methods. She has experience in patient-reported outcome (PRO) instrument development, evaluation and interpretation using both traditional and Rasch Measurement Theory (RMT) psychometric methods.

Louise has led patient interviews (concept elicitation and cognitive debriefing interviews), patient and care-giver focus groups, and has experience in qualitative coding and analysis. At Modus Outcomes, she is involved with COA development, validation and troubleshooting across a range of clinical disciplines, applying mixed qualitative and quantitative methodology, as well as the conduct of literature reviews.

Before joining Modus Outcomes, Louise worked as a Research Fellow in Clinical Neurology and Health Measurement for the University of Plymouth, where she was involved in the conceptualisation, development and evaluation of PRO instruments in neurological disorders. Her experience in her previous posts as specialist speech and language therapist and senior researcher on the Plymouth Aphasia Study for Peninsula Medical School highlighted the crucial role played by outcome measures in clinical practice and clinical trials, and the requirement for rigorous, clinically meaningful methods of measuring the impacts of disease from the clinician, patient, and carer perspective. Louise is a co-author of several peer-reviewed publications related to COA evaluation.
