Dr Janice Ranson

Senior Research Fellow

 College House 

 

College House, University of Exeter, St Luke's Campus, Heavitree Road, Exeter, EX1 2LU, UK

Overview

Janice is a Senior Research Fellow and Deputy Director of the Deep Dementia Phenotyping (DEMON) Network, a global initiative supporting the application of data science and artificial intelligence to dementia research with over 1,500 innovators across 6 continents. Janice oversees strategic partnership development and manages the research activity of 7 multidisciplinary Working Groups, which focus on delivery of collaborative publications, funding applications and knowledge exchange.

A Fellow of the Royal Society for Public Health (FRSPH), Janice's scientific expertise includes development and validation of clinical prediction models, incorporating a wide range of clinical, biomarker and genetic features from large population-based cohorts and clinical datasets. Her work has included development of prognostic models for use in specialist settings such as the National Prion Disease Unit, screening tools for clinical trial recruitment, and prediction models for primary care, including a clinical decision support system for dementia identification in non-specialist settings (DECODE).

Within the University of Exeter, Janice's leadership roles include being the Institute of Data Science and Artificial Intelligence Theme Lead for Reproducibility, and Local Network Lead for the UK Reproducibility Network. 

International collaborations include invited membership of the NIH/NIA-funded Integrative Analysis of Longitudinal Studies of Aging (IALSA) initiative, and the European Task Force for Brain Health Services. Most recently, she co-founded a new Alan Turing Institute Interest Group in Precision Dementia Medicine, and a new Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART) Professional Interest Area in AI for Precision Dementia Medicine.

Prospective Students

I enjoy supporting early career researchers. I welcome enquiries from research students interested in brain health, prevention and diagnosis of dementia or related conditions, as well as those interested in working across disciplines. 

Qualifications

  • PhD Medical Studies, University of Exeter
  • MSc Psychological Research Methods (Distinction, Programme Prize and Dean's Commendation), University of Exeter
  • BSc Psychology (First Class), Royal Holloway, University of London
