Dr. Chandran is a rheumatologist and clinician-scientist affiliated with the Schroeder Arthritis Institute, and the Departments of Medicine, Laboratory Medicine and Pathobiology and the Institute of Medical Science, University of Toronto. He holds an MD/PhD with specialties in internal medicine, immunology, rheumatology and genetic epidemiology.

Dr. Chandran currently serves as the Co-Director of the Psoriatic Arthritis Research Program at the University Health Network. His research interests focus on the development of biomarker-based strategies to improve early diagnosis and prognosis of psoriatic disease (PsD; psoriasis and psoriatic arthritis [PsA]), as well as identify novel treatment targets through proteomics and mechanistic studies and strategies to reduce its impact on society. 

Dr. Chandran’s research has been supported by grants from the Canadian Institutes of Health Research (CIHR), The Arthritis Society, the Krembil Foundation, the Arthritis Research Foundation, and the National Psoriasis Foundation. He has published extensively (>200 articles) on genetics/genomics/proteomics and clinical aspects of psoriatic disease classification, and his H-index is 59 (Google Scholar).

Research Synopsis

Dr. Chandran’s scientific expertise is in the genetic and molecular epidemiology of psoriatic disease (PsD; psoriasis and psoriatic arthritis [PsA]). This lifelong disease strikes patients in their youth, and is currently incurable, leading to progressive joint damage, functional limitation, poor mental health, reduced quality of life, and increased mortality. His translational research program focuses on understanding PsD pathobiology with particular emphasis on untargeted global discovery of novel biomarkers and drug targets using high throughput and augmented intelligence technologies.

His main goal is the improved and personalized management of PsD by:

  1. aiming at early diagnosis of PsA;
  2. identifying patients with psoriasis at high risk of developing PsA and developing interventions to intercept this transition;
  3. identifying subjects with PsA at high risk of developing arthritis mutilans; and
  4. developing drug or other interventions to treat the estimated 40% of PsA patients not responding to current therapy.

Dr. Chandran is currently looking for graduate trainees (PhD/MSc) for the following projects:

  1. Metabolomics of psoriatic disease in order to identify metabolomic markers for diagnosis, stratification, and treatment response.
  2. Integrated omics coupled with machine learning to develop a psoriatic disease data integration portal.
