Six researchers have been named to the 2016 highly cited researchers list

Each year, Thomson Reuters compiles a list of highly cited researchers which captures the top one per cent of researchers with global influence and impact. Six researchers from the Cumming School of Medicine have been named to the 2016 list.

Jean Addington, PhD, is a professor of psychiatry at the University of Calgary. She has worked as a researcher, clinician and educator concentrating on psychosis and schizophrenia for over 20 years. Focused on finding predictors and mechanisms of conversion to psychosis, she currently works with young adults and adolescents to determine whether symptoms can be predicted and treated prior to a full-blown psychotic episode.

Herman Barkema, PhD, is a professor in epidemiology of infectious diseases, Veterinary Medicine, and a professor in the Department of Community Health Sciences, Cumming School of Medicine, at the University of Calgary. He applies epidemiology to the prevention and control of mastitis and infectious diseases on dairy farms.

Dr. Glenda MacQueen is a professor of psychiatry at the University of Calgary and vice dean, Cumming School of Medicine. She studies factors that are associated with outcome in mood disorders, particularly following a first onset of illness. She also examines cognitive function, structural and functional brain changes and physical health in patients with unipolar or bipolar disorder.

Dr. Johann Pitout is a medical microbiologist and professor at the University of Calgary. He studies resistance to antimicrobial agents among gram-negative bacteria. The focus of his laboratory is on detection, characterization and molecular epidemiology of bacteria. His current research interests are in developing next generation sequencing techniques to investigate different clones of globally successful bacteria. 

Hude Quan, PhD, is a professor with the Department of Community Health Sciences at the University of Calgary. He is also the director of the World Health Organization Collaborating Centre in Classification, Terminology and Standards at the O’Brien Institute for Public Health. He is currently leading an international research group of health information called International Methodology Consortium for Coded Health Information. The group was created to develop, test and promote methodological advances for the applied use of coded health information with the aim of improving methods in health services research. 

Dr. Marcello Tonelli is the associate vice-president (research) in the Office of the Vice-President (Research), University of Calgary, and senior associate dean (health research) with the Cumming School of Medicine. Dr. Tonelli’s primary research focus is improving the care of people with chronic kidney disease and other chronic health conditions.

The Calvin, Phoebe and Joan Snyder Institute for Chronic Diseases was named in 2008 in honour of Joan Snyder and her parents, who she credits for teaching her the value of philanthropy. It is a group of more than 104 clinicians, clinician-scientists and basic scientists who are impacting and changing the lives of people suffering from chronic diseases, including sepsis, MRSA, cystic fibrosis, type-1 diabetes, inflammatory bowel disease, and chronic obstructive pulmonary disease.
