Research In Profile

Professor Angela Roberts holds a joint appointment in the School of Communication Sciences and Disorders and Department of Computer Science. She is also a speech-language pathologist. She is a founding Co-Director of 澳门六合彩开奖预测’s Collaborative Specialization in Machine Learning in Health and Biomedical Sciences and is a Research Associate with the Canadian Centre of Activity and Aging. She was on faculty at Northwestern University in Chicago, Illinois prior to moving her research program to 澳门六合彩开奖预测.

Her impactful research program improves cognitive aging outcomes through rigorously validating connected speech signatures that detect and monitor cognitive decline, building phenotypes and predictive models of cognitive aging trajectories (dementia to extraordinary cognitive aging), and developing dyadic interventions that address communication challenges experienced by persons with dementia and their families. Her clinical research program uses robust randomized control trial designs and telehealth service delivery systems that have a global reach. Her influence extends to health charity organizations as a research board member for Parkinson Canada and an author of internationally distributed patient and family education materials.

Professor Roberts’ work is funded by the Ontario Brain Institute, the Canadian Institutes of Health Research, and the National Institutes of Health (U.S.), including an early investigator award from the National Institutes of Deafness and Other Communication Disorders.

Graduate Student Opportunities

Potential Projects:

  • Developing/validating connected speech and language biomarkers of cognitive impairment.
  • Evaluation of treatment efficacy in a clinical trial of speech-language therapies for persons with primary progressive aphasia using traditional and technology-facilitates treatment outcomes focused on communication participation and caregiver burden.
  • Development and validation of novel treatment outcome measures and clinical trial endpoints in dementia and neurodegenerative brain diseases.
