Areas of Research

Treatment Development Research, Clinical Symptomatology and Cognitive Functioning in Older Adults


My interests are in treatment development research aimed at improving emotional, cognitive, and functional outcomes in individuals with psychiatric illness and cognitive disorders. Specific interest areas include associations between clinical symptomatology and cognitive functioning in older adults, as well as in individuals with severe mental illness; the use of technology for fostering independence in older adults; and suicide prevention in individuals with complex psychiatric illness and cognitive disorders (e.g., PTSD/TBI, MCI, and schizophrenia).
