My theoretical orientation is from a cognitive-behavioral therapeutic perspective, utilizing approaches such as Acceptance & Commitment Therapy, Cognitive Therapy, and Problem-Solving Therapy, as well as incorporating systems-oriented perspectives, where applicable. I follow the scientist-practitioner model of practice, emphasizing evidence-based clinical interventions and incorporating research endeavors into my clinical work.
I am a clinician at The Devereux Foundation, Whitlock Campus, working in a residential setting with individuals with intellectual/developmental disabilities and comorbid psychiatric and behavioral challenges. My work includes individual and group psychotherapy, applied behavioral analysis, psychological assessment, and facillitating growth-oriented activities in the therapeutic milieu.
In addition to my clinical interests in developmental disabilities, I also have strong interests in the areas of behavioral medicine, anxiety disorders, affective disorders, and sexual-offending behaviors. Previous clinical placements have included: primary-care clinical practice at University of Rochester (NY) Medical Center; organ transplantation assessment services at MCP Hahnemann Hospital; community mental health services in Walpole, MA; pediatric services, focusing on autism and elimination disorders, in Fall River, MA; and a college counseling center at Drexel University.
My major research interest is the manner in which psychiatric disorders and challenging behavior are expressed across the spectrum of intellectual disability. This is in the service of finding better-fit treatments for adults with intellectual disabilities and comorbid psychiatric diagnoses. My research aims focus on better understanding how psychopathology develops, manifests, and remits in this population and how we can tailor psychotherapeutic interventions to address these mental health needs for this specialized population.
I also have additional interests in chronic medical diseases and how individuals using coping to manage stress and prevent psychological distress. I have a particular focus on how people cope with the daily stressors of hemodialysis treatment for kidney failure, and potential intervention strategies to reduce the risk of psychological distress.
