Research and Clinical Interests

I am interested in (a) experimental psychopathology and psychological health in adult that has broader applicability to various forms of clinical and social issues and (b) the mechanisms of change in psychosocial interventions. I have been exploring and examining the impact of psychosocial factors, such as psychological acceptance and mindfulness, on clinical and social concerns, such as substance use problems, eating disorders, anxiety-spectrum disorders, and stigma. 

Given my multicultural background, diversity issues are also of great interest to me, particularly issues related to treatment utilization and treatment development in cross-cultural settings. 

In practice, I have exceptional training in mindfulness-based cognitive behavioral interventions, especially Acceptance and Commitment Therapy (ACT). My clinical experiences are broad with diverse clinical populations in a wide range of clinical settings, including university counseling center, outpatient clinic, residential home, and inpatient and outpatient medical hospital settings. Recently, I have been actively involved in therapist training, supervision, and treatment consultation.
