Research Interests

Research Interests: My research is an integration of Occupational Health Psychology and Quantitative Psychology. I focus on developing technology-based supportive interventions for reducing stress and preventing problem behaviors among young adults and employed individuals. I am specifically Interested in conceptual and methodological aspects relating to the development of adaptive interventions that are delivered via mobile devices and that provide support in real-time to people as they go about their daily lives.

Key words: Social Support, Work Stress, Employee Health and Well-Being, Adaptive Interventions, Just In Time Adaptive Interventions (JITAIs).
