Research

My research interests

I am an Experimental Psychologist by training. I began with laboratory-based studies and gradually transitioned to examining the mechanisms underlying various psychosocial and behavioral patterns using ecological momentary assessment strategies.

I have three primary research areas. The first area involves studying substance use and related psychosocial and behavioral issues among justice-involved individuals. My goal is to identify transdiagnostic factors and mechanisms underlying substance use-related symptoms and to develop prevention and intervention strategies to address these issues.

The second area focuses on interpersonal dynamics and affective science. Here, my aim is to explore the interpersonal and affective aspects of individual mental and physical health within an ecological context.

The third area involves employing various research methodologies to address my research questions effectively.

The third area focuses on adopting various research methodologies to address my research questions. 

Substance use and related psychosocial and behavioral problems for justice-involved individuals

My primary research interests focus on the etiological factors and prevention and intervention strategies for justice-involved individuals with substance-related issues. I like Kenneth J. Sher's approach to describing substance use and substance use disorders. In general, I am interested in studying treatment processes and outcome variables. Recently, I have become particularly interested in data phenotyping of substance use and aim to develop a digitally-enabled, AI-informed strategy for providing personalized prevention and intervention strategies. I describe my research motto as revealing What, why, when, how, where, and who for the phenomenon of interest (by Rudyard Kipling).

Through my interaction with individuals attending jail-based programs and jail-diversion substance use treatment, I learned that people need specific tools to help them navigate difficult life situations. So, I started applying positive psychology principles (i.e., hope, resilience) in developing an intervention curriculum for justice-involved women. I am influenced by James Pennebaker's work on expressive writing and Jane Goodall's work on hope in developing the intervention materials.

Interpersonal and Affective aspects of human behaviors and related symptoms 

Keywords: Aggression, victimization, emotion differentiation and regulation, daily life

Most of my research in this area is intended to address three primary questions. First, what are the transdiagnostic factors or transdiagnostic risks underlying interpersonal dynamics? Second, how does the interplay of personality and affect impact interpersonal dynamics?  Third, how do interpersonal and affective aspects of human behaviors impact mental and physical healthå? An exemplar question is do people with high rejection sensitivity tend to avoid arguments during interpersonal conflict and how does that impact individual health? 

I am influenced by a few giants in psychology, such as Dr. Scott O. Lilienfeld and his colleagues, Dr. Emily Butler and her passion for research on emotions and interpersonal dynamics, and Dr. James Gross and his research on emotion regulation.

Methodology Interest

In general, I am interested in all types of advanced methodologies and have applied a few different types of methods in analyzing data and addressing research questions.  Here is a list of examples:

It is hard to capture my research interests in a short paragraph so I created a word cloud of keywords from my publications (as of July 2023).  Below you will find a carousel of word clouds presenting the top 100, 50, 30, and 10 keywords from my publications.
