Profile Summary

I hold a PhD in Clinical Psychology with advanced training in research methodology and statistical analysis. Over the past 10 years, I have worked in academia with a strong focus on grant writing, conducting original research, mentoring graduate student projects (Master’s theses, dissertations, and conference posters), and teaching graduate-level courses in Statistics and Research Methods.

As a research consultant, I have helped graduate students complete dissertation projects, supported faculty in preparing data-driven grant proposals, and assisted research teams in producing publishable results using advanced statistical techniques. My quantitative expertise includes: 1. Longitudinal data analysis using latent and multilevel growth models 2. Structural equation modeling (SEM), including path analysis and cross-lagged panel models 3. Mediation and developmental-cascade modeling 4. Latent class and latent transition mixture modeling 5. Exploratory and confirmatory factor analysis, including moderated nonlinear factor analysis for integrative data analysis 6. Monte Carlo simulations for statistical power estimation I am highly proficient in Mplus, R, SAS, SPSS, and Excel. I specialize in helping researchers select, conduct, and clearly interpret advanced statistical analyses to support publication, grant applications, and dissertation projects.
