Research
I study behavioral treatments for depression and the measurement that makes them testable. Three threads share one method: reproducible data work in R, so every number here regenerates from data, not from memory. The threads are a longitudinal thesis on mindfulness-based behavioral activation, a systematic review of trans behavioral health care outcomes, and EEG research on stress and cannabis.
Master’s Thesis
The effectiveness of a brief, mindfulness-based behavioral activation intervention for college students with depression. New Mexico Highlands University, M.S. Clinical/Counseling Psychology (2026). Advisor: Dr. David Pan.
| Question | Does a brief, outdoor mindfulness-based behavioral activation intervention reduce depressive symptoms in college students? |
| Design | Longitudinal; psychometrics and statistical analysis in R |
| Status | Complete, degree conferred 2026 |
| Advisor | Dr. David Pan |
The full analysis pipeline (cleaning, psychometrics, longitudinal models, and automated reporting in Quarto) regenerates every table and figure from raw data. A public synthetic/de-identified demo is in preparation; no participant data will ever be published.
Systematic Review
Changes in Desired Outcomes for Trans Behavioral Health Care, 1963–2022
with Dr. Thomas R. Brooks
A systematic review of how desired treatment outcomes for trans behavioral health care have changed across six decades, presented at the Southwest Psychological Association (2023) and the Rocky Mountain Psychological Association (2023).
EEG Research
Emotional Stroop, cannabis, and stress
Heflin lab, New Mexico Highlands University
EEG study of chronic cannabis use and stress responses on an emotional Stroop task. Acquired new EEG equipment; managed lab inventory and consumables.
Methods & Tools
- R: psychometrics, longitudinal analysis, visualization; reproducible reporting with Quarto
- Assessment: neuropsychological, cognitive, and intelligence testing in clinical intake and treatment-planning settings
- Survey & data: SPSS, Qualtrics
- EEG: acquisition and lab management (Heflin lab)
