Research case studies

Each study is documented from research question through recommendation — including the messy middle.

01
Quantitative Mediation analysis n=538 Cross-cultural

03
Secondary data analysis R · ggplot2 n=6,844 Gaming behavior

04
Research-through-design Experience sampling R · lme4 Pre-registered (OSF)

Driftline — Screen Time & Wellbeing

A self-initiated, pre-registered experience-sampling study testing whether how people appraise their screen time predicts wellbeing better than how much they use — with a working prototype and a validated R analysis pipeline.

About

Psychology background, product mindset

I'm a mixed-methods UX researcher with an M.A. in Psychology from Hunter College, CUNY (GPA 3.96) and a first-class B.Sc. from the University of the West Indies. My training is in social and quantitative psychology — which means I know how to form a precise research question, design an instrument to answer it, and analyze the results rigorously.

My thesis was a 538-person survey study using regression and mediation analysis in SPSS to examine how psychological traits shape fear of crime across ethnic groups in Trinidad and Tobago. The most important finding wasn't the one I expected — and that's what makes it interesting.

I'm drawn to UX research because it applies the same toolkit — study design, behavioral data, mixed methods — to questions that directly shape what people experience. I'm particularly interested in how people engage with digital products, what drives their decisions, and how research can move organizations to act differently.

Outside of research, I'm deeply embedded in gaming and digital media culture — which informs how I think about user behavior, community dynamics, and engagement at companies building products people genuinely love.
