When feedback becomes a learning signal.
A mixed-method study examining how timing and specificity of feedback influence persistence during difficult learning tasks.

01 / Inquiry before certainty
Make the
unknown
testable.
I investigate how people learn, decide, and adapt, combining experimental design, behavioral data, and transparent interpretation to turn hypotheses into useful evidence.

02 / Studies
Questions,
tested.
The portfolio is organized around the research arc: a sharp question, a defensible method, an interpretable result, and a clear implication.
Attention under interruption
Experimental work on task resumption, notification timing, and the hidden cost of switching contexts.
Memory, maps & mental models
Behavioral analysis of how visual structure changes recall and transfer when learners build spatial representations.
03 / Methods
Rigor with
human texture.
I favor methods that make claims inspectable: preregistration, transparent measures, thoughtful sampling, and analysis that stays close to the research question.
Experimental design
Controlled studies, counterbalancing, manipulation checks, and participant-centered protocols.
Behavioral analysis
Model-based reasoning, uncertainty-aware interpretation, and reproducible analysis workflows.
Mixed methods
Qualitative interviews paired with quantitative evidence to explain not only what changed, but why.
Experimental design
R / Python
Bayesian reasoning
Survey design
Qualitative coding
Open science
04 / Path
A trail of
questions.
Independent Researcher · Learning & Decision Lab
Leading collaborative studies on feedback, attention, and learning behavior; mentoring junior researchers and translating findings for education partners.
Postdoctoral Research Fellow · Human Learning Group
Designed behavioral experiments, developed analysis protocols, and contributed to multi-site research on cognitive adaptation.
PhD · Cognitive Science
Doctoral research focused on how learners update mental models when feedback conflicts with prior expectations.
Research Assistant · Behavioral Science Unit
Built participant protocols, supported longitudinal data collection, and developed an early interest in evidence communication.
05 / Contact
Bring a
good question.
I welcome research collaborations, academic partnerships, invited talks, study design conversations, and interdisciplinary projects where the question is still being shaped.
