I'm mostly involved in projects related to cognitive modeling. R, Python and MATLAB are my go-to languages, but I have a growing interest in Julia.
My CV, publications and all are available on my website: kiantefernandez.com
Here are some open-source projects I'm working on:
- jsPsych-ADO: Adaptive design optimization, entirely in the browser, for jsPsych experiments.
- otree-et: Webcam eye tracking inside oTree.
- webgazer-qualtrics: A drop-in Qualtrics extension that captures webcam-based gaze data inside any survey.
- Clawlific: Prolific, but for AI agents — a recruitment platform for studying machine behavior in the wild.
- CogArena: A benchmark that puts AI agents through online experiments and ranks them against human baselines.
- Survey Shield: Sends an AI agent through your survey and reports which bot-detection traps it hit, and which it slipped past.
- face-trait-transformer: Predicts perceived-trait ratings from a face image.
- masc: A package for simulating the Multi-Attribute Search and Choice model in R.
- Rhddmjags: Example hierarchical drift diffusion model (HDDM) code using JAGS and Stan in R.
- DBDAJulia: Translation of Doing Bayesian Data Analysis in Julia using Turing.jl.
- hmp: Python package for trial-by-trial detection of cognitive events in neural time series (EEG/MEG).
- SequentialSamplingModels.jl: An interface for simulating and evaluating sequential sampling models in Julia.
