Research Associate

Stanford University
  • Achievements: Discovered previously undetected biases in human decision making by applying novel probabilistic models. Pioneered understanding how humans adapt their unconscious decision biases. Presented data analysis results at Stanford and published in international journals.
  • Led project to build probabilistic models to predict human behavior and correct for their decision making errors
  • Used regularized logistic regression (L1 & L2) for variable selection and overfitting prevention  
  • Employed multivariate linear regression for performance assessment
  • Utilized unsupervised learning (k-means) to cluster response times
  • Validated and selected models using log-likelihood testing, cross-validation and information-theoretic approach
  • Extensively used parametric and non-parametric statistics
  • Wrote R package for modeling, simulation and data analysis of human decision making errors (
