  • Analyzed growth in two-sided social platform, especially stack exchanges like Stack Overflow.
  • Brainstormed and developed models of growth of stack exchanges, and experimented with different models by applying various strategies, including Bayesian General Linear Models (GLM) and Robust Regression. Modified and applied Latent Dirichlet Allocation to generate topics. Observed connections between knowledge market models and certain economic models.
  • Analyzed how active ages of users would affect the growth of stack exchanges and modified the model with Leslie matrix and distribution of active ages.

  • Took part into development of “ZenVisage” project, a visual exploration system that provides users with visualization recommendations for interesting patterns from large datasets.
  • Developed and implemented various new algorithms to calculate discrepancies between multiple graphs, and to smooth graphs for better comparison results in similarity detection in the team in charge of interactive insight sketch interface.
  • Improved back-end and front-end work flow by modifying fundamental data structures in this application.
