Side Projects

Android Applications Developed:

    • Yams: a stock market prediction app that makes use of support vector machines trained on historical stock movement patterns to predict future stock price fluctuations. This app was developed in collaboration with three team members as part of the hackathon event LA Hacks 2015, where Yams placed in the Top Ten Hacks. 
    • Mindfully: this is a meditation timer app that I have developed initially for my own personal use and then submitted to the 2nd Annual UCLA Code for the Mission Contest in 2015, and which is now published on the Google play store.
    • MoneyTrack: this is an app developed for personal use to help gauge and monitor personal finances in an intuitive and secure way, for those less comfortable with inputting online banking details.  

Matlab Applications Developed:

    • Biofeedback Game: I made use of a custom-built Galvanic Skin Response device that I built for use in my Rubber Hand Illusion study, that was ultimately published (see above), to devise a game aiming to train the conductance signal it measures to remain low, and thus to keep the mind calm and tranquil. 


UCLA Undergraduate Students Mentored:

  • 2014 - 2015: Daniel Lin
    • In collaboration with our faculty advisor Prof. Zili Liu, I supervised Daniel's year-long honors thesis project aimed at applying state-of-the-art machine learning techniques to brain imaging data.
    • He presented our work at the UCLA Psychology Undergraduate Research Conference, Stanford Undergraduate Psychology Conference, and the UCLA Cognitive Science Students Association.
  • 2012- 2014: Albert Chung
    • With our faculty advisor Prof. Ladan Shams, I supervised Albert's project investigating the relationship between tactile stimulation and threat response, results from which were ultimately published in our 2015 paper listed above.
