About Me
I am a third year Computer Science PhD student at North Carolina State University. Working with Dr. Collin Lynch and Dr. Tiffany Barnes, at the Center for Educational Informatics, I'm currently modeling different student activities as a social graph and analyzing it. Generally we are trying to use educational data mining to identify useful behavioral patterns of students using online tools in CS courses. Eventually we want to find ways to help students perform better.
If my first hobby is reading novels, travelling is definitely the second one. I hope one day comes that I put a big map on my wall and fill it with marking the places I have visited. I like to know different cultures which makes the range of the books I read really wide, but I still think I need to travel and get to know people and see places to experience life better.

Projects
  • Riot Predictor
    • Data Driven Decision Making Course
    • Predicting how likely it is for a protest to turn into a riot based on the target of the protest, the issue, number of participants, crime rating in the area, and violence rating of the articles or social media posts. Information was extracted using natural language processing from articles on Bing and Duckduckgo, and another structured database.
    • Developed in Python, used machine learning methods such as neural networks, naive bayes, logistic regression, and random forest
    • Social Computing Course
    • Predicting number of retweets of a tweet, based on its links, hash-tags, mentions, author, etc.
    • Developed in Python and R, Using Snap, MASS, and Neural Networks
    • Course Project for Software Engineering | Spring 2016
    • Collected and analyzed GitHub activity data from 14 “Software Engineering Groups”, defined “Bad Smells” in these projects’ behaviors including their use of issues, milestones, commits and comments, and provided a case-study on them.
    • Built “Bad Smell” early detectors based on our definition
    • Developed in Python, practiced data collection, pre-processing, anonymization, feature extraction, and used z-score for finding outliers.
    • Software Engineering Course
    • Developed a helper tool for Github novice users. Provided them with a choice of commandline help, email bot, and search engine. Email bot and search engine used Stack-overflow search results, sorted by TF-IDF, while the commandline help used a decision tree. The product was also tested on novice users to find the best solution.
    • Developed in Python
