CyberGIS SPIN Intern

5/2015 - Present

  • Designed and developed a parallel program employed in CyberGIS Summer School on Big Data Landscapes
  • Tested performance of ROGER supercomputer through the portable batch system (PBS) with Intel benchmarks
  • Actively communicated and followed up with members of other NCSA departments to promote updating the cluster for further expansion of frameworks available to all ROGER users
  • Experimented on the Hadoop cluster with TeraSort and Starfish to adjust parameters for optimal performance
  • Prepared and demonstrated development results to an audience of more than 20 professionals of various areas

Projects

Identification and Localization of Siren Signals

3/2017 - 5/2017

  • Constructed a siren detecting architecture distinct from existing work using a fast singular vector model classification method, specifically non-negative matrix factorization (NMF) and support vector machines (SVM)
  • Trained a dimensionality reduction model using limited training data and performed localization with the returned set of general basis vectors
  • Experimented on simulated data and showed accurate estimation of ambulance location

Multitask Learning Accura-SEA on Stock Prices

10/2016 - 12/2016

  • Attempted to use historical stock price data to predict future directions through Multitask Learning
  • Studied the relationship between the number of tasks and the accuracy performance of Multitask Factorized Gradient Descent and other regressional algorithms
  • Evaluated the performance of each models through bootstrapping and meta-parameter selection using internal k-fold cross-validation

Champaign County Bikes CIGI Hack-a-Thon

12/2015 - 1/2016

  • Utilized dojo/request package to provide asynchronous requests to OSRM's viaroute API for retrieving the shortest path between given coordinates
  • Drew the route as a polyline with flags for beginning, middle, and end points using ARCGIS API's Graphic class

Urbanflow Web Application

12/2015 - 1/2016

  • Collaborated with 2 post-docs to create a prototype for a web application to show the movement of users within cities through analysis on Twitter data
  • Developed with ExtJS to create diverse panels with interactive grids for each user input category that responded by displaying plots drawn with D3.js or zooming into the extent of selected vector files using OpenLayers 2 library

Jenkins Plugin Extension

9/2015 - 12/2015

  • Worked in a team of 7 in a test driven development to extend an existing Jenkins Plugin, Test Results Analyzer, following XP methodology
  • Added more functionality such as comparing build results by selecting the checkboxes above build numbers and easing user navigation by displaying links to the results page

Eye Tracker Analysis

6/2015 - Present

  • Analyze .txt data files from Tobii software on 39 test subjects for eye position, duration, and response and create visuals using D3.js and Bokeh
  • Build interactive website for other researchers to explore the data and plots using Javascript/jQuery, HTML, CSS, PHP, and MySQL

Parallel Terrain Analysis and Predictive Mapping

5/2015 - 7/2015

  • Partitioned and distributed rows of the input image to number of processes desired by the user and calculated slope gradients in parallel through the Message Passing Interface (MPI) on HPC
  • Performed k-means clustering to create a terrain classifier with Apache Spark's MLlib (Machine Learning library) from information gathered through studying archival publications

Extra-Curriculars

Association of Data Science and Analytics

UIUC

Vice President and Workshops Lead

8/2014 - 12/2015

  • Presented project ideas and discuss in a group for possible extensions and improvements
  • Discussed with company representatives for collaborations for technical workshops
  • Led a group of 8 in the workshops committee to finalize details on the organization website and organize workshops
