Projects

Aerospace

Analysis of Aviation Emissions Policies
  • Analysis of key stakeholders' roadmaps to hit 2050 emissions targets
  • Identification of revolutionary technologies to aid in meeting these goals
  • Created attainability and readiness metric to compare technologies
Jet Engine Cycle Analysis & Optimization
  • Off-design cycle analysis of a separate flow turbofan in NPSS

Computer Science

NASA Discovery 2: An NLP Driven Mission for Topic Generation from NASA Datasets
  • Wells Fargo Campus Analytics Challenge 2019 winner
  • Used Natural Language Processing to generate topics based on publicly available NASA dataset
  • The approach used extends beyond the popular LDA method to identify topics present in the data set descriptions.
  • Consequently, this method could be used to tag similar datasets or quantitatively determine the topical overlap.
Natural Language Processing (NLP) Semantris Solver
  • Uses a computer vision in combination with Merriam-Webster's Thesaurus API and an NLP model built from Google News data
  • Solves the Google Experiment Semantris
  • Revamped version of @pravj's project "semantris-solver" ,
Lifestyle Importance Weighted Carbon Footprint Reduction
  • Wells Fargo Campus Analytics Challenge 2018 winner
  • Built a machine learning model that recommends lifestyle changes to minimize carbon footprint without affecting life quality
  • Attended the 2019 Wells Fargo Analytics Summit to present to top level data wranglers
LoL Player Stats
  • Tool that returns numerous player stats from their League of Legends match history
  • Designed to be an introduction for data analysts in Esports
  • Utilizes Cassiopeia, a well-documented Python wrapper for the Riot API and provides clear use case examples
Positional Presence
  • Spent two days learning from scratch how to use the Riot Games API
  • Built a tool to determine the relative differences in role presence at an apex competitive level in the game League of Legends and compare across regions
  • Used statistical analysis to demonstrate the relative agency of each role and the difference in playstyles from regions ranging from North America to South Korea
