About Me

I am a graduate student currently enrolled in the Data Science and Analytics program at the University of Calgary. My undergraduate degree is also from the University of Calgary, where I graduated in 2019 with a Bachelor of Science in Mathematics. I am fascinated by the way data science and machine learning apply mathematical and statistical principles to the real world in order to solve complex problems. In my personal life, I am an avid record collector and music and film enthusiast, and I have played drums both in the studio and live on stage around Calgary.

Personal Projects

Exploratory Data Analysis and Classification Algorithms on Insurance Claim Data

  • Cleaned, formatted, and stored car insurance claim data using NumPy and Pandas. Performed feature engineering to extract new information.
  • Used Matplotlib and Seaborn to create visualizations and explore trends in the data. Fit multiple classification models and tuned parameters to improve performance.
  • Final product is a ML model which takes in # of Demerit Points, Age, Car Crash Status, and Urbanicity and predicts with 75.35% accuracy whether a customer will make more than one insurance claim.

A Data Driven Exploration of Video Games — Sales and Scores

  • A data story in which I explore global sales of video games and their Metacritic ratings using data scraped from the web.
  • Generated insight about video game sales over time, the most popular video games and consoles, and how critic and user scores compare to a game's popularity.
  • Published in Analytics Vidhya on Medium.

Academic Projects

Multiple Regression Analysis of Canadian COVID-19 Data

  • Created a statistical model in R using COVID-19 and provincial health measures datasets.
  • Model predicts per capita COVID-19 infection rates using predictor variables like rural population percentage and prevalence of COPD and mood disorders.
  • Worked collaboratively with three teammates to formulate the project and present our findings.

Exploratory Data Analysis of Calgary's Traffic Data

  • Analyzed traffic trends in Calgary using data visualizations such as bar charts, treemaps, geospatial visualizations, and more with pandas, matplotlib, geopandas, and plotly.
  • Results could be meaningful for traffic control, policing, insurance, urban planning, municipal budgeting, driver education, medical and emergency services.
  • Worked collaboratively with two teammates to formulate the project and present our findings.
