In Fall 2020, I was the lecture and lab instructor for the UBC MDS program’s DSCI 551: Descriptive Statistics and Probability for Data Science.

In 2017, 2018 and 2019, I was a teaching assistant for the UBC MDS program. UBC MDS courses for which I’ve been a TA include:

  • DSCI 551: Descriptive Statistics and Probability for Data Science
  • DSCI 542: Communication & Argumentation
  • DSCI 523: Data Wrangling
  • DSCI 552: Statistical Inference & Computation I
  • DSCI 513: Databases and Data Retrieval
  • DSCI 571: Supervised Learning I
  • DSCI 573: Feature and Model Selection
  • DSCI 563: Unsupervised Learning
  • DSCI 572: Supervised Learning II
  • DSCI 553: Statistical Inference and Computation II
  • DSCI 574: Spatial & Temporal Models
  • DSCI 554: Experimentation and Causal Inference
  • DSCI 525: Web and Cloud Computing
  • DSCI 575: Advanced Machine Learning

I was co-organizer and workshop TA for the 2017 BC Data Science workshop and 2018 BC Data Science Workshop.

Past TA duties include: ODEs, Vector Calculus, Calculus I and Mathematics for Biology.
