Data

It was an ongoing project of mine to develop a forecasting model for elections in Australia called Emma Chisit. I made a number of posts on this website about the pitfalls and difficulties of coming up with such a model (starting here). I haven’t found a lot of time for the project recently but hope to return to it someday.
I wrote a trendy scraper for Google trends which gives daily data for queries across long timescales (Google trends only outputs weekly data for periods longer than a few months). See the post here, or see the updated code in the Github repo.
My blog contains a bunch of posts about data and data science:
- Here I quantify how much of a Pitchfork sychophant I am (not as much as I thought).
- Starting here I do some sentiment analysis of Twitter data for tweets posted during the broadcast of an Australian political panel show infamous for its lively Twitter feed.
- Here I wrote a tongue-in-cheek game to demonstrate the safety of air travel.
- Here I play with an unbalanced Kaggle dataset on credit card fraud.
- Here, here and here are some more mathematically-inclined posts about the theory behind some common machine learning / data science concepts.

My PhD thesis, submitted in 2014, was titled Alternating quiver Hecke algebras. It consisted of a careful and complete study of a new family of algebras, which generalise and build on important recent work. The main theorem of my thesis gives an explicit isomorphism between my new family of algebras and a family of classical objects which have been studied for over a century, providing new insight and structure for these objects. I wrote a FAQ about my PhD here.
You can find a list of my published mathematics papers here.
I ran the first-year linear algebra course MATH1002 for the University of Sydney Summer School in 2015. I took a much different approach to the course than in previous years, running the whole thing through a Wordpress blog.

I’m a keen amateur (very) photographer: all over this website you can find examples of my photographs taken all over the world.
Here I made a simple Python application which reminds busy expats to call their mums.
I very much enjoy jogging, particularly new places I haven’t explored yet.
