The QUT Centre for Data Science is celebrating its graduates. Meet Katie Buchhorn who just celebrated her graduation with a PhD!
What was your PhD in?
My PhD was in the field of statistics and machine learning, specifically focused on optimal data collection methodologies, otherwise known as Bayesian optimal design. I focused on environmental monitoring of river network systems.
How did you come to do a PhD on this?
I read a book about Bayesian statistics and got really inspired by the field. I knew that I wanted to learn more and that was the field I wanted to gain an expertise in. I found some work of Kerrie’s (Centre Director Kerrie Mengersen) online, and reached out – the rest was history.
Did things change along the way?
Yes, I pivoted about a year in. I came across an interesting graph based neural network model for anomaly detection. I wanted to broaden my study area to incorporate other techniques and other fields to address a much broader problem. In the third year a combined optimal data collection strategies with anomaly detection. It allowed us to be able to solve real world practical challenges associated with ‘in situ’ sensor data.
How was your PhD journey? Any surprises?
It was just a lot of learning! I have a background in theoretical maths so moving to statistics was a steep learning curve for me at the beginning.
Did you anything else at QUT besides your PhD?
Lots! TEDx talk, outreach, various RA jobs. I was BRAG (Bayesian Research & Analysis Group) co-chair for two years. Most recently, I ran a National Science Week event where I encouraged students to turn their future dreams into art. Each participant was given a copy of my book, “Wondrous Worlds”, thanks to a sponsorship from the Centre. We also did a field trip to the Herbert river in my first few months.
How was your experience with the Data Science Centre?
I felt so supported, and made the most beautiful friends to ride the highs and lows with on this very long journey. It was a dream come true to all graduate together. We had been talking about this moment over coffee for years.
What’s next – or what are you doing now?
My dream job involves social justice and data science – stay tuned!
Congratulations, Katie!
