About Me

I am Postdoctoral Research Associate (since September 2019) in the Wisconsin Institute for Discovery at the University of Wisconsin-Madison, working with Steve Wright. In July 2020, I will join the Discipline of Business Analytics at the University of Sydney Business School.

My research focused data-driven optimization models and scalable algorithms for decision making problems under uncertainty.

In May 2019, I completed my PhD at the Tepper School of Business, Carnegie Mellon University. I was very fortunate to be advised by Fatma Kılınç-Karzan. You can find a copy of my dissertation here.

In 2013, I completed my undergraduate degree in mathematics at the Australian National University.

You can find my CV here and email here.


I use techniques from large-scale optimization, machine learning and statistics to better understand the challenges and capabilities of decision making models under uncertainty.
I have also worked on the application a variety of optimization tools to choice modelling, portfolio optimization, electronic trading, and solution design of IT services.
