Creighton Heaukulani

I am a machine learning researcher at Goldman Sachs in Hong Kong.

We are always looking to hire talented machine learning practitioners into any of our major offices. Feel free to contact me for more information if you are interested:

My research interests are in probabilistic approaches to modeling and inference in all areas of modern statistics.

I completed my PhD in the Machine Learning Group at the University of Cambridge, under the supervision of Zoubin Ghahramani. I was previously supervised by Andrew R. Barron and Sekhar Tatikonda in the Statistics Department at Yale University.
