Creighton Heaukulani

I have broad research and applied interests across machine learning and artificial intelligence.

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.

I was most recently a Vice President and Executive Director at Goldman Sachs in Hong Kong, where I worked to establish a machine learning team in the Securities division. If you are an ML practitioner considering roles in finance, feel free to get in touch if you have questions.
