My name is Kellie MacPhee, and I am a fifth-year Ph.D. student in the Mathematics Department at the University of Washington.

My academic interests are in optimization and variational analysis, with connections to data science and machine learning. I am also working towards the Advanced Data Science Option along with my Ph.D. In Summer 2018 I was a Data Science for Social Good Fellow at the University of Washington's eScience Institute, where I worked on a project exploring equity of access to summer educational resources.

As mentioned above, my research interests are in optimization and variational analysis. My Ph.D. advisor is Professor Dmitriy Drusvyatskiy. If you are interested in optimization at the UW, I encourage you to check out the interdepartmental TOPS and CORE seminars, as well as the Machine Learning and Theory group seminars in CSE.
