My name is Courtney Paquette (nee Kempton) and I just received my Ph.D. from the University of Washington Mathematics Department (Aug. 2017). Currently, I am Ross Assistant Professor (Post Doctoral position) at Ohio State University. Starting in January 2018, I will be a post doc in the Industrial and Systems Engineering Department of Lehigh University. I will be co-advised by Prof. Katya Scheinberg , Prof. Frank E. Curtis , and Prof. Martin Takáč .

I study optimization, in particular continuous optimization and first order methods. My Ph.D advisor at the University of Washington was Prof. Dmitriy Drusvyatskiy.

Both UW and Lehigh University have strong optimization groups which spans across many departments: Math, Stats, CSE, EE, and ISE. If you are interested in optimization talks at either UW or Lehigh, check out the following seminars:

I study continuous optimization. My work has centered on various aspects of convex optimization with an emphasis on the continuous side, with connections to practical applications particularly machine learning. I work in variational analysis, a study which generalizes the concepts of differential analysis to functions that lack differentiability, but I also pursue research in first order algorithms to solve large sums of composition functions efficiently. My current work focuses on using first-order methods on structured non-convex and non-smooth problems.

You can view my CV here if you are interested in more details.

You can view my thesis titled: Structure and complexity in non-convex and nonsmooth optimization.


I have the following papers:
