🎓 Academic Background

May 2021 Ph.D. in Mathematics at NC State
Jan 2018 M.Sc. in Applied Mathematics at NC State
May 2016 B.Sc. in Mathematics at JMU

🔬 Research

I research nonsmooth optimization, splitting algorithms, machine learning, and monotone operator theory. My collaborators and I develop these tools to solve nonlinear problems in data science, signal/image/audio processing, and large-scale optimization.
