Nicholas Dwork

I am very excited about advanced mathematics applied to medical technology. In particular, I am most interested in applications of optimization to medical imaging. Most of my research has focused on Magnetic Resonance Imaging (MRI); I have also worked on Optical Coherence Tomography (OCT) and other imaging technologies. Aside from research, I greatly enjoy teaching and do so regularly.
