My name is Sam Cogar, and I am a Ph.D. Candidate in the Applied Mathematics program at the University of Delaware. My advisors are David Colton and Peter Monk, and I began a three-year tenure as a National Defense Science and Engineering Graduate (NDSEG) Fellow in Fall 2016. I will begin a three-year Hill Assistant Professorship at Rutgers University-New Brunswick in Fall 2019 under the mentorship of Michael Vogelius. My CV may be found here: Curriculum Vitae.


I graduated from Marshall University in May 2015 with a B.S. in Mathematics/Applied Mathematics and a minor in Physics, and I received an M.S. in Applied Mathematics from the University of Delaware in May 2017. I will defend my dissertation entitled “New Eigenvalue Problems in Inverse Scattering” on March 12, and I plan to graduate with my Ph.D. in May 2019.

Research Interests

I am primarily interested in the study and application of eigenvalue problems in inverse scattering theory. For more information about my research experiences, see Research.


I am not teaching any courses in Spring 2019. For my previous teaching experiences, see Teaching.
