BS, Ph.D., Clarkson University

Bio

Nate received his Ph.D. in 2009 from Clarkson University in Mechanical Engineering. His research background is in hydrodynamic stability analysis (particularly absolute/convective instability classification) and the long-time behavior of dispersive waves in fluids. From 2010-2014, Nate was an NSF CI-TraCS Postdoctoral Fellow, splitting his time between the Chemical Engineering Department and the Center for Computational Research at SUNY Buffalo. As a post-doc, Nate helped create the method of asymptotic approximants, a re-summation technique used to analytically continue truncated and/or divergent series. Since joining RIT, Nate has partnered with his long-time collaborator and co-creator of asymptotic approximants, Steve Weinstein, to build a research group of students and faculty with the goal of progressing efforts in asymptotic analysis in general.

Teaching is an underlying theme in Nate's career. During the first two years of his Ph.D., Nate was an NSF G-K12 graduate teaching fellow, running weekly science and engineering lessons in K-12 classrooms across NY from the Adirondacks to the Bronx. During the last few years of his Ph.D., Nate was a full-time instructor in the Math Department at Clarkson University; In 2009, he won Clarkson's Outstanding Teaching Award for Graduate Students. Continuing on a path of teaching excellence at  RIT, Nate has won the 2017/2018 RIT Innovative Teaching with Technology Award, the 2017/2018 Richard and Virginia Eisenhart Provost's Award for Excellence in Teaching, and an Eisenhart Award for Outstanding Teaching (2020/2021).
