Bio

Nate received his Ph.D. in 2009 from Clarkson University in Mechanical Engineering, where he began his research on long-time behavior of dispersive waves in fluids. From 2010-2014, Nate was an NSF CI-TraCS Postdoctoral Fellow, hosted by Chemical Engineering Department and the Center for Computational Research at SUNY Buffalo. It was here that Nate and Steve Weinstein began developing methods for the re-summing divergent and slowly convergent series. Since joining RIT, Nate has partnered with Steve to build a research group of students and faculty with the goal of progressing efforts in asymptotic analysis in general. More info on their research group can be found here.  Their book "Power Series Solutions to Nonlinear Ordinary Differential Equations" can be found here: https://epubs.siam.org/doi/book/10.1137/1.9781611978544

Nate 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).
