Montie S. Avery

About Me

I am an NSF Postdoctoral Fellow at Boston University working with Margaret Beck. My research is focused on front dynamics and diffusive stability of coherent structures. I am broadly interested in pattern formation and dynamics of partial differential equations. I received my PhD from the University of Minnesota in June 2022, where my advisor was Arnd Scheel. 

I am co-organizing the Boston University Dynamical Systems Seminar together with Ryan Goh and Jonathan Jaquette.
