# Postdocs

**Nick Boffi**

Nick will be a Courant Instructor starting in Fall 2021. He received his PhD in Applied Mathematics from Harvard University, working with Professors Chris Rycroft and Jean-Jacques Slotine (MIT). He has expertise in computational science and numerical methods, dynamical systems theory, machine learning, and optimization. He is currently interested in understanding how to reliably incorporate high-dimensional function approximators such as neural networks into classical approaches in computational mathematics.

**Silvia Espinosa**

Silvia Espinosa has been a Courant Instructor since September of 2019. She combines her passions for teaching and fusion research - the renewable, safe and clean energy of the Sun and other stars - with Prof. Antoine Cerfon. She earned her PhD with Prof. Peter Catto at MIT, where she stayed two more years doing postdoctoral research. She also has expertise in high performance computing (including parallel programming of GPU), nuclear and alternative energy, and computational fluid dynamics (especially turbulence and molecular dynamics).

**Charles Puelz**

Charles Puelz has been a Courant Instructor since September of 2018 working with Charles Peskin and Dave McQueen on heart modeling. Previously, he was a postdoc with Boyce Griffith in his Cardiovascular Modeling and Simulation Lab. His research interests are in mathematical physiology, modeling, and numerical methods for partial differential equations.

**Pejman Sanaei**

Pejman Sanaei was a Courant instructor Sept. 2017 - July 2019, working on mathematical modeling and simulation in the Applied Math Lab (AML). He will be an Assistant Professor in the Department of Mathematics at New York Institute of Technology starting September 2019. He has expertise in fluid mechanics, deterministic and stochastic approaches to mathematical modeling, tissue engineering, applications of mathematics to industry and in particular his dissertation topic was mathematical modeling of membrane filtration.

**Brennan Sprinkle**

Brennan Sprinkle has been a Courant Instructor since September of 2019, working with Aleksandar Donev on modelling and simulation of colloidal suspensions. He recently received his PhD under Prof. Neelesh Patankar where he worked on simulations of aquatic locomotion as well as active colloidal suspensions. His research interests are in soft matter physics, stochastic differential equations, fluid-structure dynamics, and numerical methods for partial differential equations.
