Welcome! We are a lab interested in all things squishy and biomechanics related from The College of New Jersey (TCNJ), led by Nick Battista, an assistant professor in the Mathematics and Statistics Department.

Our central research focus currently is unraveling the swimming performance of a variety of marine invertebrates and pushing their modes of locomotion to their absolute limits (no critters are harmed in our computational models); however, we investigate many other interesting phenomena in biomechanics, math physiology, and fluid-structure interactions. 

Nick is the creator and main contributor of a various numerical tools for research, teaching, and recreational purposes, which are available on his GitHub site. In particular we primarily use his software package, IB2d, for studying fluid-structure interaction problems, which allows for a robust construction of an immersed boundary. 


A recent focus of our lab is studying the limitations of different swimming strategies using a blend of computational fluid dynamics models and organismal experiments. We are fortunate that TCNJ has its own HPC (ELSA) in which we use to perform our widespread locomotion studies.

Part of our research has been developing computational tools that help decrease the learning curve for students and scientists, who have minimal programming experience, to perform fluid-structure interaction models and other CFD simulations at an accelerated rate.

  • Tierney Baldwin's, Rose Pereira's, and Zain Moin's ELSA (HPC) usage by in 2020 for fluid-structure interaction simulations:


  • Tierney Baldwin and Zain Moin presented at SACNAS 2020Check out their  short teaser videos below! Congrats to Tierney and Zain for delivering great presentations!

  • Congrats to Mike Mongelli whose 1st first author manuscript was just accepted in Fluids! In this work, we studied the underlying fluid dynamics of pendulums, compared the results with the canonical reduced-order model of a damped pendulum, and discussed unsuspecting, interesting results! Here's the info:

  • Our work in which we provide a collection of open-source fluid solver codes (each with numerous built-in examples) to the scientific community has been published. Here's the info:
