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.

  • Congratulations to Miruna Baciu who gave a fantastic talk titled, "To Toss Away or Not Toss Away" at the Spring 2021 MAA-NJ Meeting!

  • Tierney Baldwin's preprint for her first scientific paper is out: Hopscotching Jellyfish: combining different duty cycle kinematics can lead to enhanced swimming performance - Check it out!

  • Honored that one of our images was featured as the cover of SIAM Review Volume 63. It's from our manuscript "Fluid-Structure Interaction for the Classroom: Interpolations, Hearts, and Swimming!" that was in this issue! Check it out!

  • You can run this exact simulation (and the others from this manuscript) from our open-source immersed boundary software, IB2d -> here!

  • Simulations ran with MATLAB; data visualized in the open-source VisIt software

  • Other Valentine's Day related simulations created by our group can be found on this site here!

** Big thanks for Dr. Matt Mizuhara for making us aware of this! **



  • 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 presentation

  • Congratulations to Tierney Baldwin who gave a phenomenal Math & Stats Honors Thesis presentation. Tierney's thesis was titled "Sifting through Siphonophore Swimming: Studying Nectophore Offset Synchronizations
