## Nick Battista – Mathematical Biology, Numerical Analysis

Assistant Professor of Mathematics

*Ph.D., University of North Carolina at Chapel Hill
*

** Research Interests** – Dr. Battista’s research lies at the intersection of mathematical modeling and scientific computing, where he specializes in the realm of biological fluid dynamics. He creates fluid-structure interaction models to better understand the role of blood flow in various stages of heart development, investigating the force distribution and morphogen gradients exerted by the blood flow, as well as, in turn, the effects of the heart’s complex morphologies on the flow profiles themselves. He also works on numerous other projects, such as aquatic locomotion and maneuverability, group behavior, and comparative biomechanics.

* Teaching Interests* – Dr. Battista has taught many introductory and advanced undergraduate courses, ranging from pre-calculus and calculus to numerical analysis, methods of applied math, and mathematical modeling. He has also mentored students from various scientific and engineering fields, such as math, biology, physics and mechanical engineering, on a variety of research projects.

## Cynthia Curtis – Knot Theory & Three-Dimensional Spaces

Professor of Mathematics

*Ph.D., Yale University*

** Research Interests** – Professor Curtis studies three-dimensional spaces (such as our universe) and knots. Interestingly, all three-dimensional spaces can be built from knots, so understanding knots and understanding 3-dimensional spaces are closely related. Most of her work involves trying to understand how we can recognize when two spaces or two knots are different from one another. (Imagine two different massively tangled shoe laces and ask yourself how you would know if they are tangled in exactly the same way!)

** Teaching Interests **– Most frequently, I teach multivariable calculus and various upper level courses in geometry and topology. I have also occasionally taught courses in algebra and number theory, and one semester I taught an FSP on the shape of the universe. Finally, I very much enjoy supervising undergraduate research projects, most commonly in knot theory.
