Arnold Mathijssen

Arnold JTM Mathijssen

Assistant Professor

Department of Physics & Astronomy

University of Pennsylvania

Arnold enjoys exploring the physics of life. Before starting the lab, he completed his PhD in theoretical physics with Julia Yeomans FRS at the University Oxford, and his postdoc in bioengineering with Manu Prakash at Stanford University. Honours include being named “30 under 30” by Scientific American, the HFSP Cross-Disciplinary Fellowship, the Sir Sam Edwards PhD Thesis Prize, the APS Charles Kittel Award, the Kaufman Foundation Early Investigator Award, and the Klein Family Social Justice Award.

To make science more equitable and accessible, we started a series of outreach events about “Kitchen Science” for students from underrepresented backgrounds in Philadelphia. Arnold is also chair of the Conference for Undergraduate Women in Physics (CUWiP), to be held at UPenn in January 2024.

Postdocs

Ercag Pince

Albane Thery

Postdoc

Simons Foundation Postdoctoral Fellow

Albane is interested in building mathematical and numerical models for hydrodynamics problems that arise in soft active matter and biological physics. Specifically, she has been working on the influence of confinement on the large-scale patterns that emerge in suspensions of swimmers interacting through the fluid. She also wants to understand the interplay between the properties of complex fluids, and an organism swimming and sensing its surroundings. Although her work so far has been theoretical, she works in close collaboration with experimentalists to understand collective dynamics in assemblies of microswimmers as well as at the intracellular scale.

Before coming to Philadelphia in 2022, Albane did her PhD at the University of Cambridge under the supervision of Eric Lauga. When not in the lab, Albane can be found reading, cooking, and lifting (tentatively heavy) things at the gym.
