Josua Grawitter, MSc

Lupe [1]

I am a doctoral student at IRTG 1524 [2] working with Prof. Dr. Holger Stark [3]. Here, I study photoresponsive fluid interfaces based on switchable surfactants and substrates. Previously, I have worked on colloidal dynamical density functional theory (DDFT) for active particles. Find me on Twitter [4], Github [5], arXiv.org [6], and ORCiD [7]. My current research interests are:

  • photoresponsive surfactants, light-driven microfluidic devices
  • nonlocal diffusion-advection-reaction equations
  • control methods for soft matter systems; feedback control
