Summary

Research


My research interests focus on complex fluids and complex systems. Recent/ongoing projects include:

  • Linear and nonlinear stability of viscoelastic shear flows
  • Influence of superhydrophobic surfaces on channel flow of shear-thinning fluids
  • Classification of bots and analysis of their influence on Twitter
  • Waves and turbulence in simulated pedestrian motion
  • Abstract-based automated identification of multidisciplinary research

Teaching


I teach two classes in the Mathematics Department:

Network Science: a new elective for 2nd-year students

Scientific Computation: an elective for 3rd-year and masters students
