Work

I am an engineer at Uppsala University in Sweden. My research interests include

  • wireless communication in control engineering,
  • energy harvesting and wireless energy transfer in control engineering applications,
  • scalability of dynamical systems,
  • control engineering and its applications,
  • stability and analysis of two-dimensional systems and
  • port-Hamiltonian systems.
