Huix-Rotllant’s homepage

I’m Miquel Huix-Rotllant, CNRS researcher. My expertise is in theoretical chemistry, especially focused on modeling photochemistry of photoactive proteins.



My current research focus on:

  • Development of QM/MM methodologies for excited states.
  • Energy dissipation in photoactive proteins.
  • Quantum dynamics of spin transitions in organic and organometallic complexes.

I’m currently working on the photochemistry of these two proteins:
