Currently, the group interests are

• Asymptotically safe quantum gravity

• Tensor models, tensorial (group) field theories and their connection to asymptotic safety

• Unimodular quantum gravity

• Scalar-tensor theories and their quantization

• Gravity-matter systems

• The interplay between neutrino mass mechanisms and quantum gravity

• The Gribov problem in gauge theories (My Ph.D thesis was on this topic and you can find it here)

• The infrared behavior of correlation functions in Yang-Mills theories

You can find my list of publications here.
