Irene always wondered why most conservatory and private vocal teachings aren't put into more concrete learning methods. And why, for university students, there is a possibility to conduct research by which they obtain a Phd or a Master's degree, but not for conservatory students. 
Traditional voice education, as the ones she had herself, is mainly founded on tradition, "hear-say" and personal opinions. But Irene thinks this should change. All teachings in whatever study field, should be based on real findings, as for example those by Ear-Nose-and-Throat and Lung doctors, Physiotherapists et cetera, and backed by medical proof. 

This is why Irene set out to conduct research for herself and she has been doing so since 2012.
In the belcanto era, there were many voice teachers, like Manuel García and Francesco Lamperti, that díd write their findings down. These findings and teachings were all checked with medical experts (Manuel García was not only a gifted voice teacher, but also invented the laringoscope, a medical tool used by voice doctors everywhere in the world). 
Nowadays, many voice teachers that create "a method", that some even call "complete", teach methods, that are not at all according to how our breathing system works, as Irene wil explain to you with proof, provided by lung doctors and other experts.

Irene teaches both in person in the Netherlands and Rome, as well as online around the world.
