Does anyone know a doctor in Angkor Children's Hospital?

Dear Cambodia Expat Community,

I'm a new member here, I was recommended to post my question here, and I hope someone can help:
I'm a paediatrician from Hungary, currently travelling a bit around SE Asia, and soon I'm visiting Cambodia.
As a doctor I'm very interested to know more about the health care in the countries I visit. As a pediatrician I became interested when I heard about the quality service of Angkor Children's Hospital and possibilities of volunteering there.
I'd like to have a contact person who is familiar with the system, let it be local or foreign volunteer doctor, with whom I could have a chat.
I know it is possible to visit Angkor Children's Hospital as a visitor to donate, etc., but knowing someone who works/volunteers there and has professional background info is for me more interesting if I consider applying in the future. )
I appreciate if you have any info.
Thanks a lot: 
Kinga
