I have an American BCBA-D (Board Certified Behavior Analyst-Doctorate) and an IBA (International Behavioral Analyst) certificate.

I supervise ABA/ABT-Programs through in vivo, films and online contacts.

For many years I have worked as a supervisor for an American ABA company.

For 15 years I have taught at the National University of Singapore and coordinated a center for children with autism center. 

Recently I edited the practice series "Autism Concrete" and have published a second cartoon book with my daughter who is a graphic designer.

Before the pandemic I gave workshops and talks, especially focusing on behavioral problems, communication, social behavior and visual support.
