She has taught teachers at the graduate level for more than 20 years. She conducts a range of teacher training and professional development activities for teachers in South-East Asia and beyond. During her career, Marti has provided professional development and training for teachers in dozens of countries on 6 continents. Marti's doctoral studies focused on learning and change in human systems with special attention to how education can be transformational to both individuals and the groups they are part of. Marti is passionate about supporting teachers to do their best work no matter what context they work within. A prevailing interest is exploring what goes on "inside and between" people in education (Stevick 1980), and steadily moving towards a greater understanding of an inner and outer pedagogy of peace.
