Teaching
I am involved in the iEarth Centre for Excellence in Education, a national consortium of earth science departments. I am the iEarth Education Chair at the Department of Earth Science and Leader of iEarth Focus Area 1, which aims to develop a new framework for transforming the higher education curriculum. The educational change process is also the subject of the PhD project of Dario Blumenschein.
I have developed and currently teach the following courses:
GEOV114 - Introduction to geobiology
GEOV302 - Data analysis in earth science
I am also involved in the following courses:
GEOV344 - Geobiology and evolution of life on Earth
BIO318 - Current geobiological topics
