Mark is a River Scientist. He loves rivers and catchments and during his undergraduate years he realised he wanted to work with rivers for ever (or at least a long time). Luckily for Mark and 2rog the dream was realised. Mark has been a river scientist in government, university and consulting for over 18 years now. He has been involved in research, teaching and consulting. Mark really wants to help make our rivers and catchments healthy and productive.
