about mhof

Publications

Since 2006, I have focused on research leadership, rather than individual research. As such, I have been less active in contributing individually to research papers, but instead focused on establishing strong research groups and helped them identify promising research topics and develop clever solutions. You will find many more publications with authors coming from my research teams.
