Dave was a full-time professor in the School of Fire Protection Engineering Technology at Seneca College in Toronto Canada. He retired from Seneca at the end of 2014. He began using fire models in 1995 with FPEtool and progressed through CFAST and Branzfire, and on to Fire Dynamics Simulator. He designed and developed fire and evacuation modelling courses for full-time students in the Fire Protection Technology Program.
In 2000, he created the first online support forum for FDS, which ran until NIST created their own forum. Dave is a frequent contributor to the FDS Discussion Group. He is included in Acknowledgement section of both the FDS and Smokeview manuals. He has been offering a distance education course on FDS since 2003 that has been taken by an international audience of fire protection engineers. He has delivered 2-day workshops on FDS in Australia, England, Canada, Ireland, Lithuania, New Zealand, Norway, USA, and Venezuela. The furthest Dave has travelled to put on a workshop is Perth Australia. You can't get much further than that from Toronto!
Since retiring from Seneca he has been conducting training workshops for Thunderhead Engineering on FDS/PyroSim and Pathfinder
He works as a consultant in fire and evacution modelling for a variety of international and domestic clients.
