Throughout the years, many of Canada’s and the World’s leading geophysicists have worked at Paterson, Grant & Watson Limited. Below is a short list of our most distinguished alumni.
Dr. Norman Paterson
Dr. Paterson was president of PGW since its inception in 1973 until his retirement in 1996.
Under Paterson’s presidency, PGW grew to become one of the largest non-petroleum geophysical consulting companies in the world.
In 1999, Dr. Paterson was inducted into the Canadian Mining Hall of Fame.
Dr. Fraser Grant
Fraser Grant (pictured right) was a founding member of PGW after many years teaching geophysics at the University of Toronto. He was the co-author, along with Gordon West, of the classic geophysics textbook Interpretation Theory in Applied Geophysics which has been used to teach thousands of geophysics students over the years.
Mr. Roger Watson
Roger Watson is the third founding member of PGW. After leaving PGW in 1984, he was a co-founder of Terraquest Ltd., an airborne geophysical survey company. He continues working as a consulting geophysicist.
Dr. D. James Misener
Jim joined PGW in 1975 and became president in 1996. He was instrumental in the creation of PGW’s multi-client, multi-country compilations. The result was continental scale magnetic maps of Africa, South America and China that could be used in regional exploration. Jim is a well-known interpreter of magnetic, radiometric and gravity data.
Dr. Colin Reeves and Mr. Ian MacLeod
Colin joined PGW in 1978. He became a director of the company and co-founder of Geosoft Inc. with Ian MacLeod. In 1983 he became a professor in exploration geophysics at the International Institute for Geo-Information Service and Earth Observation (ITC) in Delft, The Netherlands.
Ian MacLeod joined PGW in 1978 and with Colin, had the idea that microcomputers would become important to exploration geophysics. In 1986 they established Geosoft Inc., today an industry-leading Potential Fields/Geochemistry/GIS software system. In 2017 the Society of Exploration Geophysicists (SEG) honoured Ian with the Cecil Green Enterprise Award.
Dr. Hernan Ugalde
Hernan joined PGW’s Santiago office in 1997 and in 2001 he moved to Canada to pursue a Ph.D. at the University of Toronto, which he obtained in 2006. He was a postdoc with Bill Morris at McMaster University from 2006 to 2011, where he worked on 3D data integration while keeping his links to PGW as a part-time consulting geophysicist. In 2011 he returned full time to PGW, where he processed, interpreted and modelled geophysical data with a strong emphasis on obtaining geological information from various data types.
In 2016 he became Vice-President of PGW, and also an Adjunct Professor at Brock University, where he teaches geophysics and data integration.
