Mauricio D. Sacchi was born and raised in Coronel Brandsen (Buenos Aires), Argentina. He received a Diploma in Geophysics from The National University of La Plata, Argentina, in 1988 and a PhD in Geophysics from UBC, Canada, in 1996. He joined the Department of Physics at the University of Alberta in 1997. His research interests are in the area of signal analysis and imaging methods. He directs the Signal Analysis and Imaging Group, an Industry sponsored initiative for advanced research in signal processing and imaging. He has developed and taught short courses for the industry and for the CSEG and EAGE societies in the area of seismic signal theory, transform methods for signal enhancement and seismic inversion. With Tad Ulrych he wrote the book "Information-based processing and inversion with applications" published by Elsevier. Mauricio is a member of the CGU, CSEG, EAGE, IEEE and SEG societies.
