Originally from the Sudbury area, Eduard is a graduate of Laurentian's Engineering program (Extractive Metallurgical Engineering, 1993). He obtained M.A.Sc. (1997) and Ph.D. (2003) degrees from the University of British Columbia in the Department of Metals and Materials Engineering. In between his graduate degrees, and prior to joining the faculty of the Bharti School of Engineering, he worked for several years in both industrial research and operations.

Dr. Guerra's field of expertise can be broadly categorized as hydrometallurgy. He is primarily interested in reducing the energy requirements and environmental impacts of metal production. Currently, he is working on an alternative method to destroy cyanide from gold mill effluents using an electrolytic cell equipped with manganese dioxide coated anodes.  He recently supervised a Ph.D. project that led to the development (and patenting) of a technology to produce activated carbon coated polystyrene beads as an alternative gold cyanide adsorbent to pure activated carbon.  A great deal of this past research focussed largely on examining reusable solid catalysts to provide high reaction rates while reducing acid generation during pressure oxidation of sulfide minerals.  Another notable past project involved research into the use of a group of relatively nontoxic sulfur containing organics (often used as pharmaceuticals to treat heavy poisoning) to improve the performance of thiosulfate leaching of gold.
