Dr. Torelli specializes in corrosion science and other industrially relevant electrochemical processes. His expertise spans several fields including: failure analysis and proactive testing of implantable medical devices, corrosion assessment and prevention of utility company assets, and electrochemical issues related to consumer electronics. He has experience in general and localized corrosion, galvanic corrosion, fretting corrosion, sulfidation and carburization, corrosion under extreme environments including acidic and high temperature environments, and protective coatings. Much of his work has focused on the study and control of surface reactivity which governs material properties such as surface oxidation, dissolution, and passivation. Dr. Torelli has experience with corrosion testing and monitoring of numerous materials including stainless and galvanized steels, titanium, nitinol, cobalt-chromium, and precious metals such as silver, gold, and platinum.

Prior to joining Exponent Dr. Torelli conducted research in the fields of electrochemistry, materials science, and polymeric materials. He developed an expertise in various materials characterization techniques as well as electrochemical testing. As a National Science Foundation (NSF) Fellow at Caltech, he conducted research on the discovery of electrocatalysts capable of converting carbon dioxide into chemically useful products. Through this work he developed aqueous, non-aqueous, and high pressure CO2 reduction systems interfaced with various analytical techniques such as gas or liquid chromatography, mass spectroscopy, and nuclear magnetic resonance spectroscopy. In addition, Dr. Torelli has conducted research on electropolymer coatings, inorganic and organometallic compounds, nanoparticles, and semiconductor materials. He has worked with wafer applied materials to improve the reliability of microelectronic applications.
