Chris TranquadaMASc PEng
Mr. Chris Tranquada is a project engineer in MEA Forensic’s Failure Analysis group. He assists with investigations of consumer product failures, water escapes and plumbing leaks, fuel oil escapes, wheel separations, and fires. Chris helps uncover the mechanisms and root causes of failure. “We make sure that we investigate thoroughly, consider all possibilities and are not satisfied until we have answers,” he says.
Chris has a Bachelor’s and Master’s degrees in Materials Engineering from the University of Toronto. His Master’s thesis focused on tiny water-repelling features found in certain tree leaves. “Knowing how to examine small-scale features helps me find important details when looking for the source of a fracture or failure,” he observes. A thorough analysis of the evidence will determine whether a failure was caused by deficiencies in design, manufacturing, installation, maintenance or use.
Chris enjoys using his expertise to help legal and insurance professionals unravel mysteries. “New questions come up all the time,” he says. “It keeps me on my toes.”

Project Engineer, 2015 to present
Conduct technical investigations of mechanical and material failures related to product, property, transportation, and equipment losses including water escapes, fuel oil escapes and fires. Employing scientific failure analysis tools to isolate root and contributing causes related to defective use, maintenance, inspections, manufacture, or design. Engineering work includes evidence and site examinations, non-destructive and destructive testing, statics and stress analysis, metallurgical analysis, and materials characterization for various metallic, plastic and composite components. Conduct routine experiments to test hypotheses of failure modes and failure sequences for components, products, and machinery relative to reported conditions or applicable standards and codes. Ongoing research involves metallography and scientific analysis (scanning electron microscopy, SEM/EDS).

Research Engineer/Physicist (EIT), 2014 to 2015
Aid in design changes for MRI guided High-Intensity Focused Ultrasound (HIFU) piezoelectric phased-array transducers currently under clinical development for non-invasive thermal ablation of cancer (bone metastases) and uterine fibroids. Conduct performance testing and general quality assurance of transducer modules and array using a radiation force balance to determine acoustic power output, and fiber optic hydrophone to determine array focusing ability. Execute individual experiments to determine methods of improving transducer acoustic power output, reliability and material performance through accelerated aging tests. Worked in various programming environments (C++, MATLAB, QtCreator and Ruby on Rails) and created databases.

Graduate Research Assistant (Master’s), 2011 to 2013
Member of the Nanomaterials Research Group in the Materials Department under the supervision of Professor Uwe Erb. Complete comprehensive characterization of superhydrophobic aspen and black locust leaf species with micro- and non-scale roughness that acts to effectively resist wetting (‘Lotus Effect’). Track evolution of their epicuticular wax morphologies (nano-scale crystals) over one full growing season using Scanning Electron Microscopy.Teaching Assistant, Faculty of Applied Science and Engineering, 2011 to 2012
Directed laboratory and tutorial sessions for first and fourth-year undergraduate courses (Introduction to Materials and Chemistry, Materials Selection II, Synthesis of Nanostructured Materials). Set and graded various assignments, quizzes and tests for the courses. Operated and directed laboratory experiments using Differential Scanning Calorimetry (DSC) for thermal testing and analysis of materials. Offered student help session meetings.
- MOUNT SINAI HOSPITAL
Research Assistant, 2010 to 2011
Undergraduate fourth-year thesis project, collaboration of University of Toronto Department of Materials Science and Mount Sinai Hospital Samuel Lunenfeld Research Institute in the Bone Biology laboratory under the supervision of supervisors Dr. Grynpas and Dr. Willett. The thesis involved testing bovine metatarsi samples (cut using a precision metallurgical saw) once incubated to form pentosidine and other biochemical markers characterized by the formation of Advanced Glycation End-Products (AGE’s) which can form in bone as a result of kidney failure, diabetes and the natural aging process. Performed various mechanical testing, including three-point bend testing and cyclic fatigue testing.
- MEA Forensic, 2015 to Present
Develop and implement field audit technique to estimate install torque of wheel fasteners for investigation of wheel separation cases.
- University of Toronto, 2011 to 2013
Executed research project and various laboratory experiments to characterize the development of micro- and nano-scale roughness asperities on superhydrophobic (extreme non-wetting) aspen and black locust leaf surfaces using analytical tools:
Hands-on use of various instruments including Scanning Electron Microscope (SEM) and Optical profilometer to characterize surfaces.
