Fingerprints on a Great Career

Magna Forensics

A big part of the team’s job is testing the quality and durability of automotive materials for components, such as bumpers and liftgates on electric vehicles, and recycled materials, including hemp, for exterior parts.

“The data we generate goes into simulation modeling software and helps to predict how the material will react in all kinds of circumstances,” Bahash said.

Devices in the pristine lab include a scanning electron microscope that can magnify objects up to 300,000 times to zoom in on a part and determine if a problem was due to sharp impact or fatigue. This failure analysis can help to solve recall issues and other concerns. Other machines mimic weather extremes to test how parts will hold up in various climates.

“The Magna version of CSI is studying a part, not a person,” Bahash said. “But the idea is the same.”

Manufacturing Mystery

The scientists can help solve “cases” at the divisions, too.

One of Šušnjar’s first assignments was to help a Magna division determine the source of a mysterious white residue on a red lid on the assembly line. Using Fourier Transform Infrared Spectroscopy (FTIR), a tool for identifying materials, she determined the substance was a dairy product, most likely powdered milk, that may have entered the plant through the air or on outside equipment used at other manufacturing sites. The concern caused no issues and was quickly resolved.

In addition to testing various formulations of a component by subjecting it to car wash solution, coolant and deet containing insect repellant, her lab work includes checking the moisture content of pellets made from household waste for use in vehicles to see if they are porous and may swell or break with use.

While earning a combined degree in forensic science and anthropology from the University of Windsor, Šušnjar completed a mandatory 2-week intensive training course in forensic science from the Ontario Police College (Aylmer, Ontario). The training included blood spatter pattern analysis, forensic photography, expert witness on trial, lifting fingerprints, tread marks, and footprints. Her credentials also include an internship in Detroit with the Bureau of Alcohol, Tobacco, Firearms and Explosives Bureau, a U.S. law enforcement agency.

“Forensics, by definition, is law and advocacy for people,” she said. “It’s about asking the right questions and presenting the evidence – the truth. At Magna, I am one of the contributors in advocating for Magna’s products and upholding its integrity so that the customer will be safe and satisfied with our product.”
