Remembering Lauren Mueller: Engineering A Legacy of Empathy
Lauren Mueller, ChE ‘16, decided to be a chemical engineer when she was eight years old. Her father, Alan Mueller, a chemical engineer, and her mother, Vicki Mueller, a geological engineer, inspired her early—and technical thinking became second nature in a family where even her younger sister, Kalie, also became an engineer.
“From a young age, she was motivated by the challenge,” said her husband, Tyler Fedrizzi. “Listening to her dad talk through the complex chemical engineering problems built momentum for her to choose her path. Once she made up her mind, there was no stopping her.”
A cold campus, a warm heart
Born in coastal Ventura, California, after spending high school sweltering in Brisbane, Australia—where classrooms lacked air conditioning—Lauren only applied to colleges where it snows. “She was done with the heat,” her mother laughed. Top rankings helped her choose the University of Minnesota’s chemical engineering program.
“She wanted to go to the best school and study the hardest major,” Fedrizzi said. “That was one of the first things that impressed me about her.”
Mueller dove into her studies with grit and humility, minored in computer science, and never missed a home football game. “She talked about how cold it was and didn’t wear gloves and loved it,” her husband recalled. Her experience at the University of Minnesota left a lasting mark. She proudly collected bumper stickers, pins, and memories along the way.
She joined the Society of Women Engineers, drawn to a community that understood the challenge of being a woman in engineering. “She was passionate about making it normal—not rare—to see women leading in these spaces,” said Fedrizzi. Lauren stayed involved after college, attending events, advancing hiring efforts, and mentoring women throughout her career.
Lessons that shaped her career
Mueller’s defining academic experience was the capstone “Unit Operations” lab, taught by Chemical Engineering Professor Raul Caretta, ChE Ph.D., ‘79. He used the Socratic method, answering every question with more questions, and didn’t provide the answer. “It was not something students loved,” Caretta admitted, “but it made them learn how to think.”
“She was intimidated at first,” her mother said. “But she came away with real respect for the course and Professor Caretta.”
“Lauren was a very dedicated student, driven not just to learn—but to learn how to learn, ask the right questions, and solve problems,” Caretta recalled.
That mindset—the process of thinking through the unknown—became central to her work.

A professional life of impact
After graduation, Mueller took on a demanding Cargill plant operations role in Fayetteville, North Carolina, managing a 24/7 team. Her technical skills stood out, but her empathy made her exceptional. “She respected the operators, and they respected her right back,” her mother said. “And that’s often rare.”
While in North Carolina, Mueller met the love of her life, Fedrizzi, who was stationed nearby with the Army. When he pursued his electrical engineering degree in Indiana, Lauren supported his transition and worked remotely for Cargill. “I wouldn’t have made it through the program without her encouragement and tutoring,” Fedrizzi said.
She later became a Cargill process optimization engineer, her dream role. “It was the collaboration she valued most,” her husband said. “That’s what energized her—solving hard problems with her colleagues, together.”
Mueller continued to earn deep respect. “Her enthusiasm and positive attitude were contagious, and her ability to take on new things and deliver them to perfection was second to none,” said Lauren’s manager Akshaya Rai, the Senior Director of Manufacturing Technology and Value engineering at Cargill.
“People naturally gravitated toward the high standards she held for herself,” said Fedrizzi. “But she was also very kind, very empathetic. She was always willing to listen. People respected that about her. That’s what made her so special at work—and in life,” he continued.

A love of life, too
Outside of work, Mueller brought the same positivity and dedication, pouring herself into the things she loved.
She was an accomplished cook and baker, approaching it with the same precision as a chemical engineer. “She had spreadsheets for conversions, measured everything in grams,” Fedrizzi said. “There was always something being baked.”

Mueller adored her family, which included her rescue dogs, and loved gardening, hiking, and organizing plans down to the minute. She had an adventurous spirit, volunteered in Cambodia, and loved to travel with her family.

A scholarship legacy built on purpose
Mueller passed away suddenly on March 10, 2024, at age 29 from a pulmonary embolism, likely caused by an undiagnosed genetic clotting risk combined with a medication interaction. Fedrizzi now shares her story in hopes of helping others: “Be careful of the medications you take, he said. “Know your risk factors. Ask questions. There’s genetic testing now that could save your life—or someone else’s.”
Soon after, Lauren’s parents, her husband, and her father-in-law, Rick Fedrizzi, established the Lauren Mueller Memorial Scholarship to support CEMS students who share her passion for advancing women in engineering.
“We were fortunate to afford college,” her mother said. “Our daughters never had to worry about tuition or working while in college. Lauren would have loved helping someone else who needed that support.”
Fedrizzi added, “It’s critical that this endowed scholarship lasts and continues to grow so we can support more people and continue the work she cared about most.”
He hopes every student who receives the scholarship understands Lauren’s mindset. “It doesn’t matter how hard things get—when you fail, or when things aren’t going your way—as long as you’ve tried every possible avenue with your full effort, you’ve already succeeded,” said Fedrizzi. “That’s what she believed and lived. And that’s what she would want others to know.”
That spirit lives on in the students the scholarship supports.
“Receiving the Lauren Mueller Memorial Scholarship is an incredible honor,” said Raji Vijayan, the 2024-25 recipient. “Her legacy inspires me to keep pushing forward. Because of her, I had access to research and mentorship that enriched my experience and shaped my goals. I want to carry forward her example by contributing to a more inclusive and innovative engineering field.”
This scholarship, said Fedrizzi, is a way “for a part of Lauren to continue living in the world. It helps me feel like her impact is still being felt, even if she’s no longer here.”
