Ph.D. student channels her resilience into solutions

Katie (Masaryk) Malarkey ’04 (physics) uses her good days for good. It’s a simple ethos that guides her life.

As an undergraduate at RIT, the Windsor, N.Y., native balanced roles as a resident adviser, lead editor for Reporter magazine, and member of choir and a cappella groups. Her first act after graduation aligned with her major, working as a thin film coating engineer for Newport Corp.

“I used to tell people I made rainbows for a living,” Malarkey joked, reflecting on her five-year career creating diffraction gratings.

Despite her success, something wasn’t right. After years of daily migraines, overwhelming lethargy, and painful physical changes, Malarkey was diagnosed with acromegaly, a rare condition caused by a pituitary tumor that produces excess growth hormone.

She considers that day one of the best of her life because she finally received a diagnosis for all her mysterious symptoms.

After subsequent and ongoing years of treatment, including radiation and brain surgery, she adjusted her priorities.

“My time as an engineer taught me to think critically and solve intricate problems,” she said. “But my health struggles taught me the value of perspective. If you can find the little joy in every day, it makes life a beautiful experience.”

Malarkey returned to RIT to tackle complex environmental issues. As a Ph.D. student at Golisano Institute for Sustainability, her research focuses on agricultural plastics—a largely overlooked contributor to environmental pollution.

“We rely on plastics for so much of our food production, from mulch films and irrigation tubing to greenhouses and horticultural containers,” she explained. “Yet we don’t even know how much plastic is being used, let alone how to recycle the majority of it.”

Her study, funded by a $15 million National Science Foundation grant, provides a comprehensive quantification of plastics used annually in U.S. agriculture. Her work also aims to address the end-of-life challenges for these materials.

Many agricultural plastics, contaminated with dirt and organic matter, are nearly impossible to recycle and often end up in landfills. Their breakdown releases microplastics into soil and water, potentially entering the food chain.

Malarkey hopes to help identify and mitigate those obstacles to create circular economy solutions.

“Katie has what we call that ‘secret sauce,’” said Callie Babbitt, professor of sustainability and Malarkey’s research adviser. “She has the intellectual curiosity, creativity in her approach, and the grit to overcome obstacles. She’s balancing so much in her life, but you wouldn’t know it because she shows up every day with a positive attitude.”

That balance includes juggling her responsibilities as a mother of two children and her work in the community. She is co-president of Parenting Village, a Rochester-based nonprofit that offers free support to local caregivers and families and hosts an annual Family Fest that draws thousands.

To Malarkey, sustainability is more than policy—it’s about fostering relationships on every level.

She embraces it all with gratitude and determination. “Coming back to school at this stage of life isn’t easy,” she said. “But the support I’ve found at RIT and from my family has made all the difference.”
