Pittsburg State University graduate student Arifur Rahman has been making an impact in the world of materials science with his innovative research that transforms an everyday resource, milk, into a tool for healing. His passion for sustainability and biomedical innovation recently earned him national recognition, placing second in the Herman & Myrtle Goldstein Graduate Student Paper Competition at the AATCC & SEAMS Conference in Savannah, Georgia.
Rahman’s work focuses on creating biocompatible composite fibers made from lactose derived from milk, blended with stearyl glycyrrhizinate, a compound from licorice known for its antimicrobial properties. Using a method he calls the “Melt Centrifugal/Rotary Jet Spinning Concept,” Rahman produces ultra-fine fibers in a process similar to making cotton candy, heating the mixture until it melts and then spinning it rapidly, so it forms thin, solid fibers. The result is a safe, biodegradable material that can help prevent infections and promote wound healing.
“The idea came from thinking differently about what’s around us,” Rahman said. “Milk is something we all know, but lactose is biocompatible and safe for the human body. If we can make something useful from milk byproducts, we not only help patients, but also create value for the dairy industry.”
His project reflects his commitment to sustainability, an idea that began when he learned how traditional biomedical fibers often rely on synthetic polymers and harmful solvents.
“That made me want to find a more natural, affordable, and environmentally friendly option,” Rahman said.
Competing among students from major research institutions, Rahman stood out for his creative approach and clarity of purpose.
“It was humbling and motivating to win second place,” Rahman said. “What made it special was hearing Pittsburg State University being mentioned alongside top schools in this field. It showed that our work here can compete nationally.”
Behind his success stands a network of mentorship and collaboration. Rahman credits Dr. Mazeyar Parvinzadeh Gashti, his research advisor, for inspiring him to see science create real-world impact.
“Dr. Gashti has great ideas and always reminds us to think about how simple methods can improve people’s lives,” Rahman said.
Rahman also worked closely with Dr. Irene Zegar and Dr. Christopher Ward from PSU’s Chemistry and Biology departments, who supported him with microscopy and antimicrobial testing. He also acknowledged Syed Inayet Ali Shah, an exchange undergraduate student who contributed significantly to the project’s laboratory work.
“Their guidance helped refine my work,” Rahman said.
Rahman’s dedication extends beyond the lab. Balancing his role as a graduate research assistant with his coursework and personal life, he manages his time carefully.
“It’s definitely a balancing act,” Rahman said. “I set weekly goals and make sure to take time to recharge.”
The university’s support also played a crucial role in Rahman’s success. He received a student travel award from the Office of Research and Sponsored Programs, which helped him present his work in Savannah.
“PSU has been very supportive,” Rahman said. “The opportunities here have helped me grow as a researcher and build confidence in my ideas.”
Looking ahead, Rahman plans to continue refining his fiber-making process and expanding its antimicrobial potential. His goal is to publish his results in a scientific journal and one d
ay see his lactose fibers tested in clinical settings for wound dressing and drug delivery.
Rahman extended advice to other graduate students.
“Don’t be afraid to put your work out there,” Rahman said. “Even if it’s not perfect, presenting it helps you grow and gain confidence.”
