Industrial waste, fragile supply chains and decarbonization targets rarely arrive one at a time. In a macroeconomic supply chain, choices made today inside one industry can cascade across suppliers, recyclers and regulators tomorrow. Traditional tools often treat these pieces in isolation, leaving decision makers without a unified view of how to design for true circularity. This fragmentation obscures feedback, delays investment and dulls accountability across value chains. Abhimanyu Raj Shekhar, a Bilsland Fellow and fifth-year PhD candidate in Purdue’s Department of Agricultural & Biological Engineering, is tackling those challenges together.

The continually expanding toolkit from Mohit Verma’s laboratory at Purdue University now includes a portable, paper-based biosensor for identifying genetically modified (GM) corn and soybean. The GM crop biosensor, based on a method called loop-mediated isothermal amplification (LAMP), offers a fast and less expensive alternative to the point-of-need molecular tools already on the market.

Purdue University and John Deere had been discussing opportunities to collaborate, and the development of an automated unloading system was the perfect chance to combine forces. Purdue didn’t just have technical expertise – the university also offered agricultural insight and the facilities to test emerging technologies in real-world conditions.

“Nearly 99% of the plastics produced today are made from petrochemicals derived from oil or gas, which often must be imported from outside the United States,” Sankaranarayanan said. “We want to take advantage of locally available materials, such as those commonly used throughout the state of Indiana.”

Six engineering majors were represented in the seventh cohort of Purdue Engineering Fellows, honored during a ceremony on Sept. 16 at Fowler Hall in West Lafayette.

Fellows were honored for their critical thinking and problem-solving skills, positive relationships with peers and contributions to the Purdue Engineering community.

Zhiyuan Chen is one of three Purdue University students that have been named by the Astronaut Scholarship Foundation (ASF) as 2025 Astronaut Scholars — one of the nation’s most prestigious merit-based scholarships for undergraduates in science, technology, engineering and math (STEM).

All the staff and professors have open-door policies so you don’t need to be hesitant to go in and ask for help.
