Indian-American student Sai Sri Valli Mogilineedi has been named one of 30 national finalists in the 2026 Thermo Fisher Scientific Junior Innovators Challenge, a leading U.S. STEM research competition for middle school students. She was selected from 1,997 entrants representing communities across the country.
Now a student at Cumberland Valley Ninth Grade Academy in Pennsylvania, Sai Sri Valli conducted the research as an eighth-grader at Mountain View Middle School in Mechanicsburg. Her project focuses on developing a controlled-release system for medications used to address Gastroesophageal Reflux Disease, or GERD.
The idea was inspired by her grandfather’s experience with persistent heartburn and the limited duration of relief provided by conventional over-the-counter antacids. This led her to investigate whether an antacid could be designed to release its active ingredient more gradually and provide longer-lasting relief.
For her project, titled “A Novel Controlled Release System for GERD Drugs Using Immobilization Techniques,” Sai Sri Valli experimented with calcium carbonate, a common active ingredient in antacids, and incorporated it into calcium alginate beads. She used sodium alginate, a substance derived from algae, to create the gel-like structure and then examined how the beads behaved under different pH conditions.
Her experiments found that the calcium alginate beads released calcium carbonate more slowly under acidic conditions similar to those found in the stomach, while the release was faster in a basic solution. The findings indicated that the approach could potentially support a more controlled delivery of the antacid.
The research received recognition at the Capital Area Science and Engineering Fair and helped advance Sai Sri Valli to the national Junior Innovators Challenge. The competition selects young researchers for their scientific creativity, research skills and ability to address real-world challenges.
As a national finalist, Sai Sri Valli is set to participate in Finals Week in Washington, D.C., where the finalists will take part in hands-on STEM challenges and present their research to judges. The competition features more than $100,000 in awards, including the $25,000 Thermo Fisher Scientific ASCEND Award.
Beyond science, Sai Sri Valli participates in Science Olympiad and has interests in ecology and forensics. She also plays the violin and oboe, performs Kuchipudi, and volunteers with Caitlin’s Smiles, helping prepare craft kits for children in hospitals. She has expressed an interest in pursuing a career in surgery, reflecting her broader interest in human anatomy, physiology and disease.
Her journey from an eighth-grade science project inspired by a family experience to a national STEM competition highlights the growing role of young innovators in developing creative approaches to real-world challenges.
