In an inspiring collaboration aimed at expanding the horizons of biopolymer research, South Dakota Mines is hosting Aparna Banerjee, Ph.D., a professor from the Universidad Autónoma de Chile. Her presence in Rapid City extends the ongoing scientific exchange between the United States and Chile under the prestigious Concurso Interno de Estadías de Investigación en el Extranjero para Académicos Jerarquizados Asociados y Titulares 2025 fellowship.
Dr. Banerjee’s research focuses on the exploration of extremophilic microorganisms and their unique biopolymers, sourced from some of the planet’s most hostile environments—volcanoes, oceanic trenches, and thermal springs. These biopolymers hold promise for advancements in food and agricultural technologies. On her South Dakota Mines visit, she joins forces with renowned faculty in an invigorating academic atmosphere that fosters international collaboration and innovation.

A central figure in this transcontinental endeavor is Rajesh Sani, Ph.D., a respected professor at South Dakota Mines and the leader of the Multiomics and Synthetic Biology Center (MASON) Lab. Dr. Sani’s collaboration with Dr. Banerjee dates back nearly ten years, a relationship that has been nurtured through projects funded by the Chilean Antarctic Institute. Their joint research delves into how extremophiles, resilient microbial life forms, can inspire groundbreaking biotechnologies.
The partnership between Dr. Banerjee and South Dakota Mines leverages state-of-the-art facilities across several departments, including the Engineering and Mining Experiment Station, the Department of Chemistry, Biology & Health Sciences, and the Karen M. Swindler Department of Chemical and Biological Engineering. Together, they are examining the surface properties of biopolymer samples using cutting-edge technology, aiming to develop materials that are cleaner, more sustainable, and versatile for future applications.

During her visit, Dr. Banerjee conducted an illuminating seminar titled “Extremophiles from Volcanoes, Trenches, and Thermal Springs: Microbial Polysaccharides for Food and Agricultural Innovation.” This presentation highlighted the transformative potential of extremophilic biopolymers, sparking interest among the students and faculty of South Dakota Mines, a community dedicated to scientific exploration and breakthroughs.
“It has been a pleasure to interact with students here and collaborating with researchers including Drs. Dipayan Samanta, Ram Singh, Priya Saxena, and Tanvi Govil,” said Dr. Banerjee during her lecture. “Science is truly universal and expanding collaborative networks like this is one of the most enriching aspects of research. This experience has been both scientifically and personally inspiring. It is a privilege to continue building this strong Chile and United States collaboration, exploring the fascinating world of extremophiles and their potential biotechnological applications.”

Dr. Dipayan Samanta, a research scientist at South Dakota Mines, underscores the importance of biopolymers found in extreme environments. “By studying their structure and properties, we can inspire new materials that are cleaner, stronger, and better for our world,” he said. “It is remarkable how life in extreme places can guide technologies for our future.”
This collaborative effort is a stepping stone for future scientific endeavors, as both institutions are working towards formalizing a Memorandum of Understanding (MoU) for comprehensive research training programs, faculty and student exchanges, and projects that foster academic growth and innovation across borders.
Dr. Sani explains, “Dr. Banerjee’s visit reflects our mission to cultivate global research networks that enrich science and society. These collaborations propel our work forward in energy, sustainability, and biomanufacturing while also training students to thrive in a connected world.”
International collaboration is indeed shaping the future of biotechnology, as demonstrated by this partnership right here in Rapid City, South Dakota. As molecular revelations unfold, each discovery holds the promise of contributing to a healthier, more sustainable planet.
“Every image captured under the microscope and every conversation in the lab reinforces one truth—curiosity knows no borders. Banerjee’s fellowship marks just the beginning of a long-term scientific friendship that bridges continents,” Dr. Sani concluded.
The MASON Lab and Universidad Autónoma de Chile aspire to co-publish research findings, nurturing a network of student researchers and scientists across international borders as they push the frontiers of energy, sustainability, and biomanufacturing.
By partnering with South Dakota Mines, Dr. Banerjee and her colleagues are not only advancing scientific knowledge but also fostering an enriching educational environment, empowering students to thrive in our ever-connected global community.
