The term “glycobiology” may be unfamiliar to many students, as it is an undertaught but extremely important field that is linked to nearly every facet of cellular biology. Glycobiology is the study of carbohydrates, also known as glycans. On this exciting episode of Let’s Talk Chemistry edited by David Alvia, hosts Erin Suh, Jasmine Winter, and Diya Garrepally dive into our interview with Dr. Lance Wells. Dr. Wells shares his research on XLID, an intellectual disability syndrome linked to mutations in OGT, an enzyme that adds a type of glycan, called O-GlcNAc, onto proteins. He also shares how glycans can be used to modify drugs through a process called glycosylation to make them more effective. We hope you enjoy!
Dr. Megna Tiwari and Advancing Glycoscience Education:
Her Path from Infectious Agents to Glycobiology to Science Education
Dr. Megna Tiwari A Journey Through Science and Education
Dr. Megna Tiwari’s scientific journey has been anything but linear—beginning as an undergraduate fascinated by biology, continuing through work as a blood bank laboratory technician, and advancing through a master’s, Ph.D., and postdoctoral training.
Her early research focused on infectious agents, but an unexpected encounter with glycobiology sparked a new scientific passion. Captivated by the intricate world of glycans, she began exploring how these small but powerful sugar molecules influence nearly every biological process—a realization she often sums up with the phrase, “From small sugars come big things.”
By the end of her Ph.D., Dr. Tiwari’s curiosity had expanded beyond the lab bench to include the question of how students thrive in science. This led her to combine her love for glycobiology with a growing dedication to science education research.
Now a postdoctoral researcher with Dr. Erin Dolan and the BioF:GREAT team, Dr. Tiwari is helping to democratize glycoscience—developing, testing, and sharing glycoscience teaching materials designed to work across diverse classrooms and learning environments. Her overarching goal is to build national capacity for glycoscience education, ensuring that students and educators alike have access to the tools and knowledge needed to bring this vital field into mainstream biological education.
JAAG Software: A Glycan Modeling tool Developed by BioF:GREAT Team Members
Chin Huang Develops JAAG Software
Chin Huang, a graduate student in Dr. Kelley Moremen’s BioF:GREAT laboratory, has developed a web-based tool that helps glycan modeling by Alphafold 3.
AlphaFold 3 can accurately model glycans with proper stereochemistry only when using the BAP+CCD syntax, but manually creating these inputs is tedious and error-prone. To streamline the process, JAAG—a lightweight, user-friendly web tool—automates the conversion of glycans drawn by users into BAP+CCD syntax. This makes it easier for scientists to model glycoproteins and glycan–protein interactions, helping even AlphaFold 3 beginners generate reliable, stereochemically valid structures effortlessly.
