Welcome to thE Majumder Lab

The Majumder Lab is dedicated to using systems biology to investigate novel microbial metabolisms with a focus on promoting One Health and sustainability within an inclusive, collaborative, creative community that embodies that Wisconsin Idea.

Our current research goal is to determine multi-scale mechanisms of microbe-plastic interactions in various environments (i.e., Lakes, landfills, chickens) and to use metabolic engineering to upcycle agricultural wastes to next-gen bioplastics.

UW–Madison Land Acknowledgement: 

The Wisconsin Union occupies ancestral Ho-Chunk land, a place their nation has called Teejop (day-JOPE) since time immemorial. In an 1832 treaty, the Ho-Chunk were forced to cede this territory. Decades of ethnic cleansing followed when both the federal and state government repeatedly, but unsuccessfully, sought to forcibly remove the Ho-Chunk from Wisconsin.

We acknowledge the circumstances that led to the forced removal of the Ho-Chunk people, and honor their legacy of resistance and resilience. This history of colonization informs our work and vision for a collaborative future. We recognize and respect the inherent sovereignty of the Ho-Chunk Nation and the other ten First Nations within the boundaries of the state of Wisconsin.
Diversity Statement:

We value the contributions of each person and respect the profound ways that identity, culture, background, experience, status, abilities, and opinion enrich the university community. We commit ourselves to the pursuit of excellence in teaching, research, outreach, and diversity as inextricably linked goals.

The Department of Bacteriology fulfills its public mission by creating a welcoming and inclusive community for people from every perspective – people who as students, faculty, and staff serve Wisconsin and the world.
