Sharon Walker holds the John Babbage Chair In Environmental Engineering. She is also associate dean of the Graduate Division. Watch a video of Walker talking about her research.

On Water Quality

Walker’s research focuses on optimizing effective water treatment and distribution, wastewater reclamation and understanding mechanisms controlling microbial and particle transport in water. She received significant media attention, including in Scientific American and IEEE Spectrum, for research on how graphene is transported in water.

On Food Safety

Walker’s research focuses on preventing food-related bacterial outbreaks caused by contaminated irrigation sources. Her lab analyzes every stage of the food production and distribution process, paying particular attention to the growth, harvesting, rinsing, packaging and retail practices associated with the produce that ends up on our tables. Her lab’s findings enable the USDA to better regulate land management policies, as well as specific harvesting and handling procedures that contribute to contamination.
