Erica Grant completed a Master of Public Health (MPH) in One Health at the University of Washington in Seattle in 2018. She joined the Desai lab in 2019 as part of the MICROH (Microbiomes in One Health) doctoral training programme, investigating the impacts of a fiber-deprived diet on the microbiome of gnotobiotic mice in early life. Erica also manages the Luxembourgish Fiber Cohort project (LUXFICO, https://clinicaltrials.gov/ct2/show/NCT04352231), a translational study to investigate effects of low-fiber consumption in humans using multi-omics approaches. In December 2022, Erica successfully defended her PhD thesis and is now continuing research at LIH as a postdoctoral fellow on the B-MARK project, a public-private collaboration building off of the LUXFICO project.
