Robert A. Redden, MS

PhD Candidate

My research focuses on 3D organoid culture to investigate basic biology and directed differentiation of human induced pluripotent stem cells under partial- and microgravity in the random positioning machine. In addition, I am using mathematical and computational techniques to model cell aggregation into organoids and cell proliferation within growing organoids, including the influences of cell density, biological heterogeneity, metabolism, nutrient and oxygen gradients, et al on cell behavior.
