Designing Probes To Image Proteins Inside Living Cells
Samuel Thompson discusses his research on designing new tools to track the movement of proteins within cells. He explains how understanding the relationship between pKa and pH was critical for the design of a new sensor, which he hopes can be used to image proteins in diseased cells.
Samuel Thompson’s Personal Story
Samuel Thompson brings a sense of play to his science research that he traces back to his love of the performing arts and his early exposure to science as a child. He also relates that his identity as a gay-man from a conservative Southern town helped shape him into a scientist.
