In this lecture, Nina Tandon discusses her research as a tissue engineer. Nina explains that the work being done consists of creating models of functioning organs that can be used effectively in pharmaceutical trials. The use of these engineered tissues and organs leads to drug development that is more personalized, cheaper, quicker, and reduces the need for animal and clinical testing. While the development of these tissue models is imperfect, the progress toward a more efficient and successful system of drug development seems to be in reach.
