Leslie Cunningham


Leslie Cunningham completed her bachelor’s degree in Health Sciences and Technology and master’s degree in Medical Technology at ETH Zürich. During her master’s thesis project in the Lewis Lab at Harvard University, she focused on modelling the proximal tubule of the nephron with organoid-derived cells. In her research internship in the macromolecular engineering lab at ETH, she worked on the encapsulation of single cells in micro-patterned hydrogel niches to analyse geometry-induced changes in contractile forces using molecular tension sensors. She then joined the biotech startup Rejuveron and worked on developing a blood brain barrier model for in vitro drug screening. In December 2021 she started her PhD under the supervision of Prof. Tibbitt in collaboration with Liver4Life. Her research focuses on the regeneration of ex-vivo perfused livers. She supports Liver4Life during perfusions and investigates ex-vivo liver therapeutics.
