Yunxuan Li is a research associate at the Cavendish Laboratory, University of Cambridge, working with Professor Ulrich F Keyser. Her research sits at the interface of DNA and RNA nanotechnology and single-molecule biophysics, using solid-state nanopores to read nucleic acids. She is particularly interested in resolving single-nucleotide RNA mutations and modifications, in multiplexed single-molecule readout for pathogen identification and in what it takes to move programmable nanostructures from proof-of-concept experiments towards practical molecular diagnostics.
