Who we are

We are a group of scientists at the Cavendish Lab, University of Cambridge, UK. Our research is focused on understanding transport processes through membranes.

The physics of ions, macromolecules and particles in confined geometries at the single molecule/-particle level is of particular interest. We exert maximum control over all parameters in our experiments using several techniques: DNA (origami) self-assembly, optical trapping, particle tracking, fluorescence microscopy, electrophysiology, or micro-/nanofluidics, often in combination.

Our interdisciplinary team combines researchers with expertise in physics, engineering, physical chemistry, biochemistry/biology, and micro- and nanofabrication.

In case you are interested in working with us, please get in touch with Ulrich by email: ufk20 (at) cam.ac.uk.

We gratefully acknowledge funding of our work from various sources including:

8/6/2022 June '22 update.
Over the last months we have published Jinbo's work on using split G-quadruplexes to enhance nanopore signals, Jeff's work on 3D optical tracking for optical tweezers, Ran quantified proton transport into OLA vesicles, and Mohammed measured life time of glass nanopores for single molecule sensing.

We also welcome NanoDTC Midi project student Gerardo Patino Guillen.

20/2/2022 February '22 update.
We received a Proof-of-Concept grant from ERC. Contract negotiations ahead. We have published collaborative work with Knowles group on nanofluidic sizing, DNA guided assembly of dye molecules with Auras and Friend groups, and our News & Views on nanopore protein analysis in Science.

We also welcome Hein Mante and Matthew Zhang as Part III students.

9/1/2022 Yunxuan Li joins the KeyserLab. Welcome.

Yunxuan joins us from Tsinghua University to work on nanopore sensing and her PhD. We wish you a good start to the work.
