Summary

**Accepting self-funded PhD students** 

David Rusling completed his doctoral studies in Chemistry at the University of Southampton in 2005 under the mentorship of Professors Tom Brown and Keith Fox, focusing on the sequence-specific recognition of DNA by parallel triplex formation. His early research centred on the development of modified triplex-forming oligonucleotides (TFOs) as programmable DNA-recognition agents, with potential applications in gene targeting and molecular therapeutics. He subsequently undertook postdoctoral research at the University of Southampton and the University of Bristol, where he investigated DNA recognition by restriction endonucleases, before moving to New York University as a Visiting Scholar with Professor Nadrian Seeman, a pioneer of DNA nanotechnology.

David later returned to the University of Southampton, where he developed an independent research programme at the interface of nucleic acid chemistry, chemical biology and bioengineering. In 2021, he joined the University of Portsmouth, where he has established a research group focused on engineering nucleic acid-based platforms for biotechnology and healthcare. His laboratory uses multidisciplinary approaches spanning chemical design, biophysical characterisation, molecular biology and cell-based assays to investigate DNA recognition, triplex-forming oligonucleotides, DNA origami and nucleic acid nanostructures. His work aims to understand and exploit sequence-specific DNA recognition for precision gene targeting, synthetic biology, therapeutic discovery and molecular engineering. David is also Executive Editor of Nucleic Acids Research and co-leads a BBSRC-funded network supporting innovation across the UK nucleic acids community.
