The Tuite Lab works at the interface of life and physical sciences, applying chemical and physical tools to biological, materials, and environmental problems.
We have particular interests in the chemistry, dynamics, and recognition of DNA in the context of nano-assembly, synthetic biology, molecular diagnostics, and photodynamic therapy. Another research line involves optical spectroscopy, photophysics, photochemistry, and photobiology.
Together with the Pike Group, we form the Bioinspired Molecular Engineering Group.
In April 2021, assisted by Innovate UK, we jointly spun out NunaBio Ltd to provide provide DNA solutions for microbial detection and biochemical research.
Background
My undergraduate and postgraduate studies were at Trinity College Dublin. In 1992, I completed my PhD in the School of Chemistry with Prof John Kelly on photosensitized damage of DNA. I then moved to Gothenburg on the Swedish west coast for postdoctoral work with Prof Bengt Norden at Chalmers University of Technology in the field of biomolecular recognition, and subsequently accepted an Assistant Professorship there. In 2000 I moved to a lectureship at Newcastle where I have continued to expand my research in Biophysical Chemistry.
