Dr Joshua Lehr

Lecturer in Inorganic Chemistry

Biography

After completing my undergraduate degree in chemistry at the University of Canterbury (New Zealand) I undertook a PhD at the same at the same institution investigating the formation of thin organic films at electrodes via radical grafting processes. I subsequently carried out considerable postdoctoral research at the University of Oxford (United Kingdom) focused on supramolecular systems for molecular recognition and the development of (bio-)sensors. Thereafter I took up a lecturing position at Nottingham Trent University before moving to the University of Salford in 2018 to take up the position of Lecturer in Inorganic Chemistry.

Teaching

I have experience teaching at most undergraduate levels, primarily in the area of inorganic chemistry. I have also taught at Masters level. This academic year (2018/2019) my primary teaching focus is to develop and deliver a new level 5 bio-inorganic chemistry module, for which I am module leader.

Research Interests

My research is interdisciplinary and at the intersection of chemistry, nanotechnology, biology, and engineering. Broadly speaking it has focused on construction and study of functional molecular architectures at interfaces. This leads to the development of switchable surfaces, sensors, supramolecular interfaces, and bioelectronic interfaces for medical diagnostics. Complimentary to this work, I have an interest in the fundamental study of the formation, characteristics, and electrochemical behaviour of thin organic films at electrodes. Additionally I also have an interest energy materials for batteries and capacitors.
