David is a National Teaching Fellow of the Higher Education Academy and has been awarded the Sheffield Hallam Vice Chancellor's Award for Inspirational Teaching. His research interests bring together protein chemistry, cell culture and mass spectrometry to investigate the molecular basis of Parkinson's disease. This research is applied directly to his teaching giving context and authenticity, an approach that has been recognised through the nomination of the University Inspirational Teaching Award to the maximum of three times and faculty award seven times.
David is passionate about disseminating and enhancing teaching practises. He has worked directly with bioscientists and other academics across multiple institutions on teaching enhancements and delivers invited workshops and conference presentations on student engagement. He has developed the pedagogical theory of object-based learning through the use of 3D-printed biological molecules, producing digital tool kits to disseminate this practice. He has also integrated various forms of technology enhanced learning into the practice of the department from the use of Padlet for student support, collaborative learning tools to facilitate interaction and lecture flipping technologies.
Specialist areas of interest
Biochemistry / Biotechnology
Ion Mobility Spectrometry - Mass Spectrometry
David teaches core biochemistry and the molecular biosciences and is currently course leader for MSc Molecular and Cellular Biology.
David's research is focussed on understanding the structure and function of amyloid oligomers thought to be responsible for cell death in Parkinson's disease.
Parkinson's disease (PD)
PD occurs in 0.17% of the general population affecting ~1 to 2 per cent of those over 80 years old. Although rare heritable forms of PD have been documented, the sporadic form is far more common and this is possibly connected to environmental factors. The molecular mechanisms of neurodegeneration in PD are mostly unknown and the lack of preventative treatments for PD is undoubtedly a result of our limited understanding of the underlying aetiology. A critical step is the formation of metal rich Lewy bodies, in which alpha-synuclein in the form of amyloid-like aggregates has been identified as a major component. Soluble alpha-synuclein oligomers populated during amyloid assembly have been implicated as the causative agent in PD. David's group is developing novel 3D cell culture systems to investigate the molecular basis of the Lewy body formation brought about by exposure to metals and these oligomers.
Ion mobility mass spectrometry of non-covalent complexes
Detailed knowledge of the tertiary and quaternary structure of proteins and protein complexes is of immense importance in understanding their functionality. To investigate this, David carries out research using electrospray ionisation - ion mobility spectrometry - mass spectrometry (ESI-IMS-MS). This is an analytical technique used to characterise the conformational states of monomeric proteins and large non-covalent complexes such as amyloid oligomers. ESI-IMS-MS is used to assess the size (molecular weight) and shape distribution (CCS) of the oligomers and any covalent modification to the protein. By comparison with models, estimates of the degree of compactness and general shape adopted by the oligomers is possible. Through this work the structural and conformation of differing forms of alpha-synuclein oligomers as well as the effect of phosphorylation and metal binding is being addressed. The results gained raise the possibility of intervention via small molecule inhibition, as differences between toxic and non-toxic oligomeric forms are identified.

David is particularly interested in how proteins, the molecular machines within the brain, change their shape and come together, creating neuro-degenerative diseases such as Alzheimer's disease and Parkinson's disease. Current research interests are centred on linking the structure of complexes to their toxic of function.
