Dong's research interests focus on understanding the molecular mechanisms of host-pathogen interactions using high-resolution approaches coupled to bioinformatics. He is interested in 'big data' analysis, where datasets generated from multiple omics platforms are integrated for system modelling.

Trained as an experimental biologist with hands-on mass spectrometer and bioinformatics skills, his work also contributes to the understanding of proteoforms, where splice variants and post translational modifications are experimentally and bioinformatically characterised followed by functional validations. The data generated also contribute to the next round of genome annotation as solid evidence of expression to improve gene model predictions.

• Identification of novel druggable targets in canine insulinoma through single-cell transcriptomic analysis

  

  Insulinomas in dogs are difficult to cure by surgery. We investigate which genes are crucial for survival of insulinoma cells, allowing us to design new treatments targeted at these genes. Insulinomas are the most common pancreatic neuroendocrine tumours in dogs and humans. Current treatment options are limited to surgery and palliative medical therapy. Survival is poor with a median of 4 [range 0-18] months and 14 [range 0-51] months for medically and surgically treated dogs, respectively. Hence, new, more precise treatments are needed to improve the clinical outcome for dogs and humans with malignant insulinomas.

• Machine learning algorithms for predicting drug resistance against tuberculosis in people

  

  Tuberculosis disease (TB), caused by Mycobacterium tuberculosis, is an important global public health issue, and its drug resistance, caused by genetic mutations in the M. tuberculosis genome, poses serious challenges for effective control. Current molecular diagnostic tests are imperfect as they do not target all resistance mechanisms and drugs, nor do they inform on transmission clusters, and are therefore unable to guide completely effective individualised therapy.

  The SweetAnimal project studies the presence of sugar-binding receptors in the genomes of a variety of farmed animals, how these differ between species, what ligands expressed on pathogens they bind, and how this information can be used to develop carbohydrate-based vaccines.
