Dr Nina Vyas

School of Dentistry
Research Fellow

Nina Vyas is a Research Fellow in the School of Dentistry. She obtained her PhD in Biomedical Imaging from the Physical Sciences of Imaging in the Biomedical Sciences (PSIBS) Doctoral Training Centre, University of Birmingham, in 2016. Her PhD was based in the School of Dentistry and focussed on imaging and image analysis of cavitation bubbles around dental ultrasonic scalers. She undertakes interdisciplinary research at the life sciences interface in the fields of Biomedical Imaging, Biomaterials and Ultrasonics.


  • Ph.D Biomedical Imaging, University of Birmingham, 2016       
  • M.Sc. Physical Sciences of Imaging in the Biomedical Sciences, University of Birmingham, 2013  
  • BSc. (Hons) Physics, University of Warwick, 2012 


Nina graduated in Physics from the University of Warwick in 2012. She then joined an EPSRC-funded Centre for Doctoral Training at the University of Birmingham in the Physical Sciences of Imaging in the Biomedical Sciences (PSIBS). The focus of the centre is on interdisciplinary science and integration between the life sciences, physical sciences and computational sciences. Here she completed an MSc in 2012 and a PhD in 2016. Her PhD was between the Schools of Dentistry and Computer Science and was focussed on imaging cavitation bubbles around ultrasonic scalers for improving periodontal therapy.

She joined the School of Dentistry in January 2017 as a Research Fellow. She worked on a 6 month industry-funded project using confocal microscopy, image analysis and microbiology and is currently researching cavitation around ultrasonic scalers as part of an EPSRC grant between the Schools of Dentistry and Mathematics (EP/P015743/1).


Interdisciplinary research in healthcare innovation

  • Biomedical Imaging: e.g. Electron microscopy, fluorescence microscopy & microCT imaging of biofilm disruption
  • Biomaterials: e.g. Nanoparticles for hypersensitivity, biofilm mimicking hydrogels
  • Ultrasonics: High speed imaging & image analysis of cavitation
