Biography and Research -

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 combined Biomedical Imaging, Biomaterials and Ultrasonics and was focussed on imaging cavitation bubbles around ultrasonic scalers for improving periodontal therapy.

She joined the School of Dentistry at the University of Birmingham in 2017 as a Research Fellow. She worked on a 6 month industry-funded project using confocal microscopy, image analysis and microbiology and then on an EPSRC funded project, where she was a named researcher on a grant continuing from her PhD. She worked on a collaboration between the Schools of Dentistry and Mathematics (EP/P015743/1) and developed several high speed imaging and image analysis protocols to understand how bacterial biofilm is removed by cavitation bubbles.

Her interest in developing novel imaging protocols for research at the life sciences interface led her to her current position at B24, where she is a Postdoctoral Research Associate at B24, working in correlative microscopy. She works on developing user friendly correlative workflows in collaboration with other leading researchers for sample preparation and data analysis at Diamond and internationally.
