Dr Tunn has an academic background in the biomedical sciences and is experienced in a wide range of molecular biology techniques, including protein expression and analysis, stem cell culture, and quantitative reverse transcription PCR. After gaining a BA in Physiological Sciences, she joined the Department of Pharmacology at the University of Oxford to study the molecular mechanisms underlying the development of fat cells and tissues. Specifically, she investigated intracellular calcium signaling and the expression of a family of cation channels (two-pore channels) in mammalian cells; the role of these channels in the differentiation of mesenchymal stem cells into fat cells (adipogenesis); and body composition in transgenic mice using time-domain nuclear magnetic resonance. She co-authored several papers on these topics, which were published in international journals including the Journal of Biological Chemistry, Endocrinology, and Molecular and Cellular Biology. During her PhD, Dr Tunn worked as a graduate teaching assistant and tutor for the preclinical medical degree program at the University of Oxford. After graduating, she obtained a Postgraduate Certificate of Education from Edge Hill University, specializing in mathematics. She joined the Edanz Group as a Senior Editor in 2015 and is based in the Fukuoka office.
