Dr Neenu Singh

Dr Neenu Singh received her PhD in Biomedical Science at the University of Wales Institute, Cardiff (UK) in 2007 and MSc in Medical Biochemistry (with distinction) in 2003. She then worked as a post-doctoral research officer in Nanotoxicology at Swansea University Medical School Medicine, before joining Ð԰ɵç̨ as a Lecturer in Biomedical/Medical Science.

Her multi-disciplinary position specializes in assessment of nanoparticle interactions with biological cells, toxicology of nanomaterials including skills in DNA damage assessment and its associated biological mechanisms of action, in addition to nanomaterial physico-chemical characterization. She has visited and worked in various universities and organizations, including Rice and Texas A&M Universities (under the Texas-UK Collaborative), National Institute of Standards and Technology (NIST), USA and University of Rome TorVergata.
