Sofia Rodrigues Teixeira is a Postdoctoral Researcher at Tyndall National Institute, working on the development of electrochemical impedance biosensors for numerous biomedical applications, namely cortisol, hCG, IL17-A, Candida, CA125, RAGE, methylation (5mc) and acetylation (AcH3) markers in relevant samples and pharmacological studies. Sofia completed her PhD at Swansea University in 2014 on graphene biosensors and then worked as a national research network funded Fellow on development of epigenetic biomarker screening tools for ovarian cancer diagnosis. Her research interests include nano device fabrication, electrochemical functionalization and biosensors optimization. Sofia have recognised skills in clinical sample processing and analysis, immune diagnostics, surface electrochemistry and characterisation, electronic materials and microfabrication techniques. Sofia combines advanced material science with molecular and cellular biology techniques.
