Dr Ovidiu Bagdasar

About

I am Programme Leader for MSc Computational Mathematics, MSc Big Data Analytics and Departmental Coordinator for Mathematics and Computing for Erasmus+. I have been Placement Tutor for Mathematics students since 2012 and I am the International Recruitment Tutor for Mathematics programs and MSc Big Data. I am also Outreach Coordinator for Mathematics, selecting and training students for outreach activities.

Motto: "All what is correct thinking is either mathematics or feasible to be transposed in a mathematical model." (G. Moisil 1906 - 1973)

I hold BSc (2006), MSc (2007) Mathematics from UBB Cluj (Romania), PhD in Applied Mathematics in 2011 (EST Marie Curie Fellow, Nottingham) and PhD in Pure Mathematics in 2015 (UBB Cluj). I joined the University of Derby (UoD) in 2012 as a Lecturer in Mathematics when I became a member of IMA and Fellow of the HEA. In 2015, I became Senior Lecturer in Mathematics and Erasmus Departmental Coordinator for Mathematics and Computing. Since 2016 I involved students in URSS, Erasmus and research.

I am a member of the International Society for Difference Equations (2017-), American Mathematical Society (2014-), Romanian Mathematical Society (2013-) and the Marie Curie Alumni Network (2011-). I am an active member of the newly established Research Centre in Data Science at the University of Derby.
