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.
Teaching responsibilities
My teaching is informed by research in areas including number theory, optimization, computational, discrete and industrial mathematics, and also mathematical education, with a focus on maths anxiety. I have been responsible for teaching some UG and PG modules:
3. DANCOP (with Outreach, School Liaison): £9420 (March 2018)
4. OCIS (On-Line Campus Internship Scheme): 120 posts for three students (March 2018)
Research interests
My research interests include number theory, optimization, computational, discrete and industrial mathematics, but also mathematical education, with a focus on maths anxiety.
In 2018, I had articles accepted in Neural Networks, Journal of Global Optimization, Carpathian J Math, Mathematics and Computers in Simulation and Asian Journal of Control. I have authored work with 40 collaborators from UK, India, Romania, Spain, China and Kuwait.
Some of my UG students have produced original research, disseminated through International Symposiums, Mathematical Magazines, or journal papers.
Four of my students have been awarded URSS bursaries to undertake research stages in Romania (Eve H. - Recurrent sequences 2016, Manzal and Chandni M. - Ceramics modelling2018) and Kenya (Navraj G - Sustainable agriculture 2018)
