30About Me
Dr Clement Twumasi is a Senior Medical Statistician at Oxford University Nuffield Department of Medicine. He previously worked at Clinical Trials Statistician at Imperial College London and held a postdoctorate in Biostatistics at the University of Oxford Statistics Department. He earned a PhD in Mathematics from Cardiff University in 2021 as a Vice Chancellor’s PhD Scholar, focusing on mathematical and stochastic models for biological systems. He completed his MPhil in Statistics from the University of Ghana & obtained a 4.0/4.0 GPA. His MPhil/master thesis was awarded the best research in mathematics in 2018 among all universities in Ghana. Dr Twumasi has outstanding academic track record within & outside the UK. He is also an academic reviewer for top Q1 high-impact Scopus journals. This includes the International Journal of Forecasting, PLOS One Journal, and PLOS Computational Biology Journal, where he reviews papers on time-series predictions using state-of-the-art time series models and machine learning techniques (with specific applications to blood supply chain) as well as works on mathematical biology/infectious disease modelling. He has a robust background in mathematics and statistics, with a wide range of mathematical modelling and computational expertise across diverse application areas.
My teaching style
My teaching style is student-centred, supportive, and highly practical. I focus on simplifying complex concepts using real-world examples, step-by-step guidance, and interactive problem-solving. I tailor each session to the student’s goals, whether it’s excelling in exams, mastering data analysis tools like R or Python, or building confidence in mathematics and statistics. With experience teaching everyone from GCSE/undergraduate and postgraduate students to PhD researchers, I adapt to different learning styles and provide clear explanations, structured notes, and plenty of practice. I encourage questions, foster independent thinking, and aim to make every student feel both challenged and supported.
My past experience
Yes, I have extensive teaching and tutoring experience across all levels. I am a Teaching Fellow (AdvanceHE, UK) and previously worked as a postgraduate teaching and research assistant during my MSc and PhD. I have taught undergraduate and postgraduate students in mathematics and statistics, and I provide one-to-one tutoring for GCSE, A-Level, and admissions tests (GRE, GMAT, ACT, SAT). I also support master’s and PhD candidates with research methods, data analysis, and statistical modelling. Beyond formal teaching, I run the Clement Twumasi Educative Channel on YouTube with 26,000+ subscribers, where I teach advanced statistical methods, R programming, and data science. Many of my students have gone on to achieve top grades, offers from leading universities, and perfect scores in admissions tests.
