Mathematics has fascinated me since childhood. My mathematical journey started with competitions like mathematics olympiad and talent search exams. I joined the Indian Statistical Institute, Bangalore to pursue Bachelor in Mathematics degree. I was then awarded the prestigious commonwealth scholarship to pursue MSc. in Statistics degree at the London School of Economics and Political Sciences. I was then offered to obtain a doctorate degree in statistics at an umbrella program which was jointly run between the University of Oxford and University of Warwick.
I have more than 7 years of teaching experience in mathematical subjects. I covered a number of modules including Elementary Statistics, Mathematical Statistics, Time Series, Mathematical Finance, Statistical Inference, Hypothesis Testing, Econometrics, Optimisation, Coding in R, Python and MATLAB, Linear Algebra, Biostatistics. I am able to teach statistics and mathematics at all level of an education programme.
