Iryna R.

Mathematician | PDEs | ODEs | Numerics

I am a proficient mathematician and gained my PhD degree in mathematics in 2008. My field of research is mainly partial differential equations analysis but also includes ordinary differential equations and numerical modelling. I have published a number of high-level research papers, worked as a referee for scientific journals and wrote reviews for Mathematical reviews. I can help you with understanding research papers in this field, writing mathematics-related texts and reviews, and research tasks. I have teaching experience with university courses on partial differential equations, numerical analysis and calculus. Also I can help students with courses on algebra, geometry and ordinary differential equations. I use Octave for numerical modeling and teaching. I worked as a web developer in the past (mainly back-end, PHP and SQL) and can write code for mathematics to include it in the main program. I am also familiar with Python and C on a basic level.
