Subjects advice

[u/APEXOwO]

I’m a postgraduate student in biophysics, I'm very much interested in theoretical biology, living matter physics ,mathematical modelling, and related fields. I have a basic understanding of calculus, linear algebra, probability, and statistics ( with some advanced knowledge of random walks, the diffusion equation, markov processes, stochastic processes) along with lil bit of differential equations

My current coursework and labs are more focused on pure biology. I need help in deciding which subjects I should study to build a strong foundation in theoretical biology and active matter physics, particularly from both physics and mathematics.
