Hi, I am a math and physics major planning on going into biophysics for grad school, and i want to do computational/mathematical modelling/theoretical work in the field. I have one more math course to take and im not sure which would be more useful. Here are their very brief course descriptions. Complex Variables:Analytic functions, integration, power series, residues, and conformal mapping. Elementary Stochastic Processes: Markov chains, Poisson process, and Brownian motion. Thank You!
