I'd say you're on the right track with linear algebra and then calculus. How much math you need really depends on what kind of role you're looking for, but understanding ordinary differential equations should be the minimum level of calculus you aim for. For many spots you'll need a passing familiarity with partial differential equations; for a few, you'll need to be an expert.Statistics and probability should be the next step. Really, you don't have to go too deep here - don't delve into the world of t-tests and F-tests, but figure out what a chi-squared distribution is all about. Understand Bayes Theorem.Then you might want to muck about with stochastic calculus. The best way to learn this, IMHO, is to read some very introductory stuff and then try to work problems out on your own with a pen and paper. Stochastic calculus texts tend to be extremely formulation- and notation-heavy and so put newcomers off. Best to have a decent intuition before you dive in and trying to figure out wtf the books are talking about, so you can translate back to something like normal math-speak.
