Don't have any materials to point to, sadly. Most of the knowledge in this field is locked up in papers and tools; I was lucky to learn most of what I know from a graduate class taught by a professor working on static analysis in V8 and working with/on software security tooling. To begin with, I'd suggest first brushing up on compiler optimizations (which is largely separate from parsing) and that should lead you to dataflow analysis techniques.
