I would start with genetics and genomics, then add some protein knowledge and focus on the techniques that rely mostly on informatics/bioinformatics, like Next-Generation Sequencing, chromatography and similar. Add some evolution and phylogenetic, which with a mathematical background should be straightforward to grasp.
