One of the best opportunities for students interested in Bioinformatics @ UCLA is the tremendous number of research opportunities available on the campus. Undergraduate research is a great way to obtain the kind of project oriented “real world” experience that is hard to obtain from classes.
A list of available research projects for UCLA students is available at http://www.bioinformatics.ucla.edu/undergraduate-masters-research/. UCLA Masters students are also encouraged to get involved in these research projects.
I would recommend taking either Computer Science 124/224 (also Human Genetics 124/224) “Computational Genetics” or Computer Science 121/221 (also Chemistry 160A/260A) “Introduction to Bioinformatics” first, and then afterwards join a research group.
