Cause areas directly related to computer science besides AI risks?

I'm a high school student, my interest was in biology a little more, but I consider going to computer science in college.  Biology has a lot of directly related cause areas, like:global health, mental health, animal welfare, biotech(transhumanism or else), biorisks, neuroscience and sentience .. I'm not so familiar with computer science now, I can only come up with a directly related area: AI risk. I know CS skill is useful in any areas, like:bioinformatics, engineering... but in these areas, they seem more like an applied skill, not requiring a master or phD professionalism.

 But I wonder are there any other EA areas that are directly related to CS very much?
