@andylu I don't know if this sort of thing would interest you, but I was talking to my husband about security for prosthetic limbs and implants earlier following on from this article. I noticed your minors were Natural Sciences which is exceptionally cool 🙂 I don't know how many people are entering the field, but I am betting not nearly enough if they don't even have security enough to prevent a pacemaker being hacked after being told in advance about it.
