As a habit it is bad, but this is actually standard for short bios. It allows it to be dropped in place directly for conferences, PR shots, news articles, etc without any rewrite.
How do you figure? Every time I've been asked for a bio for a conference or similar, they've asked for it in third person. Reading bios in conference proceeding in first person would just come across as weird to me.
