added Experience and Publications section

first added bibtex entries, then compiled with a line calling \citep for each of the co-I refs, then copied bibitems from .bbl file into the main tex document so these don't have to appear in the separate bibliography.

Also made some minor wording changes to science justification and targeting sections
