YOOOO.
Haven't done up all the bios yet, but.
For medical science--particularly pathology--there's Pharma first and foremost. He is decidedly mad.
Kejutan (my own Shockbabe; used a foreign version of the name) is in charge of overseeing all non-medical science in the clan, and dabbles in quite a bit of everything. I wouldn't say mad or evil, but 'morally ambiguous' is a delicate way to put their approach.
Quintus is deeply engaged by the sciences of all living things, both in their natural state and the idea of biological improvements. Kejutan has gently led him into a lot of awful projects but he's a gentle soul. Botany makes his heart sing.
Back to medical science, First Aid is big on coming up with crazy new treatments for all those crazy new plagues that start mysteriously cropping up around the clan. Her approach is not very scientific though so not sure if count.
Drift is a slob, but slick with astronomy and astrophysics both. Also a compulsive bull artist.
Cordite is married to the science of Making Stuff Blow Up. Traachon is currently planning to militarize this as soon as she can figure out how.
Stachys, known around the clan as 'Apothecary Woundwort', is a chemist. While quite a bit of her work is put to medicinal purposes, she dabbles elsewhere.
Rhodorian is basically a robot zombie at this point. Mechanical and biomechanical supplements, replacements, and prosthetics are his speciality, though Kejutan has sort of usurped a few of those projects and taken the biomech into directions he would not have. He unconditionally resents not being in charge of the clan's science goings-on and there's a 100% chance he's plotting Kejutan's demise.
Glitch is an engineer and Rhodorian is 200% his hero, he may try to kill Kejutan and end up with a lobotomy for his trouble.
Vector studies temporal and quantum theory, but no one is sure if there's any more going on there than pure research and speculation.
BONUS ROUND:
Chro experiments on the living and the dead of Delphi; he trades for the rights to do so with the results of his work. What exactly does he do? That's classified.
Probably missed a few but that's all right because I ought to be sleeping. HAH.
