Jennifer Ryder

Jennifer is the twin sister to Nick Ryder and currently the head of the Irena Kellow Medical Center formerly headquartered in Poznan, Poland - now located in Capitol City as a civilian medical center.
Jenny grew up very close to her mother and as soon as she passed her exams, went to medical school. Choosing instead of Starfleet Medical, to attend more traditional, yet more cutting edge medical schools. Starting out at Johns Hopkins, she then transferred to UCLA medical to be closer to her brother Nick after he was enhanced and spent months being looked at. Her mother tried, again, to get her to join Starfleet, but after the hell they put her brother through, she was even more adamant to not join Starfleet Medical.
Eventually earning her doctorate at the University of Paris and gaining a residency with an interspecies medical program. Which lead to her gaining some repute as a miracle worker, due to her studying her mother's own work in the field. 
During the Fall of the Federation, Jennifer assisted as best she could with her team of doctors and nurses to help with medical needs of refugees from Earth. In a rare bout of anger and aggression, she ordered the Clinic her mother founded in Poland be destroyed from orbit, and publically denounced the Federation/Imperium and spent more than six months with a bounty on her head.
She found her way to Terra Alpha and joined her siblings, but due to the bounty on her head, tried to stay in the shadows and help as she could. The Siofrans, when they briefly re-appeared and tried to help in the aftermath of the Federation's fall and the Alliance's rise to power, she was reunited with one of her mentors and followed her. 
She has since returned to Terra Alpha and rebuilt the clinic her mother founded, which was named after her grandmother, in a part of the Capitol City that was more diverse in its population and had residents from nearly every corner of the Alpha and Beta Quadrants and needed medical care that only a handful of doctors could really provide.
Jennifer is one of the few Ryder children not to follow her big brother into politics, preferring to stay where she can do the most good. Although the death of her father has made her weigh her options...
