Bareun Kim, Ph.D.

Postdoctoral Researcher

I grew up in Busan the 2nd largest city, Republic of Korea. I studied at Pusan National University and earned B.S., M.S., and Ph.D. Doing research is the most enjoyable part of my life, weekdays only. On weekends, I usually enjoy playing tennis, cooking, and watching classical music concert with friends. I’m trying to achieve and maintain a good work-life balance. Hopefully, I keep it till I will retire, please!

Sonia Fuentes Lewey

Sonia Fuentes Lewey

Graduate Student Researcher

Sonia completed her undergraduate studies with a B.S. in biology from the University of North Texas. She then worked as a research technician here at UTSW for three years studying diabetes pathogenesis before she transitioned to a graduate student in the Osborne Lab. Currently, she is investigating the interactive role of the RNA-binding protein Lin28 and transcription factor Sox9 in lung development and cancer tumorigenesis. She hopes to use her training to develop a career specializing in creating novel therapeutics for a wide variety of human diseases. As a Washington State native, Sonia enjoys the sun here in Texas, but also misses skiing and snowboarding back home. She loves to spend her free time doing absolutely nothing together with her husband and baby boy.
