Mentis Profile

B.S. Sungkyunkwan University, 2000
M.S. Sungkyunkwan University, 2002 
Ph.D. Ohio State University, 2010 
Post Doctorate: 
University of Pennsylvania, 2010-2020 (Gideon Dreyfuss)

Research Interests:

RNA-Protein complexes,
gene regulation,
macromolecular complex assembly and function

Current Research:

The focus of my research is to understand how RNA-protein complexes play a role in coding and non-coding gene expression using a various research tools including biochemistry, molecular/cell, and structural biology. Current research topics are 1) biogenesis of non-coding small nuclear RNAs; 2) interconnection between splicing and cleavage and polyadenylation machineries in coding gene processing; 3) perturbation of RNA processing and its link to diseases.



Byung Ran (Ranny) So joined the University of Texas at Arlington in Sep 2020. Dr. So received her Ph.D. degree in biological chemistry at the Ohio State University in 2010 under the guidance of Professor Karin Musier-Forsyth. She conducted her postdoctoral training with Professor Gideon Dreyfuss (National Academy of Sciences) in the Department of Biochemistry and Biophysics at the School of Medicine, at the University of Pennsylvania /Howard Hughes Medical Institute (HHMI). Her multidisciplinary research centered on RNA-Protein complexes spans from synthetic organic chemistry to biochemistry, molecular biology, and drug discovery to elucidate underlying non-coding RNA-protein complex mediated mechanisms in post-transcriptional gene regulation and translational quality control.
