Description of Research Expertise

Research Interests:
The lab develops machine learning algorithms that integrate high-throughput data (RNASeq, CLIPSeq , PIPSeq, etc.) to infer RNA biogenesis and function, followed by experimental verifications of inferred mechanisms.

Keywords:
Machine learning, probabilistic graphical models, computational biology, RNA splicing, post-transcriptional regulation, genomics, high-throughput sequencing analysis.

Cancer Discovery 5(12): 1282-95, December 2015 Notes: Barash performed RNASeq analysis, using his splicing code models he identified SRFS3 as differentially expressed & promoting CART19 treatment escape & relapse. He performed splicing analysis of RNASeq experiments to screen effects of possible splice factors.
