Dr Gi Yoon Shin
Biochemistry, Genetics and Microbiology
I joined FABI in my final year of Bsc Microbiology as a mentorship student through CTHB Mentorship Program. I was mentored by Dr Carrie Brady who taught me great enthusiasm and fun in doing research as a post-graduate student.
For my both Hons and MSc, I worked on the projects looking at 'Identification of a causal agent of Pomegranate leaf spots and canker disease' and 'Investigation of the genetic diversity of an emerging phytopathogen Pantoea ananatis' under the supervision of Prof. Teresa Coutinho and Prof. Fanus Venter in FABI.
I continued to work with the phytopathogen P. ananatis in my PhD project under the supervision of Prof. Teresa Coutinho, Prof. Lucy Moleleki and Dr Divine Shyntum in which I characterized the functional role of an RNA chaperone Hfq and identified Hfq-(sRNAs) dependent small regulatory RNAs s in P. ananatis. This work showed that Hfq collectively regulates motility, AHL (Acylated-homoserine lactone, autoinducer) production, biofilm formation and pathogenicity of P. ananatis and identified novel P. ananatis-specific sRNAs.
Currently, I am working as a postdoctoral fellow in Centre for Microbial Ecology and Genomics (CMEG) on a project that is aimed to identify and express a novel enzyme found in an extreme environment. This project is under the supervision of Prof. Don Cowan and Dr Pedro Lebre.
