Tongjun Gu

Bioinformatics Assistant Scientist

(352) 273-8058
191 CGRC


I received my B.S. on Biomedicine Engineering from Huazhong University of Science and Technology and Ph.D. on Bioinformatics from Institute of Biophysics Chinese Academy of Sciences in China. I did my Postdoc training in The Jackson Laboratory, where I developed pipelines and GWAS methods for studying the function and regulation of RNA editing in mouse populations. In addition, I made contribution to the field for the single point variants discovery from deep sequencing data and was invited to give talks at multiple professional conferences, such as Genome Informatics meeting at CSHL, 2nd generation sequencing meeting from GTC, and RNA Sciences in Cell and Developmental Biology II meeting from RIKEN CDB in Japan.

After my postdoc training, I worked at The University of Chicago on identifying key players in cancer development. Particularly, I played a leading role in the data analysis for two large projects (Chicago pancreatic cancer initiative and The Cancer Genome Atlas) and gained valuable experiences of handling samples of >2000 from getting the tumor tissue from patients to validating the data analysis results using PDX models and other experimental approaches.

In 2016, I moved to UF ICBR, where I perform consultation, experimental design and data analysis for researchers within UF and outside UF. I extended the scope of biological field beyond mouse and human, such as plants and bacteria. I also extended my data analysis skills beyond traditional machine learning and statistics, such as deep learning.
