Liangliang Gao

Liangliang Gao is a post-doctoral Research Associate in bioinformatics, working in Dr. Jesse Poland’s group at Kansas State University. Dr. Gao joined the Poland Lab in Aug 2016 and his main research goal is to lead computational approaches to utilize next generation sequencing data for genomics-assisted breeding in wheat. Dr. Gao is developing improved approaches for analysis of genotyping by sequencing (GBS) data and whole genome sequence data for genome anchoring and translate genomic information to prediction models for genomic selection.

As of June 2017, Dr. Gao mainly worked on three projects at the Poland lab:

  • 1) Validating the Chinese Spring wheat reference genome assembly using de novo GBS maps and physical BAC sequences of wheat chromosomes 1D, 4D, 6D and 3A
  • 2) Identification of an alien wheat fragment (Aegilops ventricosa 2NS) in Kansas wheat breeding lines and preliminary 2NS-yield relationships analysis
  • 3) Generating a draft and ordered genome sequence for winter wheat cultivar Jagger using chromosome conformation capture and massively parallel sequencing (Hi-C)

Dr. Gao’s research projects at the Poland lab might also include developing novel genotyping assays for wheat, pan genome analysis in wheat, and potentially Hi-C genome anchoring for intermediate wheatgrass.


Past achievements

Dr. Gao published nine journal articles, one book chapter and over 12 abstracts for scientific conferences (google scholar profile: Dr. Gao’s previous research focused on organ specific defense against late blight in potato, mapping wheat genes effective to rust diseases, genome wide association study of wheat disease resistance traits, and genomic selections in wheat scab resistance. Dr. Gao also served as a reviewer for 19 pre-publication journal articles (Journal review profile: Dr. Gao actively develops novel and efficient computer programs or pipelines to automate crop science data conversion (Github site:
