Geng Chen is a researcher at the Yangtze River Fisheries Research Institute, Chinese Academy of Fishery Sciences. His research focuses on the genetic basis of economically important traits in freshwater fish, particularly bighead carp (Hypophthalmichthys nobilis) and European perch (Perca fluviatilis). He combines whole-genome resequencing, population genomics, quantitative genetics, genome-wide association studies, QTL mapping, and transcriptomics to investigate growth, body shape, sex determination, and environmental adaptation. His work aims to identify genetic variants and candidate genes that can support genetic improvement and molecular breeding in freshwater aquaculture.
