AQUATIC FUNCTIONAL GENOMICS

While our knowledge of the genetic structure of life is progressing at an unprecedented rate, decoding the function of individual genes and their role in complex molecular networks remains a major scientific challenge.  The Phelps laboratory is interested in understanding how genetic variation influences physiological function in animals, to gain insight into the underlying drivers of important phenotypic traits.  We take an integrated physiology approach, investigating gene function in aquatic organisms from the molecular, cellular and organismal levels.

The laboratory is particularly interested in identifying the genetic factors that control the growth and size of animals and tissues, with special emphasis on the growth and development skeletal muscle in teleost fish.  Our research also develops new targeted-DNA sequencing and CRISPR genome-editing technologies to characterize gene function in non-model aquatic species that have direct agricultural or environmental importance.  This includes a major focus on functional mapping of the genome in wild and cultured salmonids, to identify genes critical for growth, health and environmental adaptation.  The Phelps laboratory addresses both basic and applied biological questions to further knowledge of fundamental muscle growth pathways in aquatic organisms while identifying ways to enhance salmonid conservation and aquaculture production.

Specific Research Areas:

  • Characterization of the activin/myostatin signaling pathway in fish muscle growth
  • Functional annotation of the salmonid genome
  • Gene discovery and characterization in non-model aquatic species
