Research interests

         Our research is now focused on study of genes involved in reproduction of an economically important marine shrimp. To manipulate gonad development process is able to improve rate of shrimp production by increasing quantities and quality of shrimp progeny in shorter period resulting in an increase of outcome for Thai farmers. Recently, our laboratory characterizes a potential peptide hormone, glass bottom boat (Gbb), an ortholog of vertebrate bone morphogenetic protein isoform 5/6/7/8), that play a role in vitellogenin (precursor of yolk protein) stimulation. Further study about molecular mechanisms of Gbb as well as application of the potential peptides as a shrimp feed diet is now ongoing. In addition, we are also interested in wastewater treatment after shrimp culture by using microorganisms such as bacteria and microalgae.
         We propose both basic knowledge-based research in molecular biology and applied research from our investigation. We use several molecular and biochemistry approaches to study such as cloning, gene expression quantification and recombinant peptide production. We also use an advantage of cultured cell line to study gene function.

Join us! We are currently looking and recruiting for M.Sc. or Ph.D. students!! You can contact us by email ( This email address is being protected from spambots. You need JavaScript enabled to view it.) or by yourself at the Department (office room Bsc1001/3).
