Research Interests

The main interest of my laboratory centers around the study of the effect of anthropogenic contaminant on aquatic organisms.  We focus on molecular approaches aimed at identifying the precise cellular and molecular pathways that are affected by different contaminants. Specific research projects address:

  • Effects of nanoparticulate metals on marine and freshwater fish
  • Application of molecular tools for assessment of ecosystem health
  • Isolation and characterization of miRNA expression patterns in non-model species
