My interests focus on two broad topics of fish biology: breeding behavior and adaption to different habitats. I aim to understand how species adapt (behaviorally, morphologically, physiologically, etc.) to different environments. I like to explore these topics in under-utilized species, thus increasing our knowledge of non-model fish species in the process.
