Research Interests

In the Heras Lab, we use genomes, transcriptomes, microbiomes, and microplastics to answer questions related to adaptations, digestive physiology, conservation, and exposure to pollution.  We are interested in looking at the genetic variation of hemoglobin genes within marine fishes and how this is related to adaptations of occupying different oceanic depths.  Also, our research group includes understanding how gene copy number, patterns of gene expression, and gut microbiomes contribute to dietary specializations.  Lastly, we collaborate with the Moore Institute for Plastic Pollution Research to determine what type of pollutants are found in marine fishes.  Overall, our investigations provide insight on the molecular evolutionary and dietary processes within fishes to better understand physiological adaptations to their respective habitats.

The Heras Lab is committed to fostering an inclusive environment where everyone, regardless of background, identity, or experience, feels valued and respected. We believe that diversity enriches our research and innovation, driving us to explore new perspectives and ideas. We are dedicated to creating a space where all voices are heard and where everyone has equal opportunities to contribute, grow, and succeed!

The Heras Lab is part of the Biology Department at CSU San Bernardino.  I am seeking highly motivated students at the undergraduate or masters level to join my lab.  If you are interested in joining the Heras Lab and studying questions in evolutionary genetics (especially on fishes), please contact me via email - Joseph.Heras'AT'csusb.edu
