In collaboration with Drs. Harry Daniels and Ben Reading, we are using a genomic approach to understanding the population genomic structure of the southern flounder throughout its range. Our focus is on two regions, one in North Carolina and the other in Texas, with fine-scale sampling within each region. The library for samples taken in 2014 was recently completed and we are in the process of analyzing those data. We are also collaborating with Drs. Russell Borski and John Godwin to further investigate the genetic basis of sex determination in the southern flounder.
