Collecting pipefish from the Gulf of Mexico.

The Jones Lab uses modern genetic and computational techniques to understand various facets of the evolutionary process. The main interests of the lab include parentage analysis, sexual selection, quantitative genetics, and the natural history of seahorses, pipefishes and seadragons.

Members of the Jones Lab

Nothing would happen in the Jones Lab without the great people who work in it. We wouldn’t get by without the help of our undergraduate researchers, either. Find out more about the people working in the Jones Lab on our People page!

Jones Lab Research

In the Jones Lab, we use modern molecular and computational techniques to study the evolutionary process. On the empirical side, we’re using fishes of the Family Syngnathidae (pipefishes, seahorses, and sea dragons) to study mating system evolution, precopulatory sexual selection, and postcopulatory sexual selection. We are also interested in the evolution of male pregnancy, the molecular evolution of “male pregnancy genes”, and the evolution of the unusual seahorse body plan. Other studies in the lab are taking advantage of the favorable attributes of Drosophila melanogaster to study female mating preference evolution. On the theoretical side, we’re using simulation-based models to investigate sexual selection and quantitative genetics theory. More details on these and other projects can be found on our Research page.

G-Matrix Online

The Jones Lab is interested in modern quantitative genetics and the G-matrix. We’ve put together a site dedicated to the role of the G-matrix in the evolutionary process, and you can see it here: G-matrix Online.

Information for Prospective Students

The Jones Lab is a veritable laboratory full of people. A good way to maintain a laboratory full of people is to have new people join the lab to replace other people who graduate and leave. The lab is mainly powered by undergraduates and Ph.D. students, and inquiries are always welcome. If you think you might be interested in joining the lab, take a look at our Join the Lab page.

Pictures and News from Jones Lab Events

When we aren’t working, we’re having fun. Not that our work isn’t fun, but sometimes we do other fun things, too. You can find pictures from some of these lab events on our Events page.

In the News

Sometimes our research makes it into the popular press. To see a list of some recent press releases and news stories focused on work in the Jones Lab, click this link and find yourself magically transported to our In the News page.
