Jones Lab Alumni

Many people have worked in the Jones Lab over the years. Here they are:

Graduate Students:

Kenyon Mobley (PhD, 2007): Kenyon’s dissertation research focused on geographic and temporal variation in mating systems. He also studied a number of other important topics related to sexual selection, such as postcopulatory sexual selection and reproductive compensation. He’s currently at the University of Helsinki. Here is a link to his personal webpage.

Charlyn Partridge (PhD, 2009): Charlyn’s dissertation work focused on the effects of environmental contaminants on pipefish physiology and behavior. Among other topics, she studied how endocrine disruptors affect male pipefish morphology and mating behavior, mercury contamination in pipefish populations, postcopulatory sexual selection, and pipefish population structure. Charlyn is an Assistant Professor at Grand Valley State University’s Robert B. Annis Water Resources Institute.

Sunny Scobell (PhD, 2011): Sunny’s research concerned the relationship between endocrinology and aggression in pipefish. She is a Visiting Assistant Professor at St. Edward’s University in Austin, TX.

Kimberly Paczolt (PhD, 2012): Kim studied postcopulatory sexual selection in Gulf pipefish. Her demonstration that males appear to discriminate against the offspring of small females during the male pregnancy was a major breakthrough in our understanding of sexual selection in Gulf pipefish. Kim is currently a lecturer and at the University of Maryland.

Clay Small (PhD, 2012): Clay used his time as a doctoral student to delve into next-generation sequencing approaches and their application to the molecular evolution of reproductive proteins. He used these approaches to understand how male-pregnancy genes evolve as a consequence of sexual selection and sexual conflict. Clay is currently a Research Associate working with Bill Cresko at the University of Oregon.

Nick Ratterman (PhD, 2012): Nick used Drosophila melanogaster and simulation-based models to explore his interest in the evolution of sexually selected traits and mating preferences. Nick is the co-founder of Better Brains and works in the private sector.

Emily Rose (PhD, 2016): Emily’s research spanned basic questions in sexual selection and applied questions in ecotoxicology and conservation biology. Emily explored how environmental endocrine disruptors affect the mating system and gene expression in Gulf pipefish. She also quantified pre- and postcopulatory sexual selection, used DNA markers to characterize a seahorse population of conservation concern in the Bahamas, and performed a number of additional studies on patterns of gene expression and population genomics in syngnathid fishes. Emily is a Visiting Assistant Professor at the University of Tampa.

Sarah Flanagan (PhD, 2016): Sarah pioneered the use of next-generation sequencing for population genomics analysis in pipefish. Her work especially focused on developing selection components analysis for next-generation markers, quantifying multivariate evolution, and applying molecular methods to identify signatures of local adaptation. Sarah is now a postdoc at the National Institute for Mathematical and Biological Synthesis (NIMBioS). Learn more about Sarah from her personal webpage.

Andrew Anderson (PhD, 2019): Drew studied the effects of sex-role reversal and sexual selection on genome evolution, with a particular focus on nuclear hormone receptor binding. He is now a Visiting Assistant Professor of Biology at Reed College. Click here to view his faculty profile.

Postdoctoral Scientists:

Eric Hoffman (2003-2004): Eric worked in the Jones Lab at Georgia Tech, before we moved to Texas A&M University. He studied a variety of topics, all of which fell into the broad categories of molecular ecology and evolutionary genetics. He’s currently an Associate Professor at University of Central Florida.

April Harlin-Cognato (2005-2006): April studied the molecular evolution of male pregnancy genes during her time as a postdoc. She went on to a position as an Assistant Professor at Michigan State University, and now she works in the private sector.

Karoline Fritzsche (2018-2020): Karo is interested in sexual selection and the evolution of sex roles in animals. Her work has spanned multiple empirical systems, including sex-role-reversed honeylocust beetles, cichlid fishes, and nematodes. In the Jones Lab, she contributed to a large comparative genomics enterprise aimed at understanding sexual selection in pipefishes and African turquoise killifish. Her personal website is here.

Jonathan Henshaw: (2018-2020): Jono is an evolutionary theorist, and his work focuses mainly on sexual selection, the evolution of sex roles, and the measurement of selection. During his time in the Jones Lab, he worked on models related to the evolution of mating preferences and methods for the quantification of selection. More information about Jono can be found on his website.


University of Idaho (2017-): Alexa Small (2018-2019), Ian Carlson (2019), Brooke Butters (2019), Cory Hendrickson-Rose (2018-2020), Jennell Johnson (2019-2020).

Texas A&M (2004-2017): Caitlin Gabehart, Erin Dooley, Paul Hale,  Madelyn Esquivel, Elvira Maynard, Andrea Martinez, Keren Herrera, Caitlin Leslie, Magan Currie, Vivian Thomas, Alex Saucedo, Kevin Records, Sarah Yun, Cristin Harper, Danielle Schroeder, Liz May, Vanessa Seyle, Brandon Fordham, Randall Carter, Sarah Gaughan, Lauren Hamilton, Ryan Whitmer, Chester Wu, Megan Thompson, Andrew Coronado, Jason Shurb, Cristina Alvarez, Loren Mendoza, Zach Cress, Kathlyn Sanchez, Zack Falgout, Stefan Gilthorpe, Charlotte Ellis, Muhammad Arian, Tessia Lamison, Amanda Strickland, Nicole Strickland, Billy Martin, and Courtney Passow.

Georgia Tech (2002-2004): Kristen Marhaver, Melanie Raimondo, John Dooley, James Cellini, and Tremaine Knighten.
