Principal Investigator
Mercedes Burns (B.A. Biology, Macalester College; Ph. D. Evolutionary Biology, UMCP) began her faculty appointment at UMBC in 2017.
Ph.D. Students
Ryan Bacon (B.S. Biology, West Chester University, PA) is studying the geography of sexual conflict and the associated functional biogeography of reproductive structures.
Harper Montgomery (B.S. Biological Sciences/Biochemistry, UMBC) will explore the role of sexual conflict in reproductive and morphological diversification.

Lab alumni
Lian Jackson (B.A. & M.S. UMBC) studied dietary effects on glycosylation in orb-weaving spider aggregate silk.
Tyler Brown (B.S. UMCP, Ph.D. ’24, UMBC) studied sexual conflict and reproductive assurance and their roles in the maintenance of geographic parthenogenesis. Tyler is passionate about science communication and can be found at @NotASpider_ on Twitter. He is currently a postdoctoral researcher with Dr. Stellwagen at UNC Charlotte.
Jessica Diaz (B.S. Michigan State University, M.S. ICARE) studied biotic and abiotic correlates of oyster growth, including salinity and phytoplankton community diversity, in the Baltimore Harbor as part of the new UMBC ICARE program (icare.umbc.edu).
Emily Marinko (UMBC ’23) earned a Master’s degree at UNLV.
Dante Washington (’22) helped Ryan conduct a systematic review of research on reproduction of organisms in temperate and tropical biomes.
Hamed Hudhud (’21) helped to prepare a proteomic protocol for measuring glycosylation in arachnid glues.
Heather Mayberry (’21) prepared an annotated bibliography of topics relating to the evolution of sex, and contributed to study of post-translational modifications in spider silks.
Marina Fahim (’21) used flow cytometry to identify polyploid Japanese harvesters.
Ryan Gunnison (’21, below) is fascinated by Hymenoptera and parasitism and is studied social behavior in harvesters.
Fleurine Amouzou Guiffo (’20) studied early-developing harvester species Leiobunum flavum and L. ventricosum using morphological keys.
Zulekha Karachiwalla (’21) studied spermathecal morphology in Leiobunum using a variety of imaging and 3D modeling methods.
Mayukha Pakala (’19; M.S. Applied Molecular Biology ’20) used 3RAD sequencing to reconstruct the phylogeny of the L. vittatum group.
