My lab is fundamentally interested in the evolution of marine invertebrates with an emphasis on decapod crustaceans. We use morphological and molecular techniques to address questions related to their relationships, origins, biogeography, biodiversity, ecology, taxonomy, and conservation. My main research objectives include 1) decapod phylogenetics and genomics, 2) the evolution of systems and structures (ex. bioluminescence, vision, color), and 3) the identification of key morphological traits that promote diversification and speciation within this group.

The CRUSTOMICS Lab celebrates cataloguing its 10,000th crustacean specimen! With records dating back nearly 75 years, this milestone accomplishment is one to remember!
The CRUSTOMICS Lab welcomes its newest graduate student, Robert Tomasetti! His research is seeking to investigate coral reef connectivity by evaluating global marine algal biodiversity.
The Bracken-Grissom Spring 2019 Potluck goes in the books as a crabtastic success! Delicious food, beautiful weather, and clawfully good company! It doesn't get any better than that.
Work it, Robb! You're really krillin it....
Long-time lab member, Charles Golightly, checks off his first goal of Spring 2019 with his acceptance into FIU's PhD program. He will continue his development as a researcher in the Bracken-Grissom Lab!

Congrats to undergrad Joan Glenny for being awarded the MARC U* Fellowship at FIU!
Congratulations to PhD candidate Laura Timm for being selected as a 2016 GOMRI Scholar AND winning 3rd place with her poster "Diversity and connectivity of a mesopelagic shrimp as proxies for ecosystem health and recovery in the Gulf of Mexico" at this year's FIU's Biosymposium!
Who needs winter holidays when you can go scout future research sites?
PhD candidate Jorge Pérez-Moreno and PhD student Robert Ditter have returned from jungle hiking and cave diving in the Yucatan, along with CRUSTOMICS friend Gergely Balázs (Eötvös Loránd University, Hungary).
PI HBG received an NSF grant to study the evolution of deep sea bioluminescence and vision with Megan Porter (University of Hawaii) and Tammy Frank (NOVA). Looking forward to some exciting research!
