Dr. Voss’s primary areas of interest include shallow and mesophotic coral reef ecology, coral health and disease, molecular ecology, and marine conservation and management. Through Harbor Branch’s Robertson Coral Reef Program and the NOAA Cooperative Institute for Exploration, Research, and Technology, he works to discover, characterize, and protect coral reefs ecosystems. He has completed over 1000 scientific dive and led more than 30 scientific expeditions primarily in the Bahamas, Florida Keys, Dry Tortugas, and Gulf of Mexico with additional investigations in Panama, Belize, Curacao, Bonaire, Dominica, USVI, and St. Eustatius. Dr. Voss teaches undergraduate courses in the Harbor Branch Semester by the Sea Program, graduate courses in the FAU Department of Biology, and molecular workshops for high school students. He also serves on various committees including the South Atlantic Fisheries Management Council Coral Advisory Panel, the Florida Keys National Marine Sanctuary Technical Advisory Committee, and FAU’s Diving and Boating Safety Committee. After growing up on the beaches of central Florida, Voss attended Elon University in North Carolina and completed a B.S. in biology along with minors in philosophy and chemistry. He earned his Ph.D. in biological sciences at Florida International University in Miami, and was a member of the marine science faculty at Eckerd College in St. Petersburg before accepting his current position at Harbor Branch.

Danielle is a Masters student who joined the lab in August 2015 and is doing research on gene expression in relation to the St. Lucie Reef Project. She is a recent graduate of the University of Delaware with a degree in Environmental Science and a concentration in Marine Science. Her interest in coral reef ecosystems sparked during participation in a field methods research program on Little Cayman Island where she became an AAUS Scientific Diver, NAUI Rescue Diver and participated in coral abundance and diversity research. Working as a research assistant in an Algal Physiology research group during her undergraduate, Dani investigated the genetic effects of thermal stress and ocean acidification on coral algal symbioses. She recently spent her summer in Key West teaching marine education with Reef Relief , a non-profit membership organization aimed to protect and improve coral reef ecosystems.

 

Jennifer Polinski

jpolinski2014@fau.edu

 

Jennifer Polinski joined the lab as a Masters student in August of 2014. Her thesis research focuses on the coral-Symbiodinium symbiosis in mesophotic coral reefs (>30m) in the Gulf of Mexico . For her thesis, Jennifer will characterize the zooxanthellae assemblages found in Montastraea cavernosa through classical measures of abundance and pigment content as well as through genetic identification using next generation sequencing. In additional to characterizing these assemblages, she will compare them to symbiont assemblages from neighboring shallow reef ecosystems. Prior to joining the graduate program, she volunteered in the lab during the summer of 2013 and worked as an intern during the summer of 2014, doing research in conjunction with the St. Lucie Reef Project . In May of 2014, she completed her B.A. in Biology and Mathematics at Albion College  in Albion, Michigan. After completing her degree at HBOI, she intends to pursue a Ph.D. and a career in research and academia.

 

Alycia Shatters

ashatters2014@fau.edu

 

Alycia Shatters is a Masters student who joined the lab in January of 2014. She completed her B.A. in Biology at New College of Florida, where she worked on creating a protocol to isolate high quality DNA from recalcitrant tissues such as R. mangle. Afterward she spent two years with the Peace Corps spreading awareness of environmental conservation to the youth living in the Amazon Rainforest. As part of her Master’s thesis research, she helped design an ex-situ system in which environmental variables can be controlled in order to test the effects of discharge water from Lake Okeechobee and manmade canals in South Florida on corals and their symbionts.

 

Michael Studivan

mstudiva@fau.edu

 

Mike is a Ph.D. candidate who joined the lab in August of 2012. His dissertation research examines the ecology and genetic connectivity of mesophotic coral reefs (>30m) and the interaction of environment and genotype on coral morphological adaptation to depth. Mesophotic reefs have been under recent research attention with their increasing discovery near shallow reefs, in part due to their benefits as fish habitats. His dissertation research will address key questions regarding mesophotic reefs using Montastraea cavernosa from the Gulf of Mexico (Flower Garden Banks and Pulley Ridge) and the Caribbean (Carrie Bow Cay, Belize). (1) How well are MCEs connected to shallow reefs? (2) How do shallow and mesophotic conspecifics differ in gene expression and corallite morphology? (3) Can corals adapt their morphology and gene expression to match changing environmental stimuli? Mike’s dissertation will test these questions using a combination of molecular techniques (microsatellites and RNASeq) and a reciprocal transplant experiment to assess connectivity, phenotypic plasticity, and gene expression responses of mesophotic corals. Prior to his graduate work at Harbor Branch, he completed his undergraduate degree at St. Mary’s College of Maryland with a senior thesis describing the effects of oil dispersant exposure on soft coral Xenia elongata bleaching (now published). He then worked at the Chesapeake Biological Laboratory identifying Arctic benthic invertebrates for climate change and petroleum exploration research. He is a technical diver with certifications from GUE, AAUS, TDI, PADI, and PSI/PCI. He also has six years of video editing experience and has been producing outreach videos for the lab.
