Dr. Jose (Joe) Lopez has been a Professor at the Nova Southeastern University since 2007. He earned a Master’s degree at Florida State University, and his doctorate at George Mason University studying the evolution of mitochondrial DNA and its transpositions (Numt) in feline nuclear genomes which fit into the “serial endosymbiosis theory” of cellular evolution. Dr. Lopez then took on postdoctoral fellowships at the Smithsonian Tropical Research Institute (STRI) in Panama to study corals, and sponge genetics at Harbor Branch Oceanographic Institute. Professor Lopez participates in a number of genomics-based projects. For example, he co-founded the “Global Invertebrate Genomics Alliance”, which applies whole genome sequencing of non-model invertebrate species, and also dovetails with the Wellcome Sanger Institute’s Aquatic Symbiosis Genome Project. Dr. Lopez also currently serves on the governance committee for the Earth Biogenome Project (EBP), which aims to sequence 1.5 million eukaryotic organisms over the next 10 years. To characterize factors involved in water quality, his laboratory’s microbiome research recently focused on high throughput analyses of the meta-transcriptomes and metagenomes of cyanobacterial bloom communities in the Lake Okeechobee watershed, Port Everglades Inlet seawater and sediments and deep-water microbiomes in the Gulf of Mexico via DEEPEND (Deep Pelagic Nekton Dynamics of the Gulf of Mexico). Dr. Lopez has recently authored the book, Assessments and Conservation of Biological Diversity from Coral Reefs to the Deep Sea: Uncovering Buried Treasures and the Value of the Benthos (Academic Press).

Andrew is an Assistant Professor at Nova Southeastern University (NSU) where he runs the Reef Ecology, Ecosystems & Functions Lab (REEFs). He is also a Principal Investigator within the National Coral Reef Institute (NCRI) within the Department of Marine and Environmental Sciences. Originally from Ohio, Andrew has spent the past 20 years working on coral reefs across the Indo-Pacific (Australia, Singapore, Philippines, Papua New Guinea, Malaysia, and the Middle East). The central theme of his research is exploring broad-scale ecological processes that structure coral reef ecosystems under the overarching themes of climate change, disturbance, human use and resilience. He has worked extensively on the ecological ramifications of extreme environmental conditions on corals and reef fish communities. He has assessed the impacts of global change on coral reefs, and examined processes and mechanisms by which coral communities may recover and adapt, and how this can be incorporated into, or influenced by, management action. Increasingly, a core focus of his research has been quantifying ecological functions that promote or erode resilience on coral reefs, and how human activities influence reef functions.

I am a marine ecologist and molecular phylogeneticist who uses the interspecific interactions of invertebrates to examine questions of symbiosis evolution, the evolution of functional form, the role of symbiosis in promoting and maintaining biological diversity, and the effects of climate change on the ecology of symbiotic associations. I use an integrative approach to my research and collaborate with diverse groups of colleagues, students, and professionals ranging from artists to engineers. A significant portion of my research focuses on tropical reef corals (Scleractinia) and zoanthideans (Zoanthidea), and their associated photosynthetic dinoflagellate symbionts (Symbiodiniaceae) and invertebrate hosts. While the Scleractinia-Symbiodiniaceae symbioses are predominately found in shallow tropical waters, the Zoanthidea/invertebrate symbioses are global and include at least six invertebrate phyla in most major benthic habitats ranging from intertidal mud flats to the deep-sea.

I am a marine scientist focused on tropical coastal marine ecosystems. Through the lens of biogeochemistry, I examine interactions between seawater chemistry and benthic communities, aiming to understand coastal carbon cycling and the influence of climate change on coral physiology and ecology. My research centers on Caribbean coral reefs and seagrasses where global stressors such as warming, acidification, and deoxygenation have significant impacts. My background in hands-on conservation includes coral spawning, assisted fertilization, and larval rearing for restoration efforts. Collaboration with local communities and citizen scientists is at the core of my work, and I am committed to support and promote equity, diversity, and inclusion in marine science.

Postdoctoral Research Fellow
I am fascinated by the influence of environmental conditions on coral holobionts and their associated microbial communities. My research seeks to understand how different symbiotic interactions promote the stability and resilience of marine organisms.
I obtained my B.Sc. in Marine Sciences at the Ruppin Academic Center ( Mikhmoret Israel). This was my first exposure to marine sciences and, at that early stage of my academic studies, I realized I am most passionate about this discipline. Thereafter, I enrolled in the School of Zoology at Tel Aviv University where I obtained my M.Sc. under the supervision of Prof. Yehuda Benayahu. I conducted my Ph.D. studies at the same school under the joint supervision of Prof. Yehuda Benayahu and Prof. Dorothée Huchon. In my dissertation, I incorporated genetic, ecological, and physiological methods to address the hypothesis that environmental parameters, including depth and climate-change scenarios, affect essential life history traits of zooxanthellate octocorals in the Gulf of Aqaba (northern Red Sea).
My work at NCRI aims to characterize the ecosystem services provided by Florida’s octocoral forests. I combine field surveys, photographic data collections, and computational analysis techniques to examine morphological features and biotic associations within octocoral forests. Additionally, using molecular tools, I identify the associated microbial assemblages and describe their dynamics across spatial and temporal scales.

I am a coral reef ecologist and molecular evolutionary biologist from Colombia, specializing in coral conservation and evolution within the Caribbean. I received my B.Sc. in Marine Biology from Universidad Jorge Tadeo Lozano (Colombia), followed by an M.Sc. in Biological Sciences at Universidad de Los Andes (Colombia) under the mentorship of Dr. Juan Sánchez. I later earned my Ph.D. in Environmental and Biological Sciences from the University of Rhode Island (USA), working with Dr. Carlos Prada.
My research spans diverse topics, including using benthic foraminifera as indicators of water quality on coral reefs and investigating the population genomics and phylogenomics of corals. I focus on how coral species adapt and diverge across environmental gradients, such as depth and temperature, and their physiological responses to bleaching events.
Currently, as a Postdoctoral Fellow at the National Coral Reef Institute (NCRI) under Dr. Joe Lopez, I am exploring transcriptomic variations in soft corals along the Florida reef tract. This research examines how gene expression correlates with environmental shifts. Ultimately, I aim to leverage molecular tools to study coral evolution and resilience, with the goal of informing conservation strategies that protect reefs in the face of global climate change.
