Position: 
Project Manager for DEEPEND
Research Scientist

Education:
2012 M.S. Marine Science, College of William & Mary, Virginia Institute of Marine Science (VIMS)
2000 B.S. Marine Science, Coastal Carolina University

Research Interests:
I am currently the Project Manager for the DEEPEND Consortium (www.deependconsortium.org), which is a five year project funded by the Gulf of Mexico Research Initiative. As Project Manager, I organize field sampling activities, administrate program subawards, and organize consortium meetings and reporting activities. I also serve as a Research Scientist, assisting with deep-sea fish identification and distributional analyses. My main area of interest focuses on a group of deep-sea fishes called the swallowerfishes (Family: Chiasmodontidae). Their common name reflects their ability to swallow prey larger than themselves as shown in this image. My current work on this family focuses on the taxonomy, distribution, diet, and reproduction of the species collected from the Gulf of Mexico.

Position/Major: 
Research Assistant, Oceanic Ecology Lab, Seascape Ecology Lab, and Marine Microbiology & Genetics  Lab
Oceanic Ecology Lab Manager, DEEPEND Consortium

Education: 
2018 M.S. Marine Biology, Nova Southeastern University
2015 B.S. Environmental Science with minors in Marine Science and Spanish, University of Delaware

Thesis: Identification and spatiotemporal dynamics of tuna (Family: Scombridae; Tribe: Thunnini) early life stages in the oceanic Gulf of Mexico

Research Interests:
I am interested in researching poorly-studied species/communities because my goal is to provide information to the public and conservation/management efforts to help maintain populations and overall large ecosystems. For my thesis, I examined the identification, faunal composition, and spatiotemporal distributions of larval and juvenile tunas (Family: Scombridae) in the northern Gulf of Mexico (GoM) from 2010 to 2017. During my thesis, I developed a synthesis of the morphological characteristics used to identify the taxonomically challenging larval and juvenile tuna life stages. My thesis also increased the existing knowledge on the identification of juvenile tunas by identifying further resolution of species-specific body ratios of this life stage. Species-specific environmental preferences (e.g., salinity, chorophyll a, etc.) and seasonality were identified as the main drivers of tuna spatial distributions across the epipelagic GoM. Before starting at NSU, I interned in Dr. Mark Warner’s Algal Physiology Research Lab at the University of Delaware where I studied the growth patterns of various coral symbiodinium.

Currently, I am a Research Assistant and the Lab Manager in Dr. Sutton’s Oceanic Ecology Lab at NSU. I am continuing to work with the DEEPEND Consortium, investigating both tuna early life stages and deep-sea organisms. I helped Dr. Sutton lead DEEPEND’s DP06 research cruise in July (GoM, 2018) and a DEEP SEARCH cruise in September (Atlantic Ocean, 2018). I also manage the DEEPEND and NOAA NRDA ONSAP databases, manage sample collection/processing/storage, write and collate cruise reports, and participate in outreach/education activities. I am also mentoring the lab’s graduate students and volunteers. In Dr. Rosanna Milligan's Seascape Ecology Lab, I am continuing to conduct statistical analyses on DEEPEND data and researching life history traits used to identify solutions for creating functional groups of deep-sea fishes for ecosystem management purposes. Additionally, as a member of Dr. Joe Lopez's Marine Microbiology & Genetics Lab, I manage The Photosymbiotic Hub's database, sample collection and preservation, and shipment/tracking of our specimens for the Aquatic Symbiosis Genomics Project.

Education:
2016 M.S. Biological and Environmental Sciences, University of Rhode Island
2013 B.S. Biology, Regis University

Research Interests: 
My research focuses on examining the morphology of sensory systems in deep-sea fishes. I am interested in understanding how fishes living in extreme environments, like the light-limited midwaters of the deep sea, interact with their environment. By studying the morphology and functional capabilities of sensory systems, we can infer how different species behave (i.e. find food, locate mates, and avoid predators).

Education:
2015 B.S. Marine Science, Biology Minor, Florida Gulf Coast University

Research Interests: 
I am interested in the taxonomy and classifications of fishes. Taxonomy is an ever-changing field, yet it serves as the groundwork for building various types of models used to monitor ecosystems. Classification methods/dichotomous keys are available for easily accessible species unlike deep-sea fishes and more specifically, juveniles. For this reason, I will be examining juvenile scorpaenids in order to create a dichotomous key for these undescribed life stages and will further investigate their spatial distributions for my thesis. Before studying at NSU, I interned at the FWRI satellite location in Port Charlotte, FL. I examined the diet composition of the common snook (Centropomus undecimalis) from two different populations in Charlotte Harbor.

Education: 
2017 B.S. Major: Biology, Environmental Studies Minor, Manchester University

Research Interests: 
I am interested in the ecology of deep-sea fishes and their habitat as well as potential conservation efforts. I am studying the spatial distribution of the genus Cyclothone, which are small, bristlemouth fishes, in the Gulf of Mexico. Although these fishes are known for their high abundance in trawls from waters across the globe, their distribution in the Gulf of Mexico is poorly described. Upon analysis of their morphological features and spatial distribution in the water, I aim to provide baseline information in order to observe changes in their distribution and abundance over time. Before attending NSU, I studied at Manchester University where I received my bachelor’s degree in Biology with a minor in Environmental Studies.
