Dr. Jay R. RookerPosition:
Regents Professor & McDaniel Chair of Marine Fisheries
Texas A&M University at Galveston
Department of Marine Biology (Galveston)
Department of Wildlife and Fisheries Sciences (College Station)

Education:
Ph.D. University of Texas at Austin (1997)
M.S. University of Puerto Rico (1991)
B. A. Gustavus Adolphus College (1985)

Research Interests:
My research centers on the community and population ecology of aquatic organisms, with a special emphasis on marine fishes. I am particularly interested in linkages between habitat selection, individual responses, and survival. My work is both laboratory and field-based, and I typically use both quantitative and experimental approaches to elucidate the importance of biotic and abiotic factors that influence growth, condition, and survival. In addition, we are currently using a variety of natural markers to solve ecological problems. Otolith chemistry is being used to retrospectively determine the environmental histories of marine fishes. The premise of otolith chemistry is that certain elements or isotopes are incorporated into otoliths in proportion to their concentrations in the environment, and thus we use these elemental fingerprints to distinguish individuals from different environments or regions. We also use dietary tracers (stable isotopes, fatty acids) to investigate marine food web structure since consumer tissues reflect the isotopic and fatty acid composition of prey in a predictable manor. These natural biomarkers provide time-integrated or long-term measures of diet, and both approaches afford information on source(s) of organic matter supporting local food webs as well as trophic relationships of associated consumers. Recent work also involves the use of sophisticated electronic tags to investigate movement and population connectivity of coastal and pelagic fishes.

Position:

M.S. Student

Education:
B.S. The Ohio State University (2014)

Research Interests:
My research aims to investigate biodiversity and community structure of larval fish assemblages in the NGoM. Its purpose is to evaluate the value of the NGoM as a nursery habitat by identifying the geographic position and temporal dynamics of biodiversity hotspots as well as the oceanographic conditions associated with these areas. The research will establish baseline data on the distribution and abundance of larval fish and can be used to indicate changes in population dynamics through evaluating assemblages, ultimately aiding in the management and conservation of pelagic species.

Position:

M.S. Student

Education:
B.S. Texas A&M University (2005)

Research Interests:
I am interested in studying the life history and population dynamics of marine fishes. I have worked for the U.S. Army Corps of Engineers, Galveston District, Regulatory division as a Project manager since 2008.
 
Chris Steffen

Position:

M.S. Student

Education:
B.S. Texas A&M University (2016)

Research Interests:
I am interested in the small and large scale connectivity of marine fishes, with an emphasis on how it relates to wildlife management. I am currently studying the ingress and egress patterns of southern flounder (Paralichthys lethostigma) in Galveston Bay using acoustic telemetry. This will provide information about the timing of migration events, aiding in the identification of migration pathways and spawning time periods.
 
Jessica Lee

Position:
Research Associate

Education:
B.S. Texas A&M University (2012)

Research Interests:
I am interested in the life ecology of marine fishes and fisheries conservation. My research specializes in larval fish identification and otolith chemistry. I am currently focusing on the consequences of the DH oil spill on early life ecology and population dynamcis of pelagic fishes. In a separate study, I have used otolith chemistry to retrospectively determine the origin and spatial histories of bigeye tuna (Thunnus obesus) and yellowfin tuna (T. albacares) in the western and central Pacific Ocean.
Dr. Michelle Sluis

Position:
Postdoctoral Research Associate

Education:
Ph.D. Louisiana State University (2011)
B.S. Texas A&M University (2004)


Research Interests:
My research interests include eclolgy and population dynamics of marine fish, with an emphasis on conservation and management. My dissertation focused on examining variability in red snapper (Lutjanus campechanus) otolith microchemistry across the Gulf of Mexico (Gulf) to estimate population connectivity and mixing patterns.  Additionally, I also applied stable isotope and mercury tissue analyses on Lutjanid species to explore trophic differences and regional feeding strategies across the northern Gulf.  Currently, I am examining the early life ecology of blue marlin (Makaira nigricans) in the northern Gulf.

Position:
Postdoctoral Research Associate

Education:
Ph.D. Texas A&M University (2015)
M.S. University of West Florida (2007)
B.S. Auburn University (2004)

Research Interests:
The primary purpose of my research is to address scientific gaps in our understanding of population dynamics of aquatic organisms. My approach integrates elements of spatial ecology, geochemistry, and ecosystem modeling to address ecological questions related to animal movement and population connectivity. Using several complementary techniques I am able to identify habitat and population linkages at different spatial scales to better understand how spatial relationships and movement patterns influence population connectivity of aquatic organisms.
