#GradStudentLife – A GPMB Student Profile

Ever wonder what students do while working toward a Master of Science in Marine Biology?
Of course there are the classes, labs, tests, seminars, papers, work, studying, networking, etc…add in sample and data collection, data analysis, etc…oh yeah, and then there’s the thesis and defense!

Keilin Gamboa-Salazar is a third-year GPMB student getting ready to finish up the program and shared her research and goals with us.

Keilin is our resident international student from Costa Rica and works in the Reef Fish Section of the SCDNR. Her research focuses on the reproductive biology of Gag and Scamp Grouper. She is investigating the relationship between the number of egg-batches spawned per female, and the age and size of the fish. In addition, she is modeling the probability of spawning for a female, influenced by the age or size of the fish, as well as  any associated environmental variables. This information will shed light on what variables can influence spawning with the ultimate goal of having a better understanding of the reproductive output of the fish stock, and incorporating this knowledge into the regional stock assessments. Keilin first got interested in this research because of the possibility of finding information which would lead to actual change in the way that fisheries are managed, and in that way have an impact on ocean conservation. When not looking through a microscope, Keilin highly enjoys going on research cruises up to 100 miles offshore, where you can see absolutely nothing but water in the horizon. She also enjoys getting to play with all sorts of fishes, and other critters when processing the samples for the Reef Fish lab. She hopes to develop a career in the fisheries which involves offshore cruises, with the ultimate goal of working for the conservation of the oceans. Keilin is currently working on finishing data analyses and writing her thesis, so look out for a thesis defense announcement in January!

SCDNR Open House 2017

The SCDNR Open House was this past Saturday, October 21. Every two years SCDNR invites the public to meet and talk with marine biologists, fisheries managers, and educators at the Marine Resources Center plus their partners at the College of Charleston, Hollings Marine Lab, NIST and NOAA.
Guests learned about marine science with informational booths as well as tutorials, tours, crafts and fun family-friendly activities.
We are happy to be a partner for this event and had a great day meeting the community!

GPMB students hosted a touch tank and offered fun crafts for the kids.

GPMB students also had a bake sale and raffle to raise funds for the MBGSA in support of student travel for conferences and events.

Guests were invited inside to see some of the resources of the lab and experience hands-on activities.
Faculty and students presented preserved sharks and fish, live plankton samples and the entire collections room of over 100,000 preserved fish and invertebrate specimens!

Thanks to everyone who made the event a success! It was a great day and we are already looking forward to the next one!

21st Annual Student Research Colloquium

The 21st Annual Student Research Colloquium was held on September 23, 2017. We had another successful event with oral and poster presentations from our Graduate Program in Marine Biology students as well as a graduate student from The Citadel.

Presentations were followed by the keynote address given by Dr. Billie Swalla, Director, Friday Harbor Laboratories, Washington University.

The event was closed with a Lowcountry Boil and introduction of the new GPMB students.

The purpose of the colloquium is three-fold:

  • It gives students the opportunity to present their research in a professional setting and receive feedback from judges and audience members.
  • The presentations are a showcase of the research activities performed by GPMB students and faculty affiliated with the program.
  • Finally, the colloquium is an opportunity for students and faculty to interact and talk about the research activities they are interested in.

You can view the full program, including presentation abstracts here.

2017 Fort Johnson REU Program

Grice Marine Lab hosted ten students for the 2017 Fort Johnson Summer Research Experience for Undergraduates (REU) Program. They arrived May 31st, hit the ground running, worked for ten weeks, and closed the program with exceptional presentations on August 9th. Each intern was paired with a mentor on the Fort Johnson campus to develop and execute a research project on the program theme of “Marine Organism Health: Resilience and Response to Environmental Change.” Along the way, the interns learned how to share their research in weekly workshops on science communication led by Carolyn Sotka. The program also included lectures, field trips and professional training for careers in science.

Twenty-six CofC Undergraduate Co-authors

DirtMcgirt phage

As part of the HHMI Science Educations Alliance Phage Hunters Program, twenty-six College of Charleston undergraduate student were published November 27, 2013 in the recent Genome Announcement.  This publication includes two published NCBI Genome Accession Numbers.  Hyperlinks to genome accession numbers are within attached paper (Genome Announc.-2013-Hatfull-). Many of these students worked with Dr. Ana Zimmerman here at the Grice Marine Laboratory. Dr. Erin Morris-Richard and Dr. Chris Korey from the downtown campus also worked on this project. The project website lists details of the phages found. With phage names like DirtMcgirt (pictured) and FuzzyWuzzy you should take a look at the wonderful research these students are doing.

New Molecular Core Facility Manager

Kristy Hill

Kristy Hill is the new lab manager for Grice Marine Lab’s Molecular Core Facility. She is originally from Greensboro, NC, and she and her fiancé are new to the Charleston area. After receiving her Bachelor of Arts in Environmental Science and Policy and Music at Duke University, she was a technician at the Virginia Institute of Marine Science.

She is excited to be at Grice and is looking forward to assisting faculty, staff, and students apply molecular methods to explore their various research questions. Please call or email her if you are interested in finding out how the Molecular Core Facility might be able to help you. After she finished her Masters, she was a research assistant in the Fisheries Genetics Lab with Drs. John Graves and Jan McDowell, where she worked on the population genetics of fishes, such as rays and spearfishes, using microsatellite markers. She most recently worked at the Smithsonian Institution on a project exploring the diversity of marine bivalve parasites along a latitudinal gradient—from Panama to the Mid-Atlantic, US—using standard molecular diagnostic methods as well as metagenomic methodology Lab with Drs. Gene Burreson and Ryan Carnegie. This experience sparked her interest in using molecular tools to answer ecological questions. After three years, she went back to school and completed her Masters in Marine Science at The College of William and Mary, where she was advised by Drs. Gene Burreson and Kimberly Reece. Her thesis project involved assessing the diversity, molecular phylogeography, and dispersal of a genus of protistan parasites of oysters (Bonamia spp.).
