High School Student Designs Website to Educate Public on Great Barrier Reef and Climate Change
Alison Whitehead, a student at Marriots Ridge High School in Marriottsville, MD, is trying to educate the public on the impact climate change will have on the Great Barrier Reef. As part of a class project, she has completed a research paper and a website to be presented at an environmental conference. Over the past few months, Dr. Dixson has served as a resource and expert on the topic. To see Ali's website click here.
Post-doc Position Available in Marine Microbiome Research
March 31, 2015
Dr. Frank Stewart & Dr. Danielle Dixson are looking for a postdoctoral fellow to study the microbiome of coral reef fishes. The postdoc will work jointly with both professors to understand the diversity and evolution of the reef fish microbiome and its role in fish health and ecology. Ideal candidates should have a Ph.D. emphasizing microbiome and/or symbiosis research. Additionally, knowledge or background in marine biology and microbial evolution is desirable. The position is targeted to begin in late summer/fall 2015 with funding available for two years pending satisfactory first year progress. Find more information on the position and application here.
Dr. Dixson Featured in Georgia Tech Research Horizons
March 26, 2015
Dr. Dixson's research was recently part of a feature focusing on Georgia Tech's Faculty Explorers. In the article, Dr. Dixson discusses some of the adventures that have arisen while working in remote places - such as getting stung in the leg by lionfish. The article also features photos from her time at the Carrie Bow Cay Field Station in Belize where she was study coral larval recruitment.

Congratulations to Dr. Dixson on becoming a Sloan Research Fellow!
March 05, 2015
The Sloan Research Fellowships seek to stimulate fundamental research by early-career scientists and scholars of outstanding promise in the U.S. and Canada. These two-year fellowships are awarded yearly to 126 researchers in recognition of distinguished performance and a unique potential to make substantial contributions to their field. Since 1955, Sloan Research Fellows have gone on to win 43 Nobel Prizes, 16 Fields Medals, 65 National Medals of Science, 14 John Bates Clark Medals, and numerous other distinguished awards.

The Dixson Lab welcomes William Feeney through the 2015 Fulbright Postdoctoral Scholarship
February 05, 2015
William Feeney is a Postdoctoral Research Fellow at the School of Biological Sciences, University of Queensland. He completed his PhD at the Australian National University, and held an Endeavour Postdoctoral Fellowship at the University of Cambridge. While working with Dixson at Georgia Tech, his research will focus on mutualistic interactions between coral reef fishes. In particular, he will investigate whether interspecies mutualisms predict resilience to a changing environment. For more information, visit this link.
Fish use chemical camouflage from diet to hide from predators
December 10, 2014
A species of small fish uses coral-scented camouflage to hide from predators, a new study has shown, providing the first evidence of chemical camouflage from diet in fish. “This is the very first evidence of this kind of chemical crypsis from diet in a vertebrate,” said Rohan Brooker, a post-doctoral fellow in the School of Biology at the Georgia Institute of Technology in Atlanta.

Reduced odor tracking in sharks as ocean acidification increases
September 10, 2014
These findings show that shark feeding could be affected by changes in seawater chemistry projected for the end of this century. Understanding the effects of ocean acidification on critical behaviors, such as prey tracking in large predators, can help determine the potential impacts of future ocean acidification on ecosystem function.
Marine protected areas might not be enough to help overfished reefs recover
August 21, 2014
Young corals and fish turned off by smell of damaged habitats
Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle.
“If you’re setting up a marine protected area to seed recruitment into a degraded habitat, that recruitment may not happen if young fish and coral are not recognizing the degraded area as habitat,” said Danielle Dixson, an assistant professor in the School of Biology at the Georgia Institute of Technology in Atlanta, and the study's first author.
