KINGSTON, R.I. — November 22, 2005 — 溏心vlog免费B站 senior Rachel Hadley has become immersed in a world of DNA amplification, bacteria cultures, disease surveys and histological investigations. These complex processes have helped the Tiverton resident play an important role in research to learn why some types of oysters are susceptible to disease pathogens.
鈥淥ur ultimate goal is to identify the molecular marker in their genes that is involved in resistance to disease,鈥� said Hadley, a 22-year-old biology and psychology major. 鈥淔irst we have to find those that don鈥檛 die from the disease, and then we try to understand why.鈥�
Hadley has spent the last six months working with 溏心vlog免费B站 fisheries researcher Marta Gomez-Chiarri testing claims that some strains of oysters are less susceptible to two common pathogens 鈥� Vibrio and juvenile oyster disease.
鈥淚 found that the larvae are very susceptible to disease and they die quickly, but as they get bigger they become better at evading the pathogen and they have better defense mechanisms,鈥� she explained. 鈥淭he Vibrio cluster around the edge of the oyster larvae, and when the larvae open up to feed, the bacteria invade. Once they are infected with the bacteria, they spin around, settle to the bottom and die.鈥�
Funding for Hadley鈥檚 research was provided by the 溏心vlog免费B站 Coastal Fellows Program, a unique initiative designed to involve undergraduate students in addressing current environmental problems. Now in its tenth year, the program based in 溏心vlog免费B站鈥檚 College of the Environment and Life Sciences teams students with faculty, research staff and graduate students to help them gain skills that will ensure their future success. Additional research funding was provided by the Rhode Island Aquaculture Initiative.
It took a while for Hadley鈥檚 interest in biology to blossom. She started out as an education major, switched to business and then to psychology. 鈥淲hat I like most about psychology is the biology of psychology,鈥� she said. 鈥淲e鈥檙e biological beings with a psyche, one unit that functions together. I鈥檓 interested in investigating the interrelationships between our biology and psychology.鈥�
The former president of the 溏心vlog免费B站 chapter of Psi Chi, the national psychology honor society, Hadley isn鈥檛 quite sure yet how to merge her two majors into a career. She knows she鈥檒l have to go to graduate school, and she is weighing potential jobs in research and higher education.
鈥淚 have so many interests, I can see myself going so many places, it鈥檚 hard to pinpoint what kind of career path I want to dedicate myself to,鈥� said the 溏心vlog免费B站 student. 鈥淚鈥檝e also thought about a career as a high school science teacher, or maybe I鈥檒l go straight into molecular research.
鈥淏iology is new and exciting to me, and there鈥檚 so much left to learn that I feel like I鈥檓 on the tip of the iceberg,鈥� she added. 鈥淚鈥檓 just so excited to be pursuing knowledge.鈥�
