Brianna (Galbreath) Chilton
Ph.D. Candidate
bgalbreath1@student.gsu.edu
Brie graduated with her Bachelor of Science in wildlife and fisheries biology from The University of Georgia. In her work researching wildlife and zoonotic diseases, she discovered the microscopic world of organisms known as microbiology. She completed her Masters of Science in applied and environmental microbiology from Georgia State University in December 2017 and was fortunate to earn a Ph.D. position upon completion. Her research in lab deals with evaluating the stability and activity of enzymes from Rhodococcus rhodochrous DAP 96253 with targeted uses for the bioconversion of acrylonitrile to bioacrylamide and for the novel therapeutic treatment of acute lymphoblastic leukemia (ALL). Outside of the lab, Brie is involved in the fermentation of beer and bread, wildlife conservation, and STEM education outreach focused on K-12 grades. Her hobbies include various arts, traveling, kayaking, and sailing with her husband and dog. You can follow her science on Instagram and Twitter at MicroBrieology.

Marilyn Millett
Master Student
mmillett1@student.gsu.edu
Marilyn is currently investigating the effects of metal co-factors on enzymatic activity in Rhodococcus rhodochrous DAP 96253 via batch-fed fermentation. Prior to joining the lab, she was enrolled in a CURE lab here at Georgia State where she studied the synergistic effects of Zingiber officinale (commonly known as ginger) on the antibiotic sensitivity of soil-dwelling microorganisms. She holds two Bachelor of Science degrees, one in Psychology with minors in Classics and Biochemistry from The University of Arizona, with the other in Biology from Georgia State.
Outside of the lab, Marilyn enjoys interacting with undergraduate students as a biology tutor/TA and driving her Jeep Wrangler with her Shar Pei/Dalmatian mix, Flapper. After obtaining her master’s, she hopes to do more research in microbial ecology and eventually earn a PhD.
Research Focus:
Batch-Fed Fermentation, Enzymatic Induction
Paul Amos
Master Student
pamos3@student.gsu.edu
The current asparaginase-based treatment for Acute Lymphoblastic Leukemia in juveniles is isolated from recombinant Gram-negative E. coli expression. Endotoxin removal from products produced by Gram-negative organisms present challenges in proteins used in medical treatment and are required to meet FDA standards.
Paul works on producing endotoxin-free asparaginase from Rhodococcus rhodocrous strain DAP 96253, a Gram-positive soil-based organism, which was shown to produce nitrile hydratase with asparaginase activity when induced.
Research Focus:
Asparaginase, Nitrile Hydratase
Fortino Pineda Veloz
Master Student
fpineda2@student.gsu.edu
Fortino conducts molecular studies on Rhodococcus rhodochrous DAP 96253 relating to the nitrile hydratase enzyme. He employs techniques including DNA extraction, Gel Electrophoresis, and Matrix-Assisted Laser Desorption/Ionization Time of Flight (MALDI-TOF) Mass spectroscopy in his studies. Upon characterization of nitrile hydratase, his focus is to identify molecular factors that may improve its catalytic efficiency.
Fortino also conducts external independent research in bioinformatics. His project analyzes biomarkers to assess the microbial condition of Jamaica Bay, NY using the QIIME2 pipeline. He hopes his prospective career will use biological data science to identify issues to which his molecular approaches may solve.
Research Focus:
Nitrile Hydratase, MALDI-TOF, Molecular Biology
Arthur Dasouza, Jr.
Master Student
adasouza1@student.gsu.edu
Outside of the lab Arthur enjoys producing music, painting, and writing poetry.
Research Focus:
Delayed Fruit Ripening, Antifungal
Parker Lowe
Master Student
plowe6@student.gsu.edu
Parker received his bachelor of science degree from Clemson University where he studied genetics. Parker did research in the senescence of maize and the genes that contribute to pre-senescence.
Parker is now studying the activity of asparaginase in Rhodococcus rhodochrous DAP 96253, and the effectiveness of the asparaginase derived from Rhodococcus rhodochrous DAP 96253 on leukemia cell lines.
Research Focus:
Asparaginase, Genetics
