Juliana Ansari is a laboratory supervisor with a predilection for probiotics. At Fairfield University, Juliana coordinates instructional biology labs and runs a research program with undergraduates. As a laboratory supervisor, Juliana designs lab activities, makes media, and maintains bacterial cultures and live animal collections.
Microbiologist Amanda Gunn takes on something unusual for a microbiologist; she started a fish research and community lab. When Amanda came to Grays Harbor College as a faculty member, she wanted a way to fit her work into the needs and culture of the community. “Everybody here hunts or fishes, and it seemed like a good way to get the community interested in science,” Amanda says. Thus, Fish Lab began.
Fish Lab is a volunteer-based program intended to both restore and monitor the waterways in the area and to get the community involved. Amanda holds volunteer Fish Lab hours twice a week where students and community members can participate in water quality analysis, trail work, dissections, and more. (more…)
Hi everyone. Thank you for following along on tales of the fascinating lives of microbes. For the next six weeks, I will be broadening my writing and tackling other fields of biology as the summer science writer at the Marine Biological Laboratory (MBL). Today, I was working on a story about sex change in snails and tomorrow I will be interviewing a cephalopod expert! In the meantime, please follow along on MBL's blog The Well for some of the stories I am working on. I will not be posting about strictly microbiology stories here for a while, but don't fret, I will still share "Meet a Microbiologist" stories every other week as scheduled.
Like many young scientists, Kimberly Walker took to her natural surroundings for study. As a child, she would do experiments on ants near her house. After a B.S. in medical technology, she pursued a Ph.D. in microbiology and immunology. She studied the molecular pathogenesis of Gram-negative bacteria, specifically Bordetella pertussis, Proteus mirabilis, and diarrheagenic Escherichia coli.
She is fascinated by the secretion systems of Gram-negative bacteria. Gram-negative bacteria use different forms of secretion to transfer proteins from within the cell to the exterior. Secretion systems have many functions, whether to emit toxins or to build extracellular structures. “They are brilliant. Type II is my favorite,” she says. (more…)
