Adam Gormley, Ph.D., describes himself as a creative and adventurous person—albeit, not creative in the traditional sense. “Science allows me to be creative; to me, it’s a form of art. I love being outdoors, going on sailing trips, and spending time adventuring with my family. Research is the same—it’s an adventure. My creative and adventurous sides have combined into a real love for science,” he says. Dr. Gormley currently channels his passion for science into his position as an assistant professor of biomedical engineering at Rutgers University in Piscataway, New Jersey.

Learning How the World Works

Both of Dr. Gormley’s parents worked in science and medicine—his mother as a medical doctor and his father as a physician-scientist—and they instilled in him a curiosity for how the world worked. When he was young, Dr. Gormley and his parents would tinker with cars or boats and fix broken household items together, all the while talking about the individual parts and how they functioned as a whole. “I always had that technical, hands-on side of me,” he says.

When she started college, Anne Carpenter, Ph.D., never guessed she’d one day create software for analyzing images of cells that would help identify potential medicines and that thousands of researchers would use. She wasn’t planning to become a computational biologist, or even to focus on science at all, but she’s now an institute scientist and the senior director of the Imaging Platform at the Broad Institute of Massachusetts Institute of Technology (MIT) and Harvard in Cambridge.

Starting Out in Science

Before beginning her undergraduate studies at Purdue University in West Lafayette, Indiana, Dr. Carpenter’s strongest interests were reading and writing. Then, her subjects expanded. “In college, I liked science as much as anything else, and I realized that was unusual, as a lot of other people really struggled with it. I decided to pursue science because I enjoyed it and the field had good job prospects,” she says. Dr. Carpenter majored in biology because she felt it had the “juiciest questions” as well as a direct impact on human health.

“Being a researcher is special because there aren’t many jobs that allow you to spend the majority of your time thinking about the things you find the most interesting in the whole world,” says William Ratcliff, Ph.D., an associate professor of biological sciences and the director of the interdisciplinary graduate program in quantitative biosciences at Georgia Institute of Technology (Georgia Tech) in Atlanta. We talked with Dr. Ratcliff about his career path, research on yeast, and advice to budding scientists.

Q: How did you first become interested in science?

A: My family owns land in Northern California that has been passed down for more than 100 years. When I was a child, my brother and I would spend summers on that land getting lost in the woods. We would really see the forest for its parts: seeing how organisms interacted with one other, tracking stages of development, and listening to birdcalls. My grandmother would identify plants by their scientific names, and we’d discuss their reproduction strategies. We became amateur natural historians during those summers. Perhaps it’s no surprise my brother and I both got Ph.Ds. in biology.

“I have a hard time envisioning a career more exciting than science. It’s really magical to see an experimental result and, for a moment, be the only person in the universe to know something about the world,” says Markita Landry, Ph.D., an associate professor of chemical and biomolecular engineering at the University of California, Berkeley. In an interview, Dr. Landry shares with us her scientific journey, research with nanoparticles, and interests outside of the lab.

Q: What sparked your interest in science?

A: I was indirectly exposed to science growing up because my mom was in computer science, but I think moving to the United States is what made me very interested in it. My mother is Bolivian; my father is French-Canadian; and I grew up mostly in Quebec, Canada. When I was halfway through high school, we moved to the United States, and, for the first time, my classes were taught in English. I really gravitated to math and science because they made sense regardless of the language they were taught in.

Sometimes we can be our own worst enemies without even realizing it. One devastating example is sepsis: our body’s overwhelming or impaired immune response to an insult—usually an infection or an injury to the body. According to the Centers for Disease Control and Prevention
(CDC), sepsis affects at least 1.7 million people in the United States each year, and it can lead to tissue damage, organ failure, and death. (See our sepsis fact sheet for more information.)

An outline of the United States composed of people icons, above text that reads: “Get ahead of sepsis. Know the risks. Spot the signs. Act fast.” Next to the map outline is text that reads: “At least 1.7 million adults in the U.S. develop sepsis each year, and nearly 270,000 die as a result.

In Other Words: Not All Cultures Are Human

by
0 comments

The word culture may make you think of a flag, style of clothing, celebration, or some other tradition associated with a particular group of people. But in biomedical science, a culture is a group of cells grown in a lab. Scientists use cultures to learn about basic biological processes and to develop and test new medicines.

Below the title “Culture: In Other Words,” two images are separated by a jagged line. On the left are outlines of faces surrounding a globe of the Earth. On the right is a hand holding a Petri dish with cells growing in it. Under the images, text reads: “Did you know? In biomedical science, a culture is a group of cells grown in a lab.”

The Birth of a Culture

Scientists can grow many types of cells as cultures, from bacteria to human cells. To create a culture, a researcher adds cells to a container such as a Petri dish along with a mix of nutrients the cells need to grow and divide. The exact recipe varies depending on the cell type. (Because many lab containers were historically made of glass, researchers sometimes refer to studies that use cultures as in vitro—Latin for “in glass.”) Once the cells multiply and fill their container, researchers split the culture into new containers to produce more.
