Award-Winning Safety Training Videos Showcase Inclusivity in the Lab

by
0 comments

Virginia Commonwealth University’s (VCU’s) Center on Health Disparities and safety and risk management department in Richmond teamed up to develop a series of six lab safety training videos with supplemental funding to their NIGMS-funded Initiative for Maximizing Student Development (IMSD) program. The videos cover topics such as safety culture, biosafety, chemical safety, and emergency response, but what sets them apart is how they showcase diversity and inclusion in the lab.

The first video in the safety training series describes the importance of maintaining positive safety culture, which includes people’s perceptions and attitudes toward safety. This video, along with the other five, is on our NIGMS laboratory safety training and guidelines webpage.

“There aren’t many professions that can provide this much opportunity for learning, especially when it comes to understanding how our bodies work. I really love what I do—I wouldn’t trade it for anything,” says Alan Saghatelian, Ph.D., a professor in the Clayton Foundation Laboratories for Peptide Biology at the Salk Institute for Biological Studies in La Jolla, California. From studying new facts and experimental techniques to adopting new ways of thinking, researchers never stop learning, and Dr. Saghatelian credits his love for learning and exploring as reasons why he’s perfectly suited for science. He’s used these passions to build a successful career in biochemistry.

From Chemistry to Biology

Dr. Saghatelian’s love for chemistry began when he was young. He was drawn to how predictable it could be: Mix two chemical compounds in the same way and they’ll always combine to form the same substance, as dictated by the rules of chemistry.

Why Do Cells Die?

You might know that tiny individual units called cells make up your body. But did you know some of your cells die every day as a part of their normal life cycle? These deaths are balanced by other cells splitting into two identical cells, a process called mitosis.

Two purple- and orange-speckled ovals (cells). The bottom left cell shrinks and becomes several bright yellow circles. The top right cell morphs into thick, bright yellow strands that align along the center of the cell and then pull apart into two new cells.

“One of the best aspects of research is the excitement of discovery, being the first person in the world to know a small detail about the system you’re studying,” says Jeffrey Mugridge, Ph.D., an assistant professor of chemistry and biochemistry at the University of Delaware in Newark. We talked with Dr. Mugridge about how a pet store job sparked his early interest in science, why he decided to change his career trajectory after graduate school, and what he believes is key to being a successful researcher.

Q: How did you first become interested in science?

A: My strong interest in science didn’t develop until I was in high
school—I wasn’t one of those kids who had a chemistry set or a deep love for dinosaurs or anything like that. But in high school, I worked in a pet store, where I learned a lot about aquarium science, including the ins and outs of managing water chemistry to keep fish alive. I also had a fantastic chemistry teacher who really helped me foster a love for the field.

Diversity Supplement Program Paves the Way for Talented Researchers

“I hope that one day I’m able to increase our understanding of evolution, and I also hope to increase access to research. I want others to know that this space is open to people who look like me, who come from disadvantaged backgrounds, and who are underrepresented in the sciences,” says Nkrumah Grant, Ph.D., a postdoctoral research associate (postdoc) in microbiology and molecular genetics at Michigan State University (MSU) in East Lansing.

Dr. Grant’s work receives support from the NIGMS Diversity Supplement Program (DSP), which is designed to improve the recruitment and training of promising researchers from diverse backgrounds. Diversifying the scientific workforce can lead to new approaches to research questions, increased recruitment of diverse volunteers for clinical studies, an improved capacity to address health disparities, and many other benefits.

Q&A With Dylan Burnette: Muscle Cells, Cell Movement, and Microscopy

“We scientists know very little of what can be known—I find that invigorating,” says Dylan Burnette, Ph.D., an associate professor of cell and developmental biology at Vanderbilt University School of Medicine in Nashville, Tennessee. “Most people find it exhausting, but I’m comfortable with not knowing all of biology’s secrets.” In an interview, Dr. Burnette shared his lab’s work on muscle cells, the knowledge he hopes readers take away from his research, and some advice to future scientists about being comfortable being wrong.

Q: How did you first become interested in science?

A: Unlike with other subjects (it took me a long time to learn how to read), I excelled at science. In third-grade science class, I knew every answer on the tests. It didn’t occur to me at the time, but I did well because I found it interesting. I decided I wanted to become a medical doctor that year. Back then, doctors were the only type of person who I thought did any type of science.

Bridging the Representation Gap in Biomedical Research

“We hope that students come out of our program feeling like they’re part of a community. Many of us feel inadequate or struggle in some way during graduate school—it can be a challenging time. I want to build a community that our students can always come back to for support,” says Elana Ehrlich, Ph.D., the co-director of the Bridges to the Doctorate Research Training Program (B2D) at Towson University (TU), in Towson, Maryland, alongside Michelle Snyder, Ph.D..

The TU B2D is one of several NIGMS-supported B2Ds, which are dedicated to developing a diverse pool of well-trained biomedical scientists who will transition from master’s degree programs to research-based doctoral degree programs. B2Ds partner with Ph.D.-granting institutions to help aid students in the master’s-to-Ph.D. transition. Students in all B2Ds earn a thesis-based master’s degree and receive training to design, conduct, and analyze experiments effectively. At the same time, these students learn how to build successful applications for doctoral programs, whether they apply to the B2D’s partner school or another Ph.D. program.

While she was in graduate school, Mandy Muller, Ph.D., became intrigued with viruses that are oncogenic, meaning they can cause cancer. At the time, she was researching human papillomaviruses (HPVs), which can lead to cervical and throat cancer, among other types. Now, as an assistant professor of microbiology at the University of Massachusetts (UMass) Amherst, Dr. Muller studies Kaposi sarcoma-associated herpesvirus (KSHV), which causes the rare AIDS-associated cancer Kaposi sarcoma.

A Continental Change

Dr. Muller has come a long way, both geographically and professionally, since her childhood in France. She was the first person in her family to graduate from high school, where she excelled in science, and went on to attend École Normale Supérieure (ENS) de Lyon, a research-oriented undergraduate institution in Lyon, France. “We spent weeks at a time in laboratory-based classes, working in real labs. That’s when I realized people could do research full-time, which caught my attention,” says Dr. Muller. She double-majored in biology and geology, and soon chose to focus her career on immunology and virology.

If you struggle to wake up in time for school or work or feel drowsy during a trip abroad, your circadian rhythms may be out of sync with your environment. Circadian rhythms are your internal timekeepers, and almost all organisms, from bacteria to plants and animals, have them. You can’t see them, but you can feel their effects—they control when you get sleepy, when you wake up in the morning, and when you feel hungry. Among other signals, the brain uses sunlight to keep time.

“It’s so fun to try to make meaning from a confusing experimental result and talk to other scientists who are excited by the same questions you are,” says Elizabeth Wayne, Ph.D., an assistant professor of biomedical engineering and chemical engineering at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania. We talked to Dr. Wayne about her career trajectory, research on immune cells, and belief that scientists can change the world.
