“I never thought I could make an impact on chemistry and students’ lives. But now, I’m the head of a lab with several Ph.D. and undergraduate students and a postdoctoral researcher; and we’re developing simple, low-cost lab techniques that can be adopted by labs across the world,” says Abraham Badu-Tawiah, Ph.D., the Robert K. Fox Professor of Chemistry at Ohio State University in Columbus. We talked with Dr. Badu-Tawiah about his career progression, research, and advice for students hoping to launch a career in science.

Q: How did you get started on the path to a career in science?

A: In Ghana, where I grew up, education works differently than in the United States. High school students are assigned subjects to study primarily based on their grades, and once assigned a subject, it’s difficult to switch. I was assigned to math, physics, and chemistry, which put me on a path toward being an engineer. I was happy to be studying science, but after the death of my brother, I wanted to study medicine more than engineering.

What Does an Immunologist Do?

This post is part of a miniseries on the immune system. Be sure to check out the other posts in this series that you may have missed.

Immunology is the study of the immune system, including all the cells, tissues, and organs that work together to protect you from germs. A person who studies immunology is called an immunologist, and there are three types:

  • Researchers, who study the immune system in the laboratory to understand how it works or how it can go awry and find new treatments for immune system-related diseases
  • Doctors, who diagnose and care for patients with diseases related to the immune system, such as food allergies or immunodeficiency
  • Physician-scientists, who are both researchers and doctors and divide their time between the clinic and the laboratory

Andrew G. Campbell, Ph.D., a professor of medical science at Brown University in Providence, Rhode Island, and previous dean of the graduate school, is passionate about researching understudied diseases and helping students reach their full potential.

Dr. Campbell’s lab has studied the single-cell organism Trypanosoma brucei (T. brucei), a parasite transmitted through the bite of the tsetse fly, which is only found in specific regions of Africa. In humans, T. brucei causes African Trypanosomiasis, also known as sleeping sickness. Symptoms of this illness include headache, weakness, tiredness, and altered sleep schedules; and if left untreated, it can be fatal. Dr. Campbell studies the function of certain enzymes found in T. brucei and other infectious agents, like hepatitis B virus and HIV, with the hope that they can serve as targets for new treatments for diseases.

Two NIGMS-funded programs are teaming up to shape the future of science and technology in West Virginia (WV). One engages high school students in science, technology, engineering, math, and medicine (STEM+M); introduces them to research; and provides direct access to college through tuition waivers. In the other program, undergraduate students are paired with a researcher at their institution for a paid internship—an important step toward a career in science.

The Health Sciences & Technology Academy

“We liken our students to rosebuds. As they grow, you see them blossom into self-confident leaders,” says Catherine Morton, Ed.D., director of the Health Sciences & Technology Academy (HSTA) in West Virginia. This mentoring program is supported in part by an NIGMS Science Education Partnership Award (SEPA).

What Do Fats Do in the Body?

It’s common knowledge that too much cholesterol and other fats can lead to disease and that a healthy diet involves watching how much fatty food we eat. However, our bodies need a certain amount of fat to function—and we can’t make it from scratch.

Triglycerides, cholesterol, and other essential fatty acids—the fats our bodies can’t make on their own—store energy, insulate us, and protect our vital organs. They act as messengers, helping proteins do their jobs. They also start chemical reactions that help control growth, immune function, reproduction, and other aspects of basic metabolism. Fats also help the body stockpile certain nutrients. Vitamins A, D, E, and K, for example, are stored in the liver and in fatty tissues.

The cycle of making, breaking, storing, and using fats is at the core of how all animals, including humans, regulate their energy. An imbalance in any step can result in disease. For instance, having too many triglycerides in our bloodstream raises our risk of clogged arteries, which can lead to heart attack and stroke.

Research Organism Superheroes: Fruit Flies

Those pesky little bugs flying around the overripe bananas in your kitchen may hold the key to understanding something new about how our bodies work. That’s right, the fruit fly (Drosophila melanogaster) is a widely used research organism in genetics because of its superpower of reproducing quickly with similar genes to people.

Researchers have been studying fruit flies for over a century for many reasons. First, they’re easy to please—just keep them at room temperature and feed them corn meal, sugar, and yeast (or those bananas on your counter!). Second, they reproduce more quickly and have shorter life cycles than larger organisms. A female can lay up to a hundred eggs in a day, and those eggs develop into mature adult flies within 10 to 12 days. A third reason is the simplicity of the fruit fly’s genome, which only has four pairs of chromosomes compared to the 23 in humans. And on a logistical note, the male and female flies are easy to tell apart (genetic studies often require separating males and females, which isn’t an easy feat in all organisms).

“Science is for everyone. It’s in everything. It exists in cultures everywhere,” says Chantel Tsosie, a master’s student in the NIGMS-supported Research Initiative for Scientific Enhancement (RISE) program at Northern Arizona University (NAU) in Flagstaff. The program aims to prepare a diverse group of students for research careers through culturally relevant support, hands-on research experiences, and a tailored curriculum.

Chantel started her bachelor’s studies at NAU as a dental hygiene major and later changed her focus to biomedical sciences. “I’m from the Navajo Nation, and growing up on the reservation, I wasn’t really exposed to research as a career. At NAU, I began taking classes like microbiology and chemistry and found that I loved the lab portions of those. I met scientists who were Indigenous and really started looking up to them,” she says. When a faculty member brought RISE to her attention, she was immediately interested and reached out to its leaders, Catherine Propper, Ph.D., and Anita Antoninka, Ph.D.

“Many of the students we work with don’t have access to a laboratory through their local schools. For them, CityLab is their first exposure to a laboratory environment—these are hugely important moments for these kids,” says Carl Franzblau, Ph.D., the founder of CityLab at Boston University (BU). CityLab was established more than 30 years ago as a science education outreach program for precollege students and teachers through a partnership between the Chobanian & Avedisian School of Medicine and the Wheelock College of Education & Human Development at BU.

“Since our first Science Education Partnership Award (SEPA) grant in 1991, our mission has been to inspire students to consider careers in the biomedical sciences and broaden the opportunities that are available to them,” says Carla Romney, D.Sc., the director of research for CityLab. Continuous SEPA funding since 1991 has allowed CityLab to fulfill its mission and provide students with state-of-the-art biotechnology laboratory facilities and curricula.
