Historically, crowdsourcing has played an important role in certain fields of scientific research. Wildlife biologists often rely on members of the public to monitor animal populations. Using backyard telescopes, amateur astronomers provide images and measurements that lead to important discoveries about the universe. And many meteorologists use data collected by citizen scientists to study weather conditions and patterns.
Now, thanks largely to advances in computing, researchers in computational biology and data science are harnessing the power of the masses and making discoveries that provide valuable insights into human health.

The blood-brain barrier—the ultra-tight seal in the walls of the brain’s capillaries—is an important part of the body’s defense system. It keeps invaders and other toxins from entering the human brain by screening out dangerous molecules. But the intricate workings of this extremely effective barrier also make it challenging to design therapeutics that would help us. And as it turns out, getting a drug across the blood-brain barrier is only half the battle. Once it’s across, the drug needs to effectively target the right cells in the brain tissue. With this in mind, it’s no surprise that challenges this complex are solved through collaboration among scientists from several different specialties.
Elizabeth Nance , an assistant professor of chemical engineering at the University of Washington in Seattle and a recent recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE), focuses her research on understanding the barriers in the brain and other cell- and tissue-based barriers in the body to see how nanoparticles interact with them. Her lab uses nanoparticles to package therapies that will treat newborn brain injury, which can occur when the brain loses oxygen and blood flow, often during or immediately prior to delivery. This damage can lead to cerebral palsy, developmental delays, or sometimes death. Early interventions for newborn brain injury can be valuable, but they need to target specific, injured cells without harming healthy ones.

A college degree was far from the minds of Joshua and Caleb Marceau growing up on a small farm on the Flathead Indian Reservation in rural northwestern Montana. Their world centered on powwows, tending cattle and chicken, fishing in streams, and working the 20-acre ranch their parents own. Despite their innate love of learning and science, the idea of applying to and paying for college seemed out of reach. Then, opportunities provided through NIGMS, mentors, and scholarships led them from a local tribal college to advanced degrees in biomedical science. Today, both Joshua and Caleb are Ph.D.-level scientists working to improve public health through the study of viruses.
Joshua Discovers Unexpected Opportunities

As the oldest of four brothers, Joshua was the trailblazer in the family. But like most trailblazers, his path to a scientific career wasn’t always smooth. He attended a reservation school until sixth grade, then was homeschooled. He earned his GED through the local tribal community college, Salish Kootenai College (SKC) in Pablo, so he could begin to take college-level chemistry.

Finding a career path in
biomedical research can be challenging for many young people, especially when
they have no footsteps to follow. We asked three recent college graduates who
are pursuing advanced degrees in biomedical sciences to give us their best
advice for undergrads.
Tip 1: Talk with mentors and peers, and explore opportunities.
One of the most challenging things for incoming undergraduates is simply to find out about biomedical research opportunities. By talking to professors and peers, students can find ways to explore and develop their interests in biomedical research.

Mariajose Franco, a first-generation college student, recently graduated with honors and dual degrees in molecular and cellular biology and physiology from the University of Arizona in Tucson. She’s now in a postbaccalaureate program at the National Cancer Institute and has her eye on combined M.D.-Ph.D. programs.
As an undergraduate, a course in cancer biology piqued her interest, and she reached out to her professor, Justina McEvoy, to see if she could join her lab. As a sophomore, Franco began working on rhabdomyosarcoma, a rare childhood cancer that arises from cells that normally develop into skeletal muscle. Through the NIGMS Maximizing Access to Research Careers (MARC) program, she received support to conduct two research projects during her junior and senior years. In addition to offering research opportunities, the MARC program was instrumental in providing training in scientific writing and conference poster presentations, and navigating applications, Franco says.

Brain injuries, cancer, infections, and wound healing are some of the complex and pressing
health concerns we face today. Understanding the basic science behind these diseases and biological processes is the key to developing new treatments and improving patient outcomes. Physician scientists—medical doctors who also conduct laboratory research—are essential to turning knowledge gained in the lab into innovative treatments, surgical advances, and new diagnostic tools.
In this blog, we highlight the work and impact of three surgeon scientists funded by NIGMS at different stages in their careers: Dr. Nicole Gibran (current grantee), Dr. Rebecca Minter (former grantee), and Dr. Carrie Sims (former grantee). Their work, despite the historical underrepresentation of women in the physician scientist training community, has led to revolutionary surgical treatments, new therapeutics, better screening, and improved quality of life for patients.

Ten years ago, Chris McCulloh planned to enter medical school and fulfill his dream of becoming a surgeon. Instead, just months before he was to start med school, he ended up a patient. A freak accident—slipping on a hardwood floor, flying backwards, and landing neck-first on the edge of a glass coffee table—left him with both legs paralyzed at age 28. Undaunted, he deferred entering medical school for a year, undergoing surgery and spending months in rehab.

McCulloh has since finished medical school and recently completed a 2-year pediatric surgery research fellowship at Nationwide Children’s Hospital in Columbus, Ohio. He is now two-thirds of the way through his surgical residency at the Morristown (New Jersey) Medical Center, thanks to the assistance of a specialized wheelchair that allows him to stand nearly to his 6-foot-3 height and helps him perform five to six surgeries a day.
He’s received plenty of attention for being a surgeon with a disability. Along with several print media stories, he was interviewed in 2013 for CBS’ “The Doctors,” and in 2017, ABC’s “20/20” included McCulloh in an episode on physicians with disabilities. But it’s not the wheelchair that distinguishes McCulloh, says Gail Besner, a pediatric surgeon and researcher who hired McCulloh as a postdoctoral fellow. Rather, it’s his enthusiasm, natural research skills, and exceptional surgical prowess that make him special. Besner sees no reason why he won’t reach his goal of landing a highly competitive pediatric surgical residency. “I think he’s capable of doing anything he puts his mind to,” she says.

Six NIGMS grantees are among this year’s winners of the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring (PAESMEM). The award was established by the White House in 1995. This year, it went to 27 individuals and 14 organizations.
PAESMEM recipients were honored during a 3-day event in Washington, D.C. The event featured a gala presentation ceremony and a White House tour. In addition, each winner received a $10,000 grant from the National Science Foundation, which manages PAESMEM on behalf of the White House Office of Science and Technology Policy.
The event also included the first-ever White House State-Federal STEM Education Summit. During the summit, awardees joined leaders in education and workforce development from across the nation, including U.S. territories and several Native American tribes, to discuss trends and future priorities in STEM education. The discussions will inform the development of the next Federal STEM Education 5-Year Strategic Plan, which must be updated every 5 years according to the America COMPETES Reauthorization Act of 2010.
The six NIGMS-supported PAESMEM winners are listed below. In this blog, we will highlight the work of each one, starting with Ann L. Chester and John A. Pollock.
