She is among the 417 students named 2022 Goldwater Scholars from the 1,242 students nominated by 433 academic institutions in the United States, according to the Barry Goldwater Scholarship & Excellence in Education Foundation. Each scholarship provides as much as $7,500 each year for as many as two years of undergraduate study.

Penn has produced 23 Goldwater Scholars in the past seven years and a total of 55 since Congress established the scholarship in 1986.

Laila Barakat Norford is majoring in bioengineering with minors in computer science and bioethics in Penn Engineering. As a Rachleff Scholar, Norford has been engaged in systems biology research since her first year. Her current research uses machine learning to predict cell types in intestinal organoids from live-cell images, enabling the mechanisms of development and disease to be characterized in detail. At Penn, she is an Orientation Peer Advisor, a volunteer with Advancing Women in Engineering and the Penn Society of Women Engineers, and a teaching assistant for introductory computer science. She is secretary of the Penn Band, plays the clarinet, and is a member of the Band’s Fanfare Honor Society for service and leadership. Norford registers voters with Penn Leads the Vote and canvasses for state government candidates. She is also involved in Penn’s LGBTQ+ community as a member of PennAces. Norford plans to pursue a Ph.D. in computational biology, aspiring to build computational tools to address understudied diseases and health disparities.

The students applied for the Goldwater Scholarship with assistance from Penn’s Center for Undergraduate Research and Fellowships.

Kariyawasam is a double major in Engineering’s Department of Bioengineering, with concentrations in computational medicine and medical devices, and in the Wharton School, with concentrations in finance and entrepreneurship and innovation.

“We are so proud of our newest Penn Rhodes Scholars who have been chosen for this tremendous honor and opportunity,” said President Amy Gutmann. “The work Raveen has done in health care innovation and accessibility and Nicholas has done to support student well-being while at Penn is impressive, and pursuing a graduate degree at Oxford will build upon that foundation. We look forward to seeing how they make an impact in the future.”

The Rhodes is highly competitive and one of the most prestigious scholarships in the world. The scholarships provide all expenses for as long as four years of study at Oxford University in England.

According to the Rhodes Trust, about 100 Rhodes Scholars will be selected worldwide this year, chosen from more than 60 countries. Several have attended American colleges and universities but are not U.S. citizens and have applied through their home country, including Kariyawasam in Sri Lanka.

With an interest in health care innovation and accessibility, Kariyawasam is involved in several research projects, including his Wharton honors thesis that focuses on optimizing a low-cost electronic medical record system in Sri Lanka and the Philippines. He has received several research grants, including the Vagelos Undergraduate Research Grant, the Berkman Opportunity Fund grant, and the National Science Foundation’s Innovation Corps grant. At Penn, he is editor-in-chief of Synapse, a student-run health care magazine and is vice president of the Phi Sigma Biological Honor Society. He is a disc jockey for the student-run radio station, WQHS, and an executive board member of the Wharton Undergraduate Healthcare Club. He also is a former student ambassador at the Penn Health-Tech Center for Health Devices and Technology. At Oxford, Kariyawasam plans to pursue a D.Phil. degree.

Interact, Adapt, Repeat

Sophomores Linda Wu and Nova Meng spent the summer studying coevolution among plants, mutualistic bacteria, and parasitic nematodes in Corlett Wood’s biology lab.

Coevolution is all around us. Think of the elongated blooms that perfectly accommodate a hummingbird’s slender mouth parts. But not all examples of species influencing one another’s evolutionary course accrue benefits to all parties. Tradeoffs are part of the game.

This summer, sophomores Linda Wu of Annandale, Virginia, and Nova Meng of Akron, Ohio, researched an coevolutionary scenario with benefits as well as costs for the species involved. Their work, supported by the Penn Undergraduate Research Mentoring Program (PURM) and conducted in the lab of biology professor Corlett Wood, has examined the relationship among plants in the genus Medicago, beneficial bacteria that dwell in their roots, and parasitic nematodes that try to steal the plants’ nutrients.

The Center for Undergraduate Research & Fellowships provides students in the PURM program awards of $4,500 during the 10-week summer research internship. Wu and Meng stayed busy through those weeks. Whether evaluating plants in a soybean field in Michigan or tending to hundreds—even thousands—of plants in the greenhouse at Penn, these aspiring researchers built a foundation for future scientific endeavors with hands-on practice.

“It’s been an amazing experience,” says Wu. “I’ve always been interested in genetics and evolution and have found parasitic relationships in particular really interesting. I like reading about weird parasites. This summer I’ve gotten to participate in lab meetings, read books about coevolution, and expand my knowledge about the topic.”

Mentored by Ph.D. student McCall Calvert, Wu spent the summer focused on the parasites in the Medicago model system the Wood lab uses. “I’m trying to see if those nematodes are specialists or generalists, if they’re locally adapted to their host plant or open to parasitizing on different species,” Wu says.

To do so, she’s grown pots and pots of plants in the Penn greenhouse, experimentally infecting Medicago plants as well as other species, such as carrot and daisy plants, with nematodes, to measure the degree to which the parasites flourish.

Meng, who is pursuing a bioengineering major, is examining how bacteria that dwell in plant roots affect the plants’ susceptibility to parasites.

Meng’s project looked at the bacterial side of the coevolutionary relationship. Overseen by lab manager and technician Eunnuri Yi, Meng looked at four strains of bacteria, known as rhizobia. Two strains are nitrogen-fixing, giving their associated plants a crucial nutrient to promote growth, while the other two do not seem to contribute nitrogen to the plants, and instead exist as parasites in the plants’ roots. “I’m looking at what happens when we infect the plants with nematode parasites,” Meng says, “to see if the plants that are open to mutualistic rhizobia are more susceptible to the nematode parasites.”

Linda Wu is a sophomore pursuing an uncoordinated dual degree in business, energy, environment, and sustainability in the Wharton School and in biology with a concentration in ecology and evolution in the College of Arts and Sciences at the University of Pennsylvania.

Nova Meng is a sophomore majoring in bioengineering in the School of Engineering and Applied Science at Penn.
