Pavan Ravindra, Scott Moroch, Jesse Matthews and Seungtaek Daniel Oh have been named 2020 Goldwater Scholars.

For the third year in a row, the University of Maryland’s four undergraduate nominees have been awarded scholarships by the Barry Goldwater Scholarship and Excellence in Education Foundation, which encourages students to pursue advanced study and research careers in the sciences, engineering and mathematics. 

UMD’s 2020 Goldwater Scholars, all juniors, are:

  • Jesse Matthews, a chemical engineering and mathematics dual-degree student who is also a member of the University Honors program in the Honors College;
  • Scott Moroch, a physics major;
  • Seungtaek Daniel Oh, a biological sciences major with a specialization in cell biology and genetics who is also a member of the Integrated Life Sciences program in the Honors College;
  • Pavan Ravindra, a biochemistry and computer science dual-degree student who is also a member of the Integrated Life Sciences program in the Honors College.

Over the last decade, UMD’s nominations yielded 33 scholarships—the most in the nation, followed by Stanford University with 32. Harvard University, the Massachusetts Institute of Technology and Johns Hopkins University also rank in the top 10. 

“Our scholars are a uniquely talented group, already making discoveries in their fields of study—from developing more stable batteries and innovative power supplies to streamlining the pathway of drug design and understanding the contributions of RNA in cancer and other diseases,” said Robert Infantino, associate dean of undergraduate education in the College of Computer, Mathematical, and Natural Sciences. He has led UMD’s Goldwater Scholarship nominating process since 2001.

Matthews, Moroch, Oh and Ravindra were among the 396 Barry Goldwater Scholars selected from 1,343 students nominated nationally this year. Goldwater Scholars receive one- or two-year scholarships that cover the cost of tuition, fees, books, and room and board up to $7,500 per year. These scholarships are a stepping-stone to future support for the students’ research careers. The Goldwater Foundation has honored 70 UMD winners and five honorable mentions since the program’s first award was given in 1989.

Jesse Matthews
Matthews, a Banneker/Key Scholar from Silver Spring, Maryland, is working to make safer lithium-ion batteries. Lithium-ion batteries typically contain a liquid electrolyte, through which the lithium ions move. Matthews is developing new, non-flammable solid polymer electrolytes, which would be inherently safer than liquid electrolytes for applications like implanted biomedical devices. 

Matthews co-authored a paper accepted for publication in the journal Electrochimica Acta and was selected as the top student poster presenter in a fuels, petrochemicals and energy category at the 2019 American Institute of Chemical Engineers Annual Meeting. He also received the Dinah Berman Memorial Award, which honors one junior engineering major at UMD who shows outstanding scholastic, leadership and service endeavors.

“These are remarkable accomplishments for an undergraduate and clearly demonstrate a strong work ethic,” said Peter Kofinas, chair of UMD’s Department of Chemical and Biomolecular Engineering, who has been working with Matthews. 

In the field of mathematics, Matthews worked for two summers with Radu Balan, a professor of mathematics and the Center for Scientific Computation and Mathematical Modeling, to improve noise reduction in signal processing for speech recognition and X-ray crystallography.

Last summer, he mentored four high-school students on a research project as part of the university’s ESTEEM (Engineering Science and Technology to Energize and Expand Young Minds) Summer Engineering Research-Quest for underrepresented minorities. 

After he graduates, Matthews plans to pursue a Ph.D. in chemical engineering.

Scott Moroch
Moroch, a native of Wayne, New Jersey, designed his own particle accelerator when he was still in high school. Since enrolling at Maryland, he has been working on UMD’s cyclotron with Timothy Koeth, an assistant professor in the Department of Materials Science and Engineering and the Institute for Research in Electronics and Applied Physics. 

A cyclotron is a type of particle accelerator that won its inventor the Nobel Prize in physics in 1939. The beams that cyclotrons produce, while potentially dangerous, accomplish wondrous things—killing cancer cells with extreme precision, for instance, or changing atoms into a different element altogether.

Moroch is working with Koeth to develop a novel cyclotron storage ring for Lockheed Martin. The company is interested in using the technology for a new class of power supplies for aerospace electric propulsion systems that can carry things into the solar system and beyond. 

With initial funding from Lockheed, Moroch showed that a cyclotron design could be effective, but it was unstable. So the company funded a more ambitious project at UMD where the instabilities could be factored out. Moroch now leads a significant portion of the research team. 

“In the past 20 years, I have mentored several dozen undergraduate researchers, and Scott Moroch is the first that has demonstrated the entire cycle of research and brought in substantial research funds,” Koeth said.

Moroch also helped design an electron beamline in collaboration with Los Alamos National Laboratory. He plans to pursue a Ph.D. in accelerator physics.

Seungtaek Daniel Oh
Oh, who emigrated from South Korea before first grade and went to high school in Germantown, Maryland, has conducted RNA research in laboratories at the National Institutes of Health (NIH) and UMD. 

At the NIH’s National Cancer Institute (NCI), Oh analyzed non-coding and coding RNA and protein expression to identify potential pathways that would explain how a natural compound called butylcycloheptyl prodiginine blocks the proliferation of cells. This work resulted in a co-authored paper published in 2019 in the journal Cell Chemical Biology. 

“Seungtaek’s ability to comprehend complex scientific concepts and experimental techniques both in lab practices and in literature research surpasses others I have trained,” said Barry O’Keefe, chief of the NCI’s Molecular Targets Program. “He is eager to learn, curious, creative, thorough and thoughtful, and he shows sincere passion for scientific research.”

In a different NCI laboratory, Oh worked with Joseph Ziegelbauer to investigate circular RNAs, a class of non-coding RNA that have been linked to a variety of disorders including cancer, diabetes and Alzheimer’s disease. 

Back on UMD’s campus, Oh is studying RNA dynamics and structure in a hepatitis B viral system using nuclear magnetic resonance spectroscopy. This research—performed with Kwaku Dayie, an associate professor in the Department of Chemistry and Biochemistry—aims to improve our understanding of RNA’s biological functions and molecular interactions with potential drug therapies.

Oh was awarded the university’s Presidential Scholarship; the Maud, Walter, and Grace McCormack Scholarship; and a Global Fellows citation. He also serves as a member of the university’s Student Honor Council. He plans to pursue a Ph.D. in cancer biology.

Pavan Ravindra
Ravindra, a Banneker/Key Scholar from Clarksville, Maryland, developed an algorithm he named AMINO, for Automatic Mutual Information Noise Omission. The algorithm describes proteins and chemical systems using a minimal set of parameters—a difficult task that is usually done manually. 

The AMINO algorithm code is open source and is already being used by other research groups and pharmaceutical companies to help improve their modeling and workflow of drug design. AMINO led to a first-author scientific paper for Ravindra, which was published in the journal Molecular Systems Design & Engineering in 2019.

“Along with graduate students in my lab, Pavan continues to apply AMINO to different ambitious and relevant problems, such as how molecules fundamental to life—proteins, DNA and RNA—adopt different shapes and forms,” said Pratyush Tiwary, an assistant professor in the Department of Chemistry and Biochemistry and the Institute for Physical Science and Technology. “Predicting this flexibility is often the key to designing effective, nontoxic drugs for different diseases. Pavan’s method is helping make it possible to predict this flexibility in an inexpensive, effective and insightful manner.”

Ravindra also worked at the NIH’s National Institute of Neurological Disorders and Stroke with Jeffrey Smith (B.S. ’73, zoology). There, he developed a computational model of neurons in the pre-Bötzinger complex, an area responsible for regulating intrinsic breathing patterns in humans. 

Outside the lab, Ravindra is president of UMD’s Rubik’s Cube Club. He currently ranks 102nd in the world for solving a Rubik's cube and 24th in the world for solving it one-handed. After graduation, he plans to pursue a Ph.D. in chemical physics with a focus on computational chemistry.
