Hopkins Undergraduates Design Pathfinding Research Projects

Junior Nate Dominy's study of the dieting habits of Howler monkeys in the threatened jungles of Costa Rica will go a long way toward explaining why some monkeys are on the verge of extinction and others are not.

The results of senior Percy Lee's AIDS research completed in a medical lab at The Johns Hopkins School of Medicine will be published in a medical journal later this year.

And after senior Juliette Wells pored through original letters and unpublished manuscripts of Victorian novelist Barbara Pym in an old Cambridge, England library, she developed a thesis that offers a whole new look at some of Pym's characters.

These are just a few of the undergraduates at The Johns Hopkins University who have designed and completed their own research projects, many of which lie on the cutting edge of study in medicine, the sciences, arts and humanities.

Recognized as the country's first graduate research university, one of Hopkins' attractions for many undergraduates is the opportunity to get hands-on experience working on important, graduate-level research, often along-side top researchers in their fields. The Provost's Undergraduate Awards For Research and Excellence is one way students can do that. Every year some 50 students are awarded up to $2,500 to propose and carry out their own research projects.

On March 27, from 4:30 to 6 p.m., Hopkins provost and vice president for academic affairs Steven Knapp will host the annual awards ceremony. Beginning at 3 p.m. there will be a poster session at which students will display the results of their research. All activities will take place in the Glass Pavilion of Levering Hall on the Homewood campus, 3400 N. Charles St. in Baltimore.

Following is a list of the undergraduates recognized with Provost Undergraduate Awards for Research and Excellence.

1997 Provost Undergraduate Research Awards
at The Johns Hopkins University

Creating a shape-changing robot
David Stein, (Brooklyn, N.Y.), a senior biomedical engineering and engineering mechanics major, designed small metamorphic robots that can change shape and reconfigure themselves according to the requirements of the job assigned to them. In the future, larger and stronger versions of Stein's robots might stretch themselves across a waterway to form a temporary bridge. After an earthquake, these devices might position themselves along a damaged wall to help stabilize the building. They could also play a key role in a space station, forming a universal docking bay that could connect with space ships and satellites of varying sizes and shapes.
   Stein will remain at Hopkins to obtain his master's in mechanical engineering, has been drawing on the innovative robotics theories developed by his faculty sponsor, Greg Chirikijian, an assistant professor of mechanical engineering.

In search of ... lactating female Howler monkeys
Nate Dominy (Doylestown, Pa.), a junior majoring in anthropology, spent last summer conducting research in the neo-tropical forests of Centro Ecologico La Pacifica, Costa Rica, studying the diets of lactating female Howler monkeys. The research is important in understanding why other Costa Rican monkeys, like the Spiders and Capuchins, are declining or even on the verge of extinction, while the Howlers are faring quite well. The work wasn't especially dangerous, says Dominy, but it was demanding.
   "Capturing monkeys is extremely difficult," says Dominy. "After all, they are moving in the top of the trees and are the size of a large house cat. So hitting them with the tranquilizer can be hard, especially since their rump is the only safe place to dart them."
    Then there is the danger of being bitten. Howlers have an impressive set of canines--larger than any dog--that, if they awoke from their sedatives early, would be used savagely on a human researcher, Dominy says.

Although audio "real time" on the Internet may be useful for many people, just that fraction of a second delay in sound over the net makes collaboration among symphony composers cyberly impossible. But senior Kito Mann, (Burke, Va.) a computer science major and an accomplished musician, is developing a JAVA-based "Dynamic Audio" system that will allow a composer at Peabody to compose music with a friend at Julliard over the Internet without missing a beat.

Architecture meets ecology
Matthew Schernecke (Philadelphia, Pa.)Jonathan Weinberger (Scranton, Pa.), both juniors, are among a small handful of people in recent years to be granted personal interviews with the famous and eccentric architect Paolo Soleri, who in the 1970s began building an experimental community in the Arizona high desert north of Phoenix. Weinberger and Schernecke studied the socioeconomic, political and historical ramifications of Soleri's urban planning fantasy, which he calls Arcosanti, in an attempt to identify potential solutions for large American cities. The two students also studied the historical impact of previous American "utopias" and so-called experiments, comparing them with Arcosanti. Arcosanti embodies Soleri's vision of "arcology," which combines architecture and ecology, and is intended to reduce waste and suburban sprawl by housing people in space-saving, self-sufficient complexes and preserving the environment.

How is a grasshopper like a person?
By studying molecular mechanisms in grasshoppers, Arthur Tsai, (Woodside, N.Y.), may have taken science a step closer to understanding and treating spinal cord injuries. Tsai studied the cellular and molecular cues involved in guiding genetic instructions for the development of embryos of grasshoppers. The work also has possible ramifications for studying the regeneration of axons, or nerve fibers, in attempts to repair spinal cord injuries. Tsai, who plans to attend medical school in the fall, will publish his findings in a scientific paper.

On the tip of your tongue....
Matthew Goldrick (Hockessin, Del.), a senior majoring in cognitive science, is creating a computer program that simulates how the brain's neural network selects words to go with meanings--a process that may seem trivial until a person is in a state where he or she can think of a meaning but can't find the form of its word. To design the computer program, Goldrick studies clues from speech errors made by both healthy people and those suffering neurological damage. The program simulates a theory developed by his faculty supervisor, Brenda Rapp, an assistant professor of cognitive science, that may explain the mechanisms behind errors that occur in the brains of both healthy and injured people.

A computer in the orchestra pit?
Chrysa Presta, (Annapolis, Md.) a senior at Peabody Institute combines her two passions--computer music and music composition--with her score, L'Ora Notturna. This is a composition for a live orchestra and live electronics, using real-time audio digital signal processing and conducted electronics. To evoke a nocturnal mood, Presta went out into the night and recorded the sounds of cicadas, crickets, frogs, the wind and other natural music that the night makes. She then recorded certain music instrumental effects and integrated them with her recordings of the nocturnal outdoor soundscapes, creating a rich, organic atmosphere. For example, certain piano sounds such as quick plucking on the strings, were blended with the sound of cicadas and crickets. From there, she composed a musical score which will combine 15 live instruments with the computer. During the performance, taking cues from the conductor, the "musician" at the computer will use its mouse to make the machine as expressive as any piano.

Protecting the environment
Thomas Gillard, (Alexandria, Va.) a senior majoring in civil engineering, is studying what happens when contaminated water seeps through layers of clay, creating a possible health hazard. His research may lead to better design of landfills to prevent such leaks from occurring.

Better breathing for cystic fibrosis victims
Senior Anupa Laheri's (Leonardtown, Md.) research in gastoenterolgist Sandra Guggino's lab may lead to better treatment for children suffering from cystic fibrosis. By isolating in human tissue a"dry airwave" that exacerbates cystic fibrosis, a tissue that had been previously found in rats, Laheri's work will lead to better drug treatment in the disease. Her findings will be published in a medical journal.

A new look at Barbara Pym
Senior Juliette Wells (Springfield, Va.) traveled to Cambridge, England to study original archives of early 20th century English novelist Barbara Pym, author of Excellent Women and The Sweet Dove That Died. By studying Pym's letters, notes and unpublished manuscripts, Wells has gained a different insight into what drove this little-studied English writer to pen certain characters in her published novels.

After apartheid
Matthew Nemeth (Riverside Drive, N.Y., N.Y.), a senior, traveled to South Africa to study its urban development in a post-apartheid age.

Breakthroughs in the fight against AIDS
Senior Percy Lee's (Arcadia, Calif.) study, which identifies and studies the gene, bcl-2 Homolog in Karposi's Sarcoma Virus could have important implications in the treatment of AIDS patients. His findings will be published in a medical journal.
