THE NEW WORLD-CLASS BAYLOR SCIENCES BUILDING WILL HOST A FULL COMPLEMENT > OF NATURAL SCIENCE TEACHING, RESEARCH AND EXPERIMENTATION ON CAMPUS. THE $103 MILLION, 500,000 SQUARE-FOOT FACILITY WILL BE COMPLETED BY FALL 2004.
INCREASING RESEARCH CAPABILITIES Two significant granting organizations, the state-operated Telecommunications Infrastructure Fund (TIF) and the National Science Foundation (NSF), have provided funding to upgrade campus computer and networking capabilities. TIF awarded four grants to Baylor totaling more than $2 million, which dramatically impacted campus communications in the past year. A prestigious National Science Foundation grant received in January 2003 for $175,000 advanced leading-edge network capability on campus. The TIF grants allowed campus upgrades of library computer services, expansion of instructional offerings, improvement of networking services and enhanced access to online information resources. The addition of a wireless computer networking system now provides wireless laptop access to the Internet in every academic and residential building on campus. The NSF funds support Internet2 capability. Internet2 is a private consortium of more than 200 U.S. universities — including Baylor — that works with government and industry to develop innovative network capability on campuses. The group also provides the newest technological advances applicable to the Internet for the national research community and broader Internet use. The NSF supports Internet2 goals to ensure the Internet of the future develops into a reliable and secure medium for information sharing and to foster partnerships among academia, industry and government.

Soft robots are flexible, “or have so many joints they seem flexible,” Gravagne says; and they can be activated by small motors, fiber composites, shape memory alloys and gel polymer muscles. This idea is inspired by elephant trunks, octopus tentacles and caterpillars, he adds. A current project of Gravagne’s involves designing a soft robot with the capability to detect land mines. Since arriving at Baylor, Gravagne and John Davis in mathematics have begun collaboration, along with doctoral student Jeff Dachuna, “to see what applicability time-scale calculus has to various engineering problems where discrete and continuous phenomena coexist,” Gravagne says. “It is a cutting-edge interdisciplinary exploration of exactly the type that I think Baylor is trying to foster.” A primary research interest of Gravagne’s is “soft robots,” a significant advance beyond the stiff, heavy machines most people imagine when they think of a robot.

“Generically, physicists need mathematics to formulate questions and also to answer questions.” > Klaus Kirsten , associate professor of mathematics, received his bachelor’s, master’s and doctoral degrees from the University of Kaiserslautern, Germany. His doctoral work is in theoretical physics, specializing in quantum field theory, string theory and spectral theory. “Generically, physicists need mathematics to formulate questions and also to answer questions. If the needed mathematics is not available, (some) physicists turn into mathematicians and develop whatever is necessary to progress in answering ‘their’ questions. This is what happened and continues to happen to me,” Kirsten says. “The methods I have developed raised the interest of mathematicians because their approach and my approach were complementary. I had a physicist’s education and so simply had a different viewpoint, which sometimes is very fruitful. Kirsten taught as a visiting professor at the University of Trento in Italy, then went on to serve as an Alexander von Humboldt Fellow at the University of Barcelona in Spain, after which he conducted research at the University of Leipzig in Germany and at the University of Manchester in England. He also received visiting appointments at the University of La Plata in Argentina and the University of Naples in Italy. Since 2001, Kirsten has been a postdoctoral associate at the Max Planck Institute for Mathematics in the Sciences in Leipzig, Germany. With two books to his credit, Spectral Functions in Mathematics and Physics and the forthcoming Spectral Geometry of Physics , Kirsten also has written 80 peer-reviewed articles and is involved in six current research projects.
> Melanie McEwen , associate professor of nursing, received her bachelor’s degree at the University of Texas at Austin, her master’s from Louisiana State University Medical Center at New Orleans and her doctorate from Texas Woman’s University in 1990. McEwen has written several nursing textbooks including Community-Based Nursing and an instructor’s manual for the text. She is co-editor of Theoretical Basis for Nursing, in addition to writing 10 chapters of the book and co-edited the 3rd edition of Community Health Nursing: Promoting the Health of Populations . She also has written numerous articles for reviewed journals and is seeking funding to develop a master’s of nursing education track. She also assisted nursing professor Frances Strodtbeck in writing a $1 million grant for development of a case management program for children with developmental problems. McEwen considers nursing her calling. “As a child I always wanted to take care of kids with cuts and scrapes and injured animals. For as long as I can remember, I wanted to be a nurse. It’s where my interests and my gifts are,” she says. McEwen’s research interests include pediatric immunization policy and asthma, and other health issues for school children. For her next research topic, she would like to look at the disparity of diagnoses of attention deficit-hyperactive disorder (ADHD) between economically disadvantaged and other children. The disorder is diagnosed more frequently among children from higher socio-economic groups, and McEwen suspects disadvantaged ADHD children have been overlooked in diagnosis and treatment.

> DeAnna Toten Beard , assistant professor of theater arts, received her bachelor’s degree from Mary Washington College, a master’s from the State University of New York, and her doctorate from Indiana University, Bloomington in 2001. She came to Baylor from the University of North Carolina, Wilmington, where she served as a visiting professor of theater history. Toten Beard wanted to be able to write in both artistic and research venues, so she decided to do doctoral work in theater history after receiving her master of fine arts degree. She specializes in dramaturgy — the study of how a play script works — which qualifies her to collaborate in production with directors and playwrights on genres of literature, history of certain kin ds of plays, and dramatic structure. She has published in On-Stage Studies , a theater journal, and has written a book chapter for the upcoming Blackwell’s Guide to Modern American Drama , among other publications.Toten Beard’s research focus is early 20th century drama and theatrical modernism, particularly American Expressionism. “My next research topic will be the experimental plays of Theodore Dreiser,” a writer known for his novels more than his plays, she says. Baylor theatergoers should look for next fall’s adaptati on of Marlowe’s Doctor Faustus, a project Toten Beard is working on with Steven Pounders in the theater department. “My next research topic will be the experimental plays of Theodore Dreiser.”

Tsang’s research interests include moral rationalization and moral religion naturally motivation, forgiveness, gratitude, and the psychology of religion. She was awarded the Howard Baumgartel Peace and Justice Award for Thesis/Dissertation Research at the University of Kansas. The dissertation leads to the study studied changes in moral emotions by having subjects read an essay about of morality.” people who suffer from hunger in other parts of the world, then looking to see if the essay influenced moral emotions and moral behavior. “Since I’m a social psychologist, I was interested in studying religion, and religion naturally leads to the study of morality,” Tsang says. She is working on a project that looks at gratitude, observing behavioral reactions of the subjects when someone does them a favor. She also is engaged in a collaborative project with a colleague at Southern Methodist University studying gratitude in school-age children.

The Astrophysics and Space Science Theory Group conducts research in a variety of areas and includes graduate and undergraduate students along with Baylor professors and research scientists. One of the most exciting concepts under investigation, Hyde said, involves complex dusty plasmas, a relatively new topic discovered in 1994 at the Max Planck Institute for Extraterrestrial Physics. “That’s when things began to happen,” Hyde said. A complex dusty plasma is a completely new state of matter that can change from solid to liquid to gas. Researchers have learned that such plasmas can also contain particles — dubbed dust — that were once thought to be contaminants but can actually become embedded within the plasma itself. Researchers are excited because the resulting complex plasma, which is easy to control, allows them to study interesting phenomena such as phase changes. “Dusty plasma research is more widespread now, but Baylor has been at the forefront of it all,” Hyde said. “It’s pure physics that brings a confluence of types of research into play.” Semiconductor people are enthusiastic because a method for decreasing the contaminants created by the plasma etch process can be built into the chip, reducing or even eliminating contamination, improving chip production, and cutting costs. Industries ranging from space exploration to communication to commerce could also benefit from findings, which may lead to the next generation of semiconductor chips. Through the Early Universe Cosmology and Strings Group (EUCOS), Baylor also leads the way in string theory research, one of the most exciting and fast-paced research topics in physics today.

B Y M A Enginee from nothing into a research, education, and outreach paradigm unlike any other in the country. A partnership between Baylor University and Texas State Technical College/Waco, CASPER includes two theoretical research groups at Baylor, an experimental lab at TSTC and an intensive educational outreach program that brings students and educators onto both campuses as well as develops curricula for public school science courses. A Baylor physics professor since 1988, Hyde had been doing theoretical physics research for years but lacked an experimental facility. He knew that neighboring Texas State Technical College/Waco offered cutting-edge technical programs, whose teachers had experience in Los Alamos, Livermore, and other leading scientific labs. “I thought there had to be a way to meld what Baylor had with what TSTC had,” Hyde said. The opportunity presented itself when TSTC opened a new automotive lab, vacating a 5,000-square-foot facility. Hyde saw it as an ideal location for an experimental lab that could be supported by the TSTC’s technical programs and began working toward a partnership between the two institutions. “Once we forged a deal between Baylor and TSTC, everything just fell together,” Hyde said. “We really hit a cosmic wave of interest and research and were able to get funding that allowed us to hire some outstanding people.” About $250,000 went into renovations at the TSTC lab, where air conditioning, fiber optics, a DC power supply from the Super Colider and other features were added. The facility now houses CASPER’s Hypervelocity Impacts and Dusty Plasmas Lab and the Space Science Lab, where researchers create laboratory simulations of dusty plasmas, develop prototype designs of dust particle accelerators, and provide real-world support for the theoretical research groups. One of TSTC’s faculty members works full time at the experimental lab, with technical support provided by TSTC technical students and graduates. “Baylor is the only university in the world I know of that has this type of environment,” Hyde said. “It gives great mentorship and internship opportunities for both TSTC and Baylor students.” “Our research covers from the beginning of time to the latest space and theoretical plasma information,” Hyde said. CASPER’s two theoretical groups, located on the Baylor campus, are involved in dozens of research projects covering a range of issues. Among them are dusty plasmas and super strings—two breaking topics on the horizon.

the TSTC campus, introduces students from the Waco area to physics in a theatre-like atmosphere that’s “purely wild science,” Hyde said. But it is the interdisciplinary approach that brings together math, technology, physics, and other disciplines into a team setting that Hyde finds most enjoyable. “One of most unique things about CASPER is that we always have students of all levels involved in every part of every activity, at every level,” Hyde said. Undergraduate, graduate, and sometimes post-doctorate students work alongside senior research scientists, teachers, technicians, and sometimes high school students in classrooms, seminars, and even research labs. Allowing that kind of access to labs is something unique among research universities. “Very few universities are bringing students into the labs,” he said, “and Baylor is doing it most successfully. We think it’s an important part of giving our students the opportunity for a well-rounded education and opportunities they wouldn’t otherwise get.” “At CASPER, we have a full pipeline path that can take students as young as kindergarten and as far along as post-doctoral fellows,” Hyde said, “and keep them involved in real research, real learning in a team environment. Our emphasis is on the students and what’s good for them.” If you would like to see a 30-second commercial about this research, please visit: http://www.baylor.edu/research/
