Acoustician and Inventor
Johns Hopkins University
Jim West was born in 1931 in Prince Edward County, Virginia, and studied physics at Temple University, much to the displeasure of his parents, who wanted him to become a doctor. “My father introduced me to three black men who had earned doctorates in chemistry and physics,” says West. “The best jobs they could find were at the post office. My father said I was taking the long road toward working at the post office.”
Specializing in microphones, West went on to author 200 patents. In 1962, with Gerhard Sessler, West developed the foil electret microphone. Recently, after a distinguished 40-year career, including stints at Lucent Technologies and as a Bell Laboratories Fellow, West moved to Johns Hopkins University where he is a research professor in the Department of Electrical and Computer Engineering. West also founded the Association of Black Laboratory Employees.

Giant Panda Curator
Lisa Stevens became a familiar face (and voice) in 2005 when panda cub Tai Shan was born at the National Zoo in Washington, DC. As manager of the giant panda program for the past 20 years, she often spoke to the public and to media about how the little ball of furry cuteness was faring. Before joining the zoo’s staff, she held positions as a field research assistant, in pet and aquarium retail, veterinary clinic operations, insect zoo husbandry and interpretation, and riding stable management (she’s an avid rider and horse owner). She has a bachelor’s degree in zoology and pre-veterinary medicine from Michigan State University and attended the AZA School for Professional Management Development for Zoo and Aquarium Personnel.

William M. Jackson
University of California at Davis
William Jackson is a Distinguished Research Professor in the Chemistry Department of University of California, Davis. He has spent more than 40 years studying the chemistry of comets. He developed the use of tunable dye lasers to probe the fragments produced when light is absorbed by molecules in the laboratory. Many of these molecules that he has studied are thought to produce the same fragments in comets and in the ozone layer of the stratosphere. He led the international research team that was the first to use the telescope in the IUE (International Ultraviolet Explorer) satellite to observe comets. He still continues to study comets both in his laboratory and through various observations of them with national telescopes.
Before moving to the University of California at Davis, he taught at Howard University and worked at the NASA Goddard Space Flight Center. He has been a Guggenheim Fellow, received a Humboldt Senior Research Award, the AAAS Lifetime Mentor Award, and is Fellow of the American Physical Society as well as a Fellow of the AAAS. He earned his BS from Morehouse College in 1956 and his Ph.D. from The Catholic University of America in 1961. Jackson was a founder of the National Organization for the Professional Advancement of Black Chemists and Chemical Engineers. Throughout his career he has actively championed programs to increase the number of African Americans and women in science and engineering and has successfully lobbied for legislation that was funded for these purposes.

Oluyinka O. Olutoye
Baylor College of Medicine
Dr. Olutoye is Associate Professor of Pediatric Surgery at Baylor College of Medicine and Co-Director of the Texas Children’s Fetal Center. He performs fetal surgeries and also conducts his own research. One of his research interests is how wounds heal. In particular, he’s interested in the way fetuses manage to heal themselves without generating scar tissue. He hopes that understanding this fetal healing process will help scientists develop new therapies for adults—especially people who have trouble healing or who develop too much scar tissue.
Dr. Olutoye attended medical school in his home country of Nigeria. He then moved to the United States to pursue further surgical training and a Ph.D. in Anatomy at the Virginia Commonwealth University. He will continue to travel the world as a James IV Association of Surgeons 2007 Traveling Scholar, an honor that will allow him to exchange ideas with surgeons in Saudi Arabia, Great Britain, Vietnam and Australia.

Oklahoma State University
Estella Atekwana grew up in Cameroon. “My parents very much wanted me to do medicine,” she writes. “So I got into sciences with that intention. However, I took a course in geology in high school and the teacher indicated that geology was not for girls. I was challenged then to demonstrate that girls could do geology and perform the same as boys or even better. I ended up with the science award that year in chemistry, biology, and geology.” She moved to North America to study the geosciences, earning a bachelor’s and master’s in geology from Howard University and a Ph.D. from Dalhousie University in Canada. “Today, they call me Doctor and that’s fine with my parents.”
She is now Sun Chair at Oklahoma State University, where she is a leader in the new field of biogeophysics.

Shaundra B. Daily
MIT Media Lab
Shaundra B. Daily was born in 1979 in Nashville, Tennessee. In high school, an interest in being an agent for the Federal Bureau of Investigation led her to major in electrical engineering at Florida State University. But, she writes, “once I got to college, I realized that while the FBI was fascinating, what I really enjoyed was working with kids using technology.” After graduating with honors, she received a master’s in electrical engineering and moved to Cambridge, Massachusetts, to attend the Massachusetts Institute of Technology.
She is now a doctoral candidate at the MIT Media Laboratory working in the Affective Computing Group. This group seeks to “give machines skills of emotional intelligence … and … to develop technologies to assist in the development of human emotional intelligence.” Her main interests include interfaces that support affective (that is, emotional) development and technologically supported reflective practice. “Most importantly,” she writes, “I am the proud wife of Julian and mother to Layla.”

Doctoral Student, Industrial Engineering
April Savoy grew up in a small town in southwestern Louisiana, “where Creole was our first language and cooking our trademark.” She excelled in school, graduating from high school as valedictorian and then earning a perfect grade point average at Xavier University as a computer science major. “The elders of the family assured us, my cousins and I, that we would have endless opportunities to be whatever we wanted,” she writes. “I was constantly told that I could grow up to be a doctor or a computer professional. Funny, my current career path has me becoming both with a doctorate in Human Computer Interaction.” She expects to earn her Ph.D. from Purdue University’s School of Industrial Engineering in 2007.
Savoy’s areas of interest include information design, applied ergonomics, pervasive computing, and assistive technology. Above all, she writes, “I recognize my responsibility as an engineer to make the world a better place by using new technology to solve the neglected simple problems…My aim is to bridge the gap of the digital divide and provide technology to those that need it.” Savoy is a David and Lucille Packard Fellow and a Compaq Fellow.

Penn State University
Stephon Alexander was born on the southern coast of Trinidad and Tobago and moved to the Bronx in New York when he was eight. His interest in physics started four years later when his father brought home a used computer. In his quest to learn how it worked, he “discovered the words ‘Quantum Mechanics.’ Although I was mystified by the equations,” he says, “I got hooked.”
Quantum mechanics is now a part of Alexander’s daily life as an assistant professor of physics, astronomy, and astrophysics at Penn State University. His research explores the interface between fundamental physics and cosmology, and in particular addresses questions about the early universe. He plays the saxophone, and his passion for improvisational Jazz influences his work.
