Awards and Honors
This month's Memo from the Dean [ext. link] by Dr. Kristina Johnson, Dean of the Pratt School of Engineering, highlighted current DAILabs student Amar Chawla and DAILAbs alumni Dr. Mia Markey. Mr. Chawla is a BME Ph.D. student (advised by Dr. Samei) whose team won the Duke Start-Up Challenge "most intriguing award in the Hi-Tech/IT/Software category" for his proposal of a stereo/biplane correlation imaging approach for homeland security applications. Dr. Markey received her Ph.D. in BME in 2002 (advised by Dr. Lo) and is now an assistant professor at the University of Texas in Austin. She received the 2006 American Medical Infomatics Association (AMIA) New Investigator Award, which recognizes an individual for "early informatics contributions and significant scholarly contributions on the basis of scientific merit and research excellence." In addition, Dr. Markey just graduated her first Ph.D. student Dr. Mehul Sempat. She also received the 2006 American Society for Engineering Education Gulf-Southwest Section Outstanding Teaching Award. The ASEE is the premier organization of engineering education and its highly coveted teaching awards recognize true leaders in innovative teaching and dedication to student learning. Dr. Markey was recognized for developing innovative teaching techniques, dedication to student mentorship, and exceptional teaching performance.
We are pleased to announce that William Paul Segars, Ph.D. joined DAI Labs on October 1, 2006 as Assistant Professor of Radiology. Dr. Segars comes to us from Johns Hopkins University where he was an assistant professor in the department of environmental health sciences. He received his Ph.D. in biomedical engineering from the University of North Carolina in Chapel Hill in 2001. His expertise is in medical imaging simulation and computer phantoms. Learn more about his work in our Research section.
We congratulate the following faculty who received grant awards this year. Joseph Lo Ph.D. received an NIH/NCI R01 grant of $1,323,573 from the NIH for a 4 year research project entitled "Tomosynthesis for Improved Breast Cancer Detection."

Congratulations to Christy Shafer, who received the prestigious Clare Boothe Luce Fellowship [ext. link]. The program promotes the advancement of American women through higher education in the sciences, engineering, and mathematics. The fellowship provides financial support for three top women graduate school candidates in order to "encourage women to enter, study, graduate and teach" in the sciences, mathematics, and engineering.
DAI Labs mourns the loss of Carey Floyd
A Duke faculty member for over 20 years, Carey Everett Floyd, Jr., 52, died at home on August 28 after a lengthy battle with cancer. His love for life and for others sustained him during his illness, and he relished the time spent in conversation with family, friends, and his numerous students until his very last days. He continued the scientific work he so enjoyed right until the end of his life, even after experiencing diminished physical stamina in recent months. He was the epitome of courage, creativity, and dedication, and was greatly loved by many people.
Carey was born on March 17, 1954 in Nashville, Tennessee. He received his undergraduate degree from Eckerd College in Florida and his PhD in physics at Duke University in 1981 in the area of experimental nuclear physics. He took a postdoctoral fellowship at the Triangle Universities Nuclear Laboratory in 1982, and a subsequent postdoctoral fellowship in the department of radiology at Duke University Medical Center in 1983. He became a full professor of radiology and biomedical engineering at Duke in 1997.
An eminent scientist, Dr. Floyd made numerous significant contributions to the science of medical imaging. His early work included important contributions in nuclear medicine, including a pioneering method of reconstructing SPECT images known as the inverse Monte Carlo technique. He then became well known for many significant research efforts in digital radiography, and he established one of the pre-eminent laboratories in the world in the field of computer-aided detection and diagnosis (CAD). CAD uses artificial intelligence in conjunction with medical images and patient information in order to improve the detection and diagnosis of disease. One of his last research efforts was a novel combination of nuclear physics and medical imaging, wherein neutrons are used to stimulate gamma emission for the imaging of trace elements in the body. In recognition of his significant scientific contributions, Dr. Floyd was awarded a lifetime career achievement award from the department of radiology at Duke University on July 14, 2006.
Dr. Floyd served the scientific community well in many capacities, including several decades on grant review study sections at the National Institutes of Health. He was director of the Digital Imaging Research Division within the department of radiology at Duke from 1992 until 2004. He also was co-director of the Duke Tumor Registry, and was involved in the establishment of the new medical physics graduate program at Duke.
More important than his luminary scientific accomplishments was his superb mentorship of dozens of individual students over the past two decades. He mentored numerous PhD students in biomedical engineering, many of whom now have influential careers of their own. He truly cared for his students, and they greatly loved him. In recognition of Carey's superb mentorship of students, a new graduate fellowship at Duke University was established in his honor. The Carey E. Floyd, Jr., Graduate Fellowship will be administered by the Medical Physics Graduate Program at Duke, and will provide future generations of outstanding students the distinction of being named Floyd Fellows.
Carey was truly a renaissance man, excelling in numerous areas outside of science. He was a gifted musician, playing bass and guitar in ten bands over the years. He loved model rocketry and model trains [ext. link], and was a skilled craftsman, as evidenced by the numerous house renovation projects he undertook. He enjoyed boating, and most of all, he treasured the company of family and friends with whom he loved to converse for hours on end about interesting topics. He was a humble, caring, loyal, and courageous person who will be greatly missed by those who knew and loved him.
He is survived by his wife, Elizabeth Floyd; his father, Carey E. Floyd; and his stepmother, Ann Herbert Floyd of Nashville, Tennessee.
In lieu of flowers, the family requests contributions be made in Carey's memory to the Carey E. Floyd, Jr., Graduate Fellowship, in care of the Medical Physics Graduate Program, Duke University Medical Center, Suite 101, 2424 Erwin Road, Durham, NC 27705. Letters of condolence may be sent to the home.
