Joanna Sigfred Fowler (born August 9, 1942) is a scientist emeritus at the U.S. Department of Energy's Brookhaven National Laboratory in New York. She served as professor of psychiatry at Mount Sinai School of Medicine[1] and director of Brookhaven's Radiotracer Chemistry, Instrumentation and Biological Imaging Program.[2] Fowler studied the effect of disease, drugs, and aging on the human brain and radiotracers in brain chemistry. She has received many awards for her pioneering work, including the National Medal of Science.

Life and education

Fowler was born in Miami, Florida, and attended the University of South Florida, where she received her bachelor's degree in chemistry in 1964. There, she worked in the laboratories of Jack Fernandez. Fowler received her Ph.D. in chemistry from the University of Colorado in 1967 and did her postdoctoral work at the University of East Anglia in England and at Brookhaven National Laboratory. Fowler worked at Brookhaven National Laboratory from 1969 until her retirement in January 2014. She is an emeritus professor in the Chemistry Department at Stony Brook University.[3]

She is married to Frank Fowler, an emeritus professor of organic chemistry at Stony Brook University.

Research and achievements

Fowler's research has led to new fundamental knowledge, development of important scientific tools, and has broad impacts in the application of nuclear medicine to diagnostics and health. She has worked for much of her career developing radiotracers for brain imaging to understand the mechanisms underlying drug addiction. Most recently, she has been engaged in developing methods to understand the relationship between genes, brain chemistry, and behavior.[4]

In 1976, Fowler and her colleagues designed and synthesized a radioactively "tagged" form of sugar that is now used widely to study brain function and also to diagnose and plan treatment for cancer. She also developed another radiotracer, as these "tagged" molecules are called, that first showed that cocaine's distribution in the human brain parallels its effects on behavior.

Fowler played a central role in the development of a fluorine-18-labeled glucose molecule (FDG) enabling human brain glucose metabolism to be measured noninvasively. This positron-emitting molecule, together with positron emission tomography (PET) imaging, has become a mainstay for brain-imaging studies in schizophrenia, aging and cancer.

Another of her major accomplishments was the development of the first radiotracers to map monoamine oxidase (MAO), a brain enzyme that regulates the levels of other nerve-cell communication chemicals and one of the two major enzymes involved in neurotransmitter regulation in the brain and peripheral organs. Using these radiotracers, she discovered that smokers have reduced levels of MAO in their brains and lungs. This may account for some of the behavioral and epidemiological features of smoking, such as the high rate of smoking in individuals with depression and drug addiction, two conditions involving poor nerve-cell communication, and has led to many studies on reduced MAO and smoking.[4]

Fowler holds eight patents for radiolabeling procedures.[1]
