Peggy Ozias-Akins is a Distinguished Professor at the University of Georgia known for her work on plant breeding, especially in peanuts. She was elected a fellow of the American Association for the Advancement of Science in 2009.
Ozias-Akins received a B.S. in from Florida State University in 1975. She earned her Ph.D. in botany from the University of Florida in 1981.[1]
In 1986 Ozias-Akins moved to the University of Georgia as a faculty member, and in 2017 she was named a distinguished research professor at the University of Georgia.[2]
Research
Ozias-Akin is known for her work using molecular tools to change how crop plants such as peanuts or millet are grown. Her early research examined how wheat plants[3] and peanuts[4] reproduce using somatic embryogenesis, a process where a plant is formed from a single cell, a somatic embryo. Her early work on peanuts sought to use genetic techniques to reduce a peanut plants susceptibility to diseases.[5] She has used a species of grass, pearl millet, to examine how plant cells produce a seed that is an exact copy,[6] a process known as apomixis.[7] Ozias-Akin began research on genetically modified peanuts in 2009.[8] She sought to eliminate allergens in peanuts, but ultimately determined that was not a viable path to reducing peanut allergies.[9][10]
