Lorence grew up in Mexico, and joined ABI/A-State in 2005. She was at Virginia Tech before coming to Arkansas. Her life-long passion is biochemistry. Lorence was part of the team that in 2004 published the discovery of a new biosynthetic pathway for vitamin C in plants. At A-State Lorence leads a research team involved in understanding how plants make this essential vitamin using myo-inositol as the main building block. Her group also studies how vitamin C delays aging and contributes to confer plants tolerance to stresses. Her current model plants of study are: Arabidopsis, tobacco, tomato, and rice. Since 2011 she also leads the A-State Plant High Throughput Phenotyping Facility.
