BIOGRAPHY
Ana Paula Alonso obtained her B.S. in Biochemistry in 1998 and M.S. in Biological and Medical Sciences in 2000 from the Université Victor Segalen in Bordeaux, France. She received her Ph.D degree in 2003 from this same university, discovering a new substrate cycle in plants. After four years of postdoctoral training in seed metabolism (Michigan State University), and microbial metabolism (Institut National des Sciences Appliquées, Toulouse, France), she joined the Great Lakes Bioenergy Research Center in 2008 as a Visiting Assistant Professor to work in the exciting field of biofuel research. In 2010, Dr. Alonso moved to The Ohio State University as an Assistant Professor in the Department of Molecular Genetics; she was promoted to Associate Professor in 2016. Additionally, she is the Director of the Targeted Metabolomics Laboratory.
 
RESEARCH FOCUS
A major focus of the Alonso Lab is the regulation of carbon partitioning through central metabolism. In plants, central metabolism carries carbon to the production of valuable storage compounds, such as sugars, proteins, starch, oils, and cellulose. Therefore understanding carbon partitioning is of fundamental relevance to plant fitness, fruit quality, seed yield and germination, and to designing novel approaches for breeding and genetic engineering of crops. For this purpose, the Alonso Lab combines metabolomics and 13C-based metabolic flux analysis (aka fluxomics) - association of modern biochemistry with mathematical modeling. Their findings allowed a deeper understanding of abiotic stresses, and revealed new pathways and novel metabolic bottlenecks in important commodity crops.

Current research aims at:
i) enhancing the flow of carbon towards the production of unusual fatty acids - for biofuel and industrial applications - by metabolic engineering; 
ii) understanding the effect of biotic and abiotic stresses on plant metabolism.
