Ljubica Caldovic, Professor of Genomics and Precision Medicine at the George Washington University School of Medicine and Health Sciences, received her Bachelor\'s degree in chemistry from the University of Belgrade in 1988. In 1998 she obtained a Ph.D. in molecular biology and genetics from the University of Minnesota. Her research of urea cycle enzymes and disorders began in 2000 when she joined the lab of Dr. Mendel Tuchman, at the Children’s National Medical Center, and identified, cloned and characterized human N-acetylglutamate synthase, the last urea cycle enzyme to be identified in mammals. Dr. Caldovic became Assistant professor in 2004 and Associate Research Professor in 2010. Dr. Caldovic has been studying evolution and regulation of the urea cycle and using these insights for development of new therapies for hyperammonemia.
