Background

Dr. Laura Schnackenberg received her B.S. degree in chemistry from the University of Arizona in 1998 and her Ph.D. in analytical chemistry from the University of North Carolina at Chapel Hill in 2003. Following completion of her Ph.D., she was hired as a postdoctoral fellow within the Division of Chemistry at NCTR in the Metabolomics group. In May 2005, she was converted to a staff fellow and in 2007 was converted to a permanent government employee. In 2006, Dr. Schnackenberg was part of the FDA Intercenter Renal Biomarkers Group that was recognized with an “NCTR Scientific Achievement Award.” The same group received the “FDA Outstanding Intercenter Scientific Collaboration Award” in 2007 and 2012. She received the “NCTR Outstanding Junior Investigator Award” in 2007. She also received a “Friends of the Department Award” from the Department of Chemistry, University of Arkansas at Little Rock in 2010, 2011, and 2013. In 2011, Dr. Schnackenberg was part of the Melamine and Cyanuric Acid Toxicity Investigative Group that received the “FDA Group Recognition Award (Agency Cross-Cutting).”  Finally, she received the “FDA Group Recognition Award (Non-Agency Cross-Cutting)” for In Silico Modeling Approaches to Polypharmacy.  In addition to her research, Dr. Schnackenberg served as co-chair for the NCTR Summer Student Research Program (SSRP) in 2015 and is the current chair for the SSRP.

Research Interests

The Biomarkers and Alternative Models Branch within the Division of Systems Biology at NCTR conducts metabolomics analyses using both nuclear magnetic resonance (NMR) spectroscopic methods and mass spectrometry (MS) methods to investigate and identify novel biomarkers of toxicity and disease in preclinical and clinical samples. Dr. Schnackenberg is a trained NMR spectroscopist and has been instrumental in the implementation of the NMR-based metabolomics program at NCTR. NMR-based metabolomics have been used in multiple studies to identify metabolite changes due to drug-induced hepatotoxicity or renal toxicity. Recently, Dr. Schnackenberg has been involved in the development of matrix assisted laser desorption ionization (MALDI) imaging mass spectrometry (IMS) to evaluate lipids, metabolites, and drug molecules in tissue slices. Such techniques will be used to identify unknowns of interest based upon statistical analysis of the NMR or MS data that are potential biomarkers of toxicity or disease. Current research includes the evaluation of maternal blood samples to identify metabolites that correlate with diagnoses of autism spectrum disorders in offspring.  MALDI IMS is being used to evaluate the distribution of doxorubicin and its metabolite, doxorubicinol, in heart tissue as well as to evaluate lipids in the brain tissue of a rodent model of Alzheimer’s disease.
