My career began in inorganic chemistry but my interests soon moved into public health. I began my public health training at the University of Southern California School of Medicine in the Department of Preventive Medicine. There I studied applied biostatistics and epidemiology under the direction of Dr. Wendy Mack, focusing on the effects of transdermal estrogen on vascular function and lipids in postmenopausal women. I sought to apply my skills to the emerging field of molecular epidemiology at the University of Pittsburgh Graduate School of Public Health. There I studied the Glycophorin A assay, investigating the effects of environmental exposures during pregnancy on developing fetuses under the direction of Dr. William Bigbee. Since joining Children’s National Medical Center, I’ve been able to use both my knowledge of statistics and bench science to become the primary statistician for research projects in the center.

Genetic variation in muscle and bone: The goal of much of my research has been investigating normal human genetic variation in muscle and bone. The actions and changes in both tissues is dependent on an individual’s genetic background, therefore our group has been studying single nucleotide polymorphisms (SNPs) to determine their involvement in differences in muscle and bone and differences in the responses of muscle and bone to exercise. I have focused on the analysis of SNPs in both candidate gene association and genome-wide association frameworks. Much of this work relies on population genetic principles including Hardy-Weinberg equilibrium assessments, determination of linkage disequilibrium and definition of haplotypes using the expectation maximum algorithm.
Metabolic Syndrome/Obesity: With type II diabetes reaching epidemic proportions in many westernized countries and with incidence rates increasing, it’s become clear that more needs to be done to understand how to prevent, treat and manage the disorder. Our research focuses on the normal genetic variation that plays a role in the disease. We know that many of the factors making up metabolic syndrome and diabetes have strong genetic components; therefore several collaborative studies are underway to determine how genetic differences can be used to tailor treatment to be most effective. Many of our studies are taking place in children or young adults with the hope that they have less cumulative exposure to uncontrollable factors, making phenotype assessment clearer.
Preclinical drug testing for Muscular Dystrophy: The testing of therapies intended to treat muscular dystrophies is a focus of our research, using murine models to test several promising therapeutic agents. Several murine models of human muscular disease are being used to test the efficacy of new agents. A focus of my research is the determination of the reliability and sensitivity of outcomes in the mouse model. We have collected several common outcomes, muscle strength measurements, behavioral assessments and histological measures in a large cohort of mice of several strains. With this large dataset, we are able to measure how reliable each measurement is over several experimental conditions with the hopes of developing measurements that accurately model our outcomes.
