Research Interests:

My research has focused on two agendas: First, we investigate the impact of maternal diet and exercise on the cardiometabolic health of offspring. We wish to probe the mechanisms by which maternal exercise before and during pregnancy is a modifiable maternal behavior that may reduce the development of obesity-linked cardiometabolic dysfunction in offspring. Second, we have studied diet-induced obese mouse models to better understand the role of nutritional supplementation in type 2 diabetes, particularly skeletal muscle adaptation. An interdisciplinary approach, including functional measurement (echocardiography, pressure-volume hemodynamics, and myocyte contractile properties), mitochondrial function, gene expression, biochemical assays, immunohistochemistry, and histology has been used to investigate these topics.



Major Laboratory Equipment:

Echocardiography- in vivo cardiac function measurement

Echocardiographic measurement is performed under light anesthesia to measure cardiac function








O2K-FluRespirometry: Mitochondrial functional measurement

Mechanical preparation of cardiac fibers to measure mitochondrial function. Cardiac tissue is separated into small bundles ( 1mm diameter and about 2 mm length strip) to prepare saponin-skinned fibers











Mitochondrial function measurement using O2k-FluoRespirometry







Real-time quantitative PCR machine to measure gene expression






Chemiluminescence detection system to obtain an image

Cryostat and A fluorescent microscope: Immunofluorescence Analysis

Frozen muscle sections are cut into 8mm thick cryosection to characterize the skeletal muscle








Antibody treatment to the cryosection – primary antibodies were added to the muscle section to visualize the muscle fiber









Different colors indicate different muscle fiber (Blue- Type I, Green- Type IIa, Red- Type IIb, Unstained- Type IIx)
