RESEARCH INTEREST Pacemaker activity, whether in the defecation motor program in C. elegans or the beating of the human heart, involves the rhythmic release of calcium. My research focuses on identifying the mechanism through which the microRNA, miR786, acts on target proteins, such as elo-2, to establish and maintain pacemaker activity in the posterior intestine of C. elegans. |

| Deepa Valsangkar | RESEARCH INTEREST The overall goal of my research is to investigate the AMPK (AMP-activated Protein Kinase)-mediated regulation of fatty acid oxidation in the regulation of mouse oocyte maturation. This research has potential applications in the assessment of metabolic status of oocytes for in vitro maturation and fertilization as well in the study of possible reproductive repercussions of drugs that modulate fatty acid metabolism such as some potential anti-obesity drug candidates.

FITTS LAB |

| Cassie Nelson | RESEARCH INTEREST My work involves exploring the cross bridge mechanisms of skeletal muscle fatigue and determining protective effects of exercise training. I have recently shown that H+ significantly decreases peak force (Po) at submaximal levels of calcium at physiological temperatures using the skinned fiber preparation. Studies will be performed to discover the exact step(s) of action of H+, Pi, and ADP in the cross bridge cycle and whether or not these factors work synergistically.

HRISTOVA LAB |
|||
| Michael Mashock | RESEARCH INTEREST My research involves the potential toxicity of Zinc Oxide nanoparticles on the ecosystem. The model system used is the symbiosis of Phaseolus vulgaris (the common bean) and Rhizobium etli, a bacteria which induces the formation of nodules which fix N2 for the plant. Our objectives are to determine the potential effects with Nanoparticles at environmentally relevant concentrations and to observe the potential effects on the symbiosis of the two organisms.

MAKI LAB |
|||
| Prince Mathai | RESEARCH INTEREST Short-chain fatty acids (SCFA) such as propionate and butyrate are crucial intermediates formed during the breakdown of complex organic matter to methane and carbon dioxide. The objective of my study is to characterize the abundance and population dynamics of syntrophic acetogens involved in the breakdown of SCFA into acetate during anaerobic digestion.

MYNLIEFF LAB |
|||
| Andrew Karls | RESEARCH INTEREST The work I do in Dr. Mynlieff's lab centers on how activated GABAB receptors modulate voltage-dependent calcium channels during neonatal mammalian development. I employ several techniques in my studies, such as electrophysiolgy, immunoblotting, and ratiometric calcium imaging. This work has implications in common human diseases, such as epilepsy. Beyond my research, I have a strong interest in teaching methodology. CONFERENCES 2009 39th Annual Meeting of Society for Neuroscience, Chicago, IL
