This proposal was submitted to the NSF-wide Professional Opportunities for Women in Research and Education (POWRE) program. The PI proposes to begin research on the sensory mechanisms coordinating chemoreception in spionid polychaetes, a common deposit-feeding invertebrate. These worms are widely distributed in soft-sediment benthic marine environments and, along with other deposit-feeders, are responsible for the bioturbation that is important to this environment. Some evidence indicates that chemoreception may coordinate sediment ingestion rate and other aspects of deposit-feeding in a variety of species. The proposed research will attempt to identify some of the physiological and molecular mechanisms used by the worms to detect chemical stimuli.

该提案已提交给全国科学基金会范围内的妇女研究和教育专业机会方案。PI建议开始对spionid polychaelus（一种常见的沉积物摄食无脊椎动物）协调化学感受的感觉机制进行研究。 这些蠕虫广泛分布在软沉积物底栖海洋环境中，沿着其他以沉积物为食的生物，造成对这一环境很重要的生物扰动。一些证据表明，化学感受可能协调沉积物的摄入率和沉积物喂养在各种物种的其他方面。拟议的研究将试图确定蠕虫用于检测化学刺激的一些生理和分子机制。
