An integrated research and education CAREER program is proposed to build a foundation for achieving the PI's career goals: to transfer biology-inspired ideas into smart, small-scale sensors, and to educate future generations of students and researchers with multi-disciplinary perspectives. Inspired by the micro-scale ears of the fly Ormia, which show remarkable sound localization ability, the research plan is to develop a new class of miniature directional microphones. This entails a new approach for sensor development via the integration of biology-inspired solutions, mechanics modeling, micro-fabrication techniques, and optical detection strategies. The mechanics model will help unravel the underlying science of the fly's hearing mechanism and develop sensor design guidelines. The low coherence interferometer based optical system will overcome the limit of state-of-the-art detection techniques. This new bio-inspired sensing paradigm for sound localization is expected to have a significant impact in areas such as health care, safety, and defense. The learning experience of undergraduate and graduate students will be enriched through an inter-disciplinary curriculum. The interests of K-12 students in science and engineering will be stimulated by involving them in multi-disciplinary research activities at the University of Maryland. Participation of underrepresented groups will be broadened through educational activities and mentoring of the Women in Engineering program.

提出了一项综合研究和教育职业计划，为实现 PI 的职业目标奠定基础：将生物学启发的想法转化为智能、小型传感器，并以多学科视角教育下一代学生和研究人员。受到奥米亚蝇的微型耳朵的启发，该耳朵表现出卓越的声音定位能力，该研究计划是开发一种新型微型定向麦克风。这需要通过整合生物学启发的解决方案、力学建模、微制造技术和光学检测策略来开发传感器的新方法。该力学模型将有助于揭示果蝇听觉机制的基础科学并制定传感器设计指南。基于低相干干涉仪的光学系统将克服最先进检测技术的限制。这种用于声音定位的新型仿生传感范例预计将对医疗保健、安全和国防等领域产生重大影响。本科生和研究生的学习经验将通过跨学科课程得到丰富。通过让 K-12 学生参与马里兰大学的多学科研究活动，他们对科学和工程的兴趣将得到激发。将通过教育活动和对工程女性计划的指导来扩大代表性不足群体的参与。
