The research objective of this Faculty Early Career Development (CAREER) award is to understand the coupled laser and ultrasound-material interactions in a novel ultrasound-assisted, water-confined laser micromachining process, which combines laser machining with in-situ ultrasound in water. The approach includes physics-based modeling of the coupled laser and ultrasound-material interaction, time-resolved observation of the machining process, and characterization of the machined workpiece microstructures and mechanical properties. The educational objective of this project is to integrate the research in micro manufacturing with education, community outreach and minority student involvement. The approach includes curriculum development by incorporating research results, graduate students mentoring, undergraduate and minority high school student involvement through a project class and an academy program, interfacing with local schools and museum, and teaching skill improvement. If successful, this project will provide an improved understanding of the coupled laser and ultrasound material interactions in the ultrasound-assisted water-confined laser micromachining process, which can potentially avoid or greatly reduce current micromachining defects. This can lead to better product quality, increase the manufacturing efficiency, and reduced cost. This will have a broad impact on medical, electronics, automotive and many other areas, which have a rapidly growing need for micromachining. The educational activities will improve education in the manufacturing area, strengthen the university's connections with local communities, enhance the public awareness to laser technologies, and attract more high school and minority students to the university science and engineering programs. Research results dissemination can be effectively realized through journal and conference publications, and the interactions with industries.

该学院早期职业发展（CAREER）奖的研究目标是了解新型超声辅助水限制激光微加工工艺中激光和超声材料的耦合相互作用，该工艺将激光加工与水中原位超声相结合。该方法包括基于物理的耦合激光和超声材料相互作用建模、加工过程的时间分辨观察以及加工工件微观结构和机械性能的表征。该项目的教育目标是将微制造研究与教育、社区外展和少数族裔学生的参与相结合。该方法包括通过整合研究成果来开发课程、研究生指导、本科生和少数族裔高中生通过项目班和学院项目参与、与当地学校和博物馆交流以及教学技能提高。 如果成功，该项目将加深对超声辅助水约束激光微加工过程中耦合激光和超声材料相互作用的理解，这有可能避免或大大减少当前的微加工缺陷。这可以提高产品质量、提高制造效率并降低成本。这将对医疗、电子、汽车和许多其他领域产生广泛影响，这些领域对微加工的需求迅速增长。 这些教育活动将改善制造业领域的教育，加强大学与当地社区的联系，提高公众对激光技术的认识，并吸引更多的高中生和少数民族学生参加大学科学与工程课程。 通过期刊、会议出版物以及与行业的互动，可以有效实现研究成果的传播。
