DESCRIPTION (provided by applicant): The candidate for the proposed "Mentored Quantitative Research Career Award" has multidisciplinary training and research experience in polymer chemistry and materials science. His expertise in the field of polymer chemistry, material science and vibrational spectroscopy has placed him in a unique position to apply this strong knowledge base to the area of biomaterials and biomedical/tissue engineering. The program outlined in this career development application adds a biological/clinical foundation to the candidate's background. The candidate will build his research knowledge, experience and understanding of the biological aspects of oral tissue development, disease processes involving oral and craniofacial tissues, and molecular biologic techniques through a multidisciplinary program that combines education, mentoring and completion of an innovative research study. The candidate's long-term goal is to establish himself as a productive, independent research scientist in biomaterials/tissue engineering with a specific focus on the development of replacement materials for oral and craniofacial tissues. Research activities will be completed in the newly created Center for Research in Interfacial Structure and Properties at the UMKC School of Dentistry. A fundamental goal of the Center, which is under the direction of the candidate's mentors: Drs. Paulette Spencer and J. Lawrence Katz, is to provide a research environment that serves as a catalyst for collaborative investigations focused on applying the principles of biological systems to the hierarchal design, synthesis and application of biomaterials. The candidate proposes to use novel high-resolution analytical techniques for direct in situ detection of the molecular structure and micro-mechanics of the bond formed at the adhesive interface with caries-affected dentin and sclerotic dentin. The work will identify the structure/property characteristics that inhibit the formation of a durable bond at the adhesive interface with these clinically relevant dentin substrates. Results from this work will provide critical, new insight into failure mechanisms at the dentin/adhesive interface; failure that can ultimately lead to premature breakdown of the composite restoration.

描述（由申请人提供）：拟申请“导师定量研究事业奖”的候选人具有高分子化学和材料科学的多学科培训和研究经验。他在聚合物化学、材料科学和振动光谱学领域的专业知识使他处于一个独特的位置，可以将这些强大的知识基础应用于生物材料和生物医学/组织工程领域。在这个职业发展申请中概述的程序为候选人的背景增加了生物学/临床基础。候选人将通过结合教育、指导和完成创新研究的多学科项目，在口腔组织发育的生物学方面、涉及口腔和颅面组织的疾病过程以及分子生物学技术方面积累研究知识、经验和理解。候选人的长期目标是在生物材料/组织工程领域成为一名富有成效的独立研究科学家，专注于口腔和颅面组织替代材料的开发。研究活动将在UMKC牙科学院新成立的界面结构和性能研究中心完成。该中心的一个基本目标是在候选人导师的指导下。paullette Spencer和J. Lawrence Katz，旨在提供一个研究环境，作为合作研究的催化剂，专注于将生物系统原理应用于生物材料的分层设计、合成和应用。该候选人建议使用新颖的高分辨率分析技术来直接原位检测与龋病牙本质和硬化牙本质在粘合剂界面形成的键的分子结构和微观力学。这项工作将确定抑制这些临床相关牙本质基质在粘接剂界面形成持久粘合的结构/性质特征。这项工作的结果将为牙本质/粘接剂界面的失效机制提供关键的新见解；可能最终导致复合材料修复过早损坏的故障。
