The goal is for the candidate to embark on a career transformation by acquiring critical knowledge and skills in biomedical sciences and become a productive and successful investigator in emerging biomedical areas with a unique set of expertises. One of the important components consists of projects in genetic phenotyping of small animals using in vivo bioimaging. The research will first tackle the technically easier problem of measuring and analyzing regional fat distribution in mice so as to identify potential subgroups with specific health problems; e.g., increased levels of visceral fat have been associated with insulin resistance, cardiovascular disease, and other metabolic syndromes. Building on this experience, the project will proceed to the identification of skeletal phenotypes using 3D micro-CT imaging. Not only will image segmentation be a challenge, a paradigm for extracting complex anatomical information will be created, as for example from a mouse skeleton, and clustering data into phenotypes for comparison with genotypes. This paradigm will set a standard and open new possibilities in deriving biomedical knowledge from mouse models.

目标是让候选人通过获得生物医学科学的关键知识和技能，成为新兴生物医学领域具有独特专业知识的富有成效和成功的研究者，从而开始职业转型。其中一个重要组成部分是利用体内生物成像技术进行小动物遗传表型研究。这项研究将首先解决技术上比较容易的问题，即测量和分析小鼠体内的区域脂肪分布，以确定具有特定健康问题的潜在亚群；例如，内脏脂肪水平升高与胰岛素抵抗、心血管疾病和其他代谢综合征有关。
