细胞生物学家对与微生物，植物和动物细胞的结构和活性有关的广泛问题感兴趣。细胞生物学家研究的许多具有根本重要性的问题包括：细胞如何响应外部刺激，例如激素，细胞运动，物质的分泌和摄取，癌细胞与正常细胞的区别，细胞成分的组装，细胞相互作用，以及细胞的精细结构。实验方法包括显微镜（电子和光学），分子遗传学，生物化学和生物物理学。细胞培养技术是细胞生物学研究的重要方面。康奈尔大学正在积极研究酵母，昆虫，鸟类，植物和哺乳动物细胞。一些部门的教师正在开展细胞生物学研究。这些教职员工分布在文理学院，农业与生命科学学院以及
Nutritional Sciences draws upon several disciplines, including biological sciences, to understand the relationships between food, nutrients, and human health. The concentration in Human Nutrition offers Biological Sciences majors courses concerned with the nature and biochemical function of essential and non-essential nutrients, nutrient requirements, the role of nutrients in gene expression, and the role of diet in both risk of chronic disease and treatment of existing disease states.<br><br>The Human Nutrition concentration requires one core course, NS 3310 Human Nutrition and Nutrient Metabolism (Spring, 4 cr), as well as at least 9 credits selected from a list of didactic NS courses related to the nature and biochemical function of essential and non-essential nutrients, nutrient requirements, the role of nutrients in gene expression, and the role of diet in both risk of chronic disease and treatment of existing disease states.<br><br>Students in this concentration are encouraged to complete a diverse set of advanced courses affording a perspective on current knowledge of nutrient requirements and function and how this knowledge can be put to use. Faculty advisors work with individual students to develop a curriculum that fits the students' interests.
