分子和细胞生物学（MCB）的研究重点强调了现代细胞生物学研究与医学和社会的交汇。它扎根于对生物学过程的研究，该研究基于对分子及其在细胞和组织中的相互作用以及基因组如何协调细胞行为的研究。因此，MCB非常适合希望研究正常生理和疾病核心分子和细胞过程的学生。为此，MCB选矿人员将探索涉及基因组学，系统生物学，免疫学，癌症生物学，微生物组，全球健康和传染病的当代学科。通过课程学习和动手研究，学生将有机会研究现代生物学和医学中许多核心问题。MCB教职员工致力于支持本科生研究，我们鼓励学生加入MCB教职员工的实验室
The Molecular and Cellular Biology (MCB) concentration emphasizes the intersection of modern cellular biology research with medicine and society. It is rooted in the investigation of biological processes based on the study of molecules and their interactions in the context of cells and tissues, and how the genome orchestrates cell behavior. MCB is therefore ideally suited to students who wish to study molecular and cellular processes at the heart of both normal physiology and disease. In doing so, MCB concentrators will explore contemporary subjects spanning genomics, systems biology, immunology, cancer biology, the microbiome, global health, and infectious disease. Through coursework and hands-on research, students will have the opportunity to investigate many of the questions central to modern biology and medicine. The MCB faculty is dedicated to supporting undergraduate research, and we encourage students to join the laboratory of an MCB faculty member or a laboratory in one of the Harvard-affiliated centers. We consider the senior thesis to be the capstone academic experience, and the concentration will provide extensive support to seniors to make thesis writing an enriching experience. MCB students are also assigned a Tutor from the Board of Tutors in Biomedical Sciences to provide both intellectual support and professional mentorship. An MCB student typically meets with his or her assigned Tutor regularly throughout the semester, either individually or in small groups, to read and discuss primary literature or relevant texts tailored to the student's interests. MCB graduates will be informed citizens who can understand and evaluate the impact of new research discoveries in the life sciences as they unfold at a breathtaking and accelerating pace. Graduates will stand poised to pursue a broad range of careers in biological and medical research, public and global health, science policy, law and intellectual property, business, education, and science writing.
