The Molecular and Cellular Biology (MCB) program focuses on bridging cutting-edge cellular biology research with medical applications and societal impacts. Grounded in examining biological mechanisms through molecular interactions within cells and tissues, it explores how genetic information directs cellular functions. This concentration is perfect for students passionate about understanding fundamental molecular and cellular phenomena in both healthy systems and disease states. MCB students engage with modern topics including genomics, systems biology, immunology, cancer research, microbiome studies, global health challenges, and infectious diseases. The curriculum combines classroom learning with practical research, allowing students to tackle key questions in today's biological and medical sciences. Faculty members actively support undergraduate research, welcoming students to join labs within MCB or Harvard-affiliated institutions. The senior thesis serves as the culminating academic project, with comprehensive support provided to ensure a rewarding experience. Each MCB student receives guidance from a Biomedical Sciences Tutor for academic enrichment and career mentorship, meeting regularly for literature discussions tailored to individual interests. MCB alumni emerge as scientifically literate citizens capable of critically assessing breakthroughs in the rapidly evolving life sciences. Graduates are well-prepared for diverse career paths in research, healthcare, policy, law, business, education, and science communication.
