Welcome

This is an extraordinary time to be involved in biomedical research. New technologies are rapidly changing our understanding of the molecular and cellular basis of life, with dramatic implications for how we treat human disease. Members of the Department of Molecular, Cell and Developmental Biology (MCDB), along with affiliated faculty in the departments of Biomolecular Engineering, Chemistry and Biochemistry, Microbiology and Environmental Toxicology, and Physics, are participating in an extraordinary revolution in biomedical science.

A broad spectrum of cutting-edge research tools are being employed to tackle problems in key areas that include: the structural and functional role of RNA in regulation of gene expression; chromatin biology and epigenetic control of genes; the cell biology of the cytoskeleton and the cell cycle; decisions controlling embryogenesis and organ development; and developmental neurobiology. The insights generated by this basic research enable new strategies for treatments of aging disorders, birth defects, neurological diseases, cancer, and other human ailments. The department offers a spectrum of courses that reflect the exciting new developments and directions in these fields and trains students to participate in these exciting fields.

Invited speakers are widely recognized experts in their respective fields whose research programs have broad appeal to scientists working within and across biological subdisciplines, including thesis defenses, third year talks, and special seminars. 

Our seminars (Biol 291 and 292) occur every Monday and Friday of the academic year 12:00-1:05 PM in Natural Sciences Annex 101 (unless otherwise noted).

Meet the Faculty

The Department of Molecular, Cell and Developmental Biology has 38 faculty members whose research addresses the question of how information in DNA is packaged, read, and interpreted in living cells, how those cells are built may be regenerated, and how cells work together to comprise an organism.

Research in this area of biology represents the largest and most active scientific enterprise in human history, with hundreds of thousands of researchers engaged around the world, making discoveries with instant application to human health and the environment. Our department is recognized as among the world leaders in this extremely large enterprise.

At Santa Cruz, we collaborate in research and educational programs with our colleagues in the Departments of Chemistry & Biochemistry, Physics, Biomolecular Engineering in the School of Engineering, and Microbiology and Environmental Toxicology.


Prospective Graduates

Our department has a long record of outstanding interdisciplinary graduate training. We have NIH and other training grant support, fellowships and teaching assistant positions. Students are admitted through the Program in Biomedical Sciences and Engineering, a multi-track interdisciplinary admissions program with over 67 participating faculty members and laboratories.
