JOHNS HOPKINS UNIVERSITYEST. 1876

America’s First Research University

The cell is the basic unit of life. Cell biology is an integrative discipline that employs a diverse array of methods and experimental systems to study cell structure and function. By focusing on the cell, CMDB students gain a detailed understanding of the tissues and organisms that cells compose.

During their training, students will tackle outstanding challenges in cell biology, including membrane trafficking, signaling pathways, the cell cycle, nuclear organization and division, host-microbe interactions, cell motility, and the formation and regulation of biomolecular condensates. They will work with diverse model systems, including mice, fruit flies, roundworms, budding yeast, zebrafish, cephalopods, and cultured cells. Their investigations will be empowered by advanced methodologies, including quantitative single-molecule microscopy, cryo-electron microscopy and tomography, biochemistry, in vitro experiments, and in silico modeling, combined with molecular and genetic analysis.

Cell Biology Spotlight
Brenda Cesar
Brenda Cesar studies meiosis, a specialized cell division that generates haploid gametes to ensure the correct inheritance of genomes from parent to offspring. It not only allows the reproduction of all sexually reproducing organisms, but it also promotes genetic diversity. Meiosis is a highly orchestrated process that requires proper interactions between multiple proteins at the correct time and space. Any defects in this process cause gametes to have an incorrect number of chromosomes, or aneuploidy, which is the primary cause of age-related infertility, miscarriages, and genetic disorders, such as Down Syndrome. In CMDB, Ph.D. candidate Brenda Cesar uses in vitro methods to learn more about the structure and function of meiotic protein complexes.
