Scientists Discover Cellular Stress Enzyme That Might Play Key Role in Neurodegenerative Diseases Such as ALS
An enzyme called MARK2 has been identified as a key stress-response switch in cells in a study by researchers at Johns Hopkins Bloomberg School of Public Health.
Discovery Illuminates How Cell Growth Pathway Responds to Signals
A basic science discovery by researchers at the Johns Hopkins Bloomberg School of Public Health reveals a fundamental way cells interpret signals from their environment and may eventually pave the way for potential new therapies.
What We Do
Our Department strives to increase knowledge of cellular processes—normal and abnormal—at biochemical and molecular levels. We train highly qualified scientists who, through research, teaching, and service, continue to provide new insights into biomedical issues with a profound impact on public health.
Department Highlights
Founding Department
In 1917, we were the Department of Chemical Hygiene—our name has changed but not our drive for cutting-edge research.
Basic lab science with a public health perspective
Our research labs are uncovering the fundamental biochemical and molecular mechanisms at the foundations of health.
Teaching and training focus
We are committed to providing our students with training and mentoring so they can excel in a challenging but supportive environment.
From Cancer to CRISPR
Our faculty research—and teach—diverse topics across the breadth of biochemistry and molecular biology.
Our Programs
As a basic research department within the #1 public health school, the Department of Biochemistry and Molecular Biology thrives at a unique intersection of basic science, medicine, and public health.
We offer a doctoral and two master’s degree programs. We are also part of an online interdepartmental Master of Arts in Public Health Biology.
Master of Science (ScM)
Graduate-level program that blends coursework in the first year with rigorous training in laboratory research that culminates in a comprehensive research project in the second
Master of Health Science (MHS)
Graduate-level preparation focused on the intersection of basic science and medicine, with curriculum offerings from a public health perspective and opportunities for students to broaden their experience
Doctor of Philosophy (PhD)
Doctoral-level program focused on the biochemical and molecular bases of normal and abnormal cellular processes that trains students to be successful independent scientists and provide new insights into biomedical issues with profound impacts on public health
Ashi Weeraratna, PhD,
studies how cancer cells move to distant sites and how changes in the normal cells around a tumor contribute to their movement, especially as we age.
