Application Deadlines for Complex Biosystems
- January 9 for Fall.
Application/admission is for entry in a specific term and year. Our academic year is divided into 3 terms: Fall (August-December), Spring (January-May), and Summer (multiple sessions May-August). Some programs accept new students only in certain terms and/or years.
The program in Complex Biosystems is directed toward students interested in applying quantitative statistical and computational approaches to multiple areas of biology including human health, medical biochemistry, microbial metagenomics, ecology, evolution, and plant systems.
The first year of this interdisciplinary program offers students two semesters of laboratory rotations on diverse topics, and one semester of laboratory teaching experience. In the first year of study, the cohort of incoming students considers "big questions" in multiple areas of life sciences, and learns current technical and analytical approaches to address them.
In addition to various types of scientific communication skills and ethical approaches to research, students acquire a foundation in population, cellular and molecular life sciences; statistics; bioinformatics; and computational analysis. This unique graduate program is tailored to the student's specific desired outcomes, offering a flexible curriculum and broad interdisciplinary training.
