PhD in Biology

The California Institute of Technology has a rich history of scientific and technological innovation and is globally acclaimed for its commitment to cutting-edge research. Caltech is known for its exceptional programs in science and engineering. The university offers a range of undergraduate, graduate, and doctoral programs, with an emphasis on STEM (science, technology, engineering, and mathematics) fields. What sets Caltech apart is its dedication to fostering a culture of scientific inquiry and innovation. With a faculty composed of leading scholars and a remarkable record of scientific achievement, including numerous Nobel Prizes and groundbreaking discoveries, Caltech remains at the forefront of scientific exploration and technological advancement. Its commitment to pushing the boundaries of knowledge makes it a top choice for students seeking an education deeply rooted in scientific discovery and innovation.

Graduate students in biology come with very diverse undergraduate preparation—majors in physics, chemistry, mathematics, or psychology, as well as in biology and its various branches. The aims of the graduate program are to provide, for each student, individual depth of experience and competence in a particular chosen major specialty; perception of the nature and logic of biology as a whole; sufficient strength in basic science to allow continued self-education after formal training has been completed and thus to keep in the forefront of changing fields; and the motivation to serve his or her field productively through a long career. A student may pursue major work leading to the doctoral degree in any of the following subjects: biophysics, cellular biology, developmental biology, genetics, immunology, microbiology, molecular biology and biochemistry, and systems biology. At graduation, a student may choose whether the degree is to be awarded in biology or in the selected major subject. Students who choose to work in Neurobiology may also qualify for a Ph.D. in Biology but are encouraged to enroll in the Neurobiology option.
