Department of Ecology and Evolution
The Department of Ecology and Evolution provides training for research and teaching in the ecology, evolution and behavior of whole organisms, at the levels of the organism, the population, and the ecosystem. The research interests of our faculty include molecular evolution, population genetics, quantitative genetics, animal behavior, plant and animal ecology, evolutionary theory, systematics, paleontology, and related subjects. Individual levels of study range from molecules to communities. A common theme is the conduct of studies in a rigorous ecological and conceptual context, and the faculty share an interest in the architecture of populations, species and communities.
The department stresses scientific breadth and the interrelations between various specialized fields. Students are encouraged to approach basic biological problems with the most appropriate techniques: biophysical, biochemical, mathematical, physiological, or organismal. Departmental laboratories are equipped for a wide variety of contemporary research methods. Courses in other programs may be taken for credit in ecology and evolution for example, in the Departments of Organismal Biology and Anatomy, Biochemistry and Molecular Biology, Molecular Genetics and Cell Biology, Statistics, Geophysical Sciences, Anthropology, and Chemistry. Many students in the Department of Ecology and Evolution participate in interdepartmental programs in genetics, cell biology, developmental biology, population biology, theoretical biology, and evolutionary biology, and in these programs dissertation research may be co-sponsored by faculty from different departments. Collaboration is also maintained with the Field Museum and the Shedd Aquarium for students interested in research in systematics, taxonomy, and evolutionary biology, and with the Brookfield Zoo for basic research in conservation and behavior involving zoo animals. Possibilities also exist for field studies in Central America, Africa, and other regions of the earth.
Program of Study
Most students in the Department of Ecology and Evolution complete their Ph.D. program in about five years, though students entering with a master’s degree may finish in slightly less time. A student advisory committee advises all incoming and second year students on academic and research concerns. The first and second years consist largely of course work and individual reading courses, aiming toward successful completion of an oral general knowledge examination by the spring quarter of the first year, supervised by the student advisory committee. The student and faculty advisor in consultation with the department chair, then choose a five member faculty doctoral committee, scheduling a defense of the dissertation research proposal by the end of the second year of study. Work in subsequent years shifts to dissertation centered research and, finally, preparation and defense of the Ph.D. dissertation. All students are required to register to be a supervised teaching assistant in two approved courses during their tenure in the doctoral program. While there is no master's degree program in the department, students may elect to receive the S.M. degree upon successful completion of their dissertation proposal defense.
Entering students are expected to have received a broad undergraduate training in biology, and a good background in related quantitative subjects, such as chemistry, statistics and calculus. Students who are admitted without having fully satisfied these requirements will be required to remedy their deficiencies by taking appropriate courses during their first two years in the graduate program.
General Knowledge Examination
Each first year student will be expected to pass an oral general knowledge examination during the first year of study, generally no later than the 10th week of the spring quarter. This examination session shall be attended by all three members of an examination committee appointed by the student advisory committee. The goal of the examination will be to assess each student’s general knowledge of key concepts, processes and issues in ecology and evolutionary biology, as covered in the courses recommended to the student by the student advisory committee during the student’s first year in the program.
Dissertation Proposal Defense
This examination consists of the submission of a written Ph.D. research proposal and an oral presentation of the proposal in a public or closed/private seminar format, followed by a closed discussion and examination on the proposal presentation with the faculty committee chosen by the student and the chair of the department. Students are expected to schedule the dissertation proposal defense before the end of their second year.
Doctor of Philosophy
Upon successful completion of the dissertation proposal defense and admission into candidacy for the Ph.D., students work closely with the faculty advisor and dissertation committee on the dissertation project. During the period of two to three years in which students do primary original research, they also participate in seminars, discussion groups, and professional meetings and conferences, leading to the completion of the written Ph.D. dissertation. The Ph.D. in ecology and evolution is awarded based upon:
- Submission of a written dissertation based on original research, which must be approved by the faculty adviser and dissertation committee.
- Presentation of a public seminar based on the dissertation research.
- Following the public seminar, successful performance during an oral examination by the dissertation committee and other relevant faculty.
- Acceptance of the approved written dissertation by the University Dissertation Office in compliance with that office’s regulations.
We strongly advise students considering application to the department to begin preparation of their application early in the autumn quarter, so that all materials will arrive by the December 1 deadline. The department requires GRE General Test scores from all applicants, and recommends submission of GRE subject test scores in biology. Foreign applicants whose first language is not English also must submit TOEFL test scores with their application materials.

Ecology and Evolution Courses
ECEV 31100. Evolution of Biological Molecules. 100 Units.
The course connects evolutionary changes imprinted in genes and genomes with the structure, function and behavior of the encoded protein and RNA molecules. Central themes are the mechanisms and dynamics by which molecular structure and function evolve, how protein/ RNA architecture shapes evolutionary trajectories, and how patterns in present-day sequence can be interpreted to reveal the interplay data of evolutionary history and molecular properties. Core concepts in macromolecule biochemistry (folding and stability of proteins and RNA, structure-function relationships, kinetics, catalysis) and molecular evolution (selection, mutation, drift, epistasis, effective population size, phylogenetics) will be taught, and the interplay between them explored.

ECEV 31800. Cancer Biology 6: Cancer Genomics and Systems Biology. 100 Units.
Cancer is a genetic disease characterized by the complex actions and interactions of environmental factors, multiple inherited and acquired genetic factors, networks, and cells. Together, they predispose some individuals to develop cancer, protect others against it despite lifelong exposures to carcinogens, and determine the likelihood of response to therapy. This inherent complexity presents constant challenges for diagnosing and treating patients with cancer. Until recently, it has not been possible to explore the myriad genetic and biological factors varying among individuals that may account for the differences in susceptibility to cancer, the response to treatment, and the trajectory of disease. With the advent of new genome-wide and high-throughput technologies, we are now beginning to unravel the genetic underpinnings of cancer. A systems biology approach towards cancer examines the many components of the disease simultaneously. It is hoped that findings resulting from systems biology studies will form the foundation for “personalized medicine.” The goal of this course is to teach students to manipulate and analyze the enormous datasets generated by genome-wide platforms. The course is divided into four modules, each of which is dedicated to an in depth exploration of a single platform: 1) genome-wide association studies (GWAS); 2) next-generation sequencing 3) systems analysis of proteins; and 4) integrated data analysis. Modules are comprised of both lectures and labs, and for each module, there is a student-led presentation of seminal papers demonstrating the translational potential of each technology to the investigation of human disease. Although the focus of the course is cancer, the course has relevance to students interested in using systems biology strategies to investigate a variety of complex diseases. The course is complementary and non-overlapping with material covered by other Cancer Biology courses.
