The PhD Program in Biology (Environmental Biology Track)

The environmental biology track is designed to accommodate students of various science backgrounds with rigorous training in environmental sciences/environmental biology. With the help of a faculty advisor, a cohesive course of study is designed from a variety of research interests. Faculty in the department conduct research in these related areas:

Admission Requirements

Test of English as a Foreign Language (TOEFL official test score) is required for international applicants. For more information regarding minimal TOEFL scores go to Graduate Admissions.
The stated interests of a prospective student must coincide to an acceptable degree with the faculty specialties represented in the program. The Biology Graduate Committee in conjunction with the director of Graduate Programs in Biology is responsible for reviewing applications and for recommending candidates to the dean of graduate studies.

Degree Requirements

Soon after entering the program, the student will be assigned an academic advisor, who must be a full-time member of the Biology Department faculty. Within six months, the student and academic advisor will choose an Academic Advisory Committee (AAC) and will submit this proposed committee for approval to the graduate program director (GPD) and the Biology Graduate Committee, which oversees all aspects of graduate study in environmental biology. The AAC will comprise the academic advisor and two additional members in the student’s area of interest. The student, in consultation with the AAC, will plan an appropriate course of study. During the first year of graduate study and until a dissertation committee has been established, the AAC will monitor the student’s progress. The academic advisor and the student will provide a yearly progress report to the GPD and the Graduate Committee. The student can change his or her academic advisor or rearrange his or her AAC with the approval of the GPD. Current course work requirements, as revised in fall 2007, are below.

For the PhD in biology/environmental biology, 60 credits are required, distributed as follows:

Required Core Courses - 12 credits

Biol 650 Scientific Communication

*Students have generally gained more benefit from Scientific Communication if it is taken in the first year.

Nine additional credits from the following courses:

Biol 628 Microbial Ecology
Biol 635 Population Genetics and Diversity
Biol 636 Advanced Ecosystem Ecology
Biol 639 Conservation Biology
Biol 641 Quantitative Population Modeling
Biol 642 Biogeography
Biol 648 Invasive Species: Ecology, Evolution and Management
Biol 652 Biological Diversity and Evolution
Biol 658 Environmental Physiology

Elective Courses - 12 credits
Subject to the approval of the student’s AAC or dissertation committee.
Student may take Directed Readings (Biol 672) for up to 3 credits of the electives.
Up to six credits may be transferred from another program in accordance with the policy of the Office of Graduate Studies.

Journal Readings - 4 credits

Biol 653 Current Literature in Biology

These courses are designed to help students stay abreast of recent developments through reading current literature and to provide opportunities for public speaking.

Research Credit - 32 credits

Biol 899 Dissertation

Up to 5 of these credits can be replaced by elective course credits, subject to the approval of the student's AAC.
In general, formal course work should be completed within the first four semesters.


Students are required to participate in the teaching program as teaching assistants for at least two semesters. The teaching responsibility is intended to enhance the experience and skills of the PhD candidate.


To continue in the PhD program, the student must maintain a GPA of 3.0, and may not receive a grade of “C” in more than one course.

Written Comprehensive and Oral Qualifying Examinations

Students must pass two examinations before they undertake research at the doctoral level:

a written comprehensive examination to test the student’s command and knowledge of four specific areas of biology**
a subsequent oral qualifying examination based on:

The written comprehensive examination may be taken at the end of the student’s first year, or after the completion of at least 18 credits of course work; and it should generally be taken by the end of four semesters or 36 credits of course work. The student will defend four areas, drawn from the array of graduate courses offered in the department or from other areas acceptable to the AAC and approved by the Graduate Committee.
A student who fails the written examination may, at the discretion of the academic advisory committee, be permitted a second and final written examination after six months.

A student failing the examination a second time may either:

  1. withdraw from the program, or
  2. formally petition the AAC to work toward a master’s degree in biology, in biotechnology and biomedical science, or in environmental sciences.

A student cannot continue in the PhD program after a second failure of the comprehensive examination.
**Generally, within one month following the written exam, the student should submit a brief description of his or her dissertation proposal to the AAC and the GPD. Before taking the oral examination, the student should also confer with members of the AAC on the soundness of the proposal. The student should also discuss, with the individual members of the AAC, the possible deficiencies in the written exam. The oral qualifying exam should be scheduled, generally within one month following the submission of the dissertation proposal.
On successfully completing the qualifying examination, the student becomes a candidate for the PhD degree in Environmental Biology. The student is allowed up to five more years to complete and successfully defend a scholarly dissertation.

Departmental Presentation

Approximately nine to twelve months after the student’s advance to candidacy, the student will present a seminar, based on his or her work in progress, to the entire department.

Dissertation Committee

After becoming a candidate for the PhD, the student must choose a dissertation advisor and committee. The dissertation committee will generally, but not necessarily, comprise the three members of the AAC and one member from outside the department. With the approval of the GPD and the Graduate Committee, faculty from outside the Biology Department or non-UMass Boston faculty will be permitted to co-sponsor a student’s dissertation work.

Dissertation Defense

A final public dissertation defense will be administered by a dissertation panel comprising at least five members including

The defense will be chaired by the student’s dissertation advisor, and will be scheduled after the student has submitted an advanced draft of the manuscript to the dissertation panel and after the panel has agreed that the student is ready to defend it.

Transfer Credit Policy

Applicants who have completed appropriate graduate course work at other accredited institutions may transfer the equivalent of six credits toward UMass Boston graduate degree requirements from courses in which the applicant received a grade of B or higher, provided these are courses that have not been used to fulfill requirements for another degree, and were completed no more than seven years before the applicant's matriculation of UMass Boston. Transfer credit is subject to the final approval of the graduate program director and the Dean of Graduate Studies.

Costs and Financial Aid

As a public university, the costs of attending UMass Boston are moderate, especially for students who qualify as residents of Massachusetts. Financial aid is available in the form of grants, loans, and a limited number of assistantships that provide a stipend and remission of tuition.
