The admission criteria for applicants to the Doctor of Philosophy Degree Program in Environmental Toxicology are summarized below.
The overall requirements for the Doctor of Philosophy Degree in Environmental toxicology are summarized as follows:
After the student has completed the core coursework requirements and, if necessary, other background courses in biology, chemistry, and mathematics, he/she must pass the qualifying examinations. These examinations will consist of subject matter contained in the core coursework. A student will be allowed two attempts to pass the qualifying examinations and may petition to take them a third time. Students completing the Master of Science degree in Environmental Toxicology at TSU will be exempt from this requirement.
The residency requirement may be met by one of the following:
Enrollment in a minimum full-time course load in two consecutive semesters or a minimum full-time course load taken in a regular semester immediately preceding or following full-time enrollment in each of the summer terms.
As a condition for admission to doctoral candidacy, the student must complete all course work, except for the dissertation research, satisfy residency, pass the qualifying examination and successfully defend his/her research proposal.
A comprehensive examination is required of all doctoral students. It is recommended that the comprehensive examination be taken in the same semester of the student’s dissertation defense. However, it can be taken after the all course work in the degree plan has been satisfied, the qualifying examinations have been passed and the dissertation proposal has been approved and accepted by the graduate school. The comprehensive examination will be composed of test items from the student’s specialization area and questions from the basic core and related courses in environmental toxicology. The student will be allowed two attempts to pass the comprehensive examination and may petition the department to take it a third time.
The Ph.D. degree is primarily a research degree. The student is expected to demonstrate the ability to design a research project, implement it, contribute new knowledge to the field of study, and write an acceptable dissertation. The dissertation topic and nature and extent of the research will be recommended by the student and his/her adviser for approval by the dissertation committee.
The format of the dissertation, described in a booklet from the Office of the Graduate School, must be followed. The dissertation must be defended before the committee in an oral examination. Certification of successful completion of the oral examination requires the signature of all members of the dissertation committee. A student who fails the final oral examination on the dissertation may petition the Dean of the Graduate School through the department for a second attempt to pass the examination. All changes in the dissertation suggested by the committee after the Oral Examination must be made before the dissertation can receive the final approval of the Graduate School. In addition to the dissertation, the student is required to condense the dissertation or a portion of it into a paper suitable for publication in a refereed journal. This paper must accompany the dissertation when it is presented to the members of the committee. In addition, an abstract not exceeding 350 words must be prepared for submission to University Microfilms Incorporated.
The objective of the environmental toxicology program is to provide training which will enable students to apply the principles and methods of the physical and biological sciences to the study of toxicants as a basis for solving problems associated with the presence of toxicants in the environment. Although the emphasis in the master’s program will be on course work, the Ph.D. degree curriculum is designed to produce graduates who are highly skilled in designing and implementing research studies, analyzing data, and applying results that may be used in the formulation of policies and plans for a healthier environment.
Students in both the M.S. and Ph.D. degree programs will study the properties, fate, biological effects, detection and regulation of natural and/or man-made toxicants present in the environment. Toxicants may include air, water and soil pollutants, such as pesticides, industrial chemicals, and poisons produced by microbes, plants, and animals. The program for Ph.D. degree students will have a strong emphasis on research.
Students may pursue research problems in the following areas: air, water, soil pollution; genetic toxicology; chemistry and fate of pesticides; pathogenesis of toxicants; risk assessment, and natural toxicants.
After being admitted to a program leading to the Doctor of Philosophy degree, a student will be allowed seven (7) calendar years in which to complete all of the requirements for the degree, including transferred credit and prior credit at Texas Southern University. Continuation in the doctoral degree program beyond the seven-year limit must be approved by the student’s doctoral degree advisory committee and the dean of the Graduate School.
The maximum time allowed to complete the doctoral program, including an approved extension is nine (9) calendar years. This time limit does not include work done as part of the requirements for a master’s degree or that needed to complete any course work deficiencies as noted by a probationary admission.
