PhD in Integrative Life Sciences – Psychiatric, Behavioral, & Statistical Genetics Concentration (PhD-CTS-PBSG) – The doctoral degree in Integrative Life Sciences with the Psychiatric, Behavioral and Statistical Genetics concentration (ILS-PBSG) was designed by faculty at the Virginia Institute for Psychiatric and Behavioral Genetics. VIPBG is an interdisciplinary institute that brings together faculty with a wide range of scientific backgrounds ranging from statistical and molecular genetics to epidemiology, psychology, psychiatry, and neurosciences all with the joint focus of understanding how genetic and environmental factors impact the development of psychiatric and substance use disorders and behavioral outcomes. Faculty members work across genetic epidemiological, genomics, and molecular biology approaches and statistical methods development. Students in the ILS-PBSG track obtain interdisciplinary training with coursework in psychology/psychiatry, epidemiology, statistic and molecular genetics. Students can tailor their training and research experience to their particular career goals by selecting electives in their focused area of interest.
Training Program Objectives – The ILS-PBSG PhD program is intended to set the tone for a career and life-long learning in psychiatric, behavioral and statistical genetics by developing knowledge of the field and skills in critical thinking, study design, literature review, laboratory techniques, data collection, analysis, interpretation, and integration, and written and oral communication while fostering the student’s development as an independent researcher, laboratory director or teacher.
PhD Program – The PhD degree requires at least three years of study for students entering with a B.S. or B.A. degree. Students working toward the PhD degree in ILS-PBSG pass through two stages of graduate study. The first stage consists primarily of course work recommended by the PBSG program and the student’s Graduate Committee; the second of the development and execution of an original research leading to the doctoral dissertation. A PhD is awarded as the ultimate recognition of a student’s achievement of independent, creative and publishable research. Science requires a full time commitment and it should not be assumed that work of doctoral quality could be accomplished within the constraints of a 40 hour 9 to 5 workweek. Students are expected to develop their knowledge and critical skills within their chosen areas of inquiry to such a level that they are able to transcend the scholarship of any one of their advisers.
Admissions Criteria – All applicants must have earned a baccalaureate degree or its equivalent at the time of enrollment. Applicants holding an undergraduate degree from recognized foreign institutions must display an acceptable level of English proficiency by achieving a score of 100 on the TOEFL examination. Because the ILS-PBSG is an interdisciplinary training program we encourage students from a variety of backgrounds to apply. Our current trainees have undergraduate degrees in many different majors. There are no requirements with respect to undergraduate course content. Students with background in biology, genetics, statistics, psychology, or other relevant biological/social science and/or math courses are preferred. However, extensive background across all of these areas is not necessary. The training program curriculum is flexible to allow students to take heavier course content in areas in which they need additional training to achieve an interdisciplinary foundation. We place emphasis on finding students with strong academic records and interests that match the training goals and research areas of the Virginia Institute for Psychiatric and Behavioral Genetics.
Application Materials – All applicants must provide the following:
- Official transcripts of all prior undergraduate/graduate work. Applicants must have attained a minimum GPA of 3.0 in undergraduate study to be considered.
- A statement of purpose for application to the program. The document should be 1.5 or double-spaced with one-inch margins, in a font height no smaller than 11 points. The statement of purpose should cover the below issues in 2-5 pages:
- why the applicant wishes to pursue a PhD in the ILS-PBSG program
- background experience relevant to pursuing a PhD in the ILS-PBSG program
- research interests and potential faculty mentors
- description of the applicant’s career goals
- Three current letters of recommendation
- Scores from the Graduate Record Examination [GRE]. Applicants must score at the 75% percentile or above in all sections of the GRE
- International applicants must also provide, to the VCU Office of International Education: Scores from a Test of English as a Foreign Language [TOEFL] or an [IELTS]: International English Language Testing System
Application Process – Applications for graduate study in the area of ILS-PBSG can be obtained at the VCU Graduate School. Applications should be initiated online from the Graduate School admissions page. Under the “planned course of study” drop-down menu, please select: Clin & Trans Sci/Psych, Behav, & Stat Gen-PHD (Select Conc). Please note that there is no separate application for the ILS-PBSG program. Although there is not a hard deadline for admissions, applications received by January 10 will receive priority consideration. For additional information or questions, please contact Dr. Nathan Gillespie.
Funding – Typically, funding for the first two years comes from the Center for Integrative Life Sciences and the VCU Graduate School. Graduate students in the ILS-PBSG program are funded through a variety of sources, including University Graduate School Fellowships, NIH grants held by individual VIPBG faculty, and two VIPBG training grants. Funding includes tuition and a stipend. Graduate student stipends for the ILS-PBSG program generally meet or exceed NIH levels. Read more about Current NIH stipend levels.
