Master of Science (MS) in Toxicology for Human Risk Assessment
The Master of Science in Toxicology for Human Risk Assessment is intended for students interested in toxicity testing and risk assessment. The degree emphasizes the integration of traditional in vivo models and emerging in vitro and in silico models into work by regulators and risk assessors. Graduates can play an essential role in the scientific evaluation of such toxicity testing information. Students completing the program will also fulfill the requirements to earn the Certificate in Risk Sciences and Public Policy.
The full-time program consists of nine months of coursework focused on the fundamental concepts and testing approaches used in classic risk assessment processes, as well as those used in the new paradigm for toxicity in the 21st Century, and an internship with a government agency, non-governmental organization, industry, or private sector group.
The curriculum consists of core courses that will be taken during the first year of the program, during the four 8-week terms from September to mid-May. The internship and a capstone essay will be completed in the second year.

Internship
Students in this professional degree program assume responsibility for a professional project to be carried out off-site at a governmental agency, non-governmental organization, industry, or private sector company. Students will work with the faculty adviser to identify internship opportunities. The minimum duration of the internship will be four months (two academic terms). The student will be directed in the internship experience by an on-site mentor and will regularly communicate with their academic adviser. The overall length of the project period may be extended beyond the minimum requirement.
For full-time students, the internship involves 32 course credits of 182.810 MS Field Placement. For part-time students, it involves 3 credits. The latter students should register for these classes on the following basis: 1 credit of 182.810 for preparation of the internship proposal and data collection; 1 credit of 182.850 to draft the essay; and 1 credit of 182.850 for finalizing the essay and formally presenting it at a seminar with faculty and fellow students. The registration timeline for these courses is decided between the student and their adviser.
Essay and Presentation
Students in professional programs at the Bloomberg School of Public Health must successfully submit a culminating project that demonstrates integration of the skills developed during the coursework and internship experiences. For students in the MS program, this project takes the form of an in-depth capstone essay.
The topic of the essay will be linked to the specific or general focus of the internship experience and will be chosen in consultation with the adviser, who must approve it. Ideally, students select a topic that will lend itself to publication in a scientific journal. Following approval of the essay, students must make a formal oral presentation to the Department.

CODE OF CONDUCT
The fundamental purpose of the Johns Hopkins University’s (the “University” or “JHU”) regulation of student conduct is to promote and to protect the health, safety, welfare, property, and rights of all members of the University community as well as to promote the orderly operation of the University and to safeguard its property and facilities. As members of the University community, students accept certain responsibilities which support the educational mission and create an environment in which all students are afforded the same opportunity to succeed academically.
Allegations of sexual misconduct are covered by JHU’s Sexual Misconduct Policy and Procedures for faculty, staff, and students. The University encourages individuals to report incidents of sexual misconduct and provides a variety of avenues, both formal and informal, by which individuals can report complaints of sexual harassment. Allegations of sexual harassment by students are covered under the JHU program and under the Student Conduct Code.
Personal Relationships
The Johns Hopkins University is committed to the personal, academic, and professional well- being and development of its students, trainees, faculty, staff, postdoctoral fellows, clinical residents, and all other members of the University community. The University seeks to maintain an atmosphere of mutual respect, collegiality, fairness, and trust. The Personal Relationships Policy implements the University’s commitment to maintaining the integrity of its educational and working environment. This policy focuses on the conflict of interest that may exist when individuals simultaneously engage in both personal and professional relationships in which one individual has the potential to exert substantial academic or professional influence over the other.

Human Subjects
The Johns Hopkins University is committed to protecting the rights and welfare of all individuals participating as subjects in research. To meet this obligation, the Bloomberg School has two on- site Institutional Review Boards and an external IRB (the Western IRB) that review studies on the School’s behalf. All faculty and students who are involved in human subject research must meet the compliance training requirements of the Bloomberg School IRB. It is the responsibility of students and faculty to make certain that approval is obtained from the IRB before beginning any research involving human subjects. The IRB is also responsible for determining whether certain research activities qualify for exempt status under the regulations and institution policy.
For IRB announcements and updates, and for additional information and requirements on conducting human research, please contact either the:
- Bloomberg School’s IRB Office, Room E1100, Wolfe Street Building (410-955-3193); email at jhsph.irboffice@jhu.edu, or Homewood IRB Office
- Homewood IRB Office (410-516-4820); email at levans22@jhu.edu; https://homewoodirb.jhu.edu/ participants/
Animal Research
The Johns Hopkins University is committed to protecting the rights and welfare of animals used in research. All students involved in animal research must first complete an online training module, Animal Care and Use, available through myLearning in the JHU Portal, before beginning work with animals. Additional training may also be required. Students must also be listed as student investigators on projects they are working on that involve animals.
The care and use of animal subjects are regulated by the Animal Welfare Act, which is implemented by the U.S. Department of Agriculture. The University has one assurance with the federal government (the Office of Laboratory Animal Welfare [OLAW]) and, therefore, the University has one animal care and use committee (IACUC). Faculty from the Bloomberg School, the School of Medicine, and the Homewood campus serve on this committee. An approved protocol MUST be obtained before animals can be purchased. Questions regarding submission of animal research protocols should be addressed to the IACUC Office at 443-287- 3738. Animal care and procurement are under the purview of Johns Hopkins Research Animal Resources.
For those exposed to animals either directly or indirectly, their bedding, waste products, fresh animal tissues, or equipment involved in animal use and care, Johns Hopkins requires the following to reduce health risks associated with animal exposures. Students may view the full animal research policy here.
ETHICS POLICIES
All members of the Johns Hopkins community are responsible for immediately informing the Academic Ethics Board of the Bloomberg School of Public Health of any suspected violations of its Constitution. The Ethics Board, composed of six students and four faculty members, is responsible for implementing its Constitution according to the procedures set forth therein. This includes formal hearings of suspected violations.
Allegations of fraud in research by students will be handled and resolved according to the policies and procedures specified in Faculty PPM 7 – Research Misconduct. Penalties for students who are found responsible for engaging in fraud in research under Faculty PPM 7 may be selected from among the penalties specified in the Student Academic Ethics Code (Student PPM 1) as appropriate.
Allegations of violations of academic integrity by students in the School are covered under the policies and procedures contained in PPM for Students - 1 (Academic Ethics) and the School’s Academic Ethics Code. Allegations of unsatisfactory performance or unacceptable behavior by faculty are covered by PPM Faculty - 8 (Procedure for Handling Allegations of Unsatisfactory Performance or Unacceptable Behavior), and allegations of fraud or misconduct during the conduct of research by faculty are covered by PPM Faculty - 7 (Fraud in Research).
Allegations of misconduct by staff are covered by policies and procedures established by the University Office of Human Resources as stated in the Personnel Policy Manual. (This information is taken from the School’s POLICY AND PROCEDURE MEMORANDUM STUDENTS – 1, SUBJECT: Academic Ethics).
LEAVE OF ABSENCE
If it becomes necessary to take a break from studies, students should contact their adviser and academic program manager to determine if a formal leave of absence (LOA) is necessary. Any request for change of status must be discussed with the program or track director(s) and academic program manager and approved by the department and school. For more information, please see the University Policy.
parental accommodations

TRAVEL RESOURCES
While BSPH encourages participation in opportunities to supplement your education or research in other countries, international tensions can be high and the resources on the U.S. International Travel website may assist you in making an informed decision.
Students are not obligated to travel internationally, and each student has the right to decline to travel abroad. If the student is supported by a research project that requires such travel and the student chooses not to travel, the student may be removed from that project following discussions with the principal investigator and the EHE program or track directors.
Graduate students who decide to travel abroad must demonstrate that they understand and voluntarily accept the risks inherent in international travel. To do so, students must first receive the appropriate departmental approvals for the trip through their adviser and program or track director(s). Students should also evaluate options for registering travel and obtaining pre-travel immunizations through the school or health care system.
Immunizations
If you are traveling to a less-developed part of the world, you should be certain to contact your health care provider or the Johns Hopkins International Travel clinic to learn about recommended immunizations and other matters to guard your health. Located on the East Baltimore campus, you can reach the International Travel Clinic by telephone at 410-955-8931.
Stay Informed
Students are encouraged to vigilantly monitor consular and press reports regarding the country (or countries) where they plan to travel. Students may also check the consular reports of countries friendly to the U.S. (e.g. Australia, Canada, United Kingdom) as well as reports from other international agencies (e.g. United Nations). Students should participate in the security briefings offered by other organizations with whom they may be working.
Maintain Communication
When traveling in an area where regular communication is difficult, students are encouraged to maintain contact with their advisor and/or the academic program manager.
State Department Registration
For students who are likely to stay for a prolonged period in a high-risk area of the world, registration at the U.S. embassy or consulate is essential.
International Students
OIS may be contacted at 410-955-3371. International students must contact the Office of International Services (OIS) well in advance of any travel to avoid compliance issues with their visa status.
