Bachelor's/MHS

The Bachelor's/MHS degree in Epidemiology is designed for undergraduate students pursuing a BA at Johns Hopkins University Krieger School of Arts and Sciences, majoring in Public Health Studies, and interested in pursuing an advanced Epidemiology degree at BSPH. The program prepares students for further graduate work or prominent careers in research and public health. One benefit of the Bachelor's/MHS is that it allows Johns Hopkins University undergraduates to take BSPH courses during their undergraduate program and apply up to 16 credits accumulated as undergraduates into the MHS program. In addition, students will have the opportunity to network with BSPH faculty to consider research and other engagement opportunities at BSPH during their undergraduate and MHS program.

Degree Program Requirements

Non-Course Requirements 

Residency 

A minimum of 64 credits is required to complete the MHS degree program. The residency requirement is four consecutive terms of at least 16 credits each. Residency must be completed during the program. 

Quarterly Master's Meetings

The Program Directors host quarterly meetings with all master's students. These meetings provide a forum to learn about academic policies and deadlines, raise questions and concerns, and to connect. All students are expected to attend.

Core Coursework 

The MHS degree is comprised of 64 credits minimum as follows: Students in the Analytic Path will complete 40 required credits and students in the Applied Path will complete 39 required credits (detailed in Table below). In addition, students will select a minimum of 12 credits (3-4 courses) within the list of approved Primary Electives (see list below). These Primary Electives will allow students to develop focused skills/expertise in topical or methodological areas within Epidemiology.  

Students will then take an additional 12 credits (Analytic Path) or 13 credits (Applied Path) of General Electives, which may be within or outside of the field of Epidemiology. Students will select Primary and General Elective courses in consultation with the director of their path. 

Cells to Society Courses (CEPH Requirements)

To address breadth, the National accreditor for schools of public health, Council on Education for Public Health (CEPH), has twelve “Introductory Public Health Knowledge Learning Objectives” in which all students must complete didactic coursework, and the “Cells-to-Society” courses to help programs meet this requirement.

For Epidemiology degree programs, five of the twelve competencies are covered through required Epidemiology Core Coursework. All students need to complete the eight indicated Cells-to-Society Courses by the end of their first year. 

View a full list of Cells-to-Society courses and term offerings. Epidemiology degree students are required to complete these 8 of the 12 sessions. Each course is 0.5 credits and is offered only online. Many of these courses can be used as introductions to full-term courses offered in multiple modalities throughout the year.

Culminating Experience 

MHS Analytic Path

In this project based course, students will create a scholarly product that generates new knowledge or synthesizes/integrates existing knowledge. Students will select from several datasets that will be made available for this course. Students will learn and apply the research process, including formulating a research question, selecting an appropriate analytical method and covariates, conducting the data analysis, and writing a scholarly research paper. 

MHS Applied Path 

In this project based course, students will create scholarly products that synthesizes/integrates existing knowledge important for improving public health and health equity. Students will use a real-world data set to create a series of products aimed for different target audiences. These will include products such as Situation Analysis, a Fact Sheet, and a Data Dashboard. Students will learn how to analyze real-world data and disseminate the information to a variety of key stakeholder audiences.

The Policy and Procedures Manual for the Master of Health Science

The Department of Epidemiology reserves the right to augment the PPM for BSPH. 

Academic Advising 

The Program Directors serve as advisors to MHS students. The Program Directors serve as Academic Advisors and meet with a group of advisees regularly to discuss academic issues, progress, development, and goals in the degree program. As part of their advising support, students will meet regularly with the Academic Program Manager and the Epidemiology Academic Core staff. 

Advisor/Advisee Manual 

Each student in the Department will engage in several advisee roles throughout their program, whether it be as a Teaching Assistant, Graduate Research Assistant, or academic advisee. In accepting any of these roles, the student agrees to abide by the University's Student Conduct Code. Faculty, fellows, staff, and students of the School assume a shared obligation to conduct themselves in a manner appropriate to the University's mission as an institution of higher education. The School’s Policy and Procedures Memorandum (PPM) for student academic ethics is available on SharePoint. Any mentor/mentee role assumes maintaining the academic integrity of the institution and preserving an environment conducive to the safe pursuit of the School's educational, research, and professional practice missions. Advisor(s) have the responsibility of serving as a guide and mentor. This manual is intended to guide the student and the faculty member(s) in making the Advisor/advisee relationship as successful as possible by:

• Answering questions that students frequently ask
• Providing guidance on how the student and Advisor can interact most effectively

Responsibilities of Advisors include:

• Provide oversight of the student’s progress by:
  • Providing a plan, overview, and goals for the role

Transferring Degree Programs

The Department of Epidemiology evaluates each applicant holistically for the degree program to which they applied. The degree programs are designed towards mastery of particular skill sets as preparation for specific career goals. Therefore, the expectation is that students will remain in the program to which they applied. In specific circumstances (outlined below), the Department leadership may consider a request for transfer on a case-by-case basis.

Transferring from the MHS Applied Path to the MHS Analytic Path 

Students in the MHS Applied Path are eligible to transfer to the MHS Analytic Path only if they have taken Epi 751 AND Epi 752. Applications must be made before the end of the add period of 3rd term. Students must then enroll in Epi 753 in 3rd term and then the MHS Analytic Culminating Experience in the 4th term. Applications must be approved by the Master's Program Directors and the Admissions and Credentials (A&C) Committee.

Academic Research & Ethics

All students must enroll in PH.550.860 Academic & Research Ethics during the 1^st Term of program enrollment at BSPH. The Avoiding Plagiarism at JHU training (developed by JHU Sheridan Libraries) course material is contained within the PH.550.860 Academic & Research Ethics at BSPH. This is a self-paced online module and must be completed within the 1^st Term of enrollment.

In the course, students are asked to upload two certificates to a CoursePlus DropBox showing completion of both parts of this course:

• Certificate from JHU for the Avoiding Plagiarism module
• Certificate from BSPH for completion of the Responsible Conduct of Research module

Students must also send an electronic copy of the certificates to the Academic Core (BSPH.EpiAcademic@jhu.edu) with their name and “Academic & Research Ethics Requirement” in the subject line of the email. 

According to the requirements of the Council on Education for Public Health (CEPH), all BSPH degree students must be grounded in foundational public health knowledge. Please view the list of specific CEPH requirements by degree type.

Educational Objectives

• Gain foundational knowledge in public health. 
• Gain an understanding of what epidemiology is, how it is used in public health, and the methods used to describe and evaluate variability in health states. 
• Use epidemiologic methods to assess health states and interpret findings for public health research, policy, or practice.
