Curriculum
The online Master of Science in Health Sciences (MSHS) in Clinical Microbiology is a 36-credit-hour program that provides students with medical microbiology and laboratory science coursework as well as a hands-on general microbiology practicum. Students will also explore related fields of study, including clinical pathology, bacteriology, infectious diseases, and virology.
Six credit hours of elective courses are selected in consultation with the program director from existing online graduate courses in Biomedical Laboratory or Health Sciences.
Program Outcomes
The online Master’s in Clinical Microbiology program leverages distinguished faculty, innovative curriculum, and real-world experience. Upon completion, you’ll gain the comprehensive skills needed to succeed in the medical microbiology field and be able to:
- Interpret patient laboratory results to aid in the diagnosis of infectious disease.
- Assess laboratory methods used to identify infectious agents in the clinical microbiology lab.
- Analyze general and specific mechanisms by which an infectious agent causes disease.
- Assess strategies to treat infectious diseases, including the appropriate use of antimicrobial agents and common mechanisms of antimicrobial action and resistance.
- Adhere to all local, state and federal laboratory regulations to maintain a safe and ethical work environment
Who Is the Ideal Student for This Program?
The MSHS in Clinical Microbiology program is designed for individuals who have a baccalaureate degree and want to obtain employment in clinical or public health microbiology laboratories. Many diagnostic laboratories require employees to be certified and this program will provide the theoretical knowledge, laboratory skill, and ability to sit for a national board of certification examination in microbiology. The ideal candidate for this program is someone that enjoys science and hands-on laboratory work, is detail-oriented, able to multi-task, and someone that likes to solve puzzles.
What Can You Do After Graduation?
The program curriculum provides eligibility for the ASCP Technologist in Microbiology exam, a gold standard in global certification for medical laboratory professionals. This will provide you with the skills needed to compete for the medical microbiology career you want.
Career Outlook
There is a growing need for professionals in medical microbiology. The Bureau of Labor Statistics predicts that the number of available health care jobs will increase through 2030, creating more than two million new positions for medical professionals.1 With this projected growth, now is the perfect time for students to build careers in medical microbiology, clinical pathology, bacteriology, virology, and infectious diseases with the MSHS in Clinical Microbiology program at GW.
Graduates of this program will have the qualifying skills needed for employment in a variety of general microbiology settings, including diagnostic microbiology laboratories, research institutions, public health laboratories, biotechnology firms, pharmaceutical companies, or governmental agencies. Careers in clinical microbiology include:
- Microbiology technologist
- Public health microbiologist
- Microbiology laboratory supervisor
- Research Assistant/Associate
- MLT/MLS instructor
New York residents – We advise applicants considering New York state licensure to review license requirements before accepting admission to the program.
State Licensure
Completion of this program will make graduates eligible to register for an ASCP Board of Certification Exam. However, this does not automatically guarantee a graduate will also meet their state’s licensure requirements (if applicable). States may have specific licensure requirements and each student is encouraged to contact their state’s regulating agency to review these requirements prior to beginning any degree program. State’s requiring licensure may require an extended duration of practicum experiences, additional academic courses (outside the student’s program of study), etc. These additional requirements may require you to take a course or courses outside of GW. In particular, New York and California typically have additional requirements for state licensure. Please also be aware that the state of NY does not provide licensure to individuals that are certified in one subject, hence, this program will not provide eligibility to obtain a NY state license. Students who live in New York or California or plan to relocate to New York or California are recommended to research the NY and CA licensure requirements.
