Medical Science Liaison

Medical science liaisons (MSLs) can have various job titles as clinical science liaisons, medical liaisons, medical science managers, regional medical directors, and regional medical scientists. As you may have guessed from the name, a medical science liaison serves as a bridge between leading researchers, clinicians, physicians, and companies. They work as scientific resources and experts, advising their clients on scientific matters, treatments, and relaying scientific data.

Medical science liaisons generally specialize in areas such as biotechnology, pharmaceuticals, medical devices, and other healthcare-related fields. They can concentrate on a specific disease state or therapeutic areas such as cardiology, oncology, gastroenterology, rheumatology, and infectious diseases.

While MSLs may regularly have to work with marketing and sales teams, it must be noted that their role is not that of a salesperson. Instead, they act as a knowledgeable link between product development and the healthcare industry at large. They are clinical researchers who bring the latest knowledge and research of therapeutic specialties to the people developing therapeutic products.

The nature of an MSL role is such that professionals can expect extensive travelling to meet clients and also to attend industry conferences. The role involves spending time in meetings and delivering complex data in an easy to understand manner. Thus, medical science liaisons must also have excellent interpersonal, analytical, communication, and organizational skills.

Medical Science Liaison Specializations & Degree Types

In order to become a medical science liaison, one generally needs to have a doctorate in life sciences with a focus on human health or medicine, as this is the minimum employers require. Some of the common degrees aspirants can pursue include that of a medical doctorate (MD), a doctorate of philosophy (PhD), or a doctor of pharmacy (PharmD). Some MSLs have registered nurse (RN) or master of science in nursing (MSN) degrees and acquire years of experience in a particular therapeutic field such as pain management, metabolism, cardiovascular, and oncology.

Irrespective of a candidate’s area of concentration, employers do seek professionals who have taken courses in epidemiology and pharmacy. Additionally, because MSLs often interact with regulatory agencies, prospective candidates should also consider taking classes in health economics or health policy. Finally, since the job involves a great deal of communication, a course in public speaking would also be helpful.

Medical Liaison Degree Program Admissions Requirements

According to the Medical Science Liaison Institute, an advanced degree, such as a PharmD, MD, or PhD in a research science, is the minimum requirement to begin a career in the field. (Please note, however, that the minimum educational requirement for the Medical Science Liaison Society—the MSL-BC—is a bachelor’s degree and qualifying work experience.)

Since MSLs act as consultants for biotechnology and pharmaceutical companies, the candidates must also have interpersonal skills, including the ability to create and to sustain relationships with industry leaders. Candidates must also be skilled at research.

The common admission requirements for degrees such as PhD, MD or PharmD are as follows :

  • A bachelor’s degree is required for all program applicants, and a master’s degree may be required for selected programs
  • Minimum undergraduate grade point average of 3.0
  • GRE (Graduate Record Examination) scores are often required for admittance into PhD programs in the US
  • Students who are from a country where English is not the official language, will have to take the TOEFL (Test of English as Foreign Language) or IELTS (International English Language Testing System)
  • Letters of recommendation from professors or higher education administrators will improve the chances of getting accepted.
  • Official transcripts from all institutions attended
  • A writing sample

While the above constitute general admission requirements for these programs, students must note that each university may also have some other special requirements. In order to increase their chances of getting accepted into a program, students must carefully review each program’s admission requirements.

Medical Liaison Program Accreditation

Before taking up a doctorate or PharmD program, students must look out for programmatic or regional accreditation. Accreditation is a process by which universities are reviewed to ensure that they provide quality education. For students and employers, graduating from an accredited university is a mark of trust and assurance.

Those aspiring to pursue a career as a medical science liaison should look out for accreditation from the following bodies:

  • The American Council on Pharmaceutical Education (ACPE) provides accreditation to doctor of pharmacy degrees to ensure that they meet educational qualifications.
  • The Commission on Collegiate Nursing Education (CCNE) is an accrediting body that has been recognized by the US Secretary of Education as an accrediting body at the national level.

Please note that regardless of the type of degree chosen, prospective medical science professionals are encouraged to ensure that their institution of choice is accredited by a body recognized by the Commission for Higher Education Accreditation (CHEA).
