Medical Science Liaison

Medical science liaisons (MSLs) can have various job titles such 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 traveling 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 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. If a professional has extensive experience in medicine, a healthcare-related MBA can also be a choice to enter this field.

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.
