Healthcare and biotechnology are evolving at lightning speed, driven by breakthroughs in genomics, immunotherapies, and personalised medicine. Pharmaceutical and biotech companies need professionals who can interpret the science behind these innovations and convey it effectively to clinical experts, key opinion leaders (KOLs), and internal stakeholders. That’s where the Medical Science Liaison comes in.
There are several reasons why MSL roles are booming:
Complexity of Modern Therapies: New treatments often involve advanced scientific principles—such as monoclonal antibodies, CAR-T therapies, and gene editing. Specialists with in-depth knowledge can help clinicians and scientists understand these products better.
Regulatory and Compliance Drivers: As regulations become stricter (for example, the updated ABPI Code in the UK), the need for scientific and compliant communication between the industry and healthcare professionals grows. MSLs bridge this gap with evidence-based discussions.
Expanding Therapeutic Areas: Beyond traditional areas like oncology and cardiovascular medicine, biotech companies are delving into niche segments—such as rare diseases and neurological conditions—where an MSL’s focused expertise is particularly valuable.
Increased Market Competition: Pharmaceutical organisations often have multiple treatments for the same condition competing in the market. Having a well-informed MSL team can differentiate a company’s product by offering scientific value and robust clinical data interpretation.
Strategic Influence: MSLs are key players in shaping how new therapies are positioned, understood, and eventually adopted. Their insights from the field help guide research, commercial strategy, and future product pipelines.
With healthcare’s growing complexity, it’s no surprise that Medical Science Liaison jobs have become increasingly crucial—and plentiful—throughout the UK.
2. What Does a Medical Science Liaison Do?
Despite the job title being well-known within pharma and biotech circles, many people outside these industries have limited awareness of what an MSL truly does. In essence, a Medical Science Liaison acts as the scientific ambassador for their organisation, ensuring transparent, evidence-based communication between the company and external medical stakeholders.
Specific responsibilities can vary based on the organisation’s size, therapeutic focus, and product pipeline, but typically include:
KOL Engagement: Building and maintaining relationships with Key Opinion Leaders—experienced clinicians, researchers, and healthcare professionals in a specific therapeutic area. MSLs share data, gather feedback, and collaborate on research or educational initiatives.
Scientific Presentations: Conducting scientific discussions, workshops, and presentations for healthcare professionals, internal teams, and at conferences. The aim is to provide up-to-date and accurate information about clinical trials, product safety, and efficacy.
Medical Education and Training: Helping to design training materials and educational programmes for healthcare providers, ensuring that patient care benefits from the latest scientific evidence.
Clinical Support: Assisting with clinical trials by identifying potential sites, supporting investigators, and ensuring trial data is accurately understood and communicated.
Gathering Field Insights: Providing internal teams (such as product development, marketing, and R&D) with real-world insights from clinicians and patients, thereby influencing the direction of future research and product improvements.
Advisory Boards and Meetings: Organising and participating in advisory boards, where medical experts discuss new therapies, unmet clinical needs, and upcoming research directions.

Biotechnology evolves rapidly—new discoveries, regulatory changes, and emerging competitors can transform the landscape overnight. A successful MSL remains flexible and engaged in continual professional development.
4. MSL vs. Other Pharmaceutical Roles: Understanding the Difference
The pharmaceutical industry features a variety of jobs—ranging from sales representatives and clinical research associates to regulatory affairs specialists. So, how does a Medical Science Liaison stand apart?
Non-Promotional Role: Unlike sales representatives, MSLs primarily focus on scientific exchange rather than direct product promotion. They adhere to compliance guidelines to ensure ethical engagement with healthcare professionals.
Clinical and Research Depth: While commercial teams may discuss a drug’s benefits, MSLs delve into the clinical evidence, trial design, and real-world outcomes. Their conversations are driven by scientific data rather than sales targets.
Focus on Relationship-Building: MSLs often have long-term relationships with KOLs, collaborating on research studies, advisory boards, and patient education initiatives. This contrasts with more transactional interactions typical of some commercial roles.
External Orientation: Despite being employed by a pharma or biotech firm, MSLs spend much of their time “in the field,” meeting with clinicians, researchers, and academic institutions. Their insights feed back into the company’s strategy and product evolution.
Bridge Between R&D and the Market: MSLs relay the latest scientific findings to external experts while also capturing feedback from the field. This two-way channel is vital for refining clinical trials, supporting pipeline decisions, and post-marketing surveillance.
