What Is a Medical Science Liaison?
A Medical Science Liaison is a field-based medical professional who develops peer-to-peer scientific relationships with healthcare professionals, researchers and Key Opinion Leaders (KOLs). MSLs are scientific experts who work across the product lifecycle and primarily build and maintain peer relationships with leading physicians and academic experts.
In practical terms, you might spend one part of your week discussing clinical evidence with a specialist, another reviewing new publications and another sharing field insights with your internal medical team.
An MSL is not a conventional sales representative. The role is centred on scientific exchange, evidence and medical insight rather than sales targets.

Medical Affairs vs Medical Science Liaison: Are They the Same?
This distinction matters when you start searching for MSL jobs.
Medical Affairs | Medical Science Liaison |
A broader business function within life sciences | A specific role within Medical Affairs |
Covers multiple activities across the product lifecycle | Primarily focused on external scientific engagement |
May include medical strategy, publications, evidence generation and field medical | Builds scientific relationships with KOLs and HCPs |
Can include office-based and strategic positions | Usually involves substantial field activity and travel |
Includes several career paths | Can lead to Senior MSL, Medical Advisor and Medical Affairs leadership |
The MSL Society also identifies MSLs across pharmaceutical, biotechnology, medical-device, CRO and other healthcare organisations.
What Does an MSL Actually Do?
Your core responsibilities can include:
Building and maintaining relationships with KOLs and healthcare professionals.
Discussing clinical studies, publications and scientific evidence.
Responding to unsolicited scientific questions.
Identifying and communicating relevant field insights.
Supporting advisory boards, congresses and scientific meetings.
Collaborating with clinical development, regulatory, medical communications and other internal teams.
Reviewing emerging literature and developments within your therapeutic area.
Supporting scientific education and presentations.
Maintaining accurate documentation of field interactions.
Staying compliant with company policies and applicable regulations.
The role can therefore connect directly with the wider drug-development ecosystem. India's CDSCO continues to regulate clinical trials, and new-drug approvals under the New Drugs and Clinical Trials Rules, while its current regulatory framework includes ongoing clinical-research and ethics oversight.
How Much Travel Does an MSL Do?
This is one part of the job that you should know before applying.
MSLs are commonly field-based. Your territory could require visits to hospitals, academic institutions, clinics and conferences. Some interactions can happen virtually, but the job is not necessarily a nine-to-five desk role.
So, if you enjoy meeting people and having scientific conversations, travel can be an advantage.

Why is the need for Medical Science Liaison jobs increasing?
According to the Economic Survey 2025–26, India’s pharma sector is transitioning from a volume-driven model to one that emphasizes complex generics, biosimilars and innovation.
At the same time, there's continued expansion in India's pharmaceutical market and investment in biopharma, R&D and clinical infrastructure.
That creates a stronger need for professionals who can understand scientific evidence and communicate it responsibly to medical stakeholders.
