Setting your sights on becoming a Medical Science Liaison (MSL) is an exciting career path! 

MSLs hold some of the most impactful roles in the life sciences, spanning across pharmaceutical, biotechnology, diagnostics, and medical device industries. If you’re passionate about science and love the idea of collaborating with healthcare experts to improve patient outcomes, this could be your dream role.

So, You Want to Be a Medical Science Liaison? Here’s How to Make it Happen!

What Exactly Does an MSL Do?

As an MSL, your main role is to communicate complex scientific information in a clear, accessible way. Think of yourself as a scientific advisor. You’ll be building relationships with key opinion leaders (KOLs), educating healthcare providers, and helping advance medical innovations. Your expertise and insights guide healthcare providers, improve patient outcomes, and drive the adoption of new treatments or technologies. MSLs bring scientific expertise to every conversation. (If you want to master this skill early, our Presentation Mastery Course is a great next step.)

Requirements to Enter the MSL World

This is a competitive field, and most MSL roles require an advanced scientific degree (PA, NP, Ph.D., PharmD, MS, or MD). Companies are looking for people who can communicate complex data clearly and have an in-depth understanding of their therapeutic area. If you’re coming from a research or clinical background, it’s helpful to start getting familiar with industry dynamics and preparing to translate your skills into an MSL’s world.
