Medical Science Liaisons (MSLs) are highly trained healthcare professionals who serve as a bridge between pharmaceutical or biotechnology companies and the medical community. They play a vital role in educating healthcare providers, supporting research initiatives, and facilitating the exchange of scientific knowledge. Unlike sales representatives, MSLs focus on science and education rather than directly promoting products.

What Does a Medical Science Liaison Do?

The day-to-day responsibilities of an MSL can vary depending on the company, therapeutic area, and specific role, but here are some core duties:

• Building Relationships: MSLs establish and maintain relationships with Key Opinion Leaders (KOLs), who are experts in their respective fields. This involves regular communication, meetings, and attending conferences.
• Providing Education: They educate healthcare providers about the science behind products, treatments, or disease states, ensuring that the information shared is accurate, evidence-based, and unbiased.
• Supporting Clinical Trials: MSLs often play a role in supporting clinical research by identifying sites, engaging investigators, and acting as a liaison between the company and trial sites.
• Gathering Insights: They provide feedback to their company about trends in the medical community, including unmet needs, competitor activity, and KOL opinions.
• Internal Training: MSLs may also help train internal sales and marketing teams to ensure everyone has a clear and accurate understanding of the science behind the company’s products.
• Bridging the Gap: From my own personal experience, MSL’s were an important bridge between the field representatives, who are frequently very limited on what they can say, and the health care provider clients ,who may need more information than what the field representatives can legally say.

Skills Needed to Become an MSL

MSLs require a unique combination of skills, blending scientific expertise with excellent communication and relationship-building abilities.

• Scientific Expertise: A strong understanding of the therapeutic area they work in, and usually require an advanced degree such as a PharmD, MD, PhD, or RN/PA with specialized experience.
• Communication: The ability to explain complex scientific concepts clearly and effectively to different audiences, from healthcare providers to internal teams.
• Interpersonal Skills: Building relationships with KOLs and team members requires strong emotional intelligence and networking skills.
• Problem-Solving: MSLs must navigate challenges like addressing scientific misconceptions or resolving issues during clinical trials.

Pros and Cons of Being an MSL

Pros

• High Earning Potential: MSLs are among the highest-paid non-clinical roles, with salaries often ranging from $120,000 to $170,000 annually, depending on experience and location. As you obtain more experience and move higher in leadership, this number can climb to over $200,000. There are often other financial perks such as bonuses and stock option plans.
• Diverse Work Environment: No two days are alike, as MSLs balance field visits, conferences, and internal collaborations.
• Intellectual Stimulation: The role involves staying at the cutting edge of medical science, which can be rewarding for those who love learning.
• Flexibility: Many MSL positions offer remote work options, with travel being a significant part of the role.

Cons

• Demanding Schedule: MSLs may need to travel frequently, attend evening events, or manage tight deadlines. Many companies as well are global; emails and requests may come at odd times because the company is literally never closed.
• High Expectations: Companies expect MSLs to maintain deep scientific knowledge, requiring continuous education and preparation.
• Challenging Entry: Breaking into the field can be difficult without prior experience or a strong network, as most companies prefer candidates with advanced degrees and some industry exposure. There is also a lot of competition for these roles; persistence is going to be necessary in the search and application process.

How to Become a Medical Science Liaison

1. Educational Background: Most MSLs hold advanced degrees (PharmD, MD, PhD, or equivalent). However, nurse practitioners and physician assistants can also enter the field if they have expertise in the relevant therapeutic area.
2. Certification: A certification always makes your resume stand out. Consider getting your MSL-BC (board certification).
3. Gain Relevant Experience: Experience in clinical research, pharmaceuticals, or biotechnology is often required. Specialize if possible; I frequently see MSL positions in weight loss (especially with the introduction of GLP-1 class drugs), diabetes, hematology, oncology, and cardiology. Positions such as Clinical Research Coordinator or Field Application Specialist can also be stepping stones.
4. Network, Network, Network!: Attend industry conferences, talk to all of the sales reps who call on your area and ask them to forward your resume to their HR, and connect with MSLs on LinkedIn. Many companies reward employees with bonuses for referring qualified candidates to open positions; the people you network with WANT to help you. An internal referral will also increase your chances of interviews. There are even recruiters on LinkedIn who specialize in working only with filling MSL roles (I’m actually connected with one, so email me if you need their LinkedIn info).
5. Join the Society: the Medical Science Liaison Society has a plethora of recourses, networking opportunities, and events you can participate in to help stand out.
6. Develop Key Skills: Hone communication, presentation, and interpersonal skills, as these are critical for success in the role. You will probably have to develop and give a short presentation as part of your interview process; I’d recommend to do one relevant to the job you are applying for.
7. Apply Strategically: Tailor your resume to highlight relevant experience and skills, focusing on your ability to communicate complex scientific information and build relationships.
8. Internships: If you are are still in school, and this is a path you are especially interested in, look for internships within pharmaceutical companies. I have heard from other MSL’s that interns frequently get hired directly from this type of program, even over applicants with much more industrial and clinical experience.
9. Do not Limit Your Search to only Pharmaceutical Companies: Most of the time, you only hear of pharmaceutical companies hiring MSL’s. This is not true! Medical device companies such as BD and DNA companies such as Natera occasionally have MSL positions available, so be sure to look outside of pharma as well!

Is an MSL Role Right for You?

A Medical Science Liaison position can be an excellent fit for healthcare professionals who enjoy blending science, education, and networking in a dynamic environment. If you thrive on intellectual stimulation, don’t mind travel, and have a passion for advancing medical science, this could be the perfect career move for you.

Final Thoughts

Medical Science Liaisons play a crucial role in the pharmaceutical and biotechnology industries. By fostering collaboration and sharing knowledge, they contribute to advancements in healthcare that benefit patients worldwide. While the path to becoming an MSL can be competitive, the rewards—both personal and professional—are well worth the effort.
