External Experts

External experts are scientific and medical professionals that life science companies engage for a variety of collaborative efforts, including working as advisory board members, investigators, or speakers at conferences.

Traditionally, experts have been referred to as “opinion leaders”, or “key opinion leaders” (KOLs) and while some experts are indeed key opinion leaders, the broader and more encompassing term (external) expert more accurately describes their role in general.

Categories of experts

External experts set themselves apart from their peers by standing out in one or several categories, e.g. by actively publishing in high-impact journals, frequent speaking engagements at conferences, or membership on advisory boards, editorial boards or medical society boards, or committees. Other categories are type and amount of funding, clinical trials they are involved in or affiliation with a highly regarded institution.

More recently, digital influencers who engage via online and social media, e.g. Twitter, LinkedIn, YouTube, have emerged alongside the more traditional external experts.

Traditional external experts are typically categorized as national, regional and local depending on their sphere of influence.

  • National and sometimes international experts are well-known in their therapeutic area and have earned accolades. These experts provide thought leadership, sit on advisory boards where they inform business matters ranging from clinical and medical to commercial issues, speak at highly relevant conferences and are well networked and highly regarded by other healthcare providers.
  • Regional experts often represent a more targeted level of influence in key geographic areas to address localized issues. Regional experts often have extensive experience in treating patients. They get involved in the pre- and post-launch phases to educate their peers based on their, e.g. in the context of symposia, webinars, CME or other regional/local focused events.
  • Local experts are HCPS with a community network of peers that trust them and reach out to them for advice. These experts are important because they have a peer leadership role that creates an adoption pattern among local communities and physicians.

Identifying external experts

Identifying the appropriate external experts is critical for medical affairs as well as their colleagues on the commercial side. While relying on existing contacts, networks and referrals can be used to identify top international or national experts, finding specialized expertise or HCPs with regional or local influence is difficult using these networks and can lead to biased lists.


A data-driven process that draws on a database that contains millions of detailed profiles of medical and scientific experts makes the process of finding the specialized knowledge and experience easy, fast and avoids bias.
