Albert Bourla – Chairman & Chief Executive Officer, Pfizer
Albert Bourla grew up in Thessaloniki, Greece, the son of Sephardic Jewish parents who survived the Holocaust.
After earning a doctorate in veterinary medicine from the Aristotle University of Thessaloniki, he joined Pfizer Inc. in 1993, eventually becoming CEO on January 1, 2019.
Who Should Follow Albert Bourla?
- Professionals interested in leadership stories from global‑Greek executives.
- Individuals curious about the pharma industry and how large organizations respond in times of crisis.
- Anyone interested in the human side of business leadership and resilience.
About Pfizer Inc.
Pfizer is a global pharmaceutical company that developed the joint COVID‑19 vaccine with BioNTech under Bourla’s leadership.
In 2020, Bourla personally emphasised that “financial returns should not drive any decisions” in that vaccine work.
LinkedIn Content Strategy
On LinkedIn, Bourla shares reflections that link personal history (his Greek roots, his family’s survival) with corporate purpose.
He posts updates when major milestones in vaccine development or company strategy occur, and uses narrative elements (his early life, his journey at Pfizer) to give a human dimension to what would otherwise be an exclusively corporate story.
What Makes Albert Bourla Different?
Bourla stands out because he bridges his Greek heritage and global leadership in one of the world’s largest pharma companies.
His story is not purely corporate. It includes deep personal roots and survival. He chose to highlight his family’s background in public speeches, reinforcing authenticity.
Additionally, he navigated Pfizer through one of its most significant challenges (COVID‑19 vaccine development) under intense public scrutiny.
Key Takeaways for Your LinkedIn Strategy
- Share personal narrative as a way to build relatability.
- Combine industry leadership content with human background to deepen engagement.
- Use milestone‑driven posts to mark big company events, framed through your own lens.
- Be transparent about your journey — let people see the full arc.
Where Albert Bourla Can Grow (On LinkedIn)
Bourla could increase interactive engagement by posting more posts that invite questions or commentary (for example: “Here’s what kept me up last night…”).
He might also diversify content formats — e.g., short videos discussing leadership lessons from his veterinary background — to make his messaging more accessible to non‑pharma audiences.
Athina Kanioura – Chief Strategy & Transformation Officer, PepsiCo
Athina Kanioura started her career in analytics and academia in the UK after studying for a PhD in Econometrics and Quantitative Economics at the University of Sheffield.

She posts about emerging business models, retail/consumers, and how large organisations can change. Her focus on storytelling about the stages of her own career gives her posts depth.
What Makes Athina Kanioura Different?
Unlike many C‑level executives, Kanioura transitions from technical academia (PhD) into the boardroom.
Her expertise in analytics and applied intelligence adds credibility in an environment where strategy often gets vague.
Her role spans beyond classic “strategy” — she covers platforms, data, talent and markets. She also represents a woman from Greece in a globally visible role — offering representation and inspiration.
Key Takeaways for Your LinkedIn Strategy
- Show a progression in your story — how you got from one place to another.
- Highlight one specialised domain (e.g., analytics) and show how it informs broader leadership.
- Use LinkedIn posts to discuss macro themes (data, talent, platforms) while grounding them in personal narrative.
- Represent your identity (geographic, cultural, educational) as part of your executive brand.
Where Athina Kanioura Can Grow (On LinkedIn)
Kanioura could deepen engagement by sharing more behind‑the‑scenes reflections of transformation work (challenges, not just successes).
She might also publish short video formats or LinkedIn Live sessions where she engages directly with younger professionals in analytics or strategy.
