Some of the most consequential advances in healthcare begin long before they reach a patient, they begin with the ability to turn complex information into decisions that can make a meaningful difference.
For Dr. Ewa J. Kleczyk, PhD, that connection between data and better health outcomes has been a defining thread throughout her professional journey. From growing up in Wroclaw, Poland, and moving to the United States to pursue her education, to building a career at the intersection of economics, analytics, and healthcare, her path reflects a consistent belief: data creates its greatest value when it moves beyond observation and becomes actionable evidence.
Today, as Chief Data & Analytics Officer at Prolaio, Dr. Kleczyk is bringing that philosophy into cardiovascular digital health, leading the Data Science & Services organization and helping build the analytics infrastructure behind next-generation cardiac monitoring. Her approach is grounded not only in innovation, but also in scientific rigor, credibility, and the responsibility that comes with applying data and AI in regulated healthcare environments.
Her journey also offers a broader perspective on where healthcare analytics is heading, from data collection toward connected, operationalized intelligence capable of supporting better decisions and outcomes. In this conversation with The Euro Magazine, Dr. Kleczyk reflects on the experiences that shaped her career, the impact she hopes to create, the principles behind her leadership, and why precision, evidence, and investing in people remain essential as healthcare continues to evolve.
From Wroclaw to Healthcare Analytics
Dr. Ewa J. Kleczyk grew up in Wroclaw, Poland, and moved to the United States to pursue her education, a decision that shaped everything that followed. Her mother was a nurse in Poland, and that early exposure to healthcare, paired with her own fascination with economics and mathematics, planted the seed early.
She earned her bachelor’s degree in economics, with a minor in mathematics, at the University of Maine, followed by a master’s degree in resource economics and policy, and eventually a PhD in economics from Virginia Tech.
What inspired her was not a single moment, but the growing realization that data is not valuable in isolation. It only matters when it is operationalized into decisions that improve people’s lives. That realization drew her specifically to healthcare analytics: the opportunity to bridge rigorous data science with outcomes that actually matter to patients.
Building with Scientific Rigor
Today, Dr. Kleczyk serves as Chief Data & Analytics Officer at Prolaio, a cardiovascular digital health company that is a subsidiary of Kardigan. She leads the Data Science & Services organization, building the analytics infrastructure behind next-generation cardiac monitoring.
What sets the work apart, in her view, is the discipline behind it. The organization is not simply building algorithms, it is building them to withstand FDA scrutiny. Every digital biomarker developed goes through the same rigor as a regulated medical device because, as she explains, that is exactly what it is.
In an industry filled with bold AI claims, Dr. Kleczyk and her team are focused on generating evidence that stands up to scrutiny and delivers insights that go beyond just bold claims to real impact.
Turning Data into Meaningful Impact
Looking back over her career, what Dr. Kleczyk is most proud of is not any single project, but the throughline of impact on healthcare and drug development that connects all of it.
From her early work in pharmaceutical market research and real-world evidence, through building analytics organizations at her past organizations, to advancing digital biomarkers at her current organization, the common thread has always been turning complex data into evidence that actually changes how care is delivered or how a drug reaches the patients who need it.
If she had to define what all of that adds up to, it would be nearly two decades spent helping organizations move from viewing data as a support function to recognizing it as a strategic engine for better health outcomes. Watching that shift take hold, and seeing the teams she has built carry it forward on their own, is the achievement she would point to.
Closing the Gap Between Data and Outcomes
The next phase of Dr. Kleczyk’s journey is being driven by the same purpose that has guided her since the beginning of her career: closing the gap between data and better health outcomes, whether that means accelerating drug development or giving clinicians a fuller, more actionable picture of patient health.
She sees the next decade of healthcare analytics shifting from “data collection” toward operationalized intelligence, where data is not sitting on the side supporting decisions but driving them directly, in real time.
Her goal is to continue pushing in that direction by building connected systems and platforms rather than siloed capabilities, so that the impact on patients and drug development compounds rather than plateaus. It is a goal that has carried her across every role she has held, and it remains the one she is still pursuing.
Precision, Speed, and Credibility
In regulated health technology, Dr. Kleczyk believes the competitive edge is not speed for its own sake, but precision paired with speed.
She is careful never to overstate where the science is compared with where the organization wants it to be. For her, credibility compounds, and the stakes in healthcare are simply too high to cut corners.
She also relies on a combination of data-driven rigor and seasoned intuition. Certainty is a luxury in an industry moving this quickly, so learning to make high-stakes decisions without perfect information has become one of her most valuable skills.
Advice for the Next Generation
For aspiring professionals and entrepreneurs, Dr. Kleczyk’s first piece of advice is to understand what they are genuinely passionate about. Whether studying or working, she believes people need to love, or at least respect, what they do every day.
Second, she encourages professionals not to be afraid of a non-linear path. Some of the best analytics leaders she knows did not begin their careers in analytics.
Finally, she emphasizes investing in a team’s growth as deliberately as one invests in personal development. Leadership, in her view, does not require having every answer. It requires the willingness to step forward, ask the right questions, and make room for the people around you to take ownership as well.
Conclusion
For Dr. Ewa J. Kleczyk, PhD, the evolution of healthcare analytics is ultimately about more than collecting increasingly sophisticated data. It is about ensuring that information becomes useful, actionable, and capable of contributing to better decisions for patients, clinicians, and drug development.
Across nearly two decades of her career, that purpose has remained consistent even as her responsibilities and the technologies around her have evolved. From pharmaceutical market research and real-world evidence to building analytics organizations and now advancing digital biomarkers, she has continued to pursue the same fundamental goal: closing the distance between complex data and meaningful health outcomes.
As healthcare moves toward a future shaped increasingly by AI, connected systems, and real-time intelligence, Dr. Kleczyk’s perspective places equal importance on innovation and responsibility. Precision, scientific rigor, and credibility remain central to how she approaches progress, particularly in an environment where the consequences of overstating what technology can deliver are significant.
Her journey also reinforces an important dimension of leadership: lasting impact is not created by data or technology alone. It depends on people who are prepared to ask the right questions, make thoughtful decisions even when certainty is unavailable, and create space for others to grow and take ownership. For Dr. Kleczyk, the pursuit continues, not simply toward more advanced analytics, but toward a healthcare ecosystem where data can more directly and responsibly contribute to better outcomes.
