    How Kiran Veernapu Is Using AI to Turn Enterprise Data Into Better Patient Outcomes

    Kiran Veernapu has spent more than 25 years building the data systems that large organizations rely on to make decisions. His work spans healthcare, aviation, manufacturing, and enterprise technology, but the underlying challenge remains constant: turning scattered, inconsistent information into actionable insights.

    Starting in data architecture and business intelligence, Veernapu designed the warehouses and pipelines that move information through organizations. As machine learning matured, his focus shifted toward predictive analytics and clinical decision support—where the stakes are higher because a wrong answer at the point of care costs more than a wrong quarterly report.

    Much of his recent work centers on Clinical Decision Support Systems (CDSS), which sit between complex medical data and clinicians who need clear, timely answers while treating patients. The results are measurable. His AI and automation initiatives have produced tens of millions of dollars in savings, cut billing and inventory errors by double digits, and kept supply chains performing at benchmark levels for eight consecutive years.

    Research Meets Real-World Deployment

    Veernapu is also an active researcher and reviewer, authoring 25 peer-reviewed articles on healthcare AI and predictive analytics that have been cited and downloaded across more than 29 countries. He reviews manuscripts for Elsevier, Springer, Wiley, IGI Global, and MDPI, and has evaluated over 60 submissions for major IEEE, Springer, and Elsevier venues. He serves as a session chair, program committee member, and judge at international conferences, and is a Senior Member of IEEE.

    His research and his day job feed each other. Academic work surfaces new methods, and enterprise deployment tests whether those methods hold up once real data and real workflows get involved. That loop shapes his approach to AI at scale. “The algorithm is rarely the hard part,” he says. “Data quality, governance, and fitting a system into the way people already work are what determine whether a strong model delivers anything at all.”

    Looking Ahead: The Next Wave of Healthcare AI

    Looking forward, Veernapu points to AI-driven clinical decision support, remote patient monitoring, wearable health technology, and ambient clinical intelligence as the developments most likely to change care delivery. Each moves healthcare toward earlier intervention and more personalized treatment—and each depends on the real-time data infrastructure he has spent his career building.

    Beyond his technical work, he serves on the Utah STEM Education Advisory Council and speaks for academic programs internationally. He is currently pursuing a PhD in AI and machine learning applied to wearable devices and clinical bioinformatics. His advice to newcomers: “Start with a problem worth solving. Technology changes quickly. The ability to understand a business or clinical need and translate it into a working system is what creates impact that lasts.”

    The next generation of healthcare innovation will empower clinicians with intelligence of precision care, diagnostic accuracy, disease prediction, making patient care more reachable and affordable. The future of healthcare lies in turning data into better decisions. Clinical Decision Support Systems will help clinicians access timely insights, improve patient outcomes, reduce the cost of care, and enable more personalized and proactive treatment strategies.

  • Google’s AI Uses Smartphone Camera for Passive Heart Rate Monitoring with Medical Accuracy

    Google’s AI Uses Smartphone Camera for Passive Heart Rate Monitoring with Medical Accuracy

    Google researchers have developed a new deep-learning system that can passively measure a user’s heart rate through a smartphone’s front-facing camera during normal device use. The technology, described in recently published research, aims to bring medical-grade heart rate monitoring to billions of people without requiring any wearable hardware.

    Resting heart rate is a key biomarker linked to cardiovascular health and long-term disease risk. High resting heart rate is associated with adverse cardiovascular events and certain chronic conditions. With roughly five billion smartphones worldwide already equipped with the necessary camera hardware, the potential for widespread passive health monitoring is significant.

    How the System Works

    The system, called passive heart rate monitoring (PHRM), uses the front-facing camera to record short video clips of the user’s face. A temporal shift convolutional neural network then analyzes these clips to estimate heart rate. The method relies on detecting subtle changes in light reflection caused by blood pulsing through the skin—a technique known as remote photoplethysmography (rPPG).

    According to Google, the system achieves a mean absolute percentage error of less than 10%, meeting industry accuracy standards across all skin tones. “To our knowledge, PHRM marks the first large-scale demonstration of passive HR and daily RHR monitoring during everyday smartphone use,” said Eric S. Teasley, Product Manager, and Ming-Zer Poh, Staff Research Scientist at Google Research.

    The researchers added: “As the only rPPG method to meet heart rate accuracy standards for people of all skin tones – even in unpredictable real-world conditions – it sets a new standard for the field. It also represents the first use of rPPG to estimate daily RHR, achieving wearable-level accuracy across all skin tones.”

    Diverse Training Data and Real-World Testing

    Previous studies in this area have often underrepresented people with dark skin, as melanin can make optical signals harder to detect. To address this, Google’s team built their model using more than 350,000 video clips from nearly 700 participants. The Monk Skin Tone Scale was used to ensure diverse representation: participants with light and medium skin tones each comprised at least 25% of the datasets, while those with dark skin tones made up at least 33%. This makes it the largest and most diverse rPPG study to date.

    The system was tested in both laboratory and real-world conditions. In the lab, researchers recorded facial video and simultaneous electrocardiogram (ECG) data from 365 participants, and the PHRM system outperformed 15 leading published rPPG models. In a real-world study, 231 participants installed a data collection app on their phones and used them normally while wearing an ECG chest strap and a Fitbit tracker. The app captured an average of 231 video clips per day.

    The researchers note that further optimization of camera exposure and handling of excessive head movement could improve performance. Google plans to make its data and modeling resources available to qualified researchers.
