Expanding digital health innovation: ZS leads healthcare transformation from the Caribbean

Innovation doesn’t happen in isolation. It thrives through collaboration and a global perspective. That’s why ZS is committed to expanding its global footprint and investing in digital health talent. In 2021, ZS took a significant step by acquiring Medullan, a leader in digital health solutions and digital medicine strategy.

With this acquisition, ZS added two new offices in the Caribbean (Trinidad and Jamaica) and welcomed more than 80 talented professionals, including Kalisha Narine, an expert in healthcare technology implementation.

Where passion fuels healthcare innovation

Kalisha’s career began with a passion for programming. “My father, a math and IT teacher, inspired me early on,” she shares. With his guidance, she pursued a computer science degree and joined Medullan after graduation. Over the next 15 years, Kalisha held roles ranging from developer to delivery manager in the digital healthcare industry.

Today, Kalisha is an implementation services manager at ZS in Trinidad, supporting our digital health practice and helping deliver tech-driven solutions for global clients.

“My day-to-day work hasn’t changed much—I still collaborate with the same talented team,” she says. “But now, I work with improved tools and structured processes that come from being part of a larger, global consulting firm.”

“ZS has the energy of a startup backed by the stability, scale and resources of a global leader in healthcare consulting,” Kalisha adds.

Accelerating digital healthcare through Connected Research

Since joining ZS, Kalisha and her colleagues have helped scale ZS’s Connected Research platform, a modular solution for collecting real-world data (RWD) and real-world evidence (RWE) in clinical research.

Evolved from Medullan’s capabilities, Connected Research enables:

• Digital enrollment with electronic informed consent (eConsent)
• Electronic patient-reported outcomes (ePRO)
• Remote patient monitoring using wearable devices and sensors
• Telehealth and televisit services

The platform is designed as a flexible, hybrid digital ecosystem that supports rapid deployment and protocol-specific customization. This allows sponsors to increase patient engagement, improve retention and reduce participant burden—ultimately speeding up the path from clinical trial to patient care.

Creating tech opportunities for Caribbean healthcare professionals

ZS is proud to build healthcare technology with strategy and engineering talent in the Caribbean. Kalisha highlights how ZS is opening new pathways for regional professionals.

“In the Caribbean, tech education tends to be theoretical,” she says. “ZS gives us a chance to apply our knowledge to real-world projects that improve health outcomes.”

Through ZS internships, full-time roles and training programs, Caribbean professionals gain exposure to global healthcare challenges and contribute to innovative digital health solutions.

“One of the reasons I’m excited to stay at ZS is because I learn something new every day,” Kalisha says. “I love knowing that our work in healthcare technology makes a meaningful difference in people’s lives.”
