About Lucy

A former cancer researcher, Lucy brings a strong technical background to her work with organizations across the life-sciences sector. Since joining McKinsey, she has partnered with CEOs and top teams at leading organizations across North America, Europe, and Asia. She leads our evidence generation work within the Life Sciences Practice, helping clients generate and apply research insights, clinical data, and real-world evidence to maximize patient benefit, demonstrate product value, and catalyze innovation.

Whether working with established pharmaceutical companies to hone R&D investments and optimize commercial operations, or advising healthcare providers on growth and innovation, Lucy takes a strategic, long-term perspective. Given her background in oncology, she often works with clients in the optimization of asset-development and commercialization plans as well as improving specialized-care delivery approaches.

Examples of her recent client work include the following:

  • advising a biopharmaceutical company setting clinical, regulatory, and medical strategies for a suite of treatments for infectious diseases and oncology
  • supporting a leading pharmaceutical company through digital transformation to transform how it engages with customers, applies advanced analytics, and embeds agile ways of working
  • assessing internal and external portfolio-productivity and pricing models to optimize the R&D strategy and redesign the organization for a top pharmaceutical company
  • developing a corporate growth strategy for a top US cancer center
  • designing an operating model for a new innovation center at a major academic medical center to boost the translation of biomedical research into clinical-care solutions
  • designing a US regional commercial model for the field force of a leading pharmaceutical company to better respond to the needs of integrated health systems

In addition to her client service, Lucy co-leads our North America Hispanic Latino Network, a platform for consultants and Hispanic and Latino leaders to connect and build community as well as advance their professional development.

Before joining McKinsey, Lucy was a research fellow at Memorial Sloan-Kettering Cancer Center, where she was involved in the development of novel treatments for solid tumors. She was also a Howard Hughes Medical Institute research fellow at Harvard University while completing her doctoral studies. She is co-inventor on multiple patents and has published in peer-reviewed journals.
