As the Chief of AI for Science Innovation, I lead a team dedicated to accelerating drug discovery and transforming clinical development in oncology and biopharmaceuticals R&D. Our focus is to achieve this through the development and implementation of innovative, impactful AI solutions that are reusable at scale. We are using frontier AI solutions to power advanced foundation models and agentic frameworks, as well as building potentially transformational new technologies aligned to AstraZeneca's bold ambitions. These technologies could be strategically crucial in the development of next-generation therapies that have the potential to improve patients’ lives.
My previous roles within AstraZeneca include the Chief AI and Data Scientist, Oncology R&D and Vice President of Cancer Biomarker Development. In these roles, I spearheaded the development and deployment of multimodal foundation models, advanced data science approaches, and agentic AI frameworks to drive innovation throughout the company’s oncology pipeline and portfolio. This included the creation and clinical validation of novel biomarkers, which significantly enhanced our ability to select treatments and therapeutic combinations tailored precisely to each patient’s clinical journey.
With a background in molecular pathology, bioinformatics, functional genomics, and artificial intelligence, I joined AstraZeneca in 2023 as the VP of Cancer Biomarker Development. In this role, I led teams dedicated to developing and meticulously validating mechanistically informed yet clinically deployable biomarkers for patient selection and prediction of therapy response. Key innovations included the Quantitative Continuous Scoring (QCS) computational pathology biomarkers, as well as pioneering approaches leveraging ctDNA and proteomics to guide clinical decision-making and enhance therapeutic outcomes.
Prior to joining AstraZeneca, I served as the Chief of Experimental Pathology at Memorial Sloan Kettering Cancer Center where I leveraged my expertise to bridge academic medical research with biotechnology and pharmaceutical industries. I have also served on numerous scientific advisory boards, on the Board of Directors for Grupo Oncoclínicas, and as a consultant for multiple biotech companies and Goldman Sachs Merchant Banking. In these roles, I shaped healthcare, healthtech, biotech, and big data strategies designed with the aim of transforming cancer diagnosis and treatment through omics technologies and computational pathology approaches. My experience further includes senior editorial responsibilities at leading journals, including The Journal of the National Cancer Institute, The Journal of Pathology, and npj Breast Cancer.
I have a passion about nurturing the next generation of scientists and promoting diversity within the scientific community. Throughout my career, I have collaborated with talented individuals from diverse backgrounds, united by a shared commitment to harnessing science for positive change.
My work surrounds the intersection of artificial intelligence and data science with the aim to drive therapeutic progress that has the potential to meaningfully improve patient outcomes.
