Daniela Hernandez is an award-winning science and health reporter at The Wall Street Journal, specializing in artificial intelligence applications in medicine, genetic research ethics, and climate-related health disparities. With a PhD in neurobiology, she brings academic rigor to stories that sit at the intersection of technology and public health.
We’ve followed Daniela Hernandez’s career as she transitioned from academia to becoming a leading voice in science and health journalism. With a PhD in neurobiology from Columbia University, Hernandez brings rigorous analytical skills to her reporting, particularly on topics like AI in healthcare and environmental science. Her early work at Kaiser Health News and WIRED laid the foundation for her current role as a health and science reporter at The Wall Street Journal, where she produces investigative pieces and video content.
This groundbreaking piece explores how machine learning algorithms are transforming diagnostic accuracy in hospitals. Hernandez interviewed clinicians using AI tools to detect cancers and rare diseases, highlighting both successes and ethical concerns about over-reliance on technology. Her analysis of FDA approval processes for AI-based devices revealed regulatory gaps that could impact patient safety.
In this WIRED feature, Hernandez examined CRISPR-modified crops through the lens of food security and ecological risk. She visited experimental farms in Kenya using drought-resistant maize, juxtaposing these innovations with concerns about corporate patent control. The article sparked debates at the UN Food and Agriculture Organization about equitable access to bioengineered crops.
This Kaiser Health News investigation revealed how telehealth expansion disproportionately excluded low-income communities. Hernandez analyzed Medicaid reimbursement data across 12 states, identifying systemic barriers to virtual care access. Her reporting influenced state-level policy changes in California and New York to fund broadband infrastructure for mental health clinics.
Hernandez consistently explores the practical hurdles of deploying AI systems in clinical settings. A successful pitch might examine how hospitals are addressing algorithmic bias in diagnostic tools, similar to her 2023 WSJ piece on racial disparities in AI-powered mammography analysis. Include data from peer-reviewed studies or interviews with medical ethicists to align with her investigative approach.
Her coverage of Zika and COVID-19 outbreaks demonstrates interest in environmental factors driving pandemics. Propose stories linking rising temperatures to vector-borne disease patterns, ideally with geographic specificity (e.g., dengue fever expansion in the southern U.S.). Field data from epidemiologists and climate modelers would strengthen such pitches.
Given her neuroscience background, Hernandez prioritizes stories that humanize brain-computer interface research. Pitch case studies of patients using neural implants, paired with technical analysis from engineers. Avoid speculative futurism—focus on technologies currently in FDA trials with verifiable trial results.
