معرفی
Helinor Jane Johnston is a Professor in the School of Engineering & Physical Sciences at Heriot-Watt University, specializing in nanomaterial toxicity, environmental health, and alternative testing methodologies. She leads research on nanomedicine development, particulate air pollution impacts, and ecotoxicological effects of engineered materials. Her work emphasizes sustainable innovation through rigorous safety assessments and alternative models.
Education: PhD in Pharmacology & Toxicology (Edinburgh Napier University, 2008); MSci in Pharmacology & Toxicology (King's College London, 2005). Professional Experience includes roles as Deputy Director of Heriot-Watt's Nano-Safety Group and Defra Scientific Advisor (2009-2010).
Research interests span nanomaterial toxicity mechanisms, in vitro testing alternatives (zebrafish models, organ-on-a-chip systems), and nanomedicine applications. Current projects investigate nanoparticle impacts on liver, lung, immune systems, and environmental ecosystems. She collaborates globally on air pollution studies in urban and wildfire-affected regions.
Her recent publications focus on nanosafety frameworks, dispersion protocols' impact on toxicity, and PM2.5/PM10 pollution in Southeast Asia. She actively promotes intelligent testing strategies to reduce animal use and streamline risk assessments.
Grants and collaborations include EU-funded projects (ENRHES, PARTICLE_RISK) and partnerships with organizations like NC3Rs and Unilever. She advises policymakers on nanotechnology regulation and delivers public outreach through science festivals and U3A lectures.
Labs/Teams: Leads the Nano-Safety Group, collaborates with Edinburgh Napier University, King's College London, and international partners in Thailand and Europe.
