ISRTP has collaborated with the Society of Toxicology (SOT) Regulatory and Safety Evaluation Specialty Section (RSESS) annually since 2010. to contribute toward the ISRTP/RSESS student and post-doc awards. These are awards for the best student and post-doc posters addressing an area of interest to ISRTP and is presented at the RSESS meeting at the annual SOT meeting.
ISRTP Recognizes Excellence in Regulatory Science at the 2026 SOT Annual Meeting
The International Society of Regulatory Toxicology and Pharmacology (ISRTP) is pleased to announce the recipients of the 2026 ISRTP Award for Excellence, presented at the Society of Toxicology (SOT) Annual Meeting. This year’s awards were given in two specialty section sessions — the Risk Assessment Specialty Section (RASS) and the Regulatory and Safety Evaluation Specialty Section (RSESS) — recognizing researchers whose work exemplifies the scientific rigor and regulatory relevance that ISRTP champions.
Dr. Chander Kant Negi — Risk Assessment Specialty Section (RASS)

Dr. Chander Kant Negi received the ISRTP 2026 Award for Excellence in recognition of his paper, “Comparative Analysis of Species-Specific Hepatocyte Function and Drug Effects in Static Monolayers, Spheroids, and a Perfused Microphysiological System.”
This research addresses a central challenge in regulatory toxicology: how to improve the predictive accuracy of laboratory models used to assess drug-induced liver toxicity across different species. By rigorously comparing traditional static cell cultures, three-dimensional spheroid models, and a state-of-the-art perfused microphysiological system — often called an organ-on-a-chip — Dr. Negi’s work offers practical guidance for both laboratory scientists and the regulatory professionals who evaluate pharmaceutical safety submissions. The cross-species methodology and use of advanced in vitro platforms reflect the kind of innovation that directly supports more scientifically defensible regulatory decision-making.
ISRTP congratulates Dr. Negi on this well-deserved recognition and looks forward to his continued contributions to the field.
Hannah Roe — Regulatory and Safety Evaluation Specialty Section (RSESS)

Hannah Roe received the ISRTP 2026 Award for Excellence in recognition of her paper, “ECHA Writes Back: The Reasons for Rejection of Read-Across in Compliance Check Decisions by the European Chemicals Agency.”
This study provides a systematic, evidence-based analysis of how the European Chemicals Agency (ECHA) evaluates read-across submissions under the REACH regulation, and — critically — what specific scientific and data-quality factors most frequently lead to rejection. As regulatory agencies and industry scientists worldwide increasingly rely on read-across and other alternative approaches to animal testing for chemical hazard assessment, understanding the basis for agency decisions is essential. Roe’s research fills a meaningful gap, offering actionable insight for practitioners preparing and defending read-across cases before regulatory authorities in Europe and beyond.
ISRTP congratulates Hannah Roe on this outstanding achievement and welcomes her to the ISRTP community.
