Helen Gregory

Senior Toxicologist

UKRT/ERT

Helen joined bibra in 2017, having previously worked as an analytical chemist and forensic toxicologist for nearly twenty years. She has an honours degree in biochemistry and toxicology from the University of Surrey and is a RSB/BTS and European Registered Toxicologist (ERT).

Helen has worked for clients from a range of industrial sectors, including consumer products, food/food contact, pharmaceuticals and medical devices. She routinely performs hazard and/or risk assessments on chemicals, including additives, flavourings, pharmaceutical impurities, degradants, and extractables and leachables. She also evaluates the biocompatibility and safety of medical devices in compliance with ISO 10993 and ISO 18562. Another area of interest is endocrine disruptors and the regulation thereof. Helen has produced extensive reviews of the state-of-the science for clients, and has been involved in data collation for plant protection products.

Helen is also involved in the production of bibra’s monthly publication, Toxicology and Regulatory News, writing and/or peer-reviewing brief evaluative summaries describing critical developments and reports relevant to the field of mammalian toxicology.

Following a brief “rest” over the various Covid lockdowns, Helen hopes to return to her work as a STEM ambassador. In her remaining spare time, she enjoys yoga and Pilates, cooking and reading Scandinavian crime thrillers. She doesn’t enjoy running but will apparently “grow to love it”.
 

Helen's case studies and blog posts

Toxicological risk assessment of leachables from a combination product

Case study

The client was developing a ready-to-use (RTU) process for the administration of a viral-based product in a clinical setting. Bibra was requested to assist with the assessment of extractables during the development phase and leachables in the final RTU process - viral vector product.

Evaluation of the endocrine-disrupting potential of a plant protection product

Case study

The Plant Protection Products Regulation (EC) No 1107/2009 is amended by Regulation (EU) 2018/605, requiring that information on the potential endocrine-disrupting properties of such products must be collated and evaluated. The European Chemicals Agency (ECHA) and the European Food Safety Authority (EFSA) have published “Guidance for the identification of endocrine disruptors in the context of Regulations (EU) No 528/2012 and (EC) No 1107/2009”, detailing the performance of such hazard identification, together with an Excel spreadsheet to be used as a template for gathering the necessary information on “human and animal health” and “non-target organisms”.

Literature monitoring for an industry group

Case study

The scientific literature can provide an early indicator of potential changes in the regulatory status of chemical substances. Organisations representing different chemical sectors may therefore provide services to their members that keep them up to date with the latest relevant publications on the toxicology of their chemicals in humans and other animals, as well as their persistence in the environment.
