Alexander Amberg performed his doctoral studies at the department of toxicology and pharmacology at the University Wuerzburg and obtained his PhD in biochemical toxicol­ogy in 2000. In 2001, he joined the early and exploratory safety group of Sanofi, and in this position has been responsible for in silico/computational toxicology analysis glob­ally at Sanofi. Since 2007, he has been registered as a European registered toxicologist (ERT) after getting his examination of Fachtoxikologe DGPT from the German Society of Toxicology. His major research interests are development of new in silico prediction models for different toxicity endpoints and data management of in-house data in com­bination with publicly available toxicity data, to support drug development in research and development. For this he is also a member of different internal expert advisory groups as well as external initiatives, like the IMI eTOX consortium (for toxicity data sharing and development of new expert systems for in silico toxicity prediction), the IMI SafeSciMET education program and others. With respect to genotoxic impurities (GTIs), he was actively involved in the preparation of the White Paper for the use of in silico systems in the scope of ICH M7 and other publications regarding GTIs. Internally he is member of the task force to support the in-house implementation of ICH M7.

Manuela Pavan provides toxicology consulting services to the industry for the evaluation of human health endpoints, including the genotoxic and carcinogenic potential assessment of pharmaceutical impurities. Her main interest lies in the use of in silico approaches (read-across, QSAR, alerts, grouping, categories) that the industry uses in compliance with regulations such as ICH M7, REACH, CLP guidelines, biocides, and cosmetics guidelines; she is then committed to combining information and data coming from different sources in an efficient and informed way. Her experience thus includes topics such as weight of evidence, integrated testing strategy, chemical safety assessment. She was working for the former European Chemicals Bureau (ECB) at JRC of the European Commission from 2004 to 2008, where she was actively involved in developing technical guidance documents for REACH.
