Samuel H. Wilson Memorial meeting: DNA Damage & Repair

Inspiring basic and applied research on the crucial importance of genome maintenance mechanisms

Date/time: Saturday, August 27, 2022, 7:00am - 3:40pm ET

Chair: Robert Sobol, University of South Alabama, Mobile, AL, USA

Description: This one-day session will highlight cutting edge research from both established leaders and junior trainees on DNA repair mechanisms, with emphasis on their importance for basic and environmental health sciences. The session will exemplify the same dedication to scientific discovery and support for trainees that was a lifelong pursuit of Sam Wilson over his productive and impactful career. You can register for the Samuel H. Wilson Memorial meeting on DNA Damage & Repair on the ICEM 2022 Registration form, whether or not you attend ICEM.

9th International Workshops on Genotoxicity Testing (IWGT)


You will be aware that at IWGT our preferred format is on-site attendance in order to maximize interactions with the Working Group members. However, in view of the continued Covid-related travel restrictions, we anticipate many interested scientists may not be allowed to attend IWGT in person. We therefore decided to extend the options to join IWGT remotely, and to move towards a “hybrid” format.

We will therefore now accept registrations from scientists who want to attend IWGT remotely, and to do so scientists should use the below link to register and identify that they will be attending virtually. The registration fee will remain at 250 Euro.

Register for IWGT here!  

Date/time: August 23 - 26, 2022, 8:30AM

The 8th International Workshops on Genotoxicity Testing (IWGT), a satellite meeting of the ICEM, will be held
August 23 - 26, 2022 at the nearby University of Ottawa. The goal of the IWGT is to gain consensus on current
issues and approaches in genetic toxicology. World-leading experts representing different subject areas are
assembled; recommendations on test systems, strategies and approaches are discussed and debated. The outcome,
with accompanying consensus statements, are published in a peer-reviewed scientific journal. The 8th IWGT will
include Working Groups that collectively address the following topics:

  • Transcriptomic Biomarkers
  • Predictivity of In Vitro Genotoxicity Testing
  • Genotoxicity dose-response Analysis for Potency Comparisons and Risk Assessment
  • In Vivo Genotoxicity Assessment Strategies
  • Statistical Approaches and Data Interpretation

In addition, two plenary sessions will provide state-of-the-art information pertaining to:

  • Epigenotoxicity and Germ Cell Effects
  • Gene Therapy

Guests are welcome to observe and contribute to the discussions. For more information on registration and
participation, please visit https://iwgt.org
