The Mildred S. Christian Career Achievement Award

ATS established the Mildred S. Christian Career Achievement Award to honor the memory of Dr. Christian, known to many as “Millie.” She gave much of her time and financial resources to the Academy and helped to make the ATS into an efficient and scientifically recognized organization. Many of the policies and practices used today benefit from her efforts.

The award is conferred upon an ATS Fellow who has clearly demonstrated a lasting impact on toxicological sciences. The criteria for the award include, but are not limited to, the following:

  1. The awardee must be an ATS Fellow in good standing as either a full ATS Fellow or ATS Emeritus. A Fellow that is a current member of the Board of Directors of ATS is not eligible to receive the award.
  2. The awardee must have demonstrated extraordinary scientific achievement through publications, professional activities, and/or leadership that have enhanced the practice of toxicology as judged by the Board of Directors.


The ATS Board of Directors is requesting nominations from the ATS Fellows for the 2025 Mildred S. Christian Award.

All nominations for the 2025 award must be submitted on the official ATS Mildred Christian Award Nomination form, available by clicking on the link below.  While the candidate’s CV must accompany the nomination form, the nominator must also describe on the form how they believe their candidate meets the criteria for the award.  Only one secondary letter per candidate is requested.  If more are submitted in addition to the one listed on the nomination form, the Awards Committee will consider these at their discretion.  Note that nominations submitted in 2023 for the 2024 award do not need to be resubmitted.

If you believe an ATS Fellow meets the criteria for this award, we request that you submit the nomination form along with the nominee’s biographical information (complete CV if possible) to Susie Masten at for the Board’s consideration. The deadline for receipt of nominations and secondary letters for the 2025 award is November 1, 2024.
