As many of you know, Bill Suk retired from NIEHS at the end of 2022, having expertly guided the Superfund Research Program (SRP) for 35 years. As we reflect on his leadership and vision for the program with immense gratitude, I want to assure you that during this time of transition, SRP will continue to operate, and our strong staff will continue to support your research endeavors, as usual. I will be serving as Acting Chief of the Hazardous Substances Research Branch and Director of the SRP while NIEHS searches for a permanent replacement over the next year.
