Over the last decade, exposure science has experienced much change. As a growing field of science, we have blossomed and matured, demonstrating the value we have to offer public health. Change is inevitable, yet it is also a time for reinvention or reinvigoration. On 1 January 2011, I took over the presidency of the International Society of Exposure Science (ISES). Because this is such a vital position in ISES, I decided to not seek renewal of my contract as the Editor-in-Chief of the Journal of Exposure Science and Environmental Epidemiology (JESEE). This was a bittersweet decision, but the only logical one that would allow the continued and focused support of both ISES and JESEE. A search committee led by Debbie Bennett conducted an extensive search campaign and selected Morton Lippmann as the new JESEE editor-in-chief. Mort comes to JESEE with a great deal of experience, knowledge and an extensive network. He is one of the founding members of ISES and has strong, solid roots in exposure science. I am certain he will work diligently to take JESEE to further heights than previously believed imaginable.

It has been both a privilege and an honor to serve such a quality journal that is steadily growing in readership and importance in our field. With your continued input, quality reviews, and excellent manuscripts, and support of our new editor-in-chief, JESEE will continue to have an important and positive impact in exposure science.

Before signing off as JESEE's editor-in-chief, I would like to take a moment to reflect on some very talented scientists who have touched many lives within our community. Last year, we saw the passing of two devoted ISES members: former ISES president Larry L. Needham and former JESEE editorial board member Natalie Freeman. These two individuals devoted a large portion of their life to improving our understanding of exposures and ways to mitigate these exposures and reduce any resulting health impacts. I hope you all take a moment to reflect on their many contributions to our field. They will be greatly missed by so many who counted on their knowledge, ingenuity, enthusiasm and friendship.

I am hoping that 2011 will be a pivotal year in pushing both JESEE and ISES in positive paths forward. Mort has some great ideas to implement into JESEE activities to increase the impact and visibility of JESEE. In turn, the ISES board is working on many exciting elements to grow our society and our science. Here's to a fruitful and lucrative 2011!
