Dean Bollero

Dear ACES family and friends,

The College of Agricultural, Consumer and Environmental Sciences has been my academic home for more than 30 years. I am honored to lead our community of changemakers. Together, we are transforming our world for the better by:

  • Nurturing ecosystems and communities
  • Creating more sustainable food systems
  • Making education more accessible and inclusive
  • Pioneering research and spurring economic development

My philosophy is people first. As we shape our future, I look forward to engaging with each of you to deliver on our land-grant mission. This is such an exciting time for the College of ACES, and I can’t wait to see what we can do together.

Yours sincerely,
