She edited the journal from 2011 to 2014, and was instrumental in moving the journal to Oxford University Press and establishing the journal web page. She helped negotiate the contract with Oxford, which strengthened ASEH’s financial position.

Langston has contributed significantly to a number of ASEH conferences, chairing the Program Committee for the Victoria conference in 2004 and the Local Arrangements Committee for Madison in 2012. In numerous lectures and editorials, she has drawn academic and public attention to the field of environmental history as a whole.
