Welcome to the Ignace Lab!

We are broadly trained ecophysiologists studying the world’s most pressing environmental problems. Our goal is to answer one question: How does global change affect ecosystem function? 



Meet the Ignace Lab

The Ignace Lab is growing and we always welcome new members. Be sure to check out our YouTube channel for videos.

Ignace Lab PODCAST

The lab hosts several podcast series, including Bio Banter and Cool People I Know. Check back regularly for our podcast series.


Lab News & Announcements

New podcast coming soon!!!

Manuscript accepted for publication!

Be sure to check out PLOS ONE soon (early October) for the latest publication.

Determinants of temperature sensitivity of soil respiration with the decline of a foundation species

New publication alert!

Hot off the press (early September) is our new collaborative project featuring Eastern Hemlock trees. A big congratulations goes to Aliza Fassler, who was a Smith student and first author on the paper.

Loss of a foundation species, Eastern Hemlock (Tsuga canadensis), may lead to biotic homogenization of fungal communities and altered bacterial abundance in the forest floor.

First video: A teaser trailer for our new summer video series.

Check out a day in the field measuring photosynthesis at Harvard Forest featuring Lony. Lony is doing a stellar job for their REU project and makes this all look easy. Enjoy!

Latest videos!

Check out a recent video and learn how we are using new cameras and drones to assess Eastern Hemlock tree health. Environmental Science & Policy major, Steph Long, talks us through this complicated process. Enjoy!

Congratulations to Maddy Meadows-McDonnell!

Maddy was awarded by the NSF GRFP! Maddy starts her PhD at the University of Connecticut in the Natural Resources and the Environment Program this fall. Her work will address how shifts in salt marsh plant species dominance associated with human activities alter patterns of carbon sequestration and the stability of soil organic matter.

New collaboration for summer 2019

The Ignace Lab has a new project at Harvard Forest: “The future of the Harvard Forest - Tree seedlings of Prospect Hill”. I will be mentoring REU students along with collaborators from Bryn Mawr College, Wellesley College, Darthmouth College, and UC Davis.
