Research:

Much of my work as a Plant Ecologist at the Illinois Natural History Survey focuses on plant communities across Illinois, how communities have changed over time, and factors associated with those changes. 

Additional research interests include
-Rare plant species biology and conservation
-Population genetics
-Plant reproductive biology
-Demography
-Invasive shrubs and shrubland birds

Also, I'm interested in all things Celastrus (bittersweets, or staff vines).

Recognition:

It can be confusing, because I often change the length of my hair and beard.  But, I'm usually wearing field boots.
