- Postdoctoral Research Associate - Chicago Botanic Garden, 2012-2014
- Research Associate - The Field Museum, Chicago, 2011 - present
- Adjunct Faculty - Lake Forest College, Fall 2012 and 2014
- Phyloecology in a restoration context (with Dan Larkin)
- Artocarpus (breadfruit and jackfruit) genetics (with Nyree Zerega)
- Lepidospartum burgessii (broomsage, scalebroom) population genetics and conservation (with Jeremie Fant)
- Botrychium s.s. (moonwort) fern systematics and population genetics
- Rare plant ecology, conservation, and restoration
My research interests encompass a range of subjects including restoration ecology and genetics, population structure, rare plant conservation, and species concepts, with natural history a constant interest and hobby.
