I have studied host-microbe interactions using laboratory, computational, and field approaches & tools. I love working on plants and fungi, in particular. I also build bioinformatics resources to facilitate biology research, such as ontologies & genome annotation pipelines.

When you take a look at my papers, you may notice that I have: (i) annotated & analyzed genomes from across the tree of life; (ii) frequently studied oomycetes and fungi; (iii) worked on multiple ontologies; (iv) performed both laboratory and computational research; (v) collaborated on diverse projects, large and small, sometimes as lead author and sometimes in the middle of the pack; and (vi) published the vast majority of my work as open access—so that anyone can read it and learn from it.

I hope you enjoy reading my work!
