Students and Research Team
In addition to teaching, I enjoy mentoring students on masters‑ and
PhD‑level research projects.
If you are a current University of Iowa student interested in my work,
please contact me.
Prospective students are encouraged to apply through the Department
of Biostatistics graduate program.
