**I am the recipient of the 2013 Doctoral Prize of the Canadian Mathematical Society..**

**Recently in the news: my HPV research.**

Currently, I am working on the following topics:

- Intratumor heterogeneity: spatial stochastic modeling
- HPV and cervical cancer: stochastic modeling at tissue-level
- Sexual networks and HPV vaccination: infectious disease dynamics on random dynamic graphs
- Synthetic biology: modeling of synthetically engineered bacterial cultures
- Bone remodeling: stochastic spatial models and evolutionary game theory
