We develop microrobots for medical applications. The goal is to develop more targeted, active, but less invasive strategies for drug or cell delivery with the help of wireless, autonomously moving microrobots. One strategy is to combine biological elements with artificial components in a biohybrid approach. The biological component (cells, molecules) can serve as power source, loading unit or structural unit.
One example is the "spermbot" - a sperm cell remotely controlled with magnetic fields: https://phys.org/news/2014-01-sperm-bots-desired-video.html
Another example is IRONSperm: a magnetically functionalized nonmotile sperm driven by magnetic fields:https://www.science.org/doi/10.1126/sciadv.aba5855
Inspired by the motion of sperm, we also develop small scale flexible magnetic robots for noninvasive surgery (coming soon). I am also interested in reproductive biology and research that elucidates reasons for infertility. We look into the mechanisms of sperm migration and some interesting phenomena, such as sperm bundling (publication online soon)

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
