School's not quite out for Wayne Brodland who retired from Waterloo Engineering last year.

After more than three decades of teaching and conducting research, he launched the Brodland Commons website, which provides students and others with access to resources he and his teams developed over the years.

The now civil and environmental engineering professor emeritus, pictured here, and his students carried out fundamental research on the mechanics of biological cells. Their goal was to understand how and why cells move during embryogenesis and cancer metastasis.

“One of our favorite discoveries is a new technique that makes it possible to infer the forces in cells from their geometry,” says Brodland on his website. “We made a short video to describe how this novel technique works, and we wrote some sample software that you can download.”

The site also includes YouTube videos to help students around the world learn about various engineering structures.

At least one of those videos - Retaining Walls modeling - has gone viral with more than half a million views.
