On June 8, 2017, Olivier Ouellette, Mathieu Lempen, Marc Lejay, and Emma Howard welcomed a distinguished delegation of visiting scholars from Brown PS French Immersion Class Grade 4-5.

Ph.D Candidate Olivier Oulette recently gave an invited lecture to the grade 4-5 class at Brown Public School in Toronto. Olivier spoke about solar cells and quantum dots to a group of bring young future scientists!

Susan Leggett and Ian Wong from Brown University wrote for News & Views in Nature Nanotechnology on a recent Sargent-Kelley article on sorting circulating tumor cells using magnetic fields. 

You can read the feature article below:

“Catching Tumor Cells in the Zone”

It was recently Graduate Research Days (GRD) at the University of Toronto this February 23rd – 25th. GRD is an engineering faculty-wide event where prospective students from all over Canada visit the University of Toronto to learn about their departments, meet professors and students, and get tours of the campus. 

This year many of the graduate students in the Sargent group volunteered for GRD attending the networking events, giving student lab tours, and participating in panel discussions. Ted also met with a few enthusiastic and exceptional students to discuss coming to work for the Sargent group. 

A special thank you to the following students! 

• James
• Monorina
• Olivier
• Phil
• Rafa
• Surath
• Wendi
