Zack's current interest lies in making sense of large, real-world datasets via curent computing techniques. Recently, he has been mining social networks and trying to leverage "social" and "local" for ubiquitous activity recognition. He is currently working on the SmartDAYS project in the Wearable Computing Lab. In the past, he studied intelligent systems for robotics and heuristic-based optimization techniques.

Zack completed his undergraduate studies at the University of Waterloo in Systems Design Engineering. As part of his studies, he completed various internships in the US and Canada at organizations such as Sun Microsystems Laboratories (now Oracle Labs), Defence R&D Canada, and Research In Motion. Upon graduation, he continued his studies at ETH Zurich with a masters in Computational Science and Engineering. During this time, he exchanged at the Hong Kong University of Science and Technology. In 2011, he completed his master thesis analyzing the YouTube social network at Google Zurich.
