Research & Development

Meet our team of experts

Cutting-edge is precisely the place that Gerakopulos and his R&D team like to work. The growing team has deep roots in advanced nanotechnology, chemistry, and innovation culture; multiple PhDs in material science;  others have Masters-level degrees in mechanical and mechatronics engineering. Among their achievements: 

Gerakopulos, who has an M.ASc. in mechanical and mechatronics engineering from the University of Waterloo, has co-authored 13 peer-reviewed scientific publications and is the founder of NanoQuan, a materials science and nanotechnology startup. The co-inventor of eight pending patents, he was the recipient of the 2019 Innovation Award from the Institute of Electrical and Electronics Engineers (IEEE) for innovations in nanotechnology related to new techniques for fabricating nanocomposites. 

The Nam Long Doan, with a Ph.D. in chemical engineering from the Tokyo Institute of Technology, has co-authored more than 30 peer-reviewed scientific publications and is the co-inventor of three pending patents.

Chad Smithson holds a Ph.D. in chemical engineering from McMaster University and has an expertise in multi-layered printed electronics and ink technology.

The Future

“We’re introducing things into the building and construction space that is radically new,” says Gerakopulos. “To do so, we have to be very methodical. Scientifically we have to be deliberate. It’s all about credibility and trustworthiness – we know how to chart our path forward. We know there are successful, important, outcomes out there.” 

Or, to put it another way, success for Trusscore is tied to material science. And where does it all lead?
