David is also one of the most prolific researchers in the world across a broad range of interests, such as resistance training, balance, and neuromuscular responses to stretching – among many others – with over 200 peer-reviewed articles and over 11,000 citations, and he ranks within the top 2.5% of the most productive researchers in the world, according to ResearchGate. He has made many public appearances on television, radio, and on new media, in addition to being featured in mainstream newspapers and fitness magazines.
With his own athletic background of having been a junior ice hockey player, being drafted into the Canadian Football League, and being a provincial champion in both Tennis and Squash, David’s interests, research, and engagement with the public are informed by his desire to bridge the gap between these worlds for everyone’s benefit.
