On behalf of the other contributors to Skeptic North, it’s my pleasure to welcome Richelle McCullough as a new contributor to the blog. Richelle is a first-year medical student living in Calgary, but hails originally from Winnipeg. An outspoken advocate for lifestyle interventions within the scope of science-based medicine, Richelle’s favourite topic is to debunk complementary and alternative medicine. She is frequently trolled by geocentrists at her personal blog, Subspecies, and despite the distance, remains active with the Winnipeg Skeptics. Want more? Connect with Richelle on Twitter. You’ll see Richelle’s first post tomorrow.
