Episode 58 | Today, you're gonna hear from Heather Caslin, PhD. Heather completed her B.S. and M.S. degrees in exercise physiology at Virginia Commonwealth University. In that time, she fell in love with health, nutrition, and exercise, but had a lot of questions about how they affect our immune system. That interest led her to complete a PhD in immunology. Her dissertation work bridged her interests between immunology and exercise physiology as she studied the effects of lactic acid on mast cells in sepsis and allergic disease. That dissertation project sparked her current interests in how metabolism and immunology intersect—which she's still studying today. Heather is now a postdoctoral researcher at Vanderbilt University in the lab of Alyssa Hasty studying how the immune system contributes to obesity and type 2 diabetes. Specifically, she studies how weight loss and weight regain influence the relationship between adiposity and type 2 diabetes in adipose tissue immune cells. While her primary job is in academic research, she also has a passion for education and science outreach...which is why I wanted to interview her on my podcast! In the episode, Heather tackles topics like whether or not vaccines contain unsafe toxins, whether or not the flu vaccine can give you the flu, why some people think vaccines cause autism...and more! Enjoy!!
