Chris Gatti's (@bearded_mann) background includes time in both academic and acrobatic domains. He holds degrees in mechanical engineering, biomedical engineering, and machine learning and data analysis. In part, his research experience includes approximately five years doing computational shoulder biomechanics in an orthopaedic laboratory and his dissertation work focused on reinforcement learning. After completing his PhD, he joined Cirque du Soleil as an artist to perform on tour in South/Central America, and he has since been a Head Coach and consultant for Cirque du Soleil as well. Currently, he pursues a variety of independent activities including handstand training and teaching (his passion), academic editing, and circus research.

I've linked his website here: https://www.chrisgatti.com/ in case you're interested in reading his blog (lots of gems in there! OR his academic editing OR handstand coaching (though as you'll here, he isn't as much a fan of online coaching).
