Miles was born in the suburbs of Chicago and moved to Dallas at the age of seven. From an early age, he was interested in playing Xbox and watching SpongeBob. He attended college at Southern Methodist University, where he majored in Biology. He then attended medical school at the University of North Texas Health Science Center. While in medical school, he developed an interest in pediatric neurology and child development after spending time with some of the wonderful physicians at Cook Children's Medical Center. He is proud to be a resident in the Vanderbilt child neurology program.

Outside of medicine, Miles is a classical music fanatic. He especially likes the music of Mahler, Berlioz, and (if he has 2 hours to kill) Bruckner. He is also a barbecue enthusiast and holds the honor of being the world's most mediocre tuba player.
