Hi and welcome! I have just sent you a welcome message with info about the site and a link to the doctors list, but you were quick off the mark and have already posted! There’s one mention of a doctor working out of IU:
Dr. David Campell - works out of IU Health, Avon & Carmel, IN, https://iuhealth.org/find-providers/provider/david-a-campbell-md-2911865?utm_source=Google&utm_medium=Yext&y_source=1_ODMzMTgzNjYtNzE1LWxvY2F0aW9uLndlYnNpdGU%\\\\\\\\\\\\*\*\\\*
Here’s a link to when his name was mentioned by @Redirish98
I hope this is helpful!
