Who is Dr. Mian Endelecki from Forward the Foundation and what is their importance?

Dr. Mian Endelecki is the white-haired but youthful-looking biophysicist whom Hari Seldon selects to map his granddaughter Wanda's genome, Endelecki explains the complexities and the enormous cost. She is unwilling to lose her license by testing a minor without her parents' permission, forcing Hari to convince Wanda's parents. Endelecki explains the painless procedure and lengthy analysis and a frustrating month later presents the reports to Hari. There is nothing remarkable about the DNA responsible for Wanda's brain structure.
