Nohria, is the first Indian-origin dean in the Schools 102-year-old history.
The School had announced in May that Nohria will succeed Jay Light as the 10th Dean and will take up his new role on July 1.
Member of the HBS faculty since 1988, Nohria has previously been the Schools senior associate dean for faculty development and chair of its organisational behaviour unit.
He is current co-chair of the HBS Leadership Initiative.
I feel a profound sense of responsibility for continuing Harvard Business Schools proud legacy of groundbreaking ideas and transformational educational experiences, Nohria had said after his appointment.
With business education at an inflection point, we must strive to equip future leaders with the competence and character to address emerging global business and social challenges, he added.
Nohria received his bachelor of technology degree in chemical engineering in 1984 from IIT Mumbai and later did his Ph.D. in management from the Massachusetts Institute of Technologys Sloan School of Management.
He joined the HBS faculty as an assistant professor in 1988, was appointed associate professor in 1993, was promoted to tenure in 1997 and became the Richard P Chapman Professor of Business Administration in 1999.
In a conference call with Indian media soon after his appointment, Nohria had said during his years at IIT-Bombay, he learnt that I could survive anything.
He had named his father, KK Nohria, former head of the electrical equipment company Crompton Greaves, as another big influence in his life.
The great leadership advice has been from my father: Try to be yourself and try to be humble.
Nohria takes over as dean just as the HBS enters into its second century of existence and said his objective is to have a period of extraordinary innovation at HBS.
His new responsibilities may not give him time for his first love teaching.
But I will do everything I can to at least remain very connected with our students and to find some opportunity to be in our classrooms, he said.
