Two Purdue University professors are being recognized for their research in chemical engineering computing. - Daniels School’s new leadership team in place
Since being unveiled as Purdue University’s next big move one year ago, the Mitchell E. Daniels, Jr. School of Business is gaining momentum, evidenced by a $50 million gift from the Lilly Endowment for the school’s new building, a $50 million gift from the Dean and Barbara White Foundation, and recognition as a game-changer in shaping the future of business education. - Purdue trustees approve Krannert School named and distinguished faculty positions
The Purdue University Board of Trustees on Friday (June 14) ratified seven named and distinguished faculty positions, including three within the Krannert School of Management. David Hummels was named a Distinguished Professor of Economics, Mohit Tawarmalani was named the Allison and Nancy Schleicher Chair in Management, and Annabelle Feng was named the John and Donna Krenicki Chair in Operations Management. Trustees also issued resolutions of appreciation for friends of the university whose names will be added to campus facilities.
