"I'm extremely humbled and excited to be the next head coach at Penn State University," Shrewsberry said.
"The values of this university and its commitment to excellence are the major reasons why this job was so appealing to me. I can't wait to arrive on campus to begin working with our tremendous student-athletes."
Pat Chambers, who had been the Nittany Lions' head coach since 2011, resigned in October after an investigation into allegations of inappropriate conduct. Jim Ferry took charge this past season on an interim basis.
Shrewsberry is a longtime assistant coach under Brad Stevens and Matt Painter at the college and NBA levels. The Indianapolis native spent three seasons under Stevens at Butler -- helping lead the Bulldogs to back-to-back national championship game appearances. He then went to Purdue for two seasons as an assistant coach under Painter before reuniting with Stevens for six years with the Boston Celtics.
Shrewsberry returned to the college game in 2019 as the associate head coach under Painter at Purdue.
With the Celtics, Shrewsberry worked with and aided in the development of young stars Jayson Tatum and Jaylen Brown. He has also been tasked with running Purdue's offense the past couple of seasons; the Boilermakers rank in the top 25 nationally in offensive efficiency this season.
"Micah was a name that immediately jumped to the top of our list with his experience in the Big Ten and the NBA," vice president for intercollegiate athletics Sandy Barbour said. "He has had success at all levels and knows what it takes to develop a program into a consistent national contender. He has learned from and worked under some of the most respected coaches in the country in Brad Stevens and Matt Painter. Micah will be an exceptional leader for the young men in our basketball program and I can't wait for him to get to know our student-athletes."
