2007–2008 Hummel attended
Purdue University to play under head coach
Matt Painter. He averaged 11.4 points (second on team), 6.1 rebounds (first) and 2.5 assists a game in his freshman year. Hummel led the "Baby Boilers", along with
Chris Kramer,
JaJuan Johnson, Keaton Grant, and
E'Twaun Moore, to a second-place finish in conference play and on to a second-round
NCAA tournament appearance, where they lost to a senior-led
Xavier team. He broke the school freshman record with a 44.7 three-point field goal percentage, while leading the
Big Ten Conference. He also recorded the highest free throw percentage for a freshman in school history with 86.5 percent accuracy, which led the team, and broke
Kyle Macy's 33-year-old .859 mark. He was named First Team All-Big Ten, becoming the first true
Boilermaker freshman to earn the honor. He finished his freshman season as one of 24
John R. Wooden Award finalists and of 10 finalists for the
Oscar Robertson Trophy. He helped lead the Boilermakers to a 25–9 overall season record. He finished the last five games as a junior perfect from the free throw line, making all 21 of his attempts. Playing 30.3 minutes per game, he averaged 15.7 points (2nd on team), 6.9 rebounds (1st), 1.1 steals, 1 block, and 2.1 assists, while shooting 45.6 percent from the floor and led the Big Ten at 90.2 percent from the line, while also leading the nation amongst players at the forward position. He also shot 36.4 percent beyond the arc (2nd). Hummel scored at least 11 points in all but three games on the season (24–3), including ten straight, while recording eight double-doubles and being named a First Team All-Big Ten selection for the second time in his career at Purdue, while also being named a
Fox Sports Third-Team All-American, a
State Farm and
NABC Second Team All-American, and an
Associated Press Honorable Mention All-American. He averaged 16.2 points and 7.3 rebounds per game in Big Ten Conference play for the third-ranked team in the nation (12–3). Hummel received knee surgery and had to wait 4 to 6 months for the healing process.
2010–2011 After two consecutive seasons with performance-affecting injuries, Hummel was expected to return for his senior season. Fellow teammates JaJuan Johnson and E'Twaun Moore were returning as well, where they pulled out of the
2010 NBA draft to return for their senior season. At team practice on October 16, Hummel tore the same ACL and was forced to sit out and serve as an assistant for the 2010–11 season. Before the injury, Hummel was predicted as high as a Preseason Second Team All-American by much of the media.
2011–2012 Hummel returned to the team as a fifth-year
redshirted senior. On October 19, 2011, he showed no effects from his injury during 3-on-3 fast-break drills in practice. Hummel was named one of 50 candidates for the
John R. Wooden Award, as well as the #24 player on
CBSSports.com Top 100 List and a Lowe's
Senior CLASS Award candidate to open the season. On November 11, the Preseason All-Big Ten selection scored 21 points, making 5-of-7 beyond the arc to open the season against
Northern Illinois in 20 minutes of play. On December 3 in a three-point loss at #11
Xavier, Hummel suffered from
cramps and
dehydration, which eventually caused him to fall to the floor in the last minute of the game. Hummel led Purdue to a 10–3 non-conference mark and onto a 10–8 conference record. Hummel led the Boilermakers with 16.4 points, 7.2 rebounds, and 1.2 blocks per contest, while averaging 2 assists and .7 steals. He scored in double figures in all but three games (1–2) this season, which included nine 20-plus-point games (7–2), while recording six double-doubles (4–2). On February 4, Hummel recorded a career-high 5 blocks in a home loss to #20
Indiana. On February 22, he scored a season-high 29 points in a home win against
Nebraska. Following that game and a 17-point performance win at #11
Michigan, Hummel was named Big Ten Player of the Week. In his last game at
Mackey Arena on February 29, Hummel recorded a career-high 6 assists, along with 26 points and 8 rebounds against
Penn State. Throughout the month of February, Hummel led the nation in points scored. After the culmination of the regular season, Hummel was selected First Team All-Big Ten for the third time in his career, becoming the first Boilermaker since
Rick Mount (1968–1970) to do so and the first Big Ten player since
Mateen Cleaves. Hummel led the Boilermakers to a sixth straight NCAA tournament, losing in his final game to Final Four-bound
Kansas in the third round by 3 points. Being guarded by
Thomas Robinson, Hummel scored 22 points in the first half, finishing with 26 points and 9 rebounds. He was named an
Associated Press Honorable Mention All-American and also won the Lowe's
Senior CLASS Award and the Thomas A. Brady Comeback Award.
