Chicago took Portis (6-11, 253) with the 22nd pick of the 2015 NBA Draft on Wednesday night.
"I think I will fit in well," Portis said. "They have Pau Gasol and Taj Gibson there. I am going to back those guys up, maybe even try to start and try to learn from them a little bit..
Portis is coming off a sophomore season in which he was named a first-team All-American and also the SEC Player of the Year.
"He's a big guy who can play inside or out," said new Chicago head coach Fred Hoiberg, whose Iowa State team played Arkansas last season.
Bulls' general manager Gar Forman was pleased that Portis fell to Chicago.
"He's a guy we think really fits our team and the makeup of our team," Forman said. "We've had people just rave about his work ethic, how hard he plays, his makeup and character. And we really like his game. He's a big who can play inside and outside.
"We're always going to draft who we think is the best player available. And we had him ranked as a late lottery player."
He averaged 17.5 points and 8.9 points per game and blocked 50 shots while shooting over 53.6 percent from the field and 73.7 percent from the free throw line.
"He plays hard," ESPN commentator Jay Bilas said. "There were three guys in college basketball that scored over 600 points and grabbed over 300 rebounds. - Jahlil Okafor, Frank Kaminsky and this guy Bobby Portis. He is 6-10 with a 7-2 wingspan. He can go over either shoulder in the post.
"He and has a really good turnaround jumper over either shoulder in the post and not everybody has that. Most guys go over their strong shoulder. He can go both ways. Not a great athlete, but a good rebounder and I think because of his work ethic he is going to be a very good NBA player."
Portis, Arkansas' sixth draft pick in the last 20 years after 21 picks in the previous 20 seasons, was the SEC player chosen with Kentucky’s Karl Anthony-Townes going No. 1 overall.

Three other Kentucky players went before Portis with Willie Cauley-Stein taken sixth by Sacramento, Trey Lyles taken 12th by Utah and Devin Booker 13th by Phoenix.
"In adding the power forward from Arkansas, the Bulls’ front office showed it has some concerns with the front court," Cowley wrote. "Joakim Noah is playing with a surgically repaired left knee that is bone-on-bone, Pau Gasol is 34 years old and Taj Gibson just had surgery on his left ankle. He’s expected to stay away from basketball activity for the next four months.
It also could have shown that the Bulls will continue trying to shop Noah, who will be entering the final year of his contract."
