As a freshman in the 2008–09 season, Boyd averaged 10.5 points and 6.4 rebounds per game, earning Northeast ConferenceRookie of the Year honors. Following his freshman campaign, Boyd was diagnosed with noncompaction cardiomyopathy. He was forced to sit out the 2009–10 season with a medical redshirt. Boyd came back the following season, averaging 13 points and 8.9 rebounds per game and leading the Blackbirds to a 27-6 record and NEC regular-season and tournament titles. LIU made the 2011 NCAA Tournament, falling in the second round to number two seed North Carolina. Boyd was named first team All-Conference and Northeast Conference Player of the Year.

In the offseason prior to the start of his senior season, Boyd was one of four Blackbirds players suspended following a fight at a campus party. After the school reviewed the matter, the four were reinstated to the team and Boyd and his teammates each received two-game suspensions. However, Boyd's troubles for the season did not end as he tore the Anterior cruciate ligament in his knee in a game against Rice on December 12, 2012, ending his season after only eight games. Boyd was granted a sixth year of eligibility by the NCAA. In July 2013, Boyd again tore his ACL and was expected to miss most of the 2013–14 season. LIU coach Jack Perri advised that Boyd would return to the Blackbirds' lineup in January 2014 at the earliest. However, Boyd re-tore his ACL for a third time during a non-contact drill in late December 2013, officially ending his college career.
