Suleman Dawood, a business student, died, and according to a university in Scotland, both staff and students are "shocked.".
Five people died on the Titan submersible, which vanished last Sunday, including the 19-year-old and his 48-year-old father Shahzada.
On Thursday, the US Coast Guard announced that they had discovered the ship's components among the rubble close to the Titanic's wreckage.
It was consistent with a "catastrophic implosion of the vessel".
Glasgow's University of Strathclyde was Suleman's place of study.
He enjoyed playing volleyball and reading science fiction books. He also enjoyed Rubik's cubes.
He had just finished his first year at Strathclyde Business School and was a former student of ACS International School Cobham in Surrey.
The University of Strathclyde released the following statement on Friday: "The staff and students at Strathclyde have been shocked and profoundly saddened by the deaths of Suleman Dawood and his father in this tragic incident.
The entire student body of the university extends its sincere condolences to the Dawood family and everyone else impacted by this terrible accident.
In this trying time, Suleman's Strathclyde classmates and the larger community can get the support they need from our student wellbeing team. ".
After the Titan lost contact on Sunday, it was revealed that the US Navy had first picked up "an acoustic anomaly consistent with an implosion.".
About 1,600 feet (480 meters) away from the shipwreck it was observing, a robotic diving vehicle discovered significant sub fragments on the seafloor.
Suleman's father came from one of the wealthiest families in Pakistan and is the vice-chairman of Pakistani conglomerate Engro Corporation, a sizable fertiliser company.
He and wife Christine have another child, Alina. Prior to the dive, the family was spending a month in Canada.
The Dawood family released a statement in which they expressed their condolences to the people who had died in the tragedy, which had garnered worldwide attention.
It brings out the best and worst in people, as with any tragedy of this magnitude.
"Some go out of their way to contribute and support, others use these moments for personal gains. How one behaves in such circumstances reveals more about their own character than anything else. ".
It ended: "The family remains overwhelmed with the love and support that it has received and is grateful to the those who showcased the best in humanity. ".
Shahzada Dawood was a founding patron of Prince's Trust International. The charity said it was deeply saddened by the tragedy and "valued [the Dawood family's] support of our work in Pakistan for many years".
The British Asian Trust also paid tribute to Shahzada, describing him as a "wonderful and generous man who supported our work in South Asia for many years" and his son Suleman as someone who was "just emerging into adulthood with a promising future ahead".
His family said he was interested in "exploring different natural habitats", and had previously spoken at both the United Nations and Oxford Union.
The father and son were on board the sub with British adventurer Hamish Harding, former French Navy diver Paul-Henry Nargeolet and Stockton Rush, the chief executive of OceanGate, which runs the Titanic voyages.
OceanGate charges $250,000 per person for the deep-sea excursion to the Titanic shipwreck, which sits 3,800m (12,500ft) beneath the surface of the Atlantic.
Titan and its passengers were at the centre of a huge international rescue mission, which included a Scottish ship normally used to work on pipelines in the North Sea.
The Aberdeenshire-based Deep Energy had remote submersibles that reach the 3,800m (12,500ft) depth of the Titanic wreck to search for the missing vehicle.
A large RAF plane also left Scotland for Canada to join the search operation.
A C17 Globemaster loaded with ancillary equipment - believed to be cables - departed from RAF Lossiemouth at around 15:00.
A second plane - and Atlas A400M - was scheduled to leave later, transporting specialist loaders and crew.
