<human>: Answer by taking a quote from the following article:

Biden was born on November 20, 1942, at St. Mary's Hospital in Scranton, Pennsylvania, to Catherine Eugenia "Jean" Biden (nee Finnegan) and Joseph Robinette "Joe" Biden Sr. He was the first of four siblings in a Catholic family, with a sister, Valerie, and two brothers, James and Frank, following. His mother was of Irish descent, with roots variously attributed to County Louth or County Londonderry. His paternal grandparents, Mary Elizabeth (Robinette) and Joseph H. Biden, an oil businessman from Baltimore, Maryland, were of English, French, and Irish ancestry.

During a tour of the U.S. Senate with reporters before leaving office, on December 5, 2016, Biden refused to rule out a potential bid for the Presidency in the 2020 presidential election, after leaving office as Vice President. If he were to run in 2020, Biden would be 77 years old on election day and 78 on inauguration day in 2021. He reasserted his ambivalence about running on an appearance of The Late Show with Stephen Colbert on December 7, in which he stated "never say never" about running for President in 2020, while also admitting he did not see a scenario in which he would run for office again. He seemingly announced on January 13, 2017, exactly one week prior to the expiration of his vice presidential term, that he would not run. However, four days later, on January 17, he seemed to backtrack, stating "I'll run if I can walk." A political action committee known as Time for Biden was formed in January 2018, seeking Biden's entry into the race.  In 2017, he was named the Benjamin Franklin Presidential Practice professor at the University of Pennsylvania, where he will focus on foreign policy, diplomacy, and national security while leading the Penn Biden Center for Diplomacy and Global Engagement. He will also pursue his "Cancer Moonshot" agenda. On March 12, 2017, Biden during a keynote speech at the annual SXSW festival stated, "The only bipartisan thing left in America is the fight against cancer."  On April 21, 2017, amidst speaking to a New York urban planning conference, Biden cited the "infinite wisdom" of Governor of New Jersey Chris Christie as the cause behind the termination of a rail tunnel project and called the Gateway Program "the most important infrastructure project in America."  During a Las Vegas, Nevada hedge fund conference interview on May 18, Biden said that he had never been confident in Clinton's candidacy: "I never thought she was a great candidate. I thought I was a great candidate."  Biden delivered a speech to the graduating class of Colby College on May 21, 2017, calling for a return to "unity and purpose", and three days later expressed confidence in contemporary students being able to handle "the challenges that lie ahead" at Harvard University during the college's Class Day ceremony.

is he doing anything else?
