Answer by taking a quote from the following article:

John Craig Venter (born October 14, 1946) is an American biotechnologist, biochemist, geneticist, and businessman. He is known for being involved with sequencing the second human genome and assembled the first team to transfect a cell with a synthetic chromosome. Venter founded Celera Genomics, The Institute for Genomic Research (TIGR) and the J. Craig Venter Institute (JCVI). He was the co-founder of Human Longevity Inc., served as its CEO until 2017, and is executive chairman of the board of directors.

Venter was passionate about the power of genomics to radically transform healthcare. Venter believed that shotgun sequencing was the fastest and most effective way to get useful human genome data. The method was rejected by the Human Genome Project however, since some geneticists felt it would not be accurate enough for a genome as complicated as that of humans, that it would be logistically more difficult, and that it would cost significantly more.  Venter viewed the slow pace of progress in the Human Genome project as an opportunity to continue his interest in patenting genes, so he sought funding from the private sector to birth Celera Genomics. The company planned to profit from their work by creating genomic data to which users could subscribe for a fee. The goal consequently put pressure on the public genome program and spurred several groups to redouble their efforts to produce the full sequence. Venter's effort to publish a draft genome of his own DNA won him renown as the second person to sequence the human genome after the public effort, thus making it impossible to patent any of it.  In 2000, Venter and Francis Collins of the National Institutes of Health and U.S. Public Genome Project jointly made the announcement of the mapping of the human genome, a full three years ahead of the expected end of the Public Genome Program. The announcement was made along with U.S. President Bill Clinton, and UK Prime Minister Tony Blair. Venter and Collins thus shared an award for "Biography of the Year" from A&E Network. On the 15 February 2001, the Human Genome Project consortium published the first Human Genome in the journal Nature, and was followed, one day later, by a Celera publication in Science. Despite some claims that shotgun sequencing was in some ways less accurate than the clone-by-clone method chosen by the Human Genome Project, the technique became widely accepted by the scientific community.  Venter was fired by Celera in early 2002. According to his biography, Venter was fired due to a conflict with the main investor, Tony White, specifically barring him from attending the White House ceremony celebrating the achievement of sequencing the human genome.

What did he do after that?
