Dr Wu

Dr. Henry Wu is a major character and villain in Jurassic Park, possibly the overarching antagonist in the franchise. He is the geneticist that recreates the dinosaurs in all Jurassic Park media. He is the chief genetic engineer of InGen.

Henry Wu was a major character in the book, but in the the film he was only a minor character with the majority of his role being taken over by Mr. DNA. In Jurassic World, Henry Wu appears as a secondary character, serving as a foil for Masrani's moral opposition to gene splicing, creating the hybrid Indominus rex.

Cloning dinosaurs
Henry Wu is a Chinese American from Ohio with a PhD in genetics. He is a senior member of InGen's project to recreate the dinosaurs. Dr. Wu and paleo-geneticist Dr. Laura Sorkin were the top minds in the project.

When the team had discovered large amounts of dinosaur DNA, Dr. Wu proposed that they could start to clone dinosaurs by filling in the missing parts of the dinosaur genome (DNA) with DNA from extant species. Laura Sorkin opposed this idea and wanted to wait with the cloning until they had recovered 100% of a species' genome. The board of investors preferred Wu's approach because it was faster, easier and cheaper. Thus, the board gave Dr. Wu a promotion to be the chief geneticist.

Wu decided to use the DNA of several species of amphibians, including the Common reed frog (Hyperolius viridiflavus), to supplement the dinosaur DNA. The first prehistoric animal was cloned in 1986. Wu also decided to build in a few safety measures. The dinosaur chromosomes were designed such that all animals were female, so they could not reproduce. He also made the dinosaurs unable to produce Lysine, so they would die without the supplements in their food.
