Genetics Engineering:-

Genetics engineering is the application of physical and scientific principles for solving the problems of society with regarding to study of gene and making advancement of human body by modifying or altering that gene structure.

This is subfield of bioengineering.

Humans have altered the genomes of species for thousands of years through selective breeding, or artificial selection[20]:1[21]:1 as contrasted with natural selection. More recently, mutation breeding has used exposure to chemicals or radiation to produce a high frequency of random mutations, for selective breeding purposes. Genetic engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed since the 1970s. The term "genetic engineering" was first coined by Jack Williamson in his science fiction novel Dragon's Island, published in 1951[22] – one year before DNA's role in heredity was confirmed by Alfred Hershey and Martha Chase,[23] and two years before James Watson and Francis Crick showed that the DNA molecule has a double-helix structure – though the general concept of direct genetic manipulation was explored in rudimentary form in Stanley G. Weinbaum's 1936 science fiction story Proteus Island.

Here are some notable Genetics engineers.
