Career
After his medical internship and US Army service (1945–48), and working at the military hospital of Nancy, he became a researcher at Columbia University College of Physicians and Surgeons (1948–50). He performed research in Paris (1950–56), relocated to New York University (1956–68), moved to the National Institutes of Health (1968–70), then joined Harvard University medical school (1970–91) where he became the Fabyan Professor of comparative Pathology, concurrently serving the Dana-Farber Cancer Institute, Boston (1980). He began studies of allergies in 1948, and discovered the Ir (immune response) genes that govern transplant rejection (1960s). Counting different editions, he is an author of over 300 books and articles
Baruj first start in the field of immunology was started the Columbia University of Physicians and Surgeons with Elvin Kabat. He spent two years there working on experimental hypersensitivity mechanisms. He then moved to Paris because of family issues and accepted a position in Bernard Halpern’s laboratory at the Broussais Hospital. Here he also formed a close relationship with a young Italian scientist, Guedo Biozzi. For six years he worked on the reticuloendothelial function in relation to immunity. The reticuloendothelia function is the white blood cells inside of a barrier tissue. While there they discovered techniques to study the clearance of particulate matter from the blood by the RES (reticuloendothelial system), and devised equations that govern this process in mammals. After six years Baruj returned to the United States because he could not make his own independent laboratory in France. In the U.S. he developed his own libratory in New York City and returned to study on hypersensitivity. In New York, Baruj worked with several other immunologists on different fields of hypersensitivity. After working in his New York lab, Baruj started to turn his attention more to the train of new scientists. Also in this time frame Baruj made the decision to devote himself to his laboratory practices, instead of the family business. At this time Baruj also made the discovery that would go on to win him the Nobel Prize. He noticed that if antigens (something that causes a reaction with the immune system) where injected into animals with a similar heredity, two group immerged, responders and non-responders. He then conducted further study and found that the dominant autosomal genes, termed the immune response genes, determined the response to certain antigens. This complex process would led to the understanding of how these genes would determine immune responses.
His discovery still holds true, and more has been discovered over the last century. More than 30 genes have been discovered in a gene complex called the major histocompatibility complex. The histocompatibility complex is a complex part of DNA that controls the immune response. This research has also lead to clarify auto immune diseases like multiple sclerosis and rheumatoid arthritis.

Famous quotes containing the word career:
“I doubt that I would have taken so many leaps in my own writing or been as clear about my feminist and political commitments if I had not been anointed as early as I was. Some major form of recognition seems to have to mark a woman’s career for her to be able to go out on a limb without having her credentials questioned.”
—Ruth Behar (b. 1956)
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
“Work-family conflicts—the trade-offs of your money or your life, your job or your child—would not be forced upon women with such sanguine disregard if men experienced the same career stalls caused by the-buck-stops-here responsibility for children.”
—Letty Cottin Pogrebin (20th century)
