Jack Szostak joins the Sydney Farber Cancer Institute (now Dana-Farber Cancer Institute) and sets up his own laboratory and research group. He works on telomeres in Tetrahymena and on the study of double-strand breaks in DNA and their repair by recombination.

Jack Szostak stays at the laboratory of Ray Wu for his postdoctoral studies. He collaborates with R. Rothstein to get practical experience with yeast genetics. Szostak combines molecular biology and genetics to study the unequal sister chromatid exchange in rDNA locus.

Jack Szostak, Elizabeth H. Blackburn and Carol W. Greider are awarded the Nobel Prize in Physiology or Medicine in 2009 for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.

Jack Szostak collaborates with Elizabeth Blackburn to test the ability of Tetrahymena telomeres to function in yeast. They are able to clone bona fide yeast telomeres and to obtain the critical sequence information that leads to the proposition of the exsistence of the key enzyme, telomerase.

Jack Szostak enters McGill University and graduates in cell biology in 1970.

Jack Szostak is appointed full professor at the Harvard Medical School and becomes an Investigator for the Howard Hughes Medical Institute in 1998.

Jack William Szostak is born in London in 1952. He grows up in Montreal and Ottawa.

Jack Szostak is offered a position at the Department of Molecular Biology at the Massachusetts General Hospital. He switches fields to work on ribozymes, including the origins, possibilites and limits of RNA. By the year 2000 Szostak becomes more interested in compartmentalization, cellular structure and membrane biophysics. His laboratory focuses on the origins of life and the construction of artificial cellular life.

Jack Szostak participates in The Jackson Laboratorys Summer Student Program under Chen K. Chai. The program offers intense scientific education and experimental work. Szostak analysis the thyroid hormones of mice in various mutant strains. He decides to never use animals for research again.

Jack Szostak attends Riverdale High School (Quebec). He is interested in mathematics and chemistry. Szostak's parents further encourage his passions and install a small laboratory in their basement.

Jack Szostak continues his studies at McGill University and works in various laboratories in biology and biochemistry on plant biology systems. He colaborates with Joachim Sparkhul and discovers that the green flagellate Eudorina elegans secrets a peptide hormone that induces spermatogenesis under favorable environmental conditions. Szostak earns his Master degeree in 1972.

Jack Szostak attends Cornell University and collaborates with John Stiles on the chemical synthesis of a DNA oligonucleotide that hybridizes to a single sequence within the yeast genome and is used as an mRNA and gene specific probe. He earns his Ph.D. in 1977 under the supervision of Ray Wu.
