Personal life
Marla Sokolowski was born in Toronto in 1955 to Ruth and Ernest Berger- the latter of which was a Holocaust survivor who immigrated to Canada where he worked as a shoe salesman. Sokolowski is married to Allen Sokolowski, who worked as a dentist and taught at the University of Toronto's School of Dentistry. They have two children: one daughter, Moriah Sokowski (born 1991) and one son, Dustin Sokolowski (born 1995).

Academic career
Research
Sokolowski completed her undergraduate degree at the University of Toronto in Zoology in 1977. Sokolowski's early research into evolutionary biology was influenced by Richard Lewontin and Douglas Wahlsten. At the time, very few scientists believed that it was possible for genes to influence normal individual differences in behaviours. This set the stage for Sokolowski's 1980 Ph.D thesis and subsequent research into behavioral genetics.
Sokolowski's research has definitively demonstrated how genes interact with the environment, and thus have an impact on behaviour. She has pioneered the development of a branch of behaviour genetics that addresses the genetic and molecular bases of natural individual differences in behaviour. This is demonstrated most clearly in her discovery of the foraging(for) gene.
By mapping the movement patterns of Drosophila, she discovered a single gene that influenced the style of foraging that they used. Sokolowski's subsequent cloning of this gene, which she named foraging (for), was the first ever molecular characterization of a gene which regulates normal individual differences in a behaviour. This gene has since been studied in many other animals, including humans. Sokolowski demonstrated that the for gene can be influenced by the environment of the individual: this means that the style of foraging is dependent on the life that the individual has lived.
Sokolowski has applied her work to early childhood development, demonstrating how children who are at risk can benefit from nutritional, financial, educational and emotional interventions.
