Dariush died Feb. 3, 2012, after living with neuroendocrine cancer for nearly a decade.

Born in Ann Arbor, Mich., Dariush grew up in Bethesda, Md. At age 9, he lived for a year with family in his father’s native Iran. He graduated from Walt Whitman High School in Bethesda, received a bachelor’s degree in civil engineering from Princeton, and earned a master’s degree in mechanical engineering from UC Berkeley.

A scientist at Lawrence Berkeley National Laboratory for 30 years, Dariush was known worldwide for his research on energy-efficient windows. Central in developing the window performance rating used today in the United States, he authored over 100 academic papers and co-authored two books.

Dariush will be remembered for mentoring young scientists and collaboratively bringing emerging technologies to market. A natural athlete, he enjoyed everything from tennis and ultimate Frisbee to rowing and hitting home runs. He was deeply engaged in his son’s life, from hobbies to schoolwork.
