and completed her graduate work in theoretical computer science (supervised by Prof. Rusins-Martins Freivalds) in 1990. At that time, a doctoral thesis had to be defended outside of Latvia, so defended hers in Minsk. This explains the fact that formally Taimina's doctorate was issued by the Institute of Mathematics of the Belorussian Academy of Sciences. After Latvia gained independence in 1991, Taimina received her doctorate in mathematics from the

, and she was invited to speak about hyperbolic space and its connections with nature to a general audience which included artists and movie producers. Taimina's initial lecture and following other public presentations sparked great interest in this new tactile way of exploring concepts of hyperbolic geometry, making this advanced topic accessible to wide audiences. Originally creating purely mathematical models, Taimina soon became popular as a fiber artist and public presenter for general audiences of ages 5 and up. In June 2005, her work was first shown as art in an exhibition "Not The Knitting You Know" at Eleven Eleven Sculpture Space, an art gallery in

Her work has received wide interest in media. It has been written about in 'Knit Theory' in Discover magazine. The Times (Alex Belos “How Crochet Solved age-old Math Problem”, The Times, July 1, 2008 ) Margaret Wertheim interviewed Daina Taimina and David Henderson for Cabinet Magazine

Later, the Institute For Figuring published a brochure "A Field Guide to Hyperbolic Space". In 2005 the IFF decided that to incorporate Taimina's ideas and approach of explaining hyperbolic space in their mission of popularizing mathematics, and curated an exhibition at Machine Project gallery, which was the subject of a piece in the

Taimina's way of exploring hyperbolic space via crochet and connections with nature, combatting math phobia, was adapted by Margaret Wertheim in her talks and became highly successful in the IFF-curated Hyperbolic Crochet Coral Reef project.
