Taimiņa received all her formal education in Riga, Latvia, where in 1977 she graduated summa cum laude from the University of Latvia and completed her graduate work in theoretical computer science in 1990. At that time, a doctoral thesis had to be defended outside of Latvia, so she defended hers in Minsk, receiving the title of Candidate of Sciences. This explains the fact that formally Taimiņa's doctorate was issued by the Institute of Mathematics of the National Academy of Sciences of Belarus. After Latvia regained independence in 1991, Taimiņa received her higher doctoral degree in mathematics from the University of Latvia, where she taught for 20 years. Daina Taimiņa joined the Cornell Math Department in December 1996.
While attending a geometry workshop in 1997, she saw fragile paper models of hyperbolic planes, designed by geometerWilliam Thurston. She decided to make more durable models, and did so by crocheting them. Due to her success in this she was invited, together with her husband David Henderson, a math professor also at Cornell, to give a presentation at a Cornell workshop. Crocheted mathematical models later appeared in three geometry textbooks they wrote together, of which the most popular is Experiencing Geometry: Euclidean and non-Euclidean with History. An article about Taimiņa's innovation in New Scientist was spotted by the Institute For Figuring, a small non-profit organisation based in Los Angeles, and she was invited to speak about hyperbolic space and its connections with nature to a general audience which included artists and movie producers. Taimiņa'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, Taimiņa soon became popular as a fiber artist and public presenter for general audiences of ages five 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 Washington, D.C. Since then she has participated regularly in various shows in galleries in US, UK, Latvia, Italy, Belgium, Ireland. Her artwork is in the collections of several private collectors, colleges and universities, and has been included in the American Mathematical Model Collection of the Smithsonian Museum, Cooper–Hewitt, National Design Museum, and Institut Henri Poincaré. Her work has received wide interest in media. It has been written about in 'Knit Theory' in Discover magazine and in The Times, explaining how a hyperbolic plane can be knitted by increasing the number of stitches: Margaret Wertheim interviewed Daina Taimiņa 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 to incorporate Taimiņa'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 Los Angeles Times. Taimiņa'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.
