[5] Regev is a pioneer of single cell genomics and of computational and systems biology of gene regulatory circuits.

Regev studied at the Adi Lautman Interdisciplinary Program for Outstanding Students of Tel Aviv University, where she completed her PhD under the supervision of Eva Jablonka,[7] and Ehud Shapiro.

Regev's research[11] includes work on gene expression[12][13] (with Eran Segal and David Botstein), and the use of π-calculus to represent biochemical processes.

[14][15][16] Regev's team has been a leading pioneer of single-cell genomics experimental and computational methods.

Regev founded the Human Cell Atlas together with Sarah Teichmann along with collaborators all over the world.
