Ko ia te Ahorangi Eberly o te Physics me te Kaiwhakahaere o te Institute for Gravitational Physics and Geometry i te Whare Wananga o Pennsylvania State. Ko te kaihanga o nga taurangi Ashtekar, ko ia tetahi o nga kaiwhakaara o te taurangi quantum taurangi me tana waahanga iti. Kua tuhia hoki e ia etahi whakaahuatanga o te taurangi quantum taurangi e waatea ana ki te hunga kaore i te ahupūngao. I te tau 1999, i taea e Ashtekar me ona hoa te tatau i te entropy mo te poka pango, e rite ana ki te matapae 1974 rongonui a Hawking i Oxford. Kua whakaahuahia e te kairangahau matatini a Roger Penrose te huarahi a Ashtekar ki te taumaha nui hei "Te mea nui rawa atu o nga mahi katoa ki te 'antiquising' o te taurangi whanui". I tohua a Ashtekar hei mema o te National Academy of Sciences i te Mei 2016.
