Alisa Machner studierte Geowissenschaften an der FAU in Erlangen. Anschließend promovierte sie 2018 an der NTNU in Trondheim, Norwegen. Während ihrer Promotion war sie bei Norcem AS, Norwegen, als industrial PhD tätig, und konnte ihre Forschung in industriellen Fragestellungen bei der Herstellung von neuartigen Kompositzementen anwenden. Im Anschluss daran arbeitete sie unter anderem im Horizon2020 Projekt EnDurCrete als PostDoc an der NTNU, bis sie im September 2020 auf die Professur für Mineral Construction Materials an der TU München berufen wurde.

Alisa Machner (*1989) beschäftigt sich mit den fundamentalen Mechanismen der Hydratation und der Dauerhaftigkeit mineralischer Bindemittel. Ziel ihrer Forschung ist es die ökonomische und ökologische Effizienz solcher Materialien sowohl während ihrer Herstellung als auch in ihrer Anwendung zu optimieren. Um die Wirkungsweise umweltverträglicher und nachhaltiger Bindemittel zu erforschen, kombiniert sie experimentelle Laboruntersuchungen mit thermodynamischen Modellierungen.
