She did her postdoctoral research with George Whitesides at Harvard University, investigating micro/nanofabrication and near-field optics. In 1998, she joined Bell Labs as a member of the technical staff where she has made a number of pioneering contributions, including developing new biomimetic approaches for the synthesis of ordered mineral films with highly controlled shapes and orientations, and discovering unique biological optical systems that outperform technological analogs, as well as characterizing the associated organic molecules.[4]
The lab's research investigates a wide range of topics that include biomimetics, self-assembly, adaptive materials, crystal engineering, surface wettability, nanofabrication, biooptics, biomaterials, and biomechanics.[6]
In 2019, Aizenberg was elected into the National Academy of Engineering for contributions to the understanding of biological systems and bioinspired materials design.
