after graduate school, milliron held a post-doctoral research position at the ibm t.j. watson research center and was then a research staff member at the ibm almaden research center. at ibm, milliron's publication record included studies on phase change nanomaterials and topics relevant to self-assembly of nanostructures. she also notably contributed to innovations in the field surrounding preparation of metal-chalcogen clusters and applications therof. in 2008, milliron transitioned to lawrence berkeley national lab where she led a research team as a staff scientist in the inorganic nanostructures facility of the molecular foundry. milliron served as the deputy directory of the molecular foundry at large from 2008 to 2012. during her time at the foundry, milliron would continue to contribute to fundamental questions in nanoscience with technological impact. she contributed to advances in robotic nanocrystal synthesis through the development of wanda with her then post-doc emory chan. and importantly for applications energy sciences, she began to explore topics relevant to innovations in window coating technology. milliron's research continued to be distinguished by advancing fundamental knowledge in the field of nanoscience through studies on mixed ionic and electronic conductors, plasmonic nanocrystals, nanocrystal assemblies, and nanocrystal phase transitions.
