As of 2020 she is a tenure-track assistant professor at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland, where she directs the Laboratory for Functional Inorganic Materials.

From 2011 to 2012 she was a visiting scholar in laboratory of Jeffrey R. Long[2] at University of California Berkeley before returning to the Center for Neutron Research as a postdoctoral fellow with Craig Brown.

[7][8] Queen's research is focused on the synthesis and characterization of novel porous adsorbents, namely metal-organic frameworks, and their corresponding composites, which are of interest in a number of host-guest applications.

[9] Her research aims at contributing knowledge towards solving globally relevant problems, like reducing energy consumption,[10] cutting CO2 emissions,[11][12] water purification,[13] the extraction of valuable commodities from waste,[14][15] and chemical conversion processes.

[16][17] Queen became known to a wider audience through her TEDx Talk on "Cut Carbon to Save Lives",[18] her Aeon article on "Could mining gold from waste reduce its great cost?
