X-ray line searches are sensitive probes for many dark matter models, such as sterile neutrino dark matter in the nuMSM. I will discuss the current status of the experimental efforts, including that of the tentative signal at 3.5 keV.  Then I will discuss some recent progress with NuSTAR and its prospects in the near future.  Finally, I will talk about the idea of dark matter velocity spectroscopy, a powerful diagnostic tool for tentative dark matter line signals, which is achievable with high-resolution spectrometers, such as XRISM and Athena.

I did my PhD at Ohio State University, and then a postdoc in the Weizmann Institute of Science. I am now a Marie Curie fellow at the GRAPPA Institute at the University of Amsterdam.  In 2020 I will start at the Chinese University of Hong Kong as an assistant professor.
