Erika Tobiason Hamden is an American astrophysicist and associate professor at the University of Arizona and Steward Observatory.

She joined Columbia University for her doctoral studies in 2007, earning a PhD supervised by David Schiminovich [Wikidata] in 2014.

[10] The fellowship allowed her to develop instrumentation to study galaxies in the Keck Cosmic Web Imager redshift range.

[13] Here she is building a UV detector lab and continuing work on FIREBall-2 and as the project scientist for the Keck Cosmic Reionization Mapper.

[8] The electron multiplying charge-coupled devices (EMCCDs) can suffer from clock-induced charge and spurious signals and require carefully designed shaped pixel clocks to minimize noise.

[20] Hamden is a member of the Goddard Space Flight Center Cosmic Origins Science Working Group.
