Research Interests

Julieta Gruszko focuses on exploring Beyond-the-Standard-Model (BSM) physics via experimental tests of the properties of neutrinos. She is currently focused on measurements of neutrinoless double-beta decay, a proposed lepton-number-violating decay that would reveal the neutrino to be its own antiparticle. This process, if it exists, could prove key in understanding the origin of neutrino mass and the predominance of matter over anti-matter in our universe.

Julieta is particularly interested in developing new detection techniques to further the reach of experiments working at the intensity frontier. This class of experiments, which includes dark matter searches and searches for rare astrophysical and nuclear processes in addition to experiments in neutrino physics, allows us to probe the physics of the early universe. Julieta’s research focuses on how we can achieve the necessary levels of sensitivity by understanding and leveraging the physics of detectors.

Julieta also has a strong interest in improving outreach and mentoring efforts in STEM fields, particularly with respect to groups that are underrepresented in physics. She has worked with elementary school through graduate school-level students, as well as with the broader public.

Biographical Sketch

Julieta is originally from Buenos Aires, Argentina, and grew up in Poughkeepsie, New York. She completed her PhD as a National Science Foundation Graduate Research Fellow in Jason Detwiler’s group at the University of Washington, where she studied neutrinoless double-beta decay with the MAJORANA DEMONSTRATOR, and received her BS in physics and BA in mathematics from University of Rochester. In her spare time, she enjoys hiking, reading, and both playing and listening to music, in genres ranging from classical and bluegrass to electronic.
