About Toyoko Orimoto

Prof. Toyoko Orimoto is an Associate Professor of Physics at Northeastern University. Prof. Orimoto is an experimental particle physicist who studies the smallest constituents of nature using one of the world’s largest science experiments–the CMS Experiment at the CERN Large Hadron Collider in Geneva, Switzerland. As part of the CMS Collaboration, Prof. Orimoto is interested in using the recently discovered Higgs boson particle as a probe for new beyond-the-Standard-Model physics, such as supersymmetry and extra dimensions. Moreover, Prof. Orimoto works on the CMS electromagnetic calorimeter and the new CMS MIP timing detector.

Prior to joining the Northeastern faculty, Prof. Orimoto was a fellow at CERN (2009-2012) and the Robert A. Millikan fellow at the California Institute of Technology (2006-2009). For her PhD at the University of California, Berkeley, she studied charge-parity asymmetry with the Babar Experiment at the Stanford Linear Accelerator Center.

In addition to her passion for elementary particles, Prof. Orimoto advocates for diversity, equity, and inclusion in all spheres–in her collaborations, in physics, at the University, and in society at large.

We study precision measurements of Standard Model processes and are searching for signatures of new physics, including leptoquarks, dark matter candidates in topologies with Z bosons and invisible decays, and exotic production and decays of Higgs bosons.
