Dr. Logan's research centers on understanding the origin of mass through Higgs physics, particularly investigating properties of the Higgs boson discovered in 2012. Her work explores extended Higgs sectors including two-Higgs-doublet models, Georgi-Machacek models, and connections to dark matter. She develops theoretical frameworks to generate testable predictions for experiments at the Large Hadron Collider and future colliders. Her recent publications demonstrate expertise in charged Higgs bosons, CP violation, and custodial symmetry in extended scalar sectors.

Analysis of her 15 most recent publications reveals consistent focus on Higgs physics within extended scalar sectors, with particular emphasis on the Georgi-Machacek model and two-Higgs-doublet frameworks. Her work bridges theoretical developments with experimental constraints from LHC data, frequently addressing vacuum stability, decay channels, and symmetry properties of extended Higgs sectors.

Dr. Logan actively mentors graduate students and has published with numerous advisees, including C. H. de Lima, B. Keeshan, and A. Ismail. She serves on working groups contributing to community reports on Higgs physics and participates in major international conferences including Higgs Couplings workshops, SUSY meetings, and LHC Higgs Cross Section Working Group assemblies. She is currently recruiting graduate students for September 2025 and regularly hosts undergraduate researchers through NSERC programs.

She maintains leadership in inclusivity initiatives, authoring a guide on making research groups more inclusive for autistic trainees (arXiv:2410.17929). Her work appears regularly in leading journals including Physical Review Letters, Physical Review D, and Journal of High Energy Physics, with publications spanning from 2013 to the present.
