Phys. Rev. Lett. 115 (2015) 021301
Provides the first calculable realization of the SIMP mechanism using a QCD-like hidden sector where pseudo-Nambu-Goldstone bosons are the dark matter and the Wess-Zumino-Witten term mediates the 3-to-2 number-changing process.
Phys. Rev. Lett. 113 (2014) 171301
Introduces the SIMP paradigm in which the thermal relic abundance is set by 3-to-2 self-annihilations in a hidden sector that remains in kinetic equilibrium with the Standard Model. Predicts light (MeV-GeV) dark matter with sizable self-interactions.

Studies the connection between the top Yukawa coupling and dark matter, exploring how the Higgs-top interaction constrains and motivates dark sector models.
JHEP 09 (2013) 061
Provides a complete map of the CMSSM parameter space consistent with the Higgs mass and dark matter abundance, organizing viable regions by dark matter mechanism and presenting benchmark models with their 13 TeV LHC signatures.
JHEP 10 (2012) 134
Uses Fermi-LAT data below 5 GeV from the inner Galaxy to constrain the ratio of continuum to monochromatic photons from dark matter annihilation, excluding neutralino dark matter as an explanation for the reported 130 GeV gamma-ray line.
JHEP 03 (2016) 149
Proposes a method to extract the local dark matter phase-space distribution from directional detection data, decomposing the distribution function in moments of a model-independent basis and showing that O(1000) events can measure deviations from the Standard Halo Model.
Adv. High Energy Phys. 2011 (2011) 709492
Proposes a class of supersymmetric composite dark matter models where Standard Model interactions communicate SUSY breaking to the dark sector, computing the bound state spectrum with leading supersymmetry effects using a general formalism independent of binding dynamics.
Phys. Rev. D 82 (2010) 031901
Assesses the prospects for upcoming direct detection experiments to test the inelastic dark matter interpretation of the DAMA signal, identifying the experimental benchmarks needed to confirm or exclude the scenario.
JHEP 1006:113 (2010)
Works out the early-universe cosmology of composite inelastic dark matter, including the synthesis of constituent quarks into dark mesons and baryons, finding qualitatively different configurations depending on the mass hierarchy of the hidden sector.
J. Math. Phys. 52 (2011) 062102
Studies the spectrum of supersymmetric bound states, computing degeneracies in supersymmetric hydrogen and emphasizing the general features of non-relativistic supersymmetric bound state systems.
Phys. Rev. D 82 (2010) 055023
Shows that higher-dimensional operators in composite inelastic dark matter introduce parity violation, creating an admixture of inelastic and elastic scattering channels consistent with direct detection experiments even at near-maximal parity violation.
Phys. Rev. D 81 (2010) 096005
Shows how directional dark matter detectors can distinguish between different dark matter scattering dynamics, including elastic, inelastic, and momentum-dependent interactions.
Phys. Lett. B 692 (2010) 323-326
Proposes that the DAMA annual modulation signal arises from hyperfine transitions of composite dark matter, a meson from a QCD-like hidden sector whose spin-spin interactions produce the O(100 keV) mass splitting required for inelastic scattering.

Explores gauge coupling unification and dark matter in a minimal extension of the Standard Model with additional scalar fields, studying the interplay between unification constraints and the dark matter relic density.
Phys. Rev. D 69:065022 (2004)
Investigates the scalar dark matter candidate in the Little Higgs theory-space model, performing a thermal relic density calculation and finding two viable mass regions — around 100 GeV and above 500 GeV — where the dark matter is an admixture of SU(2) triplet and singlet.
JHEP 0208:020 (2002)
Works out the collider phenomenology and dark matter implications of the Little Higgs mechanism, predicting light Higgs doublets accompanied by new weak triplet and singlet scalars, heavy TeV-scale particles with distinctive decay signatures, and a new WIMP dark matter candidate from a discrete geometric symmetry.
