College Professor at the Department of Physics and Astronomy, Okanagan College. I maintain an active research program in high-energy physics phenomenology as part of the MoEDAL-MAPP Collaboration. My work combines problem-solving, computational modeling, and scientific investigation expertise with a passion for teaching and effective scientific communication. I am interested in collider phenomenology, searches for new physics beyond the Standard Model, and studies of electromagnetic interactions with biological systems.
Studies of the unique signatures of highly ionizing particles (e.g., magnetic monopoles) and feebly interacting particles (e.g., dark photons) as avatars of new physics and the sensitivity of new experiments to such signatures.
Dedicated experiments at high-energy colliders for new physics searches, such as the recently approved MoEDAL-MAPP experiment at the LHC.
Studies of electromagnetic interactions with biological systems—typically experiments involving cells and/or cellular components such as microtubules.
Student learning of quantum mechanics (QM) and visual QM for the classroom.

Electrically charged particles can be created by the decay of strong enough electric fields, a phenomenon known as the Schwinger mechanism. By electromagnetic duality, a sufficiently strong magnetic field would similarly produce magnetic monopoles, if they exist. Here we present a search for magnetic monopole production by the Schwinger mechanism in Pb–Pb heavy ion collisions at the Large Hadron Collider, producing the strongest known magnetic fields in the current Universe.
In this paper, we use a straightforward numerical method to solve scattering models in one-dimensional lattices based on a tight-binding band structure. We do this by using the wave packet approach to scattering, which presents a more intuitive physical picture than the traditional plane wave approach.
The MoEDAL trapping detector consists of approximately 800 kg of aluminum volumes. It was exposed during run 2 of the LHC program to 6.46 inverse femtobarns of 13 TeV proton–proton collisions at the LHCb interaction point. Evidence for dyons (particles with electric and magnetic charge) captured in the trapping detector was sought by passing the aluminum volumes comprising the detector through a superconducting quantum interference device (SQUID) magnetometer.
We present a strategy for searching for heavy neutrinos at the Large Hadron Collider using the MoEDAL Experiment's MAPP detector. We hypothesize the heavy neutrino to be a member of a fourth generation lepton doublet, with the electric dipole moment (EDM) introduced within a dimension-five operator.
MoEDAL is designed to identify new physics in the form of stable or pseudostable highly ionizing particles produced in high-energy Large Hadron Collider (LHC) collisions. Here we update our previous search for magnetic monopoles in Run 2 using the full trapping detector with almost four times more material and almost twice more integrated luminosity.
In this paper, we calculate the dipole–dipole interaction energy between tubulin dimers in a microtubule as part of the various contributions to the energy balance. We also compare the remaining contributions to the interaction energies between tubulin dimers and establish a balance between stabilizing and destabilizing components, including the van der Waals, electrostatic, and solvent-accessible surface area energies.
