Research & Technical Contributions

Leading high-precision investigations into weak axial-vector coupling (\(g_A\)) quenching and nuclear matrix elements, with a dedicated focus on small nuclear matrix elements (sNME). A central pillar of my research is the exact theoretical generation and distribution of beta spectral shapes for selected isotopes, pushing the worldwide frontier in forbidden non-unique cases. While these advanced theoretical frameworks have broad implications for rare-event physics such as neutrinoless double-beta decay (\(0\nu\beta\beta\)) experiments and nuclear reactor decay heat calculations, my primary focus remains mastering the complex nuclear many-body dynamics governing forbidden non-unique transitions.

In deep underground liquid xenon time projection chambers (TPCs), natural underground earth radiation originating from the radon chain (specifically ²¹⁴Pb) represents an irreducible background. Crucially, ²¹⁴Pb undergoes a first-forbidden non-unique beta decay, connecting directly back to my primary theoretical focus. I provide exact theoretical derivations of these complex spectral shapes to establish highly accurate background models. This precise modelling is essential for international collaborations to calibrate out natural earth radiation when searching for rare events.

A core future direction of my research is translating the exact theoretical methodologies established in Pillars 1 and 2 directly into clinical medical physics. In targeted radionuclide therapy, standard dosimetry models frequently rely on default approximations that render the calculated beta spectra of therapeutic isotopes like ¹⁷⁷Lu inaccurate. To bridge this gap, my preliminary research on ⁶⁷Cu demonstrated that implementing even subtle theoretical refinements, specifically the allowed exchange correction, produces a quantifiable difference in voxel-level Geant4 dosimetry. This foundational proof-of-concept drives my active vision for clinical translation.
