University of HartfordUnited States

Brian Wells serves as Associate Professor of Physics in the College of Arts and Sciences at the University of Hartford, with research spanning computational photonics and low-dimensional magnetic systems. His collaborative work bridges theoretical modeling and practical undergraduate-accessible experimentation. Education PhD, University of Massachusetts, Lowell MS, University of Massachusetts, Lowell BS, Clark University Professor Wells' research bifurcates into two synergistic domains. His photonics work develops theories and numerical simulations for optical metamaterials—particularly plasmonic nanowire assemblies—using MATLAB and Finite Element Method software, while establishing an undergraduate-focused lab for microwave-scale metamaterials fabrication via silk-screen printing. This enables investigations into cloaking, negatively indexed materials, and super-lensing. Concurrently, he studies spin-spin interactions in frustrated magnetic systems using ALPS simulation codes and MATLAB, comparing results with quantum Monte Carlo data and experimental validation from Clark University's magneto-Chemistry group. His publication trajectory reveals a strategic evolution: early work (2005-2009) centered on quantum magnetic systems in copper compounds, while recent publications (2013-2017) demonstrate deep engagement with nonlocal effects in metamaterials, plasmonic waveguide dynamics, and spontaneous emission phenomena—showcasing consistent application of computational physics across domains. No scientific awards were documented in available sources. Professor Wells' lab development indicates active research funding, though specific grants aren't detailed. His collaborations with UMass Lowell and Clark University enhance resource access, while the microwave metamaterials approach creates exceptional undergraduate research opportunities—students participate in full experimental cycles from fabrication to validation, gaining skills typically reserved for graduate programs. The emerging microwave metamaterials lab utilizes conductive ink and traditional printing techniques to democratize advanced research, allowing students to investigate cloaking mechanisms and super-lensing effects through hands-on experimentation. This practical framework transforms theoretical concepts into tangible learning experiences while advancing frontier research in accessible ways.
