Dr. Allen is a trained chemical engineer and polymer scientist who utilizes his expertise in polymer mechanics, photo-curing, and materials characterization to consult on complicated projects related to failure analysis and optimization of elastomer, plastic, and adhesive products. He frequently consults for clients in industries including consumer electronics, medical devices, and automation. Dr. Allen's professional interests focus on the analysis and optimization of polymer products for improved reliability and performance.

Dr. Allen has widespread experience in characterization of polymer materials including dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), rheology, Fourier transformed infrared spectroscopy (FTIR), real-time reaction monitoring (RT-FTIR), tensile and fracture testing of polymers, gel permeation chromatography (GPC), nuclear magnetic resonance spectroscopy (NMR), X-ray scattering (SAXS), as well as a range of spectroscopic and elemental analyses.

Before joining Ģ��tv, Dr. Allen completed his Ph.D. in Chemical Engineering at the University of Texas at Austin where he was a National Science Foundation graduate research fellow. His research focused on developing novel light-based methods for control and patterning of mechanical properties in polymer materials. Through his research, he developed a robust knowledge of polymer mechanics and characterization, light-based 3D-printing, and membrane materials.
