Dr. Dimitriou is a polymer scientist who specializes in the design, manufacture, and performance of materials used in building and construction, energy generation, automotive, industrial coating, medical, electronic, and consumer product industries. With formulating and materials testing experience on polymer and composite systems, Dr. Dimitriou guides clients in product development, materials selection and processing, patent and trade secret analysis, service life, and failure analysis. 

Dr. Dimitriou's areas of expertise include surface analysis, polymer rheology, chemical, thermal, and mechanical testing of coatings, adhesives, sealants, fibers, non-wovens, rubbers, elastomers, thermoplastics, thermosets, gels, and novel polymer materials. He has research experience defining the structure-property-processing relationships of polymer systems including block copolymers, polymeric surfactants, polymer blends, polymer brushes, confined films, hydrogels, and hierarchical structures.

Dr. Dimitriou has assessed building products including insulation, windows, IGUs, carpet, roofing, flooring, siding, sealants, and caulking from the perspective of design, service life, weathering, and failure analysis. He has addressed issues related to formulation, application, and performance of paints and protective coatings applied to a range of products and substrates. Additionally, he has performed project evaluations of components used in automotive environments, wind and solar energy generation, biomedical, and consumer products. He has direct product development experience using polymer processing techniques such as extrusion, injection molding, and fiber spinning.

Dr. Dimitriou's training and experience is in polymer physics and synthesis, utilizing material design and processing conditions to yield the physical properties of choice for polymer-based applications. He has extensive research, testing and project experience with a variety of thermomechanical [rheology, Dynamic Mechanical Analysis (DMA), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA)], surface characterization [Fourier Transform Infrared (FTIR) spectroscopy, X-ray Photoelectron Spectroscopy (XPS), Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy, surface energy measurements, dynamic Secondary Ion Mass Spectrometry (dSIMS)], macromolecular [Gel Permeation Chromatography (GPC), Nuclear Magnetic Resonance (NMR)], and scattering [Dynamic Light Scattering (DLS), X-ray and neutron scattering, ellipsometry] characterization techniques. He is experienced in methods of polymer coating and thin film deposition including spin coating, spray coating, doctor blade, vapor deposition, and Langmuir-Blodgett deposition.

Prior to joining Exponent, Dr. Dimitriou worked at the National Institute of Standards and Technology's Center for Neutron Research, where he utilized a variety of X-ray and neutron scattering techniques to investigate water uptake in organic sensors and protective coatings, polymer interdiffusion in confined thin films, and antibody interactions at a membrane interface. There he became versed with neutron activation of materials and safe handling protocols. Dr. Dimitriou's doctoral work, funded by the Office of Naval Research, focused on incorporating fluorocarbons (PFAS) into materials to tune surface properties and improve performance. This strategy was used to engineer both an anti-biofouling coating for marine vessels and a lithographic template for patterning in semiconductor manufacturing.
