Expert 520020 - MD

Expertise Description

I have spent over 25 years working as a Forensic Document Examiner with a particular focus in conducting examinations of domestic and international travel and identification documents to determine authenticity and reveal alterations. My examinations include, but are not limited to, microscopic, Ultraviolet (UV) and Infrared (IR) analysis, instrumental and comparative analysis of handwriting, typewriting, printing processes and stamp impressions. I have additional expertise in the detection of “cut and “paste” signatures in photocopies and nondestructive ink and paper differentiation. I have also spent more than 25 years as a document examiner expert witness in Maryland by providing consultations, deposition, and courtroom testimony.

Expert 518572 - AZ

Expertise Description

I have more than 25 years of experience in Micro-optics and Optical Data Storage. My experience includes photonics, interference, coherence, thin films, multiple-beam interference, various interferometers, the development of rigorous diffraction theory, Fresnel and Fraunhofer diffraction, the optical transfer function, holography and laser speckle, micro-optics for laser diodes and beam shaping, ultraviolet optics, imaging and coherence in microscopy, solid immersion lenses, near-field optics, and advanced physical optics on the nanoscale, with applications in optical data storage, lithography and microscopy. My additional experience includes breaking the “diffraction barrier” by applying the techniques of near-field scanning optical microscopy (NSOM), developing specialized near-field probes, and applying the solid immersion lens (SIL) in various ways and using a SIL-generated evanescent induced polarization signal to obtain topographical, as well as high-resolution reflectivity, information from a surface. I have over 20 years of expert witness experience with consultations, depositions, and courtroom testimony.
