Mr. Jeka has a diverse background in materials evaluation and characterization, with areas of expertise  in optical microscopy and scanning electron microscopy (SEM) and failure analysis.   He has  experience managing materials failure analysis projects and extensive hands-on experience in litigation and laboratory support.

Prior to that, Mr. Jeka was working with Packer Engineering in Naperville IL, as an adjunct consultant with the materials department and industrial services group,  while performing contract work as an electron microscopist at BP Amoco, Inorganic Materials Characterization, Microscopy and Microanalysis, North America Analytical Sciences Group in Naperville, IL.   At BP, his responsibilities involved providing in-house failure analysis, microscopy and microanalysis services for root cause and corrective action associated with purified terephthalic acid, fuels, and oil refinery production processes.  Associated material characterization included metals, metal oxides, polymers, catalysts, contaminants and corrosion products. 

 In addition, Mr. Jeka has consulted on a legal case providing his expertise regarding interpretation of an EDS analysis related to subject evidence involving suspected contaminants on a disposable cigarette lighter.   He has an extensive background in inspection, failure analysis and product testing in this area.  Also, Mr. Jeka has consulted on a failure analysis case related to insulated glass window units with Polyisobutylene adhesive.

Mr. Jeka was employed as a project manager, failure analyst  and  microscopist involved in materials evaluation for over twenty years at L. J. Broutman & Associates / Bodycote Testing Group until the laboratory was closed in July of 2008.  He has worked on hundreds of failure analysis cases involving consumer products, insurance claims, industrial projects, and legal cases, including patent issues.  He has co-authored technical papers on polymers used for implants and another on anisotropy of thermoplastic elastomers.  Prior to working at the Broutman laboratory, Mr. Jeka had nearly a fifteen-year work history at IIT Research Institute in the Mechanics of Materials division where he worked in the laboratory characterizing ceramic materials for high temperature turbine engine applications and performing research on building materials, including experimental concrete, marble cladding, admixtures and soils.

Mr. Jeka has been involved in technical investigations and failure analyses that required the use of many laboratory analysis techniques including; optical microscopy with digital image analysis, fractography, scanning electron microscopy, elemental analysis, non-destructive evaluation, custom testing, fixture design, metallurgical sample preparation, data acquisition, strain gauging, residual stress measurement, field and laboratory inspection, evidence inspection and documentation, flammability, material testing and chemical analysis.
