Legal Experience & Services
Gossman Forensics has the technical background and the needed communication skills to explain the science behind what happened and the real-life operational experience to explain why it happened. Incidents that prompt litigation does not just happen, they occur as the result of a string of decisions that can date back to the initial facility design. Incidents may occur as a result of poorly designed or executed; maintenance procedures, hiring and training practices, laboratory procedures, sales and marketing strategies, etc. all of which require operational expertise to evaluate. Even a badly written regulation may contribute to the eventual incident. Clearly, the experience and expertise of Gossman Forensics can be a valuable aid in preparing for litigation.

Articles Published by Gossman Forensics
Forensic Investigations and Odors
Our sense of smell is alerted when molecules of a particular odorous substance travel into the nose. Receptor cells within the nasal cavity become stimulated and take hold of the odor molecules. The interaction generates electrical signals, which are shuttled to the brain by nerve cells. The brain perceives odors and often accesses memories to remind us about people, events and places associated with the sensations.Read Article
