Team Assured Bio


Dr. Edward Sobek


Dr. Sobek specializes in microbial and chemical issues affecting the built-environment. He and his team at Assured Bio Labs have tackled everything from viral outbreaks in medical facilities, moldy manufactured plastics, Legionella investigations to formaldehyde off-gassing in building materials. They have diagnosed mold and bacteria issues in hundreds of homes, commercial properties and complex manufacturing settings. He has worked on odor and chemical contamination in both residential and commercial properties.  Dr. Sobek’s ability to identify the root cause of contamination truly sets him apart as an outstanding problem solver.

He has examined years of historical microbiological data and the results indicate a major flaw with current detection technologies that completely miss or grossly underestimate the true concentrations of microbes in the built environment. Hence, his insight and mastery of microbial DNA analysis and microbial ecology is vital for a successful project outcome. That and his relentless pursuit of scientific solutions are the distinguishing factors sought by the companies that engage his services.

Dr. Sobek is a PhD microbiologist with 20 years of laboratory and field experience. His vision is to develop industry standards with DNA based diagnostics to replace antiquated technologies that often stymie the microbial investigation process. In order to achieve those aims, he has become an avid entrepreneur and inventor. He invented the novel microbial detection technology called Molecular Entrapment, which he branded into the M-TRAP® air sampler that is a CDC/NIOSH verified technology to capture airborne influenza virus and airborne Legionella pneumophila.
