Our Team

Board of Directors

Corporate policy is to list directors and Science Advisory Board members

Bret T. Barnhizer
Chairman of the Board, CEO, and President

During the past 6 years as CEO of Nanologix, Mr. Barnhizer has worked to further the interests of NanoLogix and to bring its rapid detection technologies to the attention of multiple organizations for their use in combatting infection. Working as part of a small team of like-minded individuals dedicated to this effort, against heavy odds in a field dominated by large well-established corporations, NanoLogix has begun to penetrate the diagnostics market and capture market share. Prior to becoming CEO, Mr. Barnhizer had a successful 25+ year career in the upstream oil and gas industry, working for BP, Chevron, Unocal, Occidental and many others as both consultant and employee, with his last position based in Europe as Manager for European Operations for an independent Canadian oil and gas company.

In his career in the oil and gas industry his innovation and leadership led to the adoption of breakthrough technology applications that are now widely used in the industry. These applications have provided dramatically improved economics and performance in upstream operations with savings to date from 1989 estimated at billions of dollars. Mr. Barnhizer worked as Coastal Sales and Engineering manager for a California oilfield service company and was Vice President for Marketing and Sales for Anacapa Salt & Chemical Inc. Moving from sales and localized engineering into upstream exploration and drilling operations, Mr. Barnhizer provided engineering, project, and operations management services to companies in the U.S., Europe, Africa and Asia, living for extended periods on three continents outside North America. Mr. Barnhizer is a U.S. Army veteran of the Vietnam War, where during his two tours of duty he served as a battlefield combat medic, followed by temporary duty with a USARV Military Advisory Team, providing medical aid and services to Vietnamese civilians as the equivalent of a doctor in four villages and hamlets. Afterwards he managed medical inventory and field resupply for a US Infantry Battalion engaged in active combat, in addition to continued service on Medical Civil Action Programs (MEDCAP) in the Danang area assisting Battalion Surgeons and others in treatment of children in local orphanages. Following the military, Mr. Barnhizer worked in the steel and demolitions industries and then attended Youngstown State University and the University of Colorado, followed by his career in the oil and gas industry.

Mr. Barnhizer is the inventor of the "flatpack" packaging used for the commercial sales of both Nanologix’s BNP and their various petri products. The packaging provides for dramatically extended shelf life and increased efficacy in use for nutrient media used for bacteria detection. He is also the originator of the concept of the use for aptamers in conjunction with Nanologix’s existing patent-pending BNF technology. This concept has led to the filing of a separate patent covering the potential.

Giles Manley, M.D.

Dr. Manley brings to the Science Advisory Board more than 20 years experience in the medical profession. As a Board Certified OB/GYN with well over 2,000 deliveries, he is extremely knowledgeable in all areas of obstetrics. His specialty training was at the Greater Baltimore Medical Center (GBMC), which included a four-month rotation of high risk obstetrics at Johns Hopkins Hospital. Following successful completion of his residency, he served as a faculty instructor at GBMC, as well as maintaining a private practice. In 1996, he left this practice to become the Chief of Obstetrics and Gynecology in Baltimore for the Mid-Atlantic Permanente Medical Group (the physician group of Kaiser Permanente).

He was the first person at GBMC to perform a laparoscopic supra cervical hysterectomy, as was he the first to perform incontinence surgery utilizing a tension free vaginal tape. Both procedures allowed the patient to go home the day of surgery with only a one to two week recovery. He has lectured to physicians nationwide about these innovative techniques.

Throughout his medical career, Dr. Manley has served on a number of committees, including; the Obstetrical Advisory Committee at GBMC, the Gynecology Advisory Committee at GBMC, the Obstetrical Quality Review Committee at Kaiser, to mention a few.
