Focus Group for Workshop Report Out

Below are the members of the Workshop Report Out Focus Group. The report out will be in the form of special section of the Journal of Research of NIST, please see the call for papers on the homepage of the workshop event.

Norman Horn

Dr. Norman Horn is the lead Chemical Engineer at Seal Shield, which manufactures advanced UV disinfection devices for healthcare. He has earned B.S. degrees in Chemical Engineering and Chemistry from the Missouri University of Science and Technology, an M.A. in Theological Studies from the Austin Graduate School of theology, and an M.S. and Ph.D. in Chemical Engineering from the University of Texas at Austin. He also spent a year as a postdoc at MIT in Chemical Engineering, working on projects in flow chemistry and 3D printing. He has won multiple awards for his research and publications, and is published in peer-reviewed journals in three different fields.


Castine Bernardy

Castine Bernardy is a graduate student at the University of New Hampshire. She is studying for her masters of science in Civil and Environmental Engineering. She earned her BS degree in environmental engineering from the University of New Hampshire as well. Castine studies under Dr. Jim Malley, founding president of IUVA. Her masters thesis work focuses on the disinfection of KN-95 face masks using UV-C light. Her interest in this research area was peaked due to the coronavirus pandemic and the need to fill a knowledge gap in the field of surface UV disinfection. Castine is an active member of the IUVA and is the youngest member of the IUVA Covid-19 task force, where she is a young professional for two sub-working groups of the task force. In addition to her work related to UV disinfection, Castine is a teaching assistant for undergraduate students at UNH. She helps Dr. Malley with his responsibilities as a professor and offers academic assistance to students enrolled in her courses.

Troy Cowan

Troy E. Cowan is the owner and founder of Vision Based Consulting, LLC, supporting clients in Federal program development, business development, marketing and regulatory compliance tasks. Troy has worked both in and outside of multiple Government Agencies to include DOE and NNSA, DoD (USAF, DTRA, Army), NASA, HUD, GSA, DHS (FEMA, USCG), as well as several State and Local agencies. While supporting a UV commercial client on regulatory issues, Troy became an advocate for UV-C’s potential to save lives by reducing the risk of Hospital Acquired Infections (HAIs), and the need for standards to demonstrate efficacy to healthcare providers. Over the last five plus years, Troy has met with several Senate and House Committee staffers to promote the development of UV-C efficacy standards, presented to IUVA, SPIE and ISO, organized workshops and panels on using UV-C to combat HAIs, established the IUVA Healthcare/UV Working Group, and has published related articles in the Journals of Infection Control and Hospital Epidemiology, the SPIE Journal and UV Solutions on this critical issue.

Michael Postek

Dr. Michael T. Postek is an Assistant Professor at the University of South Florida. He is an internationally recognized expert in nanometrology with emphasis on SEM and semiconductor CD. Previously, Dr. Postek was the Chief of the Precision Engineering Division at NIST where he led research and measurement service programs in dimensional metrology. He also served as the National Program Manager for the Nanomanufacturing Program in the Manufacturing Engineering Laboratory and retired as a senior scientist in the Engineering Physics Division of the Physical Measurement Laboratory. He developed and taught microscopy short courses at the University of Maryland for over 14 years and more recently at the University of Hartford and with Hitachi High Technologies America. Dr. Postek holds over 300 publications and authorship of the book “Scanning Electron Microscopy – A Student Handbook” in addition to being a recognized Fellow for both the SPIE and MSA societies.

Dianne Poster

Dr. Dianne L. Poster is a Senior Advisor at the U.S. National Institute of Standards and Technology (NIST) within the Director’s Office of the Materials Measurement Laboratory. Dr. Poster supports scientific programs in emerging measurements, standards, technology, and data. In a prior assignment, as Deputy Associate Director for Technology and Environmental Policy at the White House Council on Environmental Quality, Dr. Poster administered the environmental federal regulatory portfolio and advised on policy and strategy issues related to protecting the environment.
