Our group’s focus, as part of the Center for Vector-Borne Infectious Diseases (CVID), is understanding how RNA viruses replicate at the molecular and biochemical levels in order to develop novel strategies for the prevention and treatment of arboviral diseases. We are also interested in developing novel virus-based tools that can be used by the wider scientific community. We use a wide range of tools (classical virology, molecular biology, cell biology, biochemistry, engineering, computational biology, etc.) to understand how these important human pathogens replicate and use this information to help improve human and animal health.
Dr. Brian Geiss is the Director of the Master of Science in Microbiology – Immunology program. This nine-month, non-thesis program is designed to strengthen the scientific academic portfolio of those seeing terminal professional degrees and provide preparation for those seeking careers in biotechnology and research.
Mechanism of Flavivirus RNA Capping
Mosquito-borne flaviviruses are a continuing public health threat. There are currently few vaccines available against flaviviruses and no antiviral therapeutics available for clinical use. This project will provide insight for the development of new antivirals and vaccines to combat these pathogens.view project
Real Time Monitor for Airborne Viral Pathogens
The Geiss lab and ADev staff have developed carbon-based electrode arrays that are capable of detecting virus particles, a way to modify carbon electrodes with affinity agents that can selectively bind either virus particle simulants and/or virus particles, and a method for integrating working elect.
