Geiss Lab

Our group’s focus, as part of the Center for Vector-Borne Infectious Diseases (CVID), is to understand 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.

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.

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.
