Zika: The Origins and Transmission of a Virus

With Dan Streblow, PhD, Associate Scientist at the Vaccine and Gene Therapy Institute and Research Assistant Professor at the Department of Molecular Microbiology and Immunology at Oregon Health & Science University, and Christopher M. Wirth, Program Manager for the Multnomah County Health Department's Vector Control and Enforcement Program

Doors Open @ 5PM | $5 Suggested Donation

Zika virus (ZIKV), a mosquito-borne flavivirus closely related to yellow fever and dengue viruses, is currently causing a large outbreak in the Americas. Recently, local spread occurred in Miami, Florida highlighting the ability of the virus to take hold in the United States. Historically, ZIKV was considered sporadic and causing relatively mild disease. However, current observations with this recent outbreak indicate ZIKV causes neurological sequelae in adults, such as Guillian-Barré Syndrome and devastating neurological birth defects such as microcephaly in the developing fetus. The possible association of ZIKV with microcephaly in newborns and other neurological disorders precipitated the World Health Organization (WHO) to declare the outbreak of microcephaly-associated ZIKV a Public Health Emergency of International concern.


In this talk, virologist Dr. Streblow will discuss the origins of ZIKV, routes of transmission, the recent worsening of pathogenesis in adults and neonates as well as current efforts aimed at eradicating the virus. For a local perspective, Christopher Wirth will discuss mosquito control in Multnomah County and what species of mosquito are of concern related to Zika and other diseases in our region.


Daniel Streblow, Ph.D. is a virologist specializing in viral pathogenesis. He graduated from the University of Wisconsin-Madison where he trained in the field of HIV pathogenesis. His lab currently focuses on the study of viral pathogenesis and disease by defining host:virus relationships at the whole organism level to the cellular/molecular level. The lab works on a number of different viruses including cytomegalovirus, Chikungunya virus, and Zika virus.


Christopher M. Wirth is the Program Manager for the Multnomah County Health Department's Vector Control and Enforcement program, which serves to protect the public from vector-borne disease. Vector Control protects health and enhances livability through control of the rat and mosquito populations, and serves as a resource for addressing public health vector problems. Programs include Rodent Control, Mosquito Control and Code Enforcement, which enforces some specific county and city municipal codes. Vector control is focused on maintaining mosquito populations at levels that are safe and comfortable for the residents of Multnomah County. Christopher Wirth's position is involved with numerous regulations and health concerns and involves supervision of the Department’s response to disease outbreaks, natural disaster and other public health vector and nuisance related hazards. Chris has a Biology degree from University of Colorado, Boulder. 


Dinner and drinks will be available throughout the presentation. Please see the Mission Theater website for a dinner menu and venue information.

Science Pub Eugene: Nanotechnology

Nanotechnology: Breakthroughs Enabled by Making Things Small

With David Johnson, PhD, Professor of Chemistry and Rosaria P. Haugland Foundation Chair in Pure and Applied Chemistry at the University of Oregon

Doors open @ 5PM | $5 Suggested Donation

Imagine taking gold metal and clear glass and performing alchemy to make them turn into a brilliant red colored stained glass.  This and similar transformations were the basis of trade secrets in the middle ages making stained glass. We now know that the only transformation involved is dividing the gold (or other metal) into nano-sized particles dispersed throughout the glass.


In this talk, materials scientist David Johnson will describe why the properties of materials change as size is decreased to the nanoscale and why nanoscience and nanotechnology has created such intense interest around the world. New technologies in the market place will be discussed.


David received his Ph.D. from Cornell in 1983 and worked as a research chemist for DuPont before coming to Oregon in 1986, where he received the Oregon Academy of Science’s Outstanding Scientist Award in 2006.  He has served as a Board Member for the International Thermoelectric Society and is a founding academic member of the Oregon Nanoscience and Microtechnology Institute (ONAMI). He was a Mercator Fellow of the DFG (the German Research Foundation) in 2013 at the University of Freiburg.

He is currently the Rosaria Haugland Foundation Chair in Pure and Applied Chemistry at the University of Oregon. He helped create the Graduate Internship Program and the Center for Advanced Materials Characterization in Oregon (CAMCOR) – the state of Oregon’s ‘high tech’ extension service,


Johnson’s research is at the interface of chemistry and physics focused on controlling materials properties using nanoarchitecture.  His non-traditional approach to chemical synthesis has led to many new materials with unprecedented physical properties.  A recent example is the discovery of a new class of materials with the lowest thermal conductivity ever reported for a fully dense solid.
