- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Caitlin Pepperell, UW Department of Medical Microbiology and Immunology
- Abstract:
Where do pathogens come from? Microbes are all around us, but infectious diseases arise from a tiny fraction of these diverse organisms. Research in my lab is aimed at uncovering the origin stories of pathogenic bacteria: the where, when, how and why of infectious disease emergence. Bacteria occupy incredibly diverse niches and adapt by a multiplicity of mechanisms. Pathogen origin stories reflect this ecological and evolutionary diversity, with our work and others’ showing that there are numerous paths to virulence. This presentation focuses on the origin story of a pathogen I started working on by accident, Staphylococcus saprophyticus. S. saprophyticus, which infects humans and animals, is able to move fluidly among diverse environments. This bacterium illustrates the intertwined ecologies of humans, animals, and the natural and built environments we share. In this presentation, I will share what we have learned about how S. saprophyticus evolved to cause disease. - Host: Clint Sprott

- Physicists at Google
- Time: 2:30 pm - 3:30 pm
- Place: 5310 Chamberlin Hall
- Speaker: Homer Wolfmeister, Google
- Abstract: Running a planet-scale computer requires innovation for delivering storage, data processing, and ML computation at scale. Homer will describe some of Google’s present challenges, and how teams at the Madison office have contributed unique solutions to meet those challenges. He’ll also cover what it’s like to interview for Google, and how research experience in research Physics is valued and applicable to a wide variety of ongoing work at Google.

- Astronomy Colloquium
- Journey: Jets & Outflows Revealing the Nature and Evolution of Massive YSO's"
- Time: 3:00 pm - 5:00 pm
- Place: 4421 Sterling Hall, Coffee and cookies 3:30 PM, Talk begins 3:45 PM
- Speaker: Esteban Araya, Western Illinois
- Abstract: High-mass stars are responsible for some of the most spectacular astronomical objects such as supernova remnants and stellar mass black holes. High-mass stars form in giant molecular clouds, generate copious amounts of ionizing photons responsible for the development of HII regions, and drive ionized jets and massive molecular outflows that contribute to the dissipation of their natal clouds. Highlights of a multi-scale effort by our group to investigate jets and outflows in high-mass star forming regions will be presented. A central component of our work has been student involvement in the search and characterization of atomic and molecular tracers of jets, outflows and the expansion of ionized gas at microwave frequencies. In particular, we are studying molecular masers as tracers of dynamic phenomena in high-mass star forming regions, including long-term variability and periodic flares, which could be indicative of episodic accretion events in young binary systems.
