We engage the Portland, Oregon scientific and technical community to enhance the health of the scientific research enterprise, provide opportunities for the next generation of scientists and engineers, and promote the public's understanding of science and technology. We are comprised of faculty and students from several colleges and universities in the Portland area, as well as colleagues in local business, industry, federal and state agencies, and medical centers. We focus many of our programs on enhancing the experiences of students at all levels. Many of our members are retired scientists and engineers who have relocated to the Portland area and find a community of interests through the activities of the chapter.

Chapter winetasting/geology trip, with Scott Burns
Willamina region (McMinnville AVA)
Friday 14 Aug, 10 am - 6 pm
Chapter members and guests visited three wineries (Anne Amie, Yamhill Valley, and Maysara) and learned their history and the geology of their soils. The trip also visited the Bellevue glacial erratic, deposited on a hill in Yamhill County by the earliest and largest of 40 Missoula floods that inundated the Willamette Valley near the end of the Pleistocene glaciation.

Jessica Hebert (Portland State University, Biology) won both the overall best (poster and oral) cell and molecular biology section award, and the overall conference best poster award, at the AAAS Pacific Division conference, 14-17 June 2015. The conference, at San Francisco State University, was co-sponsored by Sigma Xi's Northwest and Southwest Regions. There were 106 student presentations.

Back in April, Jessica's poster, Increased maternal angiotensinogen expression and male fetal gender affect placental size and capillary density, earned a first-place award in the biomedical science and cell biology category at the Sigma Xi Columbia-Willamette Student Research Symposium. The C-W Chapter provided partial travel support to enable her to attend the June conference.
