Science Colloquium

Science Colloquium Lecture Series

Science Colloquium Series is a semester long lecture series that offers everyone in the Linfield community the opportunity to learn about science across the traditional science disciplines of biology, chemistry, math, physics, and computer science. *Made possible in part by generous gifts from the Hearst Foundations. Sponsored by Linfield Physics Department.

Spring Series 2016*

In Partnership with Program for Liberal Arts and Civic Engagement (PLACE) theme: Air, Water, Earth, and Fire: The ancient elements on a changing planet
*NOTE: Day and location varies as the fall lecture series is partnerned with, and builds to, PLACE events. Refreshments will be available starting 15 min prior to events. Additional information on lectures and events will be added as they are scheduled.

Rakshya Khatiwada, University of Washington
"Exploring new forces and particles of nature"
Abstract:Various theories in physics predict the possible existence of new particles in Nature. These particles mediate novel forces that are not part of the Standard Model in physics. This talk will be about some elegant non-accelerator-based techniques that look for these forces and particles, which could solve the long-standing mystery of dark matter among others.
Biography:Rakshya Khatiwada was born in Kathmandu, Nepal. She completed high school at Hermann Gmeiner School, Bhaktapur, Nepal and came all the way to the US by herself to pursue her dream of studying Physics. She graduated from Linfield college with a Physics and Mathematics dual-degree in 2008. She worked at Fermi National Accelerator Laboratory for a year before joining Indiana University where she finished her PhD in experimental Nuclear Physics in 2015. Currently, she is a Research Associate at the University of Washington, Axion Dark Matter eXperiment (ADMX) where she along with other scientists is searching for Axion, a hypothetical particle, which is a promising candidate for cold dark matter.

Rakshya lives in Seattle and enjoys travelling to new places, particularly rich in natural beauty and also is a connoisseur of ethnic, diverse food. She likes to watch unconventional documentaries and movies in her leisure. Fun fact: She is one of the four Physicists in her family (her sister, her spouse and her sister’s spouse).

John Dolan, (chemistry '71), Vice President and Owner, LC Resources
"Who Done It? How Chemical Separations Can Solve Perplexing Problems"
Abstract:Liquid chromatography is a technique used to separate chemicals from each other. It is the most common analytical technique in use today, with applications in forensics, environmental, pharmaceutical, and general chemical laboratories. This seminar will describe the technique and present some practical examples of how it can be used to solve real-world problems.
Biography: Alumni Profile "Circling the globe for science"
John Dolan is a 1970 Linfield graduate with more than 40 years of experience in chromatographic techniques. His company, LC Resources, started an analytical laboratory that began with rented bench space in Murdock Hall and later moved to the McMinnville Industrial Park and grew to more than 25 employees, including several Linfield graduates. He currently provides training services in chromatography for the pharmaceutical industry around the world. He has published >125 technical papers, three books, and >350 monthly installments of his popular “LC Troubleshooting” column in LCGC Magazine.

Susie Crate, Associate Professor of Anthropology in the Department of Environmental Science and Policy at George Mason University
"The Role of Interdisciplinarity in Change Research"
Lecture and discussion of the author's ethnographic work in Siberia, focusing on the importance of interdisciplinary approaches to understanding societal change.  In Siberia, rapid change is underway, due to the twin pressures of climate change and modernization.  Audience members are invited to read Crate's publication, here: (click on ‘view it’**).  As with all Science Colloquia, the lecture and discussion will be understandable to all, whether or not you have had specific training/coursework or a chance to read this work.
***Please note: the Sibirica article ( IS longish; people short on time could focus on the DISCUSSION and CONCLUSION sections (just 7 pages).  Her key general point is that “The practice of ethnography by anthropologists is based on long-term familiarity with the local, an appreciation and understanding of emic perspectives, and a variety of qualitative ways of knowing that privy the researcher in those human aspects.” (p. 68)

Roger Diehl, JPL
"Alien Landscapes: Discoveries from Mars, the Moons of Saturn, and Pluto"
The solar system provides a dazzling array of landscapes that have been captured in recent images from Mars, the moons of Saturn, and Pluto. Dr. Roger Diehl, a volunteer with the NASA Solar System Ambassador Program, will present the latest discoveries from these locations. See images of Martian sand dunes, the methane lakes of Titan, the water ice geysers of Enceladus, and the nitrogen glaciers of Pluto. Also hear about the possibilities of a massive planet located in the far outer solar system beyond the orbit of Pluto.
Biography:In 2014, Dr. Roger Diehl retired after 39 years at the Jet Propulsion Laboratory. During this time at JPL, he made contributions to many missions in the disciplines of mission design and systems engineering. His discovery of the VEEGA trajectory enabled the Galileo spacecraft to be launched to Jupiter after the Challenger accident had ruled out other options. Dr. Diehl also was the Cassini Mission Design Manager, the Shuttle Radar Topography Mission Payload Operations Manager, and Project Systems Engineer for two projects.

Dr. William Fleeger, Linfield College
"Our Annual Crisis: Is U.S Wildfire Policy Sustainable?"
:Currently, 2015 was one of the worst fire seasons on record.  Nationally, over 9 million acres burned and seven lives and over a thousand structures were lost. Suppression costs exceeded $2 billion dollars.   But last year’s fire season is not unique.   According to the National Wildfire Leadership Council, the last two decades have seen a significant escalation of extreme fire behavior, structure and property losses, increased costs, risks to communities and deteriorating conditions on the land.  These trends suggest a need to rethink our response to this annual threat to communities and wildlands in the United States.  This presentation focuses on the historical development and evolution of wildfire policy in the U.S. and the barriers and opportunities for managing the complex and changing wildfire environment.
Biography:William (Bill) Fleeger Ph.D. is a Visiting Senior Scholar in Environmental Policy and Sustainability at Linfield College.  His research has focused on wildfire policy and federal agency and community collaboration in the development of community wildfire protection plans in the American west.  He is a native of southern Oregon and worked for nine years (occasionally as a wildland firefighter) with the U.S. Forest Service
