The officers positions for Hydrophiles include: President, Vice President, Treasurer, Secretary, Webmaster, Marys River Watershed Council Representative, and the Symposium Planning Committee Chair. Officers and representatives are elected each year by popular vote of the members. Additionally, as a sponsored student organization the Hydrophiles have a faculty sponsor -- a position which is also determined annually. 

2022-2023 Officers and Advisors

Photo Position Name Information
President Zach Butler

Zach was born and grew up in Bethesda, MD outside of Washington D.C. He got a B.S. in Meteorology and an M.S. in Applied Meteorology before coming to Oregon State to get a PhD in Water Resources Science. Zach is in his second year at OSU where he explores understanding water residence times with stable water isotope tracers. He is passionate about snow-related sciences as well. His hobbies include mushroom foraging, skiing, hiking, camping, and fishing. 

President Michal Tutka Hi. My name is Michal and I come to OSU from Chicago. I'm a second year master's student in WRE and I'm studying large wood hydraulics to better understand how log jams create backwater at a given discharge. I’m especially interested in photogrammetry and particle tracking velocimetry. Estimating discharge from a video? Sign me up!
I like spending my free time playing trivia with friends and consistently losing, woodworking, being barefoot, playing the sax, tending to my plants, attending baptisms, dumpster diving, leaning in extra close to smell the roses, and watching raunchy reality shows with my girlfriend. Streams and rivers energize me.
Vice President Madelyn Maffia

Originating from Santa Rosa, CA, Maddie is a second-year master's student studying Water Resources Science in the College of Forestry. She has a growing interest in restoration projects pertaining to aquatic environments and is currently researching how large wood introductions impact stream geomorphology and coho salmon habitat in the Oregon Coast Range. In her spare time, Maddie enjoys running, hiking, practicing yoga, and lounging near bodies of water.

Treasurer Jordan Jimmie


Jordan is a proud member of the Navajo Nation and comes from Flagstaff, Arizona. He is a third-year Ph.D. student studying Water Resources Engineering and M.S. student in Biological and Ecological Engineering. His work entails characterizing an alluvial aquifer and how the system responds to a managed aquifer recharge project on the lower Toppenish Creek watershed in the Yakama Nation, Washington. He is interested in groundwater systems in the western U.S. and Tribal water law and policy, particularly the adjudication of water for Tribal Nations. In his spare time, Jordan enjoys running and lifting, backpacking, cooking, reading, and angling.

Secretary Hannah Steele

Hannah is a first year PhD student in the geography program studying snow hydrology in the western United States. She is interested in using a variety of geospatial technologies such as remote sensing, machine learning/AI, and GIS to better understand and measure how changing snow conditions impact water resources. She enjoys hiking, playing video games, starting new art projects and generally just hanging out.

Webmaster Sevval Gulduren


Sevval is from Istanbul, Turkey. She is pursuing her masters in Mechanical Engineering and a PhD in Water Resources. She is interested in surface water modeling and is currently working on improving the functionality of sand dams, a type of rainwater harvesting infrastructure built in arid regions. She enjoys playing volleyball (a lot), cycling and hiking. She loves peanut butter and making flyers!


Marys River Watershed Council Representative Dean Jeffrey Anderson

Dean was born and raised on the eastern plains of Colorado but has called Sitka Alaska home for the last 6 years. He obtained a B.S. in Watershed Science and a minor in Geology from Colorado State University and has since worked as a hydrologist on the Tongass National Forest. Dean is a second-year Masters student in Water Resources Science. His research focuses on identifying climate induced changes to the hydrologic and thermal regimes of Alaskan coastal watersheds. In his spare time, Dean loves hanging with his Dog Napali, working with ceramics, and spending time recreating and subsisting in the woods. 

PNW Water Research Symposium Event Coordinator  Laura Duffy Laura grew up in San Jose, CA and studied Political Science and Environmental Studies at Boston College. She is a second year M.S. student in the Water Resources Policy and Management Program and is pursuing a graduate certificate in Water Conflict Management and Transformation at OSU. Her research is focused on social-ecological systems transformation in riverscapes and understanding the barriers and pathways to habitat restoration on private lands. Her hobbies include hiking, knitting, cooking, and gardening.
