Ian Davidson

Ian Davidson
Ph: 503-725-2923

PhD: University College Cork, Ireland • Marine Biology
BSc: University College Cork, Ireland • Applied Ecology

Ian is a Research Associate at the Aquatic Bioinvasion Research & Policy Institute. He has been working atPSU since 2004 and has a BSc in Applied Ecology and PhD in Marine Ecology from University College Cork, Ireland. His research focuses on marine and estuarine introduced species and benthic ecology. He works with colleagues at the Marine Invasions Lab of the Smithsonian Environmental Research Center on maritime vectors of invasive species, especially vessel biofouling. This work has included research projects undertaken from Panama to Alaska and from Micronesia to the East Coast of North America. He also works on ballast water, marine biodiversity, biogeography, eradication and control of
invaders, and management & policy related to introductions.


Robyn Draheim

Robyn Draheim

Ph: 503.725.4994

MMA: UW School of Marine Affairs • Marine Policy and Resource Management
MS: VIMS/College of William and Mary • Marine Biology
BS: UCLA • Marine Biology

Robyn Draheim is a research assistant with the Center for Lakes and Reservoirs. Her background is in benthic ecology and estuarine systems and she has been involved with invasive species issues since 1997. She coordinated the Middle Columbia River Aquatic Nonindigenous Species Survey (an extension of a similar project on the Lower Columbia River summarized here) and assists with the implementation of the Oregon ANS Management Plan. She also provides education and outreach on Mitten crabs, New Zealand mudsnails, etc.

Vanessa Howard Morgan

Vanessa Miller
Ph: 503.725.2937

B.A Community Studies • UC Santa Cruz

Vanessa is a Research Assistant with the Center for Lakes and Reservoirs. She works on early-detection surveys for both freshwater and estuarine macrophytes, fields questions on aquatic plant identification and management options, and assists with education and outreach efforts regarding AIS issues. Vanessa conducted research to determine the potential geographic spread of Spartina spp. propagules via ocean currents and to better understand the vegetative reproductive capacity of Spartina alterniflora.  Previous projects have included helping maintain the plant portion of the USGS Nonindigenous Aquatic Species database, tailoring a field guide of aquatic plants for use in Alaska, writing the 'Alaska Spartina Prevention, Detection and Response Plan' (2010), and coordinating AIS surveys in western Wyoming. 

Rich Miller

Rich Miller
Ph: 503.725.9075

BS:Humboldt State University • Aquatic Systems Analysis

Rich Miller is a research assistant for the Center for Lakes and Reservoirs. Rich’s technical expertise lies in water quality monitoring, invasive species surveys, bathymetric and aquatic plant mapping, and data management. His research interests include nutrient loading, food web ecology, harmful algal blooms, and aquatic invasive plants. He has
contributed to many projects including the ecological monitoring of Diamond Lake and Waldo Lake, Oregon. He recently helped develop the on-line Atlas of Oregon Lakes and is working on a volunteer lake monitoring pilot project. In addition to
his duties as a technician, Rich is pursuing a MS degree with a thesis project focused on modeling the distributions of aquatic macrophytes within lakes.

Steve Wells
Ph: 503.725.9075
Fax: 503.725.3834

BS:Environmental Sciences- Biology • Marist College

MS: Environmental Sciences • Portland State University

Steve is a Research Assistant with the Center for Lakes and Reservoirs. He researched the phenology of Potamogeton crispus, curlyleaf pondweed, for his graduate studies and currently works with zebra (Dreissena polymorpha) and quagga (Dreissena r. burgensis) mussels. His work involves coordinating the Portland State University Zebra and Quagga Mussel Monitoring Program, public outreach and education, and research regarding mussel biology and control.
