Paul W. Gabrielson
(b. 19 November 1952)

I earned my Ph.D. from the University of North Carolina at Chapel Hill in 1980 and spent the next two decades doing research on algae and teaching at a small liberal arts college.  I am back to where I started as a graduate student -- doing algal systematics (but now with a molecular twist) in Chapel Hill.

Teaching the summer Marine Botany course intermittently over the past 15 years at the Friday Harbor Labs (FHL), University of Washington's marine lab on San Juan Island in northern Puget Sound, has shaped my career and has resulted in publications used by students and professionals to identity marine algae.  Two of the most recent are:
 
Keys to the Seaweeds and Seagrasses of Oregon and California, North of Point Conception (2004) by Paul W. Gabrielson, Thomas Benjamin Widdowson and Susan C. Lindstrom

and

Keys to the Seaweeds and Seagrasses of Southeast Alaska, British Columbia, Washington and Oregon (2012) by Paul W. Gabrielson, Susan C. Lindstrom and Charles J. O’Kelly.

Currently, I am obtaining molecular fingerprints from recent field-collected specimens to compare with those obtained from type specimens, many dating from the 19th Century. This ability to unequivocally match type and historically important collections with recently collected specimens allows us to explore a host of questions that hitherto have been difficult to answer. For example: Are names of seaweeds with type localities outside of the Northeast Pacific correctly applied to local species? What are the biogeographic limits of morphologically similar species? the ecological limits? Are invasive species present that are morphologically similar to native species?
