Manager's Bio

Rosanna Thurman
Principal Investigator

Rosanna Thurman is Honua’s principle investigator under our SHPD Permit.  She has a master’s degree in applied archaeology from the University of Hawaii at Manoa.  She has previously worked as an archaeologist for the Illinois Transportation Archaeological Research Project (ITARP) and the Missouri Department of Transportation (MoDot).  In addition, Rosanna has long been an avid sailor and traveled throughout many of the world's oceans and seas. Her passion for Hawaiian archaeology led her to the shores of Oʻahu, where she has resided since 2007.   Since her move to Hawaiʻi in 2007, Rosanna has led numerous successful projects across the state and joined Honua in 2014.

In addition to working with Honua, Rosanna also runs her own archaeological firm, Oceanic Archaeological Science and Educational Services (OASES). OASES focuses on community-based archaeological projects where documented sites are preserved and maintained by training individuals and groups in using best conservation practices.  She is supported by trained archaeologist, husband and on-call Honua employee, Douglas Thurman.
