My career interests lie within the broad fields of bedrock mapping and mineral exploration, particularly in magmatic-hydrothermal settings. Upon completion of my Ph.D. studies (March 2013), I would like to combine detailed bedrock mapping with research studies (geochemical, geochronological, and/or isotopic) that will add value to mineral exploration and regional mapping programs. 


Past and current experiences have taught about planning and running field and research programs, paper and digital mapping techniques from regional- to showing-scales, and safety and competency working in remote or mountainous regions. Through previous jobs, short courses, and field trips to local and international mining districts, I have had the opportunity to learn about (and in many cases see) different geological settings and styles of mineralization. I am an active member of the geological community, as is demonstrated by my publications, presentations, professional memberships, and volunteer experience.
