Humanitarian volunteer work

Since 2013 I have been helping refugees from Ivory Coast and Liberian civil wars re-establish themselves.  Initially I rent apartments for refugees, purchase land, build cinder block homes, help them repatriate, find gainful employment, and farm on the land I give them.  Refugees who cannot repatriate I help relocate to permanent new lives through UN programs.  November 2015 my efforts became a registered Liberian NGO called Hope For Tomorrow.  Thus far I have helped many hundreds of refugees.

Co-founder of the WordTree Foundation,  Working on algorithms to enable scientific textual analysis (e.g. n-gram) of literary works to shed light on provenance, and external influence, especially for works written prior to the modern age, which will shed light on how human thought has evolved.  All code is open source:

I contribute on an ongoing basis to the following charities:

        United Way                Africa Heartwood Project        Hope For Tomorrow

        Children International                      Heifer International
