I have 13 years of experience and specialize in the field of historical geography with specific knowledge in the area of land markets and values in 18th and 19th century. I have published on such topics as economic development of central New York in the 18th and 19th centuries, gold mining in Costa Rica and the geography of the human immunodeficiency virus epidemic in Thailand, the geography or remittances from Mexican workers in the US. I have testified on pricing the land in early America.
