The author is a chemist with a career in the environmental sciences that spans nearly fifty years. He has co-authored dozens of research papers and a book, “Third Century of Biochemical Oxygen Demand”. He also served  on the editorial board for  “Standard Methods for the Examination of Water and Wastewater” for two editions.  He is a lifelong boater, fisherman, diver and avid explorer of Baja. The 'Rebeca Hoffman Files' series evolved from his first novel, ​​​​​​​"The Devil's Trade", connecting the dots between the drug trade in Mexico and Central America, and the international proliferation of illegal arms trading, drug running, money laundering, proxy wars, and imperialism throughout the 20th century. These stories and his subsequent books follow in this vein, depicting the effects of war and international crime on average people who must endure events far outside their control or influence.
