Matt Ciaschini joined Prudential Financial's mortgage capital unit in San Francisco as chief investment officer for agricultural equity, a Prudential news release said.
Mr. Ciaschini was a vice president, natural resources, at Harvard Management Co., where he helped to oversee a portfolio of $700 million.
HMC does not plan to replace Mr. Ciaschini; his responsibilities have been absorbed by the rest of the natural resource investments team, said someone with knowledge of the matter who asked not to be named.
HMC oversees the $32.7 billion endowment for Harvard University.
