U.N.L.V.’s president, Keith E. Whitfield, said on Thursday that Professor Navarro Velez joined the university about five years ago.

She had gotten her Ph.D. in accounting at the University of Central Florida, according to her biography on the U.N.L.V. website.
Professor Chang had taught at the school for more than 20 years after receiving his Ph.D. from the University of Pittsburgh in 2001, according to his résumé. He had completed his undergraduate studies in oceanography at National Taiwan Ocean University.
