Although trained as a social worker, Haynes entered academia in the 1990s as a graduate professor at the
University of Houston, where she eventually became the first female dean. In 1995, she became the president of the
University of Houston–Victoria. In 2004, she was appointed as president of
California State University San Marcos. She has said she will retire in June 2019. Her 15-year tenure as president is the longest of any president in the 23-campus
California State University (CSU) system. She is also the first woman to serve as president of a CSU campus. Her term began when the university was just fifteen years old and had 7,000 students and seven buildings. During her tenure the university grew to 17,000 students and 22 buildings, plus a satellite campus in
Temecula. More than 100 new academic programs were launched, and the athletic program rose to NCAA Division II status. Haynes made it a focus to attract a diverse student body and to encourage first-generation college students like herself. As of 2018, 45% of the university's students come from traditionally underrepresented demographics, and one-third fall outside the traditional college age range of 18–22. == Selected works ==
