Prior to his appointment as President of the George Washington University, LeBlanc served as the University of Miami's Chief Academic Officer, Chief Budget Officer, Executive Vice-president, and Provost. While at the University of Miami, LeBlanc led the development and implementation of the university's strategic plan. He served as interim President of the University of Miami in 2015.

Prior to Miami, LeBlanc served as Vice Provost & Dean of the Faculty of Arts, Sciences, and Engineering at the University of Rochester. He was chair of the department of computer science and the Dean of the College Faculty. He is credited with the development of the biomedical engineering department with the University of Rochester Medical Center.^[3]

In May 2021, LeBlanc said he would retire from his position at GWU at the end of the 2021–2022 academic year.^[4] However, in September 2021, GWU's Board of Trustees Chair Grace E. Speights said LeBlanc would step down at the end of 2021, to be replaced by former Washington University in St. Louis Chancellor Mark S. Wrighton on an interim basis while a search is being conducted for a permanent replacement.^[5]

On February 1, 2020, a video was posted to the George Washington University Overheard Facebook page where a freshman at the university, Sophie Gengler, asked President LeBlanc about divestment from fossil fuels.^[6] In the video, LeBlanc admitted for the first time that 3% of the university's endowment is indirectly invested in the fossil fuels industry through buying funds that invest in "whatever they want to invest in" which includes the carbon industry. This, along with other points the president made about the university's relationship with climate change activism and deniers, sparked a student protest and several petitions demanding for the university to divest immediately.^{[citation needed]}

In the same video, LeBlanc criticized majority rule over GW policy by saying, "What if the majority of the students agreed to shoot all the black people here?"^[6] Students quickly condemned the president's comments as "racially insensitive" and "thoughtless."^[7] The president later apologized, saying "The point I was making – that majority rule should never suppress the human rights of others – was obscured by the example I used...I regret my choice of words and any harm I unintentionally inflicted on a community I value greatly."^[7]
