In a message from SIU President Randy Dunn, faculty, staff, and students were told of Sarvela's passing Sunday evening.
Dunn says Sarvela's character was one of his greatest strengths.
"As much as we value his many contributions as a mentor and a colleague, it is his friendship and compassion for those around him that we will miss the most."
Sarvela was recently diagnosed with cancer, and although he said the disease would likely change his schedule, the prognosis was good.
He was appointed Interim Chancellor over the summer, filling the position left vacant when former Chancellor Rita Cheng took over as President of Northern Arizona University.
Sarvela's time at the SIU spanned 28 years, ranging from a faculty member to dean, and then Associate Vice President before being named interim Chancellor.
Funeral arrangements and services are pending.
