CONCORD — Severine Wamala, the former Math Department chairman at Lowell High School, who was released early from prison after being convicted of 11 counts of aggravated rape for years of abuse against his daughter, has been denied permission to travel overseas.

Wamala, 63, a naturalized U.S. citizen who was living in Nashua, New Hampshire at the time of his conviction, was granted parole in 2021 after being sentenced in 2007 to 20 to 40 years in prison. Wamala appeared before the New Hampshire Parole Board on Thursday, requesting permission to travel to his native Uganda for the last rites and rituals of his father, who he said died in 2007.
