QAU, Hoodbhoy moved to Lahore where he joined the Lahore University of Management Sciences as a visiting professor, while remaining a visiting scientist at the Stanford Linear Accelerator Center. Controversy over his contract at LUMS sparked an academic debate when it was reported in the news media that Hoodbhoy's email to the Vice-Chancellor of LUMS was made public. Eventually, Hoodbhoy moved to Forman Christian College University permanently and joined the senior staff to instruct courses on physics. Prior to his return to Pakistan in 1976, Hoodbhoy was aware of the country’s secretive development program on nuclear deterrence . Hoodbhoy maintains his close ties with Pakistan's vibrant nuclear society, and had collaborated with many of country's leading theoretical physicists throughout his career, mainly with Ishfaq Ahmad. On several occasions, Hoodbhoy staunchly countered Dr. Abdul Qadeer Khan's "father-of" claims, and roundly criticized his academic research on nuclear physics. In the 1980s, he famously debated with Bashiruddin Mahmood on the topics of sunspots, life-after-death, and philosophy. In 1999, Hoodbhoy with Ishfaq Ahmad and Riazuddin, played a major and influential role in the establishment of the National Center for Physics (NCP), becoming one of the earliest academics and scientists to join the NCP at its inception. Hoodbhoy has roundly criticized the development of nuclear weapons, especially in South Asia, mainly by India and Pakistan. In 2011, Hoodbhoy held India responsible for Pakistan's symmetric nuclear weapons programme as part of Pakistan's self-credible deterrence. According to Hoodbhoy, India's nuclear tests forced Pakistan to jump into the nuclear arena in 1974, and again in 1998, after war-threatening statements were made by the Indian government to Pakistan; Pakistan equalised this situation the same month. While believing that Pakistan's nuclear deterrence has protected the country from any foreign aggression and preventing from numerous war threatening situations with India, Hoodbhoy has raised concerns about the security of nuclear arsenals and the possibility of radicals gaining control. Activism Hoodbhoy is a prominent sponsor of the Bulletin of the Atomic Scientists, representing Pakistan's delegation. Apart from his specialist field of research, Hoodbhoy extensively writes and speaks on topics ranging from science in Islam to education and arms disarmament issues around the world. He is the author of Islam and Science: Religious Orthodoxy and the Battle for Rationality, which has been translated into five languages. In this book, Hoodbhoy outlines the history of Pakistan, the implications of theocracy and martial law in Pakistan,
