Mohammad Sajjad Alam

Mohammad Sajjad "Saj" Alam (Bengali: মহম্মদ সাজ্জাদ আলম, ; 5 January 1947 – 4 May 2022 ) was a Pakistani and a naturalized American particle physicist. His work focused on particle physics and computational physics. He played a significant role in several major particle physics experiments (the Mark II, CLEO, GEM, BaBar, ATLAS collaborations) that led to new discoveries in the area of high-energy particle physics.

Early life and family Alam was born to a muhajir family in Dacca, then part of the Bengal Presidency of British India (now Bangladesh), to a family hailing from Calcutta. His family moved to West Pakistan around 1971, after the secession of East Pakistan. Alam was one of eleven siblings: his eldest brother, Muhammad Mahmood Alam (1935 – 2013), was a Pakistani fighter pilot and war hero who rose to the rank of one-star general in the Pakistan Air Force;

Alam decided to become a physicist when his eighth grade science teacher at Saint Gregory High School in Dacca introduced him to atomic and nuclear physics: "I was hooked; I came home and told my father I know that I would become a physicist," he wrote.

He was the first member of his family to come to the United States, and was one of the first Pakistanis to get a PhD in experimental particle physics.

The major experiments that Alam had directed or played a significant role in include:

(1972–1974) SLAC E-82 Searches for Exotic Associated with Mesons Using a Fast Forward Neutron Trigger with the 15" Rapid Cycling Bubble Chamber (1974–75) SLAC E-103 Search for Exotic Mesons Using a Fast Forward Proton Trigger with the SLAC Streamer Chamber (1976–79) MARK II at SPEAR studying collisions. Focus on charm physics (1979–2000) CLEO collaboration (CLEO 1.5, CLEO II), studying collisions at the Cornell Electron Storage Ring (CESR). Focus on charm and beauty physics (1992–1993) Gas Electron Multiplier (GEM) detector proposal for the Superconducting Super Collider (1993–2000) CLEO II Upgrade. Particle Identification System (1995–present) Joined the ATLAS detector pixel group at the Large Hadron Collider, CERN (1998–2000) Nominal member of BTeV at FNAL (2000–present) Joined the BaBar Collaboration

Alam worked with the Beowulf cluster class of supercomputers.

He greatly enjoyed mentoring new physicists, supervising more than twenty PhD students. He was also keenly interested in the relationship between science and religion, and taught a course on the subject.

Honours and awards Dacca University, East Pakistan Overseas Merit Scholarship (1970) Excellence in Research Award by the University at Albany, SUNY (1993) Abdus Salaam Award for Achievements in Science, Pakistan League of America (2000) Fellow, Islamic World Academy of Sciences (2002) Member, Pakistan Academy of Sciences (2003) ISI Highly Cited Researcher in Physics Islamic World Academy of Sciences (2006)
