Joefon Jann has been recognized by Marquis Who’s Who Top Scientists for dedication, achievements, and leadership in computer science.

Since 1989, Ms. Jann has contributed her skills and expertise as a computer scientist at the T.J. Watson Research Center for IBM. She has a longstanding history of working for IBM, having previously been a member of the technical staff of the company’s Mathematics Analysis & Computation Center, an advanced system engineer of the New York Banking Branch Office, and as a systems and APL programmer at their ISTG Headquarters. Furthermore, Ms. Jann has earlier experience as a technical staff member of the Network Analysis Corporation and as an adjunct lecturer in mathematics for Lehman College.

Growing up, Ms. Jann had a natural talent in mathematics and soon found that she could take her skills further by applying them to computer science. She first earned a bachelor’s degree in mathematics at Wellesley College in 1970 and carried on her education at the City University of New York to receive a master’s in mathematics in 1972. She earned an additional master’s degree in computer science at Columbia University in 1977. She attributes her success in her field to be her drive to produce something useful for mankind. She also credits the inspiration she has from IBM’s first female president in the company’s 100-year history, Ginni Rometty. In addition to working for IBM for the majority of her career, she was a technical member of the IBM Deep Blue Chess Team from 1996 to 1997.

Ms. Jann believes it took a lot of passion, patience, and perseverance to make it to the top of her industry. She knew that IBM was the leading company in the industry and she worked very hard to make it there. Ms. Jann also hopes to inspire other women to get involved in the computer science field. She looks at computer programming as another language and thinks more women should get involved. In 1999, she invented the Home Node Migration for Distributed Shared Memory Systems and has made many significant contributions to IBM’s Unix operation system. Furthermore, she has more than 40 patents to her name. Ms. Jann is a senior member of the Institute of Electrical and Electronics Engineers and in 2017 received the Albert Nelson Marquis Lifetime Achievement Award.
