The Association for Computing Machinery, the world's largest and most prestigious society of computing professionals, has named Tanzeem Choudhury, Robert D. Kleinberg and Steve Marschner 2021 ACM Fellows. The trio join 29 previous Cornell Ann S. Bowers College of Computing and Information Science ACM Fellows.

The ACM Fellows program recognizes the top 1 percent of members for their outstanding accomplishments in computing and information technology and/or outstanding service to ACM and the larger computing community.

• Choudhury, the Roger and Joelle Burnell Professor in Integrated Health and Technology at the Jacobs Technion-Cornell Institute at Cornell Tech in Information Sciences, was recognized for her contributions to mobile systems for behavioral sensing and health interventions.
• Kleinberg, a professor of computer science at Cornell Bowers CIS, was honored for his contributions to online learning and decision problems.
• Marschner, a professor of computer science at Cornell Bowers CIS, was recognized for his contributions to modeling the appearance of physical materials.

This year, ACM named 71 members Fellows for wide-ranging and fundamental contributions in areas including algorithms, computer science education, cryptography, data security and privacy, medical informatics, and mobile and networked systems ─ among many other areas. Fellows are nominated by their peers, with nominations reviewed by a distinguished selection committee.

“Computing professionals have brought about leapfrog advances in how we live, work, and play,” said ACM President Gabriele Kotsis in a press release. “The ACM Fellows program honors the creativity and hard work of ACM members whose specific accomplishments make broader advances possible.”

The Fellows induction ceremony will take place at the ACM Awards Banquet in June 2022. Additional information about the 2021 ACM Fellows, as well as previously named ACM Fellows, is available through the ACM Fellows website.
