Robert Lee Grossman is an American computer scientist and bioinformatician at the University of Chicago.
In 1989, working with Richard Larson, he showed that trees have a natural multiplicative structure and are in fact a Hopf algebra.
With Stuart Bailey and Yunhong Gu, he developed open source software to move large datasets over wide area high performance networks (PTool and the UDP-based Data Transfer Protocol or UDT).
[5] During this period, he also founded the Data Mining Group, which develops data mining standards, and led the technical working group that developed the Predictive Model Markup Language (PMML), which is now the dominant standard in analytics.
Since 2010, he has primarily focused on data science and its applications to biology medicine, health care and the environment.
