CI Engineering Lunch & Learn Series


Designing, building, and maintaining advanced cyberinfrastructure to support scientific use cases can be challenging.  There are numerous items to learn about, and the learning can be never ending.  As a community, it is important for all of us to be available to answer questions, propose new ideas, and build upon our collective knowledge.  

Starting in 2017 ESnet, in collaboration with the National Science Foundation, began sponsoring semi-weekly talks on engineering and engagement topics.  These CI Engineering Lunch & Learn talks are held on Friday afternoons @ 2:00pm ET using the following Zoom number:
