Daniel Patterson

I’m an Assistant Teaching Professor at Khoury College of Computer Sciences at Northeastern University.

I got my PhD at the PRL Lab, studying programming languages with Amal Ahmed. My dissertation was about the semantics of language interoperability.

Before that, I helped start and run a worker-owned software contracting company, Position Development. I studied math and computer science undergrad at Brown University where I worked with Shriram Krishnamurthi, helping to design the Pyret programming language.

Contact

The easiest way to get in touch is via email: [email protected]. Note that if you have another email address for me, it will probably work as well.

Drop-in Hours

You’re welcome to come talk to me about anything (related to what I’m teaching, research I’ve done, or really, anything else), though students who are currently enrolled in classes I’m teaching will get preference.

Fall 2024, I’ll have in-person drop-in hours, Mondays 1:30-2:30pm and Wednesdays 3:00pm-4:00pm, at my office, 317 Meserve Hall.

If you are unable to make that time, or would like to meet virtually, reach out via email.
