Ligia Nistor


I have graduated! I was a Ph.D. student in the Computer Science Department at Carnegie Mellon University from August 2009 to December 2017. I am now working for Oracle Corporation in Cambridge, MA.
I am interested in formal methods, verification, programming languages, logic, software engineering.
My email address is ligia.nicoleta at gmail.com . My CV is here.

Theses

Ph.D. Thesis: [PDF]
The code for my Oprop tool is available on GitHub. Check it out or contribute!
Thesis proposal: [PDF]
My Ph.D. advisor was Prof. Jonathan Aldrich.
I obtained my MSc in Computer Science from Oxford University in 2009.
My final thesis was titled Model-Checking Higher-Order Recursion Schemes , under the supervision of Prof. Luke Ong. You can read my thesis here.

Service

  • I served as an external reviewer for the Asia-Pacific Software Engineering Conference (APSEC) 2016.

    • Misc

    During summer 2012 I interned with Duolingo.

    I was part of the team (Team UBA) that won second place at the Social Innovation Solutions Challenge 2012 , on Jan 31 2012. Our team designed an innovative health care product for inner-city Americans.

    Personal

    I love running and reading. I like to paint and I advertise my paintings on my ArtPal page.
