Applications requests left unanswered

I do not answer emailed application requests to

monitor a research project for high-schoolers (since the necessary mathematical background in set theory, order theory, and logic is not taught in high school);
undergraduate applications (since I am not in charge of undergrad admissions), see www.nyu.edu/admissions/undergraduate-admissions.html and cs.nyu.edu/home/undergrad/admissions.html
masters applications (since I am not in charge of grad admissions, either), apply instead to cs.nyu.edu/home/master/prospective_admission.html
PhD applications not in abstract interpretation and its applications to semantics, verification and static analysis (since I only work on abstract interpretation and its applications), in all cases apply to cs.nyu.edu/home/phd/admission.html
RA, TA, GA from students that have not followed all of my classes with success (since assistants should be competent and knowledgeable);
sign recommendation letters for unknowns, including any king of petition and even when the letter is provided (since my recommendation letters reflect only my own opinions)!

_{(Radhia Cousot Award)}

I work on formal methods (i.e. how to use mathematics to design programs) as opposed to software engineering (i.e. how to design programs avoiding any use of mathematics). Abstract interpretation is a mathematical theory to design program semantics (formalizing what programs do when executed), program properties (formalizing what are the interesting properties of program executions), deductive program verification (how to formally prove that program executions do have formal properties, including model checking), and program analysis (how to mechanically infer formal properties of program executions, including typing).

The book ``Principles of Abstract Interpretation'' is available at MIT Press since September 21st, 2021 (ISBN-13: 978-0262044905, ISBN-10: 0262044900). The book webpage is https://github.com/PrAbsInt.
