An object-oriented idea leads to a functional language design for engineering extensible proofs.

Ende Jin, Nada Amin, and Yizhou Zhang

Symbolic methods (a type system and an analysis) aid in neural-network-based inference.

Jianlin Li, Leni Ven, Pengyuan Shi, and Yizhou Zhang

Reasoning principles for probabilistic programs that express rational agents

Yizhou Zhang and Nada Amin

Handlers for “effectful effects”? Yes, with a type system to defend abstractions.

Yizhou Zhang, Guido Salvaneschi, and Andrew C. Myers

Robots plan paths against both noise and adversarial uncertainty.

Jacopo Banfi, Yizhou Zhang, G. Edward Suh, Andrew C. Myers, and Mark Campbell

Algebraic effects (and hence exceptions, asynchrony, ...) made modular

Yizhou Zhang and Andrew C. Myers

A lot of polymorphism and extensibility in a lightweight package

Yizhou Zhang and Andrew C. Myers

The flexibility of unchecked exceptions, the static guarantees of checked exceptions, and good performance too

Yizhou Zhang, Guido Salvaneschi, Quinn Beightol, Barbara Liskov, and Andrew C. Myers

An expressive, lightweight genericity mechanism with better code reuse and stronger static checking

Yizhou Zhang, Matthew C. Loring, Guido Salvaneschi, Barbara Liskov, and Andrew C. Myers
