Xiaokang Qiu

Assistant Professor

I am an assistant professor with the School of Electrical and Computer Engineering at Purdue University. I used to be a postdoc at MIT CSAIL, sponsored by ExCAPE and working with Jeff Foster and Armando Solar-Lezama. I received my Ph.D. in Computer Science in 2013 from the University of Illinois at Urbana-Champaign, where I was advised by Madhusudan Parthasarathy. Before starting my studies at the University of Illinois I completed my Master studies at Nanjing University, China in the group of Xuandong Li.

My research spans a range of areas in Programming Languages and Software Engineering, with focus on theories, algorithms and tools of Programming Systems, including program logics, decision procedures, automated deduction, program verification, and program synthesis.

I look for smart, motivated, hard-working Ph.D. students and undergraduate interns. Please apply to Purdue's strong Computer Engineering Programs. If you are interested in working with me, I will be more than happy to talk with you!

Software Projects

STRAND Logic Solver
STRAND ("STRucture ANd Data") is a logic that allows reasoning with heap-manipulating programs using deductive verification and SMT solvers. More details can be found at
VCDryad Program Verifier
VCDryad extends the VCC framework to provide an automated deductive framework against separation logic specifications for C programs based on natural proofs. The tool is available at:
ImpSynt Program Synthesizer
ImpSynt is a syntax-guided program synthesizer that can automatically synthesizes data-structure manipulations and their correctness proofs in tandem, from bare-bones control flow skeletons. Some examples can be found here.
PASKET Model Synthesizer
PASKET ("PAttern SKETcher") is a tool for automatically generating Java framework models for symbolic execution. The tool is available at:
JSketch Java Program Synthesizer
JSketch is a sketch-based Java program synthesizer built on top of Sketch. The tool was presented at ESEC/FSE 2015 and available at:
DryadSynth SyGuS Solver
DryadSynth is a Syntax-Guided Synthesis (SyGuS) solver that combines enumerative synthesis and deductive synthesis algorithms. DryadSynth won the CLIA track of SyGuS-COMP in 2018 and 2019. The solver was presented at PLDI 2020 and available at:
