Dr Thomas Sewell is a researcher in the field of applied software verification, using formal methods techniques to guarantee the trustworthiness of real software. He has been a key contributor to the L4.verified project and its successors, working at NICTA, UNSW and CSIRO Data61. The L4.verified project used interactive approaches to prove the functional correctness of the seL4 microkernel. In his PhD work at UNSW, he used an SMT-based method to establish the correctness of binary programs produced by compiling C code. He also found particular applications of this binary analysis in the case of low-level embedded program with essential timing constraints. More recently, Thomas has moved to Chalmers University, Sweden, to join the CakeML project, which produces a verified compiler and runtime for a language similar to Standard ML.
Wenjie Zhang is an Associate Professor in the School of Computer Science and Engineering, the University of New South Wales. She received her bachelor and master degrees from Harbin Institute of Technology in 2004 and 2006, and her Ph.D. degree from the University of New South Wales in 2010. Wenjie’s research interests include graph, spatial and uncertain data management. Her work receives 4 best paper awards from international conferences. Wenjie’s research is supported by 4 ARC discovery projects and 1 ARC DECRA project. She is also involved in an industry project with HUAWEI on cohesive subgraph analysis. Her recent research focuses on algorithms, indexes, and systems in large scale graphs and their applications especially in social network analysis. Wenjie is an Associate Editor for IEEE TKDE, an area chair for ICDE 2019 and CIKM 2015, and a PC member for more than 40 international conferences and workshops.
