Tim Menzies (IEEE Fellow, Ph.D., UNSW, 1995) is a full Professor in CS at North Carolina State University where he teaches software engineering, automated software engineering, and foundations of software science. He is the directory of the RAISE lab (real world AI for SE). that explores SE, data mining, AI, search-based SE, and open access science.
He is the author of over 280 referred publications and editor of three recent books summarized the state of the art in software analytics. In his career, he has been a lead researcher on projects for NSF, NIJ, DoD, NASA, USDA (funding totalling over 12 million dollars) as well as joint research work with private companies. For 2002 to 2004, he was the software engineering research chair at NASA's software Independent Verification and Validation Facility.
Prof. Menzies is the co-founder of the PROMISE conference series devoted to reproducible experiments in software engineering (http://tiny.cc/seacraft). He is an associate editor of IEEE Transactions on Software Engineering, Communications of the ACM, ACM Transactions on Software Engineering Methodologies, Empirical Software Engineering, the Automated Software Engineering Journal the Big Data Journal, Information Software Technology, IEEE Software, and the Software Quality Journal. In 2015, he served as co-chair for the ICSE'15 NIER track. He has served as co-general chair of ICSME'16 and co-PC-chair of SSBSE'17, and ASE'12.

Internationally known for revolutionary advances exploring the synergy between artificial intelligence (AI) and software engineering (SE), Dr. Menzies has authored four books and over 260 refereed publications. His publications, with over 9000 citations, have appeared in leading journals and proceedings of prestigious conferences. He has supervised seven students earning PhDs and 23 MS thesis students. Dr. Menzies' distinctive contributions have had enormous impact for SE researchers and practitioners in software quality prediction and software optimization.
Because software plays a critical role in industry, government, and society itself, improving software quality is critical. In landmark papers in 2006 and 2007, Dr. Menzies was an early pioneer in applying data mining and AI to software quality predictors, introducing a method which identified software modules likely to contain defects. This method had a 71 percent mean probability of defect detection, significantly higher than the code inspections commonly used in software practice.
In his software quality prediction research, Dr. Menzies identified a serious problem: often, the analysis in SE papers is not reproducible because data underlying the analysis is unavailable. To address this problem, Dr. Menzies developed PROMISE, a public data repository of software data, in 2005 publishing a paper introducing PROMISE and co-founding the PROMISE workshop, so successful it became a conference in 2008. Today, the PROMISE repository contains hundreds of data sets used in thousands of papers by researchers around the world.
Dr. Menzies is a pioneer in applying data miners to optimize software-intensive systems. In 2002, he discovered that analyzing such systems with data miners augmented with genetic algorithms led to faster analysis and better optimizations. Even for systems with millions of configuration options, Dr. Menzies’ optimizers quickly learn how to make code run quicker, make web servers handle more traffic, and compile programs faster. Dr. Menzies' optimizers have been applied at NASA for reasoning about safety-critical aerospace software.
Dr. Menzies has also applied his optimization techniques to understand the unstructured textual components of software artifacts and software research papers. His was one of the earliest successful efforts applying text mining and AI to the notes of software test engineers. By identifying anomalous reports that required a second opinion, he could increase assurance of NASA systems while reducing the overall effort required to achieve that assurance. Recently, he has designed tools that can review 10,000s of papers to learn the structure of the SE scientific community. These tools can guide researchers and practitioners to find relevant work that might otherwise be overlooked.
Dr. Menzies' contributions to SE and AI are widely recognized. For his research, in 2017, Dr. Menzies received the MSR (Mining Software Repositories) Foundational Contribution Award as "Recognition of fundamental contributions in the field of data mining software repositories which helped others advance the state of the art." International databases of scholarly achievement rank Dr. Menzies number three world- wide both in software analytics and in SE and data mining. Recently, Dr. Menzies clustered 35,000 papers from the last 25 years of top-SE journals and conferences. In the "software metrics" cluster, Dr. Menzies is the top-ranked author. In the papers from top-ranked venues, Dr. Menzies' h-index of 48 places him number 11 overall.
Dr. Menzies' contributions have had world-wide impact in software practice. In 2005, Turkish researchers found that when commercial teams restricted code inspections to 25 percent of the files identified by Dr. Menzies' methods, they detected 88 percent of the existing code defects. In 2005, his students commercialized his defect detection methods in the Predictive tool suite, subsequently purchased by companies such as Chevron, Northrop Grumman, LogLogic, Inc., and Compagnie Financière Alcatel, to find code defects. In 2017, the US Software Engineering Institute used Dr. Menzies' optimizers to guide discussions about costly updates to Department of Defense software.
NASA has benefited enormously from Dr. Menzies’ research. In 2005, as science chair at a NASA facility, he received a commendation award from NASA’s Chief of Mission Assurance saying: "...A great researcher in his own right, ...Tim has raised the bar on quality and level of work [expected] from our researchers." NASA used his algorithms in 2008 to find violations in Space Shuttle launch requirements; in 2010, to quickly explore the design of next-generation new Air Traffic Management concepts; and in 2017 to find better monitoring strategies for pilots flying planes in safety-critical situations. In 2016, based on Dr. Menzies' research, NASA's Jet Propulsion Laboratory created the NASA Analogy Software Cost Model as its official tool for predicting software development costs.
Tim Menzies, Jeremy Greenwald, Art Frank, “Data mining static code attributes to learn defect predictors,” IEEE Transactions on Software Engineering, Vol. 33 (1), 2-13, 2007. Dr. Menzies is a pioneer in the development of predictors of software quality learned from data miners. A notable finding of this paper is that Dr. Menzies' methods (including decision trees and Bayesian learning) have a 71 percent mean probability of defect detection--a rate significantly higher than human manual inspections. The paper, with more than 920 Google Scholar citations, is one of the 100 most cited papers in software engineering. Moreover, nine of the 50 most cited papers in the IEEE Transactions on SE (2012-2017) use methods and/or data from the databases used by this paper. Methods for software defect prediction introduced in the paper have been applied commercially around the world. In this paper, Dr. Menzies was the lead researcher —he defined the problem, the technical approach, and designed and coded all of the experiments.
Martin S. Feather and Tim Menzies, "Converging on the optimal attainment of requirements," Proceedings, IEEE Joint International Conference on Requirements Engineering, 2002. Although optimization methods for numerical systems have been used widely, applying these methods is often ineffective in complex software systems where each "if" statement divides the software into regions with different properties. For software, Dr. Menzies found that applying non-numeric optimizers, e.g., simulated annealing or genetic algorithms, is effective. This paper is the first of its kind to reason about solutions to software requirement problems on the Pareto frontier. As witnessed by many papers in the last two years, this method is now widely used by researchers in the software requirements community. For this paper, Dr. Menzies led the AI-part of the research, and designed and implemented the AI algorithm used in the analysis.

This paper, with over 185 citations, describes one of the earliest successful efforts applying text mining methods to the notes of software test engineers. The method introduced in the paper identifies anomalous reports requiring a second opinion, thus increasing software quality assurance while reducing the overall effort required to achieve that assurance. For this work, Dr. Menzies was the lead researcher, defining the overall vision of the paper, as well as building the tools and running all of the experiments.
