(Press-News.org) DETROIT — Amiangshu Bosu, Ph.D., assistant professor of computer science in the College of Engineering at Wayne State University, received a CAREER award from the National Science Foundation (NSF) to formulate better practices involving peer code review.
Peer code review is a mandatory software verification practice among most open source and commercial software development organizations. In this practice, one or more peers inspect and approve a code change before integrating it into a project's repository. As developers spend significant effort daily on code review tasks, improving code review effectiveness is a high priority for these organizations.
“Challenges limiting code review effectiveness include code learning difficulties with limited time and code context, misunderstandings among the participants over confusing suggestions, and interpersonal conflicts due to disrespectful feedback,” Bosu explained. “In the short term, these challenges increase required efforts, delay the outcomes, increase the likelihood of rejections and frustrate the participants. In the long term, these challenges degrade software quality, cause conflicts among the participants, demotivate an inappropriately written review's target, pose barriers to newcomers' onboarding, disproportionately impact minorities and even cause long-term developers to leave permanently. Despite several studies confirming these short and long-term consequences, practical solutions to these challenges remain nonexistent.”
The five-year, $596,760 grant from the NSF’s Division of Computing and Communication Foundations will benefit Bosu’s study, “Transforming Peer Code Review Environments for Code Learning and High-Quality Feedback.”
The overarching goal of this project is to transform code review tools and workflows to address participants' challenges in understanding the code under review and communicate that understanding with others in unambiguous and constructive languages.
“The project will work to improve code reviews using empirical methods, machine learning and natural language techniques to produce tools to be used in code reviews,” said Bosu. “The new knowledge and tools will be used as an educational platform that will support students and new programmers. The project will integrate the research into education by using the tools in classes and curriculum development, using the classroom setting to gain understanding of how to support developers in professional code-review ecosystems.”
Bosu added that with the emergence of AI-based assistants such as ChatGPT and Github Copilot, developers are increasingly using AI to generate code. However, he says AI-generated code often includes errors, is of low quality and can have security defects. For that reason, manual verification techniques such as code review are becoming even more critical among software development pipelines.
“CAREER awards from the National Science Foundation are a very prestigious award for early-career faculty,” said Ezemenari M. Obasi, Ph.D., vice president for research at Wayne State University. “Dr. Bosu is most deserving of this award for his research that aims to cultivate Wayne State’s prosperity agenda by developing best practices and fueling innovation that may impact areas from education, business, emerging technologies and beyond.”
The grant number for this National Science Foundation award is 2340389.

Cancer is the monster of our society. Last year alone, more than 600,000 people in the United States died from cancer, according to the American Cancer Society. The relentless pursuit of understanding this complex disease has shaped medical progress on developing treatment procedures that are less invasive while still highly effective.
Immunotherapy is on the rise as a possible solution. Immunotherapy involves harnessing the power of the body’s immune system to fight against cancer cells. Researchers in the College of Engineering ...
An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work published in the prestigious journal Science Advances represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.
Interference among photons, a fundamental phenomenon in quantum optics, serves as a cornerstone of optical quantum computing. It involves harnessing the properties of light, such as its wave-particle duality, ...
Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.
The study offers the first experimental evidence that chemicals present as additives in microplastics can leach into human sweat, and then be absorbed through the skin, into the bloodstream.
Many chemicals used as flame retardants and plasticisers have already been banned, due to evidence of adverse health effects including damage to the liver or nervous system, cancer, and risks to reproductive health. However, these chemicals ...
Mount Sinai scientists, in collaboration with researchers from the Carlos III Health Institute (ISCIII) in Madrid, Spain, have located and identified alterations in the monkeypox virus genome that potentially correlate with changes in the virus’s transmissibility observed in the 2022 outbreak. The findings were published April 18 in Nature Communications.
Monkeypox virus (MPXV) is a double-stranded DNA virus that can infect animals and humans. MPXV causes a disease known as mpox, with symptoms that include fever, swollen lymph nodes, and a rash. Most cases are mild and tend to get better on their own; however, mpox ...
The number of biological products registered in Brazil in recent years for crop protection against agricultural pests has surpassed that of agrochemicals. Around 90% of the area under sugarcane cultivation in the country, for example, already uses natural enemies such as microorganisms, macroorganisms, biochemicals (compounds of natural origin that control pests and diseases) and semiochemicals (molecules that induce behavioral responses in target organisms).
The data were presented by José Maurício Simões Bento, a ...
The longstanding advice to “check your baggage at the door” may not be the best way for leaders to engage and empower their employees. Instead, acknowledging that leaders are complete individuals with experiences outside of the office is a key factor in assisting them with the challenging, exhausting and often thankless work they do daily.
According to new research from the University of Florida, leaders who reflect on gratitude that they receive from family members at home feel higher levels of ...
Researchers at Baylor College of Medicine in collaboration with the University of Arizona led a study that can help surgeons obtain biofeedback of their posture during long surgical procedures. Ultimately, the aim is to reduce the stress associated with maintaining static postures while operating.
Published in the Journal of Neurosurgery: Spine, this pilot study evaluated the feasibility of using wearable technology to assess the posture of neurosurgeons during long spine and cranial procedures. The findings show that wearable technology is a feasible and reproducible approach to provide ...

New York Valves 2024, the expanded iteration of CRF’s renowned annual Transcatheter Valve Therapy (TVT®) conference, will take place June 5-7 ...
About The Study: This study including 903 women with BRCA germline pathogenic variants found that a breast cancer diagnosis less than 10 years postpartum was associated with higher risk of mortality compared with nulliparous women and women diagnosed at least 10 years postpartum. These results should inform genetic counseling, prevention, and treatment strategies for BRCA pathogenic variant carriers.
