Computational research on scientific image integrity, responsible AI, reporting quality, and the availability of research resources.
How can we make the scientific record easier to trust?
Research integrity depends on evidence that people can inspect. We develop computational methods to identify patterns that deserve attention, measure uncertainty, and help researchers evaluate scientific work.
Scientific images and figures
Our work examines image reuse, image manipulation, and graphical inconsistencies. A detection method helps locate and characterize a problem; interpretation still depends on the original material and the scientific context.
Responsible use of AI
Language models can assist scientific work, but their behavior needs evaluation. We study how models respond to research-integrity scenarios, including requests that disguise misconduct as ordinary scientific tasks.
A durable, inspectable record
Links to code and data are part of the evidence behind a paper. Our resource-longevity work examines why these links persist or disappear, while journal-screening research investigates the signals and limits of automated assessment.
An open question
How can screening systems communicate uncertainty clearly enough to help investigators without turning a model's score into a verdict?

SciIntBench evaluates how language models respond to scientific requests framed as explicit misconduct, covert misconduct, or legitimate work. It measures both refusal of problematic requests and helpfulness on benign ones.
This study evaluates whether journal websites and publication metadata can support large-scale screening for questionable open-access journals. It treats automated predictions as a way to focus expert investigation.

This study examines violations of the proportional ink principle: the amount of visual ink representing a value should agree with that value. It develops an automated method for detecting these inconsistencies in scientific bar charts.

Code and data links can stop working long after a paper is published. This study examines which features of a resource, its host, and its associated publication help explain and predict its availability over time.
Image similarities need a reference point: a repeated pattern might be rare, or it might be common in scientific imagery. This preprint develops a statistical baseline for estimating how often a feature could occur by chance.
Scientific images have different properties from everyday photographs. This preprint develops a detector tailored to scientific imagery and tests whether inconsistencies in image noise can reveal manipulated regions.
