Evidence supporting scientific strength

Likai Ji’s most substantial visible contribution is a first-author study showing that porcine deltacoronavirus nucleocapsid protein interferes with porcine RIG-I dsRNA binding and K63-linked polyubiquitination, a mechanistically specific innate-immunity claim supported by molecular and cellular experiments. The paper has 74 OpenAlex citations, making it the strongest single citation signal in the supplied record. PDCoV–RIG-I mechanism

A second first-author article examined species-specific suppression of IRF7-induced type-I interferon through ubiquitin–proteasomal degradation, reinforcing a coherent research trajectory in coronavirus immune evasion. PDCoV–IRF7 mechanism

Research breadth and limitations

The supplied OpenAlex profile attributes work spanning porcine antiviral signaling, viral metagenomics, virome diversity, SARS-CoV-2 interferon biology, and a review of E3 ubiquitin ligases. This suggests broad participation in virology, but authorship position varies: Ji is first author in the two PDCoV papers and the ubiquitin-ligase review, while several metagenomics and SARS-CoV-2 papers list Ji as a middle author. Consequently, publication counts and citation totals indicate visibility and collaboration, not independently established leadership across every topic. The separate record reporting 7 papers, h-index 2, and 70 citations may represent incomplete indexing or author conflation; the supplied information does not resolve this identity issue.

The strongest concerns are evidentiary rather than misconduct-related: the available material does not provide full methods, effect sizes, confidence intervals, replication details, raw-data audits, or contribution statements for the complete portfolio. Citation counts are database-dependent, field-dependent, and time-dependent; the supplied OpenAlex counts also show 2025–2026 citations well below earlier years, plausibly reflecting citation lag rather than declining quality. The evidence supports a productive and scientifically relevant researcher, but not a world-class independent investigator based on the supplied record alone. Confidence: moderate.

 BGPT Author Review

Scientific Quality

The record indicates meaningful mechanistic virology expertise, multiple first-author contributions, coherent work on innate antiviral signaling, and substantial attributed citation impact. The score is restrained because authorship roles, identity matching, complete publication coverage, reproducibility evidence, independent leadership, and detailed study-level quality data are incomplete or inconsistent.

Communication Quality

The supplied titles and reported article themes communicate technically specific questions reasonably well, especially for mechanistic virology. Communication quality cannot be judged confidently across the full corpus because full texts, figures, writing samples, and reporting details were not supplied.

Author Novelty

The PDCoV studies appear to make mechanistic contributions concerning RIG-I, IRF7, ubiquitination, and interferon suppression, while the broader portfolio includes established metagenomic and review approaches. The evidence supports useful originality but not enough to establish field-defining novelty.

Scientific Rigor

Mechanism-oriented experimental work and repeated focus on molecular antiviral pathways support moderate-to-good rigor. A higher score is not justified because the supplied data omit study-level controls, effect sizes, replication information, preregistration, raw-data verification, and detailed contribution records; several publications are collaborative and some are reviews or observational virome surveys.
