Surgeon and biomedical researcher interested in how gastrointestinal microbes injure the mucosa and drive carcinogenesis. My bench work has centred on Helicobacter pylori gastritis and on Porphyromonas endodontalis in gastric cancer, and I have completed a three-year surgical residency. I am looking for a PhD position in translational gastrointestinal or oncology research in Europe.

I also prepare figures and graphical abstracts for other researchers.

Research

My master's project asked why Helicobacter pylori infection keeps the gastric mucosa inflamed, and whether restoring the Nrf2 antioxidant response could interrupt that. I designed the study, established and characterised the infected chronic gastritis mouse model, ran the intervention experiments in GES-1 gastric epithelial cells — including pharmacological Nrf2 inhibition to test whether the effect depended on the pathway — did the statistics and figures, and wrote the paper as sole first author.

In the same group I was a key participant in an NSFC-funded project on how Porphyromonas endodontalis and H. pylori CagA damage the gastric mucosal barrier in gastric carcinogenesis, responsible for animal model construction and endpoint assays, and I contributed to several NSFC grant applications. I kept doing bench research during residency: on ferroptosis in colorectal cancer, and on primary cells from surgical specimens in a project on hyperparathyroidism.

What I want to work on next

How gastric and intestinal microbes damage the mucosal barrier and contribute to cancer; how the host epithelium defends itself, through pathways such as Nrf2; and questions that connect these mechanisms back to surgical oncology.

Methods I use

Mouse models of chronic gastritis and intestinal injury, from induction and grouping through intervention, tissue harvest and endpoint assays. Cell culture with drug or cytokine treatment. Western blot, RT-qPCR, immunohistochemistry, immunofluorescence and flow cytometry. Statistics and figures in GraphPad Prism; figure assembly in Adobe Illustrator.

Figure preparation

I offer figure preparation for researchers: statistical panels in GraphPad Prism, multi-panel figures assembled in Illustrator to a journal's specifications, and graphical abstracts drawn from vector elements rather than stock artwork. To discuss a manuscript, message me on Upwork or email me with the target journal and what you have so far.

Selected work

Multi-panel figure. A: western blot of CHD8 and actin in wild-type and Chd8 heterozygous embryonic mouse cortex, with CHD8 much weaker in heterozygotes. B: bar chart of CHD8 normalised to actin, about 0.9 in wild type and 0.4 in heterozygotes, P = 0.002. C to E: paired coronal micrographs of wild-type and heterozygous embryonic cortex showing CHD8 with Hoechst merged, CHD8 alone, and Hoechst alone.
Demonstration piece: a figure redrawn from a public dataset. Data: Yim K, Baumgartner M, Krenzer M, et al. Dryad dataset, doi:10.5061/dryad.3bk3j9kxv (CC0 1.0), accompanying the Cell Genomics (2025) study of Chd8 haploinsufficiency in mouse cortical development. Micrograph and blot pixels are unaltered; layout, labelling and the quantification plot were redrawn. (A) Western blot of CHD8 in male WT and Chd8+/− embryonic day (E) 16.0 cortex; actin, loading control. Arrow, full-length CHD8. (B) CHD8 normalised to actin (n = 6 per genotype); bars, mean ± SD; dots, individual animals; two-tailed Welch's t-test. (C–E) CHD8 (red) and Hoechst (blue) staining in coronal sections of embryonic cortex, acquired and displayed with identical settings. Scale bar, 100 µm.
