I make pathology slides talk, and big models run on small computers.

About

I am a computational pathology researcher. My work asks a simple question: how much can a haematoxylin-and-eosin slide tell us about what will happen to a patient? I train and validate deep-learning models — pathology foundation models, multiple-instance learning, multi-centre survival analysis — that turn whole-slide images into risk scores for cancer recurrence and treatment response, and I build the open-source infrastructure that lets collaborating hospitals run those models on their own data.

Before Boston I did a PhD in the group of István Csabai at Eötvös Loránd University in Budapest, working on deep learning, complex systems and bioinformatics — from domain shift in medical imaging to AlphaFold2 mutational scans of the SARS-CoV-2 spike. Before that I read Chemistry at Lincoln College, University of Oxford; my Part II research year (2017–18) was in Justin Benesch's group, studying small heat-shock protein chaperones with gas-phase HDX and ion-mobility mass spectrometry.

Outside the lab I am CTO of Tropiflo, and I spend my evenings on systems problems: streaming mixture-of-experts models from disk so that trillion-parameter networks run on a single machine, pooling idle office Macs into one inference cluster, and making coding agents controllable by voice.

Research

Multimodal biomarkers for early-stage lung adenocarcinoma

PATH-ORACLE combines whole-slide-image embeddings with a 46-gene RNA signature to predict recurrence in stage I lung adenocarcinoma, validated across international cohorts. Weights, cut-offs and inference code are public in PATH-ORACLE-INFERENCE. The PRELUDE consortium pairs histology with omics to predict relapse in stage IA/IB disease.

Platinum response in high-grade serous ovarian cancer

Our npj Precision Oncology paper showed that histopathology and proteomics are synergistic for predicting platinum response in HGSOC. The KAIROS consortium extends this across centres.

Robustness, domain shift and interpretability

Physical imaging parameters — not just biology — drive domain shift in medical images (Scientific Reports, 2022). Spatial statistics borrowed from cosmology give interpretable prognostic features in histopathology (ICCV Workshops, 2025). And transfer learning may explain why pigeons can be trained to detect cancer on slides (Bioinspiration & Biomimetics, 2024).
