pathsim
Interactive simulator of canonical cell-signaling models — MAPK/ERK feedback oscillations and zero-order ultrasensitivity. Tune parameters and a drug dose; the kinetics update live.
A working home for the tools, research, and projects of Robinson Vidva, a computational biologist working across neurodevelopment, immuno-oncology, and drug discovery. Most of the tools below run entirely in your browser: free, open-source, and no sign-up.
His work centers on integrating transcriptomics, metabolomics, and genomics data to understand disease mechanisms and weigh therapeutic options, with a recent focus on pediatric neurodevelopment.
Focus areas — multi-omics, neurodevelopment, immuno-oncology, drug discovery, data science, and systems biology.
Tools you can use
Free, browser-based tools for computational biology — open and use them right now, no install or sign-up.
DrugInteract
Educational drug-interaction reference that checks what each drug's FDA label says about another. Fully client-side.
enrichlite
Gene-set over-representation analysis for human and mouse that runs entirely in the browser. GO, Hallmark, Reactome.
drugtargets
Drug-target exploration and repurposing-hypothesis tool built on Open Targets and openFDA.
Selected work
Neurodevelopmental data analysis
Multi-omics analysis of preterm-birth effects on brain development, with behavioral phenotyping in mouse models using DeepLabCut and B-SOiD.
Immuno-oncology & precision medicine
Cancer-genomics analysis across 500+ cell lines and immune-pathway interactions to identify therapeutic targets and biomarkers of treatment response.
Predictive disease modeling
Pathway models for autoimmune disease and cancer therapeutics, validated against patient datasets; the underlying methods contributed to two granted drug-repurposing patents.
Open-source scientific tools
First-authored MyVivarium, an open-source cloud platform for research animal colony management, alongside the browser-based analysis tools above.
