Discover new targets for
vision restoration.

I use computational biology to discover therapeutic targets for vision restoration, combining retinal and optic-nerve atlas assembly, machine-learning-enabled integration, quantitative cell-state modeling, multi-omics, and scientific software development.

Eye1k

A pan-conditional mouse atlas of the retina and optic nerve

A unified reference to resolve retinal and optic-nerve cell types and states across development, homeostasis, injury, and neurodegeneration.

Eye1k currently integrates 13 single-cell atlases and is being developed with a consortium-based annotation strategy. The long-term goal is to use cross-condition maps to identify molecular programs and candidate therapeutic targets relevant to vision restoration.

01

Download, process, integrate & harmonize

In-house pipelines standardize public and collaborative datasets, scale analysis to millions of cells, use GPU acceleration, and apply machine-learning integration where it adds value.

02

Assemble the atlas ecosystem

Individual studies become one connected reference rather than isolated datasets — spanning retina and optic nerve, ages, perturbations, disease models, and experimental conditions.

03

Complete systematic annotation

I established and coordinate a consortium of wet-lab and domain experts who work with my bioinformatics team to resolve cell classes and subtypes consistently across the collection.

04

Ask downstream biological questions

The unified atlas enables analyses of aging, optic-nerve-crush responses, neurodegeneration, model-to-model differences, cross-species conservation, and recurrent molecular programs relevant to vision restoration.

scCS

single-cell Commitment Scores

A computational framework for quantitative assessment of cell-fate commitment from single-cell transcriptomic data, designed to describe commitment as a continuous property rather than only a discrete cell label.

Human Retinal Organoid Cell Atlas

Ongoing development of a high-resolution single-cell reference for human retinal organoids, with cross-system comparison to in vivo human retinal development and a focus on transcriptional states that emerge or diverge in vitro.

The parasite story

Polymorphic parasitic larvae that cooperate as a swimming colony

A collaboration outside my main retinal work: two morphologically and functionally distinct cercarial forms cooperate to build a swimming aggregate proposed to aid host infection — a striking example of division of labor in a parasite.
