Networks capture how things are connected, from social ties to biological interactions. Real networks have become so large and tangled that many analyses are slow or impossible to run.

What they work on

  1. Develop methods with theoretical guarantees for estimating low-dimensional network embeddings and quantifying their uncertainty under general network models with relaxed assumptions.
  2. Design statistically principled procedures to compare network embeddings across conditions, accounting for natural variability and detecting structural anomalies.
  3. Build a framework that jointly analyzes and integrates embeddings from multiple heterogeneous networks, using their shared structure to improve statistical efficiency.

More about the research

One common fix is embedding. This means compressing each node's position in the network into a short list of numbers that keeps the essential structure. Scientists also need to know how much to trust these compressed summaries. They often have several related networks collected under different conditions, at different times or from different data types, and need to compare or combine them.

Why it matters

This is mainly methods work. It adds rigorous statistical understanding of network embeddings and how far to trust them. The resulting toolkit could help scientists in many fields analyze large networks reliably, compare networks across conditions, and spot structural anomalies, supporting more dependable conclusions and decisions from network data.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
