Our research at the Krishnaswamy Lab focuses on applying machine learning methods to high-throughput high dimensional biological data. Our research projects aim to study and develop algorithmic approaches to naturally process data, visualize it, understand progressions, find phenotypic diversity, and infer patterns.  Below are our key research areas and priorities, along with some relevant projects:

 

Unsupervised Deep Learning

Manifold Learning and Data Geometry

Diffusion Maps, MAGICPHATE

Graph Signal Processing and Filtering

Information Theory and Gene Logic

Single-Cell, High-Throughput, and High-Dimensional Data

Single-cell RNA sequencing (e.g. 10x genomics) 

CyTOF

Biological Systems

Developmental (Embryoid Bodies, Brain organoids, Mouse Brain, Hematopoiesis)

Immunology (Dengue, Zika, HIV, Cancer Immunotherapy, Lupus, Type 1 Diabetes)

Cancer (EMT, Immunotherapy)
