RESEARCH PROJECTS

ALGEBRAIC TOPOLOGY
(PhD thesis)

 An interplay of Topology, Algebra and Combinatorics comes together in a cyclic theory for a categorical model for the free loopspace with its circle action. In particular, we produce a small model for computing the equivariant homology of the free loopspace.

DATA SCIENCE FOR CLINICAL DIAGNOSTICS

We are working on a multi-analyte machine-learning-based classifier for Alzheimer's Disease(AD) that uses cell-free mRNA data to tell subjects whether or not they have AD. We explore the measurement uncertainty and accuracy of the classifier — it's very important to hold these type of classifiers to high standards, people's health and treatments may depend on it!
This work was done at The Data Mine - Purdue University , in collaboration with our corporate partner Molecular Stethoscope

MATHEMATICAL BIOLOGY

We implement methods from Topological Data Analysis to study cell-based pattern formation. We apply our methods to zebrafish, which get their name from their characteristic striped pattern, and study their variation in time, as well as their large-scale statistical variability.

Collaborators: Dr. Alexandria Volkening.
