Ph.D. MathematicsStanford University, USA2011
B.S. Mathematics (Summa Cum Laude)Universidad del Valle, Cali, Colombia2006
Research Interests: Geometric and Topological methods for the analysis of data

Current projects: Periodicity in Gene expression data, Persistent homology of time-delay embeddings, Persistent cohomology and projective coordinates, Obstruction theory for data analysis, Persistence diagrams, densities and machine learning, Topological reconstruction of the otic placode, Time-delay embeddings, chaos and chatter

My research focus lies at the intersection of algebraic topology, data analysis and computational methods. My main interest consists in the application and adaptation of ideas from algebraic and geometric topology to the study of high-dimensional and complex data. Other interests include computer vision and computational biology.

Areas of Interest:

Computational Topology
Data Analysis
Computer Vision
Computational Biology
