Hi. I'm Iñigo Urteaga.

I am an Associate Research Scientist in the Applied Physics and Mathematics department at Columbia University and affiliated with its Data Science Institute. I have specialized in statistical machine learning, computational Bayesian statistics, approximate inference methods, and sequential decision processes.

My research focuses not only on the development of Bayesian probabilistic models and algorithms, but also on their application to a wide range of disciplines. I am currently working on descriptive, predictive, and prescriptive modeling with applications in science, engineering and healthcare.

I was a data-science postdoc at Columbia University from 2016 to 2018 working with Prof. Chris Wiggins and Prof. Noémie Elhadad on statistical machine learning for healthcare data, in the context of electronic health records and self-tracked data.

I completed my Ph.D. in Electrical Engineering at Stony Brook University in 2016 under the supervision of Prof. Petar M. Djurić. My dissertation is entitled "Sequential Monte Carlo methods for inference and prediction of time-series". My research attracted interest in econometrics (for prediction in stochastic volatility models) and biomedicine (for the study of fetal heart-rate signals).

I previously obtained my degree in telecommunications engineering from the UPV/EHU Faculty of Engineering in Bilbao, Spain, and worked in Research and Development projects at Tecnalia.

These are my main areas of research.

Bayesian Theory

I am interested in probabilistic modeling in general, and Bayesian statistics in particular. I study Bayesian methods and their application to a plethora of problems.

Approximate Inference

I have specialized in the study and application of Monte Carlo and Variational methods, such as Sequential Monte Carlo, MCMC, and variational techniques.

Stochastic Processes

My dissertation is on the description, estimation and prediction of stochastic processes. I have extensively worked with ARMA, FARIMA and related models for time-series data.

Non-parametric Bayesian models

I am interested in the adoption of non-parametric Bayesian models (e.g., Gaussian, Dirichlet and Pitman-Yor processes) for statistical learning.

The multi-armed bandit problem

I have been working on the Bayesian analysis of the multi-armed bandit problem, by exploring the use of approximate inference and flexible Bayesian reward modeling.

Reinforcement learning & prescriptive modeling

I am interested in the study of sequential decision processes in general, and its application to real-life applications: e.g., healthcare in particular.
