My main research goal is to develop scalable and parallel algorithms
available as libraries, tools and programs
to analyze large data sets and big data in general.
I am interested in both multi-threaded processing on a multicore CPU
and multi-node processing with distributed memory and distributed storage.
Target analytics span machine learning
(e.g. clustering, classification, regression, dimensionality reduction,
variable/feature selection, time series, deep neural networks)
and graphs (paths, connectivity, clique detection, vertex neighborhood).
After visiting MIT and working with Mike Stonebraker (Turing Award winner)
I became interested in parallel systems with columnar and array storage.
During a sabbatical at ATT Labs (formerly ATT Bell Labs) I worked
with Divesh Srivastava on the R language runtime,
analytics with R on streams
and networking data.
On the "Big Data Analytics" Hadoop side
I have worked with MapReduce and Spark.
Among other science applications
I have worked on superconductivity, solar power, water pollution,
microarray data, heart disease imaging and green computing.
On the corporate side,
I have extensive experience on telecommunication, insurance and retail data.
Research: Parallel Systems, Data Science
Bio: Carlos Ordonez studied at UNAM University in Mexico, getting a B.Sc. in applied mathematics and
an M.S. in computer science. He continued PhD studies at the Georgia Institute of Technology advised by Edward Omiecinski,
focusing on accelerating machine learning algorithms with scalable processing techniques,
getting the PhD in 2000.
Carlos worked at NCR from 1998 to 2006,
collaborating in the optimization of machine learning and cube query processing algorithms
on the Teradata parallel database system.
In 2006 Carlos joined the Department of Computer Science at the University of Houston,
where he currently leads the Parallel Data Systems lab.
From 2013 to 2015 Carlos collaborated with Michael Stonebraker,
regularly visiting MIT.
From July 2014 to July 2015 Carlos worked as a visiting researcher with ATT Labs-Research
(formerly ATT Bell Labs),
where he conducted research on stream analytics,
the R language and data quality with Divesh Srivastava.
His research projects have been funded by 3 NSF grants.
