  • Our R Package BoolFilter, co-authored by L.D. McClenny, M. Imani and U.M. Braga-Neto, has been published by CRAN. BoolFilter implements algorithms for Partially-Observed Boolean Dynamical Systems (POBDS), a Hidden Markov Model that extends the Boolean Network model to include noisy indirect observations, with applications in Genomic Signal Processing. BoolFilter allows the user to estimate the hidden Boolean states using the Boolean Kalman Filter and Smoother, as well as infer network topology and noise parameters, from time series transcriptomic data using exact or approximate (particle) filters, as well as simulate time series transcriptomic data for a given Boolean network model. (Jan 2017)

  • Dr. Braga-Neto has been elected to the Machine Learning for Signal Processing Technical Committee (MLSP TC) of the Institute of Electrical and Electronics Engineers (IEEE) Signal Processing Society for the 2017-2019 term. The committee is at the interface between theory and application, developing novel theoretically inspired methodologies targeting both longstanding and emergent signal processing applications. Central to MLSP is online/adaptive nonlinear signal processing and data-driven learning methodologies. The IEEE MLSP TC is expected to play a central role in the next few years in shaping the IEEE policies and approaches to Big Data. (Oct 2016)

  • Our book "Error Estimation for Pattern Recognition", co-authored with Ed Dougherty, has been published by IEEE-Wiley Press. This book is the first one dedicated exclusively to the topic of error estimation for pattern recognition. It covers both classical and recent results on the performance of error estimators for nonparametric and parametric classifiers. For a sample, including table of contents and subject index, please access the publisher's website or Google Books. The book is also available from amazon.com and barnesandnoble.com. (July 2015)

  • The 2-year project "In silico modeling of microbiota-gut epithelial cell interactions for predicting dietary supplement impact on gut health" has been selected for funding by the Interdisciplinary Seed Grants for Strategic Initiatives program of Texas A&M Engineering in partnership with The Texas A&M University Division of Research (starting in Fall 2014). The PI for this interdisciplinary project is Dr. Braga-Neto, and the Co-PIs are Dr. Xiaoning Qian from the College of Engineering, Dr. Ivan Ivanov from Texas A&M Veterinary School, and Dr. Robert S. Chapkin from Texas A&M AgriLife, in collaboration with Dr. Johanna W. Lampe from the Fred Hutchinson Cancer Research Center and Dr. Cheryl L. Walker from the Texas A&M Health Science Center.

  • The project "Identification of Drought Tolerance Genes and Networks by Expression Profiling in Banana" has been funded by the Texas A&M Center for Bioinformatics and Genomics Systems Engineering, a partnership between Texas A&M Engineering and Texas A&M AgriLife. The project is conducted in collaboration with Dr. Martin Dickman from Texas A&M AgriLife and is renewable annually for a maximum of five years.

  • Dr. Braga-Neto was elected to Texas A&M Council of Principal Inverstigators as a College of Engineering representative for the 2014-2017 term. The CPI voices the concerns of the Texas A&M PI community to the high levels of administration. If you are a PI in the CoE and have questions or concerns that you want to be brought to the CPI please contact me.

  • The project "Optimal Estimation and Network Inference for Boolean Dynamical Systems" has been funded by a 3-year NSF CIF Award (starting in July 2013).

  • Dr. Braga-Neto's IEEE membership was elevated to the degree of Senior Member (September 2011).

  • The project "Theory and Application of Small-Sample Error Estimation in Genomic Signal Processing" was funded by a 5-year NSF CAREER Award (Spring 2009-Spring 2014).
