Principal Investigator

Dr. Alejandro Heredia-Langner is a Research Scientist in the Applied Statistics and Computational Modeling Group at Pacific Northwest National Laboratory (PNNL).  While at PNNL, Dr. Heredia-Langner has worked on building, applying and analyzing results from statistically designed experiments in areas of sensor modeling and optimization for the detection of explosives, studying the effects of particle size on the transport of chemical waste, and simultaneous optimization of multiple responses in chemical and biological systems. In optimization, he has created genetic algorithms for improving the design of a gamma-ray spectrometer, searching for reliable features in complex problem spaces when the underlying phenomenon is poorly understood, maximizing signal detection using data from a portal detector, the creation of an algorithm for peptide sequencing, and the implementation of a feature-selection algorithm for subject re-identification.  He has an undergraduate degree in Chemical Engineering and a Ph.D. in Industrial Engineering.
