  • A Model-Based Iterative Reconstruction Approach to Tunable Diode Laser Absorption Tomograph

    Fri, Sep 22, 2017 @ 10:00 AM - 11:00 AM

    Speaker: Zeeshan Nadir, Electrical and Computer Engineering, Purdue University

    Talk Title: A Model-Based Iterative Reconstruction Approach to Tunable Diode Laser Absorption Tomography

    Abstract: Many imaging and sensing problems in the fields of medical imaging, computer vision, machine learning, communications and signal processing etc. can be posed as inverse problems. Broadly, an inverse problem consists of recovering some underlying signal of interest that leads to a directly observable measurement dataset where the measurement dataset may be corrupted by noise. In the presence of sufficient quantity of good quality measurement dataset, the inversion problem can often be solved by direct methods often involving closed form inverse formulas like filtered back projection. However, when the measurement data contains noise or is extremely sparse, then such conventional techniques do not work. Tunable Diode Laser Absorption Tomography (TDLAT) is such an ill-posed nonlinear inverse problem where 2D concentration and temperature images are required to be reconstructed from a handful of projection measurements.

    Bayesian methods are a probabilistic approach to reconstruct signals by incorporating prior information about the signals in the form of a prior probability distribution. Typical 2D prior models like Markov Random Field enforce local smoothness on the images by penalizing differences between neighboring pixels. However, the major limitation of such prior models is that they cannot express non-homogeneous and non-Gaussian characteristics of the images and therefore cannot model the long-range correlations between image pixels. In this presentation, I shall present a Gaussian Mixture Model as a prior distribution which can be trained with a few training examples. In order to show the utility of this approach, I shall apply it to Tunable Diode Laser Absorption Tomography problem. I shall formulate the reconstruction problem as a Maximum-aposteriori estimation problem. I shall present an efficient multigrid algorithm to perform the resulting optimization. The results using simulated datasets show that the proposed approach can reduce reconstruction error while also resulting in a computationally efficient algorithm.

    Biography: Zeeshan Nadir is a Ph.D. candidate in the school of Electrical and Computer Engineering, Purdue University, West Lafayette, IN. In Summer 2016, he was an intern at MathWorks, Inc., Natick, MA, where he worked on MATLAB coder package. He developed a new functionality in MATLAB Coder which has been incorporated in MATLAB R2017a release. His research interests include statistical signal processing, inverse problems, computational imaging, machine learning and computer vision.

    Talk Title: Information from cell shape controls cellular responses

    Series: Department of Biomedical Engineering Systems Cellular-Molecular Bioengineering Distinguished Speaker Series

    Biography: Dr. Iyengar is a Dorothy H. and Lewis Rosenstiel Professor in the Department of Pharmacologyand Systems Therapeutics. He is the Director and Principal Investigator of the NIGMS funded SystemsBiology Center New York. Dr. Iyengar completed his undergraduate and masters degrees at Bombay University in India. He then moved to the University of Houston and completed his Ph.D. training in Biophysical Sciences. He was a postdoctoral fellow at the Baylor College of Medicine before starting an academic career at Mt. Sinai in 1980.
    The Iyengar lab is interested in understanding cellular regulatory networks at a systems level and in using this understanding to develop therapeutic strategies and phenotypic signatures for complex diseases. Dr. Iyengar is especially interested in the role of cell shape and its relationship to extracellular spaces within tissue in information processing, and he uses a combination of experimental, theoretical and computational approaches to study these questions. Dr. Iyengar has authored more than 120 research papers, written 112 invited review articles, and edited six books. He received the NIH New Investigator Award in 1980, received the Established Investigator Award from the American Heart Association, and is a Fellow of the American Association for the Advancement of Science (AAAS).

  • AI Seminar

    Fri, Sep 22, 2017 @ 11:00 AM - 12:00 PM

    Information Sciences Institute

    Speaker: Erick Moen, USC


    Abstract: Understanding how biology responds to stimuli is one of the most challenging, yet fundamental, questions in biophysics. An in depth analysis of this relationship would allow for the development of more powerful biomedical tools and could provide a roadmap for more intelligent artificial systems. To conduct this type of research, though, we need tools to ask increasingly incisive questions of the cell membrane, the epicenter of cell function. In light of these needs, this talk will describe a nonlinear optical measurement technique developed to rapidly detect subtle changes in cell membrane structure. The method is tested in multiple cell lines and the in vitro results are validated against a complementary model of the cell membrane. The measurement technique is then used to explore transmembrane potential and investigate the mechanisms underlying neuronal stimulation and inhibition. The talk will conclude with an overview of concurrent efforts to develop a multi-faceted virtual reality VR suite for immersive scientific computing and data visualization. While this work is broadly applicable to a number of fields, the approach is used here to help better understand results from in silico studies of dynamic membrane behavior. As time allows, I will discuss how specific aspects of this research could be improved by machine learning approaches and how the projects can be extended from the single cell level to networked systems.
