BACKGROUND

I received my bachelors degree in electronics from the Indian Institute of Technology, Madras in 1984. I then went to Washington University, St. Louis, Missouri where I received my Masters in electrical engineering (1987), and a doctorate in electrical engineering (1989). I have been a faculty member at Rensselaer since then.

RESEARCH INTERESTS

My lab develops multi-dimensional image analysis algorithms in service of applications in biology and medicine (talk). We collaborate with a long and growing list of colleagues in diverse disciplines. Our work is supported by federal agencies (e.g., NSF, NIH, US Army), private foundations (e.g., Cure Huntington’s Disease Initiative) and companies (e.g., Siemens, MBF Biosciences, Pfizer) for which we are thankful.

The world of biology is on the move – biological investigations are shifting (i) from qualitative and observational towards quantitative; (ii) from reductionist approaches towards the study of integrated systems consisting of multiple interacting components; (iii) from sequential experimentation towards high-throughput and high-content studies; and (iv) from static observations of fixed tissue towards dynamic observations of living tissue.

Aside from increased demand for quantification, there is a fundamental shift in the types of quantitative measurements and inferences that are sought from images. For example, integrative studies of complex systems (e.g., brain tissue) require measurements of structural and functional relationships among the components of the system, in addition to traditional morphometry of the components. The emergence of imaging-driven systems biology is another source of demand for image analysis technology. Increasingly, biochemical and biophysical models are being mapped to spatial compartments derived from actual microscopy data to achieve unprecedented realism in computational biology. Imaging is essential for studying cell behaviors that depend on morphology, connectivity, and spatial relationships with neighboring structures.

Biological Image Analysis: In the biology area, much of my current activities revolve around characterization of complex & dynamic biological systems such as neurovascular stem-cell microenvironments, the mammalian immune system, cortical tissue surrounding neuroprosthetic devices (see figure below), tumors, analyzing the dynamics of stem-cell differentiation in vitro, optimization of engineered tissue constructs, and mapping embryonic development in vivo. A major recent focus of my laboratory has been on stem cells and functional tissue engineering. This is a collaborative project with many partners. A summary of these efforts can be found in this talk.

 

We work on images that are 3-D, multi-temporal, multi/hyper-spectral (indicating multiple chemical species), and from multiple modalities. They are challenging to process, due to high variability and size. They require combinations of techniques, including statistical modeling, reconstruction (talk), enhancement, segmentation, registration, robust estimation, pattern analysis, and web/parallel programming. These tasks are computationally demanding; therefore, high-performance computing is an integral part of our work. Recently, RPI acquired a 100 teraflop supercomputer, and we have been having a lot of fun with it.

The FARSIGHT project in my laboratory is developing multi-dimensional image analysis tools that can handle the burgeoning complexity and volume of modern microscopy data; and the image-based measurement needs of modern biology. (talk)

Modern optical microscopy has emerged as a tool of choice for conducting diverse biological investigations at the sub-cellular, cellular, and tissue levels. The widespread availability of confocal and multi-photon microscopes and high-NA objectives, have made high-resolution (axial and lateral) three-dimensional (3-D) imaging of multiple structures and functional markers routine. Burgeoning libraries of organic and inorganic fluors (such as conjugated quantum dots) enable simultaneous labeling of multiple structural and functional markers. Fluorescent protein tagging enables imaging of processes in living systems. Time-lapse imaging of living tissue is enabled by controlled-environment chambers, and minimally-damaging imaging modalities.

By combining techniques, processes such as morphological and chemical dynamics, molecular transport, chemical dynamics, gene circuits, and signaling can be recorded. Furthermore, these processes can be recorded in the spatial context of intact tissue, unlike techniques like arrays and flow cytometry that disrupt spatial information. The availability of spectral- and time-resolved photon detection systems is enabling fluorescence spectral lifetime studies. The availability of “fusion microscopes” that incorporate multiple imaging modalities on the same platform allows measurement of multiple types of spatial, biochemical, and physical measurements. Finally, a set of supporting technologies ranging from image pre-processing software to high-throughput specimen preparation instruments have further magnified the capabilities of optical microscopy.

SOFTWARE TOOLS

Two examples of software tools developed in our laboratory are Quantitative 3D-catFISH (Compartmental and Temporal Analysis of Fluorescence In-Situ Hybridization Signals) and RPI-Trace3D. Quantitative cat-FISH is an innovative software program that can quantify the spatio-temporal patterns of immediate early gene transcription activity from multi-dimensional images of rat hippocampi after the animals have run through specially designed cognitive tasks such as mazes (talk). RPI-Trace3D can rapidly trace neurons, provide detailed morphometry, and analyze changes over time. It has been commercialized by MBF Bioscience. It is being used at the Wadsworth Center to quantify the patterns of growth of neurons on nano-engineered surfaces (talk). It is being used at Harvard Medical School to quantify changes in tumor microvasculature. It is being used at Wadsworth to quantify vascular changes caused by the insertion of neural implants. Our current focus is on developing a new generation of associative image analysis tools named FARSIGHT. Here is what it looks like on our screen.

Biomedical Image Analysis: The Retina project at Rensselaer is developing core image analysis technologies that can enable a new generation of ophthalmic instruments that are “spatially aware.” This new generation of instruments will have a built-in robust computer vision system that detects the key structures of the retina, tracks them over time, and maintains a dynamically updated map of the entire retina. Using such a map provides important advantages. For example, spatial referencing relative to a pre-computed map avoids the drift problem that is endemic to traditional tracking algorithms. This core computer vision-based system can be employed in diverse retinal applications as a building block (talk).

This is a multi-faceted project, and involves a large number of collaborators, and algorithms for vascular and non-vascular feature extraction, registration, real-time tracking, parallel/multi-threaded computation, change detection, change classification, and the construction of integrated hardware/software systems. A particular emphasis of this project has been the development of opportunistic and exploratory computer vision approaches that are designed for real-time use. For instance, our algorithms perform just-sufficient and highly-prioritized feature extraction to perform real-time spatial referencing. To make such systems work in real time in a predictable manner, we have had to develop elaborate methods to migrate large and sophisticated computer vision algorithms to the linux kernel space.

A recent emphasis area for the Retina project has been the analysis of changes over time (longitudinal changes) occurring in human retinas. We are interested in structural as well as functional changes. A talk summarizing this aspect is available. (talk)
