About NEST
Research Projects

Nanotechnology is the rapidly advancing study of manipulating and utilizing matter at molecular scales of 1-100 nanometers and has applications in nearly every career sector, including biomedical, energy, environmental, communications, and industrial. It is innately multidisciplinary, requiring experts in mathematics, physics, chemistry, life sciences, medicine, and engineering. This multidisciplinary nature allows NEST to impact students teachers across STEM disciplines. In turn, available faculty mentors reside in different departments throughout campus, and while research topics vary, they share the common goal of advancing nanomaterials research. Selected research projects focus on the design, synthesis, theory, and/or characterization of nanomaterials for applications that span biological applications, nanoparticle theory, and renewable energy.

1. Mangilal Agarwal (Electrical and Computer Engineering)

  • Research Area and Interests: The aim of Dr. Mangilal Agarwal’s group is to develop integrated nanosystems for energy, biomedical, and other applications. Nanosystems harness the new functionalities and properties of materials and devices at dimensions in the nanometer scale length (1-100 nm). Dr. Agarwal’s work includes paper-based lithium-ion batteries and sensor arrays for the detection of disease from human breath. Paper based batteries utilize conductive papers as current collectors. These conductive papers are fabricated from wood micro-fibers coated with carbon nanotube coated through layer-by-layer nano-assembly process. Sensor array integrates cross-reactive nanosensors to analyze volatile organic compounds in breath correlated with diseases conditions.

2. Lauren Christopher (Electrical and Computer Engineering)

  • Research Area and Interests:  Dr. Lauren Christopher’s research involves the application of VLSI circuits to 3D imaging algorithms to improve throughput and real-time analysis of 3D image data.  The next frontier in image technology is the extension to 3D in displays, image processing and in image capture.  These technologies are seeing growth in medical imaging (3D CT, Ultrasound, MRI) and other applications.   Dr. Christopher’s algorithmic research in 3D statistical Image segmentation uses an iterative Bayesian analysis with the Expectation-Maximization algorithm to achieve results in highly noisy images (such as Ultrasound).  This type of algorithm poses challenges to real-time clinical needs, due to lengthy convergence speeds on traditional hardware.  New challenges in data access and dedicated processing for these types of applications dictate the need for VLSI solutions.
