Project: Microscale Cyclical Electrical Field Flow Fractionation I am studying differential electrokinetic mobility based separations of nanoparticles & biomolecules using a new technique in Field Flow Fractination (FFF) called Cyclical Electrical FFF (CyElFFF). Unlike in Normal ElFFF, in CyElFFF Gouy-Chapmann double layer is disturbed using cyclical electrical field which results in improved electrical field (from 3% to 25% and more). This advantage is utilized in separating nanoparticles/biomolecules based on their electrophoretic mobilities. My research focusses on understanding and applying this method in miniaturization of CyElFFF. So far, apart from modeling, I am successful in improving fabrication and design of micro-CyElFFF […]

I earned my BS in Electronics Engineering Technology from BYU in 2002. I am currently pursuing my MS in Bioengineering. I am working on a project where we will be creating a micro-scale DNA extraction/amplification device. The goal is to perform PCR directly on a nanoporous filtering membrane in order to reduce the number of steps involved in DNA amplification and detection and thus reduce the time and cost involved. My main area of focus in this project is providing a heating method to perform rapid thermal cycling in the PCR process. Email: R.Eich@utah.edu Website: www.eng.utah.edu/~eich

Jungkyu Kim

JungKyu Kim

Jungkyu Kim has a biomedical engineering background and is now pursuing Ph.D. in mechanical engineering at University of Utah . He is currently working on a project that involves the implementation of a microscale system for DNA extraction and amplification. This project use a nanoporous membrane that will be implemented in a microscale system, extract the DNA using the membrane, amplify the DNA using PCR or a similar technique, and monitor the reaction in real time using optics. All of these functions will be completed in one chamber and will be accomplished rapidly. Email : jungkyu.kim@utah.edu Web : http://www.mech.utah.edu/~jungkyuk

Sriram Natarajan

Sriram Natarajan has a BS degree in Chemical Engineering from the Indian Institute of Technology (I.I.T.), a MS degree from the University of Colorado and many years of industrial experience in MEMS. He is now pursuing a Ph.D. in Chemical Engineering. He is currently working on studying the flow patterns and optimizing a microfluidic device to deposit uniform spots of biomaterials on a substrate. This device, called a spotter array, has many advantages over current ink-jet methods that are used to produce spots for bioassays, proteomics etc. One of the goals of this research is to develop a commercially viable […]

I recently graduated from the University of Utah in Mechanical Engineering and currently I am pursuing my Ph.D. in Bioengineering.  My Current project is to develop hardware to amplify and monitor 1 – 10 nl reactions on a micro-fabricated chip that can be used for highly parallel real-time PCR and high-resolution melting analysis.  The eventual goal is to be able to perform whole genome sequencing.  More information about me and my research can be found at www.eng.utah.edu/~sundberg.

We are building an apparatus capable of performing a single genetic analysis in less time than a short doctor’s visit would take. Our current focus is on the DNA amplification and analysis that will be performed within the desktop instrument. We are doing the PCR in a unique way, a process that we call “Thermal Gradient PCR”. Instead of cyclically heating and cooling a vial or capillary, we just use a syringe to push the biological mixture through a small channel built into a microscope slide. By the time the fluid exits the glass channel, the number of identical DNA […]

PhD Candidate Electrical and Computer Engineering I began my work in micro fabrication in 1994 at the University of Utah as an undergraduate student.  We developed a thin-film integrated inductor/transformer process to be used in cell phone antenna impedance matching circuits.  Upon graduation I started working on magnetic memory contract for MicroMEM Inc. until December 2001. In February 2002 I returned to the University of Utah to pursue a PhD in Electrical Engineering working on a micro scale Nuclear Magnetic Resonance Spectrometer.  Our system is intended for field use and is therefore portable and very low power.  We have developed […]
