We are working on CMOS based Silicon photomultiplers (SiPM) for detecting neutrons. The SiPM detectors are coupled with scintillators which output photons when impacted by neutrons. Our SiPMs can be tuned for noise and dynamic range.
Our group is interested in mixed signal circuit design techniques for various applications. Our group has recently worked on single photon avalanche diodes in standard CMOS, low noise amplifiers and potentiostat circuits for electrochemical sensing, current mode analog to digital converters, temperature sensors, pH sensors, and impedance sensors.
Our group has active research in biosensors for portable and lab on chip applications. We are interested in the design and characterization of sensors for various applications including healthcare and environmental monitoring. These sensors include CMOS based sensing and novel devices such as vertically aligned carbon nanofibers and carbon nanospikes. Additionally, we have developed sensors such as heart rate and EEG monitors.
We are interested in exploring the tradeoffs in noise and available power resources for circuit design. To accomplish this we are exploring noise models in modern processes and communication channel models of circuit systems.
Our group has been working with researchers at ORNL to develop tools to aid in detecting malicious hardware in chips and incorporating security into biosensors.
Our group has been working on vertically aligned carbon nanofiber and carbon nanospike based biosensors. We have successfully demonstrated these sensors for electrochemical sensing and cell based impedance sensing.
Nicole McFarlane received her Ph.D. from the University of Maryland, College Park in 2010 and received her bachelor's and master's degree from Howard University in 2001 and 2003 respectively. She is currently an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee, Knoxville. While at the University of Tennessee she has done significant outreach and mentoring to underrepresented groups at the, high school, undergraduate, and graduate levels. She currently serves on the Biomedical and Life Science Circuits and Systems and the Sensory Systems Technical Committees and served on the Organizing Committee for ISCAS 2017. She became a senior member of the IEEE in Sep 2017. Her research interests include developing smaller, cheaper and more effective sensing systems and devices, and mathematical modelling of these systems.
