I am pursuing research in Electrical Engineering - Biomedical Signal Processing at the University of Minnesota. My research interests are in developing signal processing applications for solving real life problems. My current areas of interest include cardiac electrophysiology and rhythm management. I am working on analysis of intracardiac electrograms from electro-anatomical mapping devices for identification of sites (outside Pulmonary Veins region) to ablate for Atrial Fibrillation.

Preethy Parthiban

B.Tech, Electronics and Communication Engineering, National Institute of Technology, India, 2017
Ph: 612-626-1198

My research interest lies in developing an in-depth understanding of the heart as an electrical organ and work towards designing optimum solutions to problems that arise as a result of misconduct of these electrical signals. Working towards this goal I am interested in looking at electrical propagation at all integrated levels ranging from cellular to entire organ system. I’m currently involved in works relating to: (1) Ablation therapy- with emphasis on locating rotor pivot point- for efficient treatment of Atrial Fibrillation. (2) Identification of therapeutic pacing protocols through numerical analysis of nonlinear cardiac cell models. (3) Ex-vivo optical mapping of hearts to analyze anti-arrhythmic drug effects.

Xiangzhen Kong

B.S., Electrical Engineering, Harbin Institute of Technology ,China, 2016
Ph: 612-626-4122

I am pursuing my PhD. degree in Electrical Engineering-Biomedical signal processing and graduated from Harbin Institute of Technology (China) with a B.S. in 2016. My research interest is mainly on rotor identification in simulation, optical mapping experiment and clinic. Currently, we aim to improve and optimize existing novel mapping approaches then transfer to clinical situations, which can help with ablation treatment. Besides, I also work on clinical data analysis such as iEGMs, filter design and Labview programming.

Jieun Lee

M.S., Information and Communications, GIST, Korea, 2008
M.S., Electrical and Computer Engineering, University of Minnesota, 2012
Ph: 612-626-4122

My research interests are theory and applications of methods for predictive learning from data. My background is in statistics, signal processing, machine learning, and optimization. My previous topics include: EEG, MRI, financial data, images, and various numerical data from statistics. For the past several years, I have been applying my background in signal detection / prediction and unbalanced data classification. I am currently working on analysis of the ECG signals to reveal distinguishing characteristics of their non-linear dynamics between healthy and diseased cardiac states.

Sanket Thakare

B.S., Electronics and Telecommunication Engineering, University of Mumbai, India, 2017

Ph: 612-624-0266

I am pursuing my MS in Biomedical Engineering (2018-2020). My research interest lies in investigating clinical data and exploring various non-linear techniques to extract the hidden physiological information from the signals. I am currently working on techniques to map the extracted features of intracardiac electrograms on the patient-specific 3D heart model.

Undergraduate students

Yugene Guo


I am interested in understanding and improving device-based therapies to correct and improve functions of the heart. I currently perform data analysis to evaluate the effect of chronic vagus nerve stimulation on heart rate, blood pressure, and cardiac structure in hypertensive rat models.,

Brett Levac


I am currently an undergraduate Electrical Engineering student with plans to graduate in May 2020. My research interests include the investigation of a more novel approach to histology image analysis. I am currently working to create an analysis technique using color deconvolution for identification of fibrosis within cardiac tissue.

Sam Newell


I am currently an undergraduate in the biomedical engineering department at the UMN planning to graduate in May 2020. My research interests lie in furthering our understanding of chemical and electrophysiological disease states of the body in order to improve medical device therapies. I am currently developing an algorithm to predict SCD in order to improve ICD placement.
