Biomedical Signal Analysis

The IEEE Kingston Section is proud to present the following distinguished speaker seminar:

Biomedical Signal Analysis


Date:  Wednesday, March 5th, 2014.

Time:  2:00 – 3:15 PM

Location: Queens University, Walter Light Hall, Room 205

Speaker:  Professor Sri Krishnan, Ryerson University

Abstract:  A signal can be considered to be stationary if its statistical characteristics do not change with time. However, most real world signals are non-stationary and have highly complex time-varying characteristics. Common signal analysis and modelling techniques and classical time-frequency distributions (TFDs) do not readily provide the time-varying signal features of interest. There are several limitations with the classical parametric signal representations, and these problems could be obviated by using true nonstationary signal analysis tools such as adaptive signal representations and adaptive TFDs. Construction of proper adaptive TFDs and the methodologies for extracting instantaneous and quantifiable signal parameters will be discussed in detail. The extraction and monitoring of spectral and related parameters with time is of immense use in a variety of signal analysis applications such as RADAR, biomedical, and geophysics. The application of the extraction and classification of complex instantaneous signal parameters with respect to three real world biomedical signals (cardiac electrograms, pathological speech signals and knee vibration signals) will be discussed in detail.

Speaker Bio:  Sri Krishnan joined Ryerson in 1999 as an assistant professor in Electrical and Computer Engineering, and has held the positions of assistant chair, graduate program director and chair. He was appointed associate dean (research, development and graduate programs) in 2011, and became interim dean in 2013. Dr. Krishnan was instrumental in founding Ryerson’s undergraduate degree program in biomedical engineering, the first of its kind in Canada. He oversaw the launch of several new program options in electrical engineering, and fostered numerous international collaborations and industry partnerships. Under his direction, the PhD program in electrical and computer engineering was launched, and he played a pivotal role in establishing the faculty’s Research and Innovation Office (RiO).

Dr. Krishnan’s research expertise is in biomedical signal processing. He holds one US patent and has published nearly 220 papers in refereed journals and conferences. An active collaborator with clinicians, industries and researchers, Dr. Krishnan has attracted significant research funding from many of Canada’s most prominent agencies, and holds a Canada Research Chair in Biomedical Signal Analysis. He holds a BEng in Electronics and Communication Engineering from Anna University in Chennai, India, and an MSc and PhD in Electrical and Computer Engineering from the University of

Dr. Krishnan is a registered Professional Engineer in Ontario, and a senior member of the Institute of Electrical and Electronics Engineers (IEEE). Dr. Krishnan has been the recipient of several prestigious awards including the Ryerson-Sarwan Sahota Distinguished Scholar Award in 2011, the Ontario Research Innovation Award from Biodiscovery Toronto in 2008, and the Canadian Engineers’ Young Engineer Achievement Award from Engineers’ Canada in 2007.
