Chung-Kang Peng, Ph.D., is the Co-Director of the Rey Institute
for Nonlinear Dynamics in Medicine at the Beth Israel
Deaconess Medical Center and Associate Professor of Medicine at
the Harvard
Medical School. He is one of the founding members of the National
Research Resource
for Complex Physiologic Signals (PhysioNet) funded by the National Institute of
Biomedical Imaging and Bioengineering and National Institute of
General Medical Sciences of the National Institutes of Health.
Dr. Peng has many close international collaborations, especially, with the scientific communities in the greater China area. He is the Co-Director of the International Research-Intensive Center of Excellence in Taiwan: Center for Dynamical Biomarkers and Translational Medicine (established by the National Science Council of Taiwan in 2011). Currently, he is K.-T. Li Visiting Chair Professor of National Central University (Taiwan), adjunct Distinguished Professor of Yuan Ze University (Taiwan), and Visiting Professor of Peking University (China).
Dr. Peng has expertise in statistical physics and its application to the study of physiological measures. He has been working at the interface of statistical physics and biology since he was a graduate student. Over the years, he and his collaborators have developed several useful computational techniques, including the following:
- The detrended fluctuation analysis (DFA) (see introduction by Wikipedia), that originated from statistical physics to measure fractal properties in physiologic signals.
- The multiscale entropy (MSE) analysis approach to measure the complexity of complex signals (Phys. Rev. Lett. 89:068102, 2002; Adv. Adaptive Data Analy. 1:61, 2009).
- A new algorithm, based on information theory and statistical physics, for linguistic analysis of symbolic sequences. It has been applied to bio-medical signals (Phys. Rev. Lett. 90:108103, 2003), human languages, and DNA sequences.
- A measurement of time reversal asymmetry in heart rate time series (Phys. Rev. Lett. 95:198102, 2005).
- An ECG-based cardiopulmonary coupling analysis for the study of sleep (Sleep 28:1151-1161, 2005).
- An index for dynamic cerebral autoregulation (Biomed Eng Online 3:39, 2004; online analysis service avaiable).
These new approaches have been highlighted in Nature News and Views (Nature 419: 263, 2002), the American Institute of Physics News Update (Aug. 1, 2002), the Boston Globe (Aug. 5, 2003), the Harvard Focus (Mar. 8, 2002; Sep. 16, 2005; Dec. 2, 2005), and the Voice of Amreica News (in Chinese). These new approaches have a wide range of applications in multiple disciplines, such as mathematics, physics, economics, biology and clinical medicine. Dr. Peng's publications have been cited more than 10,800 times (h-index: 50).
