In “How engineers can help doctors save lives,” Dr. Nataraj described the human body as a complex dynamic system that cannot be fully understood by conventional medical diagnostics. Given the diversity of the human race, it is difficult to define “normal,” and as a result millions of patients are incorrectly diagnosed each year, leading to unnecessary treatments and death.
Dr. Nataraj believes engineers can offer a solution. “Physics, mathematics and computer algorithms can be used effectively and intelligently to make this situation a whole lot better.”
During his talk, Dr. Nataraj discussed these ideas and shared results from research he is conducting with the Children’s Hospital of Philadelphia (CHOP).
In collaboration with CHOP doctors, he is applying a machinery diagnostic approach to studying data on periventricular leukomalaci, a mysterious neurological damage that occurs in neonates.
An article in the year book of International Medical Informatics Association has studied 1254 papers on the medical decision making systems and mentioned only 25 papers. In the category of decision support systems for a complex clinical conditions only 5 papers were mentioned, including a paper co-authored by Dr. Jalali and Dr. Nataraj with collaboration from Children’s Hospital of Philadelphia (CHOP).
The paper was entitled "Prediction of periventricular leukomalacia occurrence in neonates after heart surgery" and published in the IEEE ournal of Biomedical and Health Informatics.

Conventional medical diagnostics isn’t working and needs help. The reasons are: the human body is a very complex dynamic system, there is a lot of diversity among humans, and it is difficult to define ‘normal’.
But, this where we engineers can come to the rescue! Physics, mathematics and computer algorithms can be used effectively and intelligently to make this situation a whole lot better, and prevent millions of missed diagnoses, unnecessary treatments and deaths.
This talk will discuss these ideas and share results from our research in which we are collaborating with doctors to study a mysterious neurological damage that happens in neonates.

The Dean of the College of Engineering, Dr. Gary Gabriele, officially launched the activities of the new Research Center for Data Analytics of Dynamic Systems. In a communication to the University community, Dr. Gary Gabriele said “The center can be expected to make many fundamental advances; in addition, the application areas for this area of research are diverse and vast and offer an exciting vista of opportunities.” Please read hereafter two paragraphs extracted from the Dean’s communication.
“The focus of this new interdisciplinary research center will be the development of new tools and techniques for analytics of dynamic systems with applications in engineering, medicine and finance. Capitalizing on the fact that there is a profusion of big data and that we are in an increasingly connected world employing sensors everywhere, the new center will focus on how best to make use of this data to divine the underlying dynamics for analysis, diagnostics and prognostics. The uniqueness of the center is a set of tools (which have been developed over the last decade at Villanova) that seek to forge an optimal synthesis of nonlinear science and machine learning. It is expected that there would be significant synergy with the existing engineering research centers at Villanova, as well as other university centers such as Center for Business Analytics, and Center for Statistics Education. The center can be expected to make many fundamental advances; in addition, the application areas for this area of research are diverse and vast and offer an exciting vista of opportunities."

Abstract: In this lecture I will paint a broad picture of the nonlinear world and examine implications of this view on science and engineering. Through carefully chosen examples from everyday life, science and engineering I will show just how nonlinear and dynamic our world really is.
In the first part, I will define nonlinearity and nonlinear dynamics. Specifically I will focus on a class called non-smooth dynamical systems. Then I will show how such problems can be effectively modeled and analyzed by low dimensional dynamical systems. The generic complexity of non-smooth dynamics will be demonstrated by a soft impact oscillator – an archetypal model for the high frequency vibro-impact drilling. The second part will be devoted to what we might call Nonlinear Dynamics for Engineering Design where I will present results from my recent projects, where nonlinear dynamic interactions have been used to enhance the performance of real systems and structures. I will put a special emphasis on one large project from oil and gas industry, where we have developed a revolutionary downhole drilling technology. I will argue that this would not be possible in a linear and static world!

Beginning fall 2013, Dr. C. “Nat” Nataraj, Professor and Chair of Mechanical Engineering, will assume the position of the Mr. and Mrs. Robert F. Moritz, Sr., Endowed Chair in Engineered Systems.
Established in October 2006 through a generous gift from Robert F. Moritz, Jr., DDS, VSB ’51, and his wife Diane, the Moritz Chair was created in recognition of the increasingly interdisciplinary nature of real-world engineering problems. In response, engineering educators must develop curricula to bridge the traditional boundaries among engineering major disciplines. The Moritz Chair supports the College’s mission to continually innovate within the undergraduate and graduate curricula in an effort to develop engineers who are better prepared to face these challenges after graduation.
I am honored to be recognized by Villanova for my contributions in research, teaching, and mentoring over the last three decades. This endowed position enhances the reputation of Villanova's research accomplishments and raises our profile in national and international collaborative efforts. I appreciate the confidence placed in me by bestowing this endowed position, and I will do everything to be worthy of the honor,” says Dr. Nataraj. “Such a position provides me with resources and time to pursue some truly wonderful educational and research challenges. It will also allow me to devote time and resources to write more books and monographs, in what I see as the next phase of my scholarly career.
