Rifat Sipahi

About

Sipahi received his BS from Technical University of Istanbul in 2000, and MS and PhD degrees respectively in 2002 and 2005 from University of Connecticut, all in mechanical engineering. Awarded with a Chateuabriand scholarship by the French government, he has been a postdoctoral fellow at Universite de Technologie de Compiegne, HeuDiaSyC Labs (CNRS) in France. He joined the Department of Mechanical and Industrial Engineering at Northeastern University in August 2006 where he is currently a Professor and Associate Chair for Research Affairs.

Sipahi is the recipient of the 2015 ASME Dynamic Systems and Control Division Outstanding Young Investigator Award, a 2011 DARPA Young Faculty Award, 2022 College of Engineering Outstanding Faculty Service Award, 2014 College of Engineering Faculty Fellow Award, and 2011 College of Engineering Martin W. Essigmann Outstanding Teaching Award. He has also been actively involved in ASME Dynamic Systems and Control (DSC) Division, taking editorial duties in division newsletter and recently in division-led ASME DSC Magazine. His scholarly activities include publication of 79 journal articles and 98 peer-reviewed conference papers, as well as 10 book chapters and additional 37 conference presentations including invited session talks. He has received funding for research and/or education from the US National Science Foundation, DARPA, DEVCOM, Army Research Labs, Air Force Research Labs, NIH, DOE, CIMIT. He (co-)edited four book volumes with Springer, each with a collection of invited chapters totaling around 400 pages (2009, 2012, 2014, 2019), total of which received over 200,000 accesses to date according to Springer. His Google Scholar h index is 37.

Sipahi has been actively involved as associate editor, associate editor at large, publicity chair, finance chair, exhibits/sponsors chair, outreach chair, program committee member, session chair/co-chair in many conferences organized by ASME, IEEE, and IFAC, including Editor of the Conference Editorial Board of the ASME Dynamic Systems and Control Conference (2018-2019), co-chair of 2022 IFAC Workshop on Time Delay Systems, and the 2012 IFAC Workshop on Time Delay Systems, which he co-organized at Northeastern University, and of which he was the Program Editor. He is also the co-creator of e-delay newsletter together with Prof. Niculescu. He was the lead organizer of three one-full-day educational workshops with Professors Hitay Ozbay, Silviu-Iulian Niculescu, Wim Michiels, Dimitri Breda, and Fatihcan M. Atay in the field of Time Delay Systems at three major control systems conferences (2013, 2014 European Control Conference, and 2013 IEEE Conference on Decision and Control) as well as the sole organizer of a similar workshop held preceding the ASME Dynamic Systems and Control Conference in 2015. He is the lead author of the article entitled Stability and Stabilization of Systems with Time Delay, Limitations and Opportunities that was published in 2011 in IEEE Control Systems Magazine, with S.-I. Niculescu, C.T. Abdallah, W. Michiels and K. Gu as co-authors; the author of the book entitled Mastering Frequency Domain Techniques for the Stability Analysis of LTI Time Delay Systems (2019, Society of Industrial and Applied Mathematics); and co-author in an article in Nature Human Behaviour (2019).

Sipahi is a Fellow of ASME since 2014 and was elevated to IEEE Senior member grade in 2016. He currently serves as Associate Editor for Automatica.
