I am a Professor in the
department at the University of
in Ann Arbor, and I have a courtesy
appointment in the EECS
You can find my CV here.
My research interests lie in the area of control systems, and
I am a member of the
Robotics Group and the
College of Engineering.
My undergraduate degree is in
the University of Minnesota.
I did my M.S. and Ph.D.
at the University of California in
in the Intelligent
Machines and Robotics Laboratory.
As a graduate student, I had the opportunity to be a visiting scholar
at various places including: the
robotics group at
LAAS in Toulouse,
LSS at Supelec in Paris,
LIDS at MIT, and the
During my sabbatical leave in 2001-2002, I was an Academic
Visitor at the IBM T. J. Watson Research Center in
Hawthorne, NY in the
Group, and a Visiting Professor at ITIA, the Institute for Industrial
Technologies and Automation, in Milan, Italy. During the summer of 2003,
I was a summer professor intern at DaimlerChrysler in the Advance
Engineering group in Auburn Hills, MI. In May 2004, I taught a course (ME 360) at
Shanghai JiaoTong University
as part of the UM-SJTU cooperative
I am an alumna of the
Defense Science Study Group;

member of the Information Science and Technology
(ISAT) Study Group.
During my sabbatical leave in 2010-11, I was a Guest Professor in the Department of Automatic Control at Lund University in Sweden. I worked on the DIAdvisor project.

My research interests include control theory and applications in many different domains. Within the ERC for Reconfigurable Manufacturing
Systems, I have worked in the areas of logic control and networked control systems. We have a
Factory Testbed (RFT) on which we implement many of the control
methodologies that we develop. We published some of our testing results for
wireless networks in a Wireless Test Results Booklet.
As part of our manufacturing testbed, we use Simio simulation software
under a grant from Simio LLC (www.simio.com).
I was the director of the
Ground Robotics Research Center on
reliability of autonomous ground vehicles.
The robotics activities are now within the ARC, and I was Deputy
Director of the Automotive Research
Center (ARC) from 2011-2013.
My research includes developing methods to
improve reliability through reconfigurable control and enhanced
I am also helping to organize
the Robotics Initiative
within the College of Engineering.
I previously worked with colleagues at IBM in the application of control theory
to computing systems, see our book on Feedback Control of
Computing Systems. I have also done some work in nonlinear control,
both theory and applications, looking at problems of trajectory generation
and stabilization for nonlinear systems, and applications to such systems
as a helicopter and mobile robots.

ASME Dynamic Systems and Control Division
From July 2010 through June 2011, I was the Chair of the DSCD.
Mentoring and Networking Workshop for Junior Women Faculty in the Big 10
In April 2010 and 2013, I co-organized the Big 10 Women's Workshop in Milwaukee. The purposes of the workshop were to provide a professional networking opportunity,
cultivate peer collaboration and mentoring relationships, and foster interactions between junior women faculty and senior women faculty role models.
ASME-DSC Conference 2008
I was on the organizing committee for the first Annual ASME
Dynamic Systems and Control
Conference, held in
Ann Arbor, October 20-22, 2008.
I co-organized the 8th International Workshop on Discrete Event Systems
(WODES), held in
Ann Arbor, July 10-12, 2006. Check the website for photos of the
conference, banquet, and dinner trek.
Workshop on Logic Control
In June 2000, I co-organized a Workshop on Logic Control for
Manufacturing Systems, which brought together industry practitioners
and academic researchers to discuss problems and solutions. One of the
outcomes of the workshop was a list of the Top 10 Challenges in Logic Control for
In conjunction with teaching ME461, I developed a set of web-based
tutorials to introduce students to the use of Matlab for the design and
analysis of control systems. These tutorials won an Undergraduate
Computational Science Award from the US Department of Energy through the
Ames Laboratory, and the Educom Medal,
nominated by ASME. The NSF supported the
original development these tutorials. An updated (for Matlab 5) and
expanded (to include Simulink tutorials) version of the tutorials was
published by Addison-Wesley (now Prentice Hall) in 1999.
The tutorials were completely updated in 2012 by Professors Bill Messner
and Rick Hill.

When I taught Linear Systems Theory (ME 564/EECS 560/Aero 550) in Fall 2012
I asked the students in class to create videos about some of the concepts
we covered. The purpose of the video assignment was for students to get
to know some other students in class. Some of the videos have been posted to YouTube,
