Jongeun Choi received his Ph.D. and M.S. degrees in Mechanical
Engineering from the
University of California at Berkeley in 2006 and 2002 respectively. He
also received a B.S. degree in Mechanical Design and Production
Engineering from Yonsei University at Seoul, Republic of Korea in 1998.
He is currently an Associate Professor with the Departments of
Engineering and Electrical and Computer Engineering
at the Michigan State University.
His current research
interests include systems and control, system identification, and Bayesian methods, with applications to mobile
robotic sensors, environmental adaptive sampling, engine control, neuromusculoskeletal systems,
and biomedical problems. He is an Associate Editor for Journal of
Dynamic Systems, Measurement and Control. His papers
were finalists for the Best Student
Paper Award at the 24th American Control
Conference (ACC) 2005 and the Dynamic System and Control Conference
(DSCC) 2011 and 2012. He is a recipient of an NSF CAREER Award in 2009. Dr. Choi

- Distributed learning and cooperative control of multi-agent systems: Currently, we are
developing a network of collaboratively

environment collaboratively with neighboring vehicles to achieve a
We are developing environmental adaptive sampling algorithms for
mobile sensor networks to predict scalar fields of interest using Gaussian processes and kernel regression techniques.
The pilot research was supported by Intramural
Research Grants Program in Michigan State University. This project has been funded by an NSF CAREER Award. (See some simulation pictures).
- Modeling and control of musculoskeletal systems: The goal
is to apply concepts from modern control theory to model and analyze
the neuromuschular control systems in order to
generate useful information for the treatments. This project has been funded by an NIH center grant, "Systems Science Center for Musculoskeletal CAM Therapies." See more information at Center for Orthopedic Research. See also MSU news. Another topic is to study the evolution and adaptation of biological systems
under various environments.
- Patient-specific calibration of computer models via a Bayesian method: The goal of this project is to make prediction and gauge its
uncertainty in the computer models for a patient (such as a growth and remodeling model) from observations and various
uncertainties such as measurement noise, estimation errors, and
biological variability. This research has been supported by an NIH R01 grant with a project title:
Growth and Remodeling Model of Abdominal Aortic Aneurysm: Toward
Clinical Applications. See more information in ME news.
- Energy-efficient engine control technology:
In this project, we obtain an event-based sampled discrete-time linear
system to represent a port-fuelinjection process based on wall-wetting
dynamics, and formulate it as a linear parameter varying (LPV) system.
The system parameters used in the engine fuel system model are engine
speed, temperature, and load. These system parameters can be measured
in real-time through physical or virtual sensors. Gain-scheduling
controllers for the obtained LPV system have been designed based on the
numerically efficient convex optimization or linear matrix inequality
(LMI) technique. The simulation results demonstrate the effectiveness of the proposed energy-efficient engine technology.
- Parameter estimation and system
reduction techniques have been developed to simplify robust
and adaptive controller design. Parameter estimation and system id
techniques have been applied to various biomedical and NDE problems
such as mechanical behavior of arteries, MRI for skin
microcirculation, and wavelet transformed ultrasonic signals.
multidisciplinary research team at Michigan State University is looking
for a Ph.D. student who will be responsible for modeling, system
identification, and control design of human (neuro-)musculoskeletal
systems using the data collected from various human subject experiments.
The RA position will be funded by an MSU NIH center: Systems Science Center for Musculoskeletal CAM Therapies. See more detail information on the project at the following links: http://orthopedicresearch.msu.edu/msunih.aspx
Ph.D. student must have a strong background in system identification
and control theory with a motivation on the biomedical project. A
student with additional prior exposure to biomechanics, convex
optimization, and machine learning is highly valued. The selected student will start from either Fall 2014 or Spring 2015 in mechanical engineering at MSU. Please contact and send your CV to Professor Choi (via email) for the open RA position.
