and graduate research projects in advanced wireless and
applications (e.g., 5G and beyond wireless systems, AR/VR,
connected and automated vehicles, and cyber-physical-human
systems in general) are available. We may also have postdoc
and research scientist positions once in a while. If
interested, please contact Prof. Hongwei Zhang at "firstname

to each email inquiry, but I do read each inquiry.)
Prospective Students & Scholars:
Our research interests lie in the theory and practice of
wireless networked cyber-physical-human systems, with a
special focus on the modeling, algorithmic, and systems issues
in wireless sensing and control networks as well as their
applications in augmented reality (AR)/virtual reality (VR),
connected and automated vehicles, smart grid, Industry 4.0,
smart agriculture, and IoT as well as cyber-physical-human
systems in general.
Before contacting me, please check out the following

focusing on high-quality research, and by collaborating with
other research groups in academia and industry, our research
program provides students with access to world-class
facilities, real-world experience, and ample opportunities
of contributing to research and innovation.
As a 400+ acre development and having over 96 tenants
employing over 2,250 people, the ISU
Research Park hosts a vibrant startup community as
well as R&D branches of major companies such as John
Deere. In addition, many other established and start-up
companies (e.g., Rockwell-Collins) are within 100 miles from
ISU campus and are leaders in wireless communication and
networking, AR/VR and control systems, and their
applications in various domains.

I may only fund Ph.D. students who are dedicated to high
quality research. Preference will be given to students who
have strong academic background (in
computer science, computer engineering, electrical
engineering, or related disciplines such as mathematics
and statistics), are self-motivated and
goal-oriented, and can take initiative in executing research
visions. Experience in systems building, mathematical
modeling, and/or research will be a plus. Funded students

who have strong systems building capabilities and will enjoy
the challenges and excitement of conducting game-changing
research. If you are an undergraduate student, you may
consider checking out ISU
Undergraduate Research Program and the McNair Program.

mathematical modeling problem] Faster QuickPass System
systems are increasingly appearing to reduce people's time
waiting in line, whether it is at tollbooths, amusement
parks, or elsewhere. Consider the design of a QuickPass
system for an amusement park. The amusement park has
experimented by offering QuickPasses for several popular
rides as a test. The idea is that for certain popular rides
you can go to a kiosk near that ride and insert your daily
park entrance ticket, and out will come a slip that states
that you can return to that ride at a specific time later.
For example, you insert your daily park entrance ticket at
1:15 pm, and the QuickPass states that you can come back
between 3:30 and 4:30 pm when you can use your slip to enter
a second, and presumably much shorter, line that will get
you to the ride faster. To prevent people from obtaining
QuickPasses for several rides at once, the QuickPass
machines allow you to have only one active QuickPass at a
have been hired as one of several competing consultants to
improve the operation of QuickPass. Customers have been
complaining about some anomalies in the test system.
For example, customers observed that in one instance
QuickPasses were being offered for a return time as long as
4 hours later. A short time later on the same ride, the
QuickPasses were given for times only an hour or so later.
In some instances, the lines for people with Quickpasses are
nearly as long and slow as the regular lines.
problem then is to propose and test schemes for issuing
QuickPasses in order to increase people's enjoyment of the
amusement park. Part of the problem is to determine what
criteria to use in evaluating alternative schemes. Include
in your report a non-technical summary for amusement park
executives who must choose between alternatives from
competing consultants. [back]
the above problem is extracted from the 2004 Mathematical
Contest in Modeling organized by The
Consortium for Mathematics and its Applications.

Typically, "rock" tasks tend be
those that may not seem urgent all the time but requires
regular, persistent effort over longer periods, and that, if not
addressed with a longer-term and persistent strategy and effort,
may well become "urgent" by the deadline in addition to always
being important; "sand" tasks tend to be those that may seem
urgent and, given that they also tend to be relatively easier to
complete, can offer immediate "reward", which makes them even
more attractive for us to treat them as potentially more urgent
than what they really are; "pebble" tasks tend to be those in
between. So, enjoying sorting out our rocks, pebbles, and sand!
