High success rate
in securing RGC GRF funds
Hong
Kong Research Grants Council (RGC, equivalent to NSF in US and NSFC in China)
and the PolyU every year spend a lot of resources and research funds in investing
and supporting academic staff and PhD students to conduct world-class
cutting-edge research. As of Jan. 2023, Dr. Liu has successfully 9
General Research Fund projects from the HK RGC, with a success rate 69.23%,
which is two times of the average success rate across all the universities in
Hong Kong. In addition, Dr. Liu has successfully secured research funds from
NSFC, PolyU, and other resources.
Many opportunities
for PhD Scholarship/Postdoc Fellowship/Research Associate/Research Assistant
applications
We always look for PhD/MSc/BSc students, Postdoc, Research
Associates, Research Assistants, Visiting Students, and Visiting Scholars to join this
innovative, dynamic group. Please contact Dr. George Zhizhao Liu: lszzliu@polyu.edu.hk for any inquiries.
The Micro-LARGE Lab has established a large network of international collaborations
with scientists from USA, Canada, Australia, Greece, UK, and Mainland China.

[Note to prospective MSc/MPhil/PhD Students,
Visiting Students, Postdoc Fellows]
The Micro-LARGE group
always (year-round)
looks for top excellent, self-motivated students and researchers who are striving for pursuing a post-graduate degree
(MSc., MPhil, or PhD) to join the group.
Premium full
scholarships will be offered to those successful applicants.
Please always contact
Dr. Liu (lszzliu@polyu.edu.hk) if you
want more information or have questions.
We are more concerned
with the following quality of applicants: Academic background, Publication
records, Computer language skills (e.g. C++, Matlab, Fortran), English language
skills, Inter-person communication skills.
For MSc/MPhil/PhD
students to register a degree at PolyU, the minimum English requirement is:
Applicants who have not obtained a degree from
an English-teaching university, the minimum English requirement is one of the
following:
(1)
an IELTS (International English Language Testing System) >=6.5
(writing component >=6.0), or,
(2)
a regular TOEFL (Test of English as a Foreign Language) score of
>=575, or,
(3)
a computer-based TOEFL (after 1998) score of >=232, or,
(4)
an internet-based TOEFL score of >=90, or,
(5)
other acceptable English test results, such as GRE (Graduate Record
Examination) or GMAT (Graduate Management Admission Test).
All English language test scores (TOEFL, IELTS
or others) are considered valid for five
years after the date of the test.
For the Visiting
Students and Postdoc Fellows, it is ideal to meet the PolyU’s minimum English
requirement.
Geomatics,
an incredibly critical technology in this information era!
In this world, scientists, engineers, researchers, and
actually many people are working hard every day to try to answer the following
6 most fundamental questions more correctly and more precisely:
1) When
2)Where 3) Who 4)What 5)Why 6)How
At present, we can easily answer “When” in a
completely numerical way because our time has been digitalized, for instance:
the UTC time at this point of writing is:2010-01-19 15:22:20. The numerical
expression of time is an important progress in human being history and it is
essential in this information era. So how about the other 4W1H questions? Can
you also use numbers to answer the remaining 4W1H questions? Answer is yes or
no. If you use Geomatics technology, you can answer the Where
numerically too. Without geomatics,
you can’t. Why? The answer is simple. For example, Hong Kong’s latitude and
longitude is: 22°20North, 114°11 East. So you can see the location
of Hong Kong can be easily described in numeric numbers. How to get these
numbers? It is a part of geomatics technology – using Global Positioning System
(GPS). With GPS, you may locate anywhere in the world numerically and display
it on your computer screen. This is the power and beauty of geomatics
technology – answering one of the world’s most fundamental questions “WHERE” in
a numerical way, a way people have never thought of and away that is so
critical in today’s information era.
With GPS technology, now any objects in our 4-dimensional
space-time domain can be completely digitalized and numerically stamped. This
is the contribution our geomaticians are making to the society.
The
Micro-LARGE is a Lab dedicated to the Research, Innovation, Development (RID)
in the area of satellite-based GNSS positioning and navigation, geomatics
engineering, atmosphere and climate observation and modeling. We use many
advanced instruments and techniques, such as Global Positioning System (GPS),
Global Navigation Satellite System (GNSS), remote sensing satellites and other
instruments.
The
Micro-LARGE is a resource-rich Lab that is well equipped to support the
innovation work conducted daily by our researchers, with plenty of research
fund (PhD scholarship), various datasets from worldwide, the world’s
state-of-art hardware instruments, software packages, research facilities,
external collaborations, and most importantly novel ideas.
The
excellence, impact and quality (EIQ) of research outcomes are our ultimate
pursuit, while quantity is our secondary consideration. We, the Micro-LARGE, are striving to the highest
level of excellence in teaching, research, and community service. It is our
destination goal to research and use the modern Geomatics technologies to
improve the living experience of the people worldwide.
We train
PhD students who truly love to conduct innovative cutting-edge research at a
first-class environment. We are active in publishing our research outcomes in
the top journals of our community.
