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.

[August 29, 2016] 2017 Hong Kong PhD Fellowship (Annually
available)
[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.
