IVS 2020 Directing Board Elections
Candidates for Representative Positions
This page provides information about the candidates for representative positions
on the IVS Directing Board. Within each category candidates are listed alphabetically
by their family names. The Representatives will be elected by the Associate Members.
Candidates for Networks Representative
Karine Le Bail
Karine Le Bail graduated in "Fundamental Astronomy, Celestial Mechanics and Geodesy" at
the Paris Observatory in 2000 where she worked on the ICRF and source stability as a
thesis project. She then got her PhD in Space Geodesy / DORIS at the LAREG/IGN - Paris
Observatory. Her follow-up post-doc was funded by the CNES to assist the IDS Analysis
coordinator which took her to the NASA Goddard Space Flight Center. After ten years
in the DORIS community and the submission of a GSFC DORIS contribution to the ITRF2008,
she worked for NVI, Inc. at NASA GSFC for eleven years in VLBI. She has been involved
in various activities in the IVS community, as technique development, scheduling and
ICRF work. Karine recently integrated into the Space Geodesy and Geodynamics group at
Chalmers University of Technology as a Senior Researcher and is active for the IVS
network station and the IVS analysis center at the Onsala Space Observatory.
Yu Takagi
After obtaining his Ph.D. in Geophysics from the University of Tokyo, Yu Takagi has been
working for the Geospatial Information Authority of Japan (GSI). He has been involved in
the maintenance of the Japanese geodetic reference frame and, in 2020, became the chief
of operations of the Tsukuba Correlator and Analysis Center. In the GSI VLBI Group he is
responsible for management tasks such as funding, planning, and addressing any technical
problems. He is the de facto head of the VLBI Group. Besides VLBI observations, GSI has
historically contributed to the construction of the ITRF with local tie surveys, and Yu
is familiar with the sophisticated survey technique. With this background, he became the
representative of technology in VLBI in the Global Geodetic Observing System (GGOS) in
Japan and he is a member of the IVS Observing Program Committee. Yu is now one of the key
persons not only in the GSI VLBI group but also in the Japanese VLBI community.
Pablo de Vicente
Pablo de Vicente has been involved in VLBI operations since 1992 and was deeply involved
in starting VLBI observations, both for Geodesy and Astronomy, in Yebes and since then he
has been managing VLBI operations (including software development) until 2017 when he
became director of the Observatory of Yebes. Pablo has been the EVN Technical and Operations
Group chair for 4 years (2015 to 2019) and he has experience coordinating a technical VLBI
group from different countries.
Candidates for Analysis and Data Centers Representative
Anastasiia Girdiuk
Anastasiia Girdiuk has dealt with the VLBI technique since her studies at Saint Petersburg
State University (SPBU). She received her specialization in astronomy from SPBU in 2013 and
her PhD in geodesy in 2017 from Vienna University of Technology (TU Wien). Both works were
dealing with different aspects of the VLBI technique. While the first study works with
scheduling of the VLBI observations, the PhD thesis represents thoughtful reprocessing of
the VLBI data set to evaluate the high-frequency ERP variations. In 2018, Anastasiia
has joined the IVS Analysis Center at BKG. She participates actively in routine analysis
and in ongoing ITRF2020 activities. Besides routine session analysis and product delivery
to the IVS community, her work is also focused on establishing internal routine data
processing for operational BKG activities to support vgosdb structure. In addition to
the VLBI Analysis Center activities, Anastasiia is taking part in BKG's IVS Data Center
operations as well, initially with the focus on all aspects related to optimal handling
of vgosdb. A few months ago, Anastasiia became the head of the IVS Data Center at BKG
and is working in close cooperation with other IVS Data Center representatives in order
to re-establish the full mirroring process including the sessions in vgosdb. Anastasiia
has gained a comprehensive experience in the complexity of Analysis and Data Center tasks.
At work, her agenda along with the BKG concept is to make geodetic data and products, in
particular VLBI-based data and products, well-described, efficiently provided and broadly
represented among interested communities. BKG-internally, Anastasiia is also linked with
the colleagues working on the establishment of an inter-technique combination, where she
is focused on providing an optimal input based on VLBI data.
Leonid Petrov
Leonid Petrov got Master degree in astronomy from Leningrad National
University in 1988 and Ph.D. from the Russian Academy of Sciences
in 1995. He worked in the Institute of Applied Astronomy on VLBI
data analysis, then had post-doc appointments at NASA GSFC and Geodetic
Institute of Bonn University, and then he has been working at NASA since
2000 on a broad range of problems related to VLBI data analysis, geodesy,
astronomy, and astrophysics, as well as processing space-borne GPS,
utilizing outputs of numerical weather models, and datasets of Earth
observations from space. Leonid Petrov is maintaining a number of software
packages and Internet services. The current position is VLBI Lead Scientist
at NASA GSFC. He has published 50 refereed journal papers on analysis of VLBI
results. Number of citations: 1718. Hirsch index: 23.
Oleg Titov
Dr Oleg Titov has been working in the field of geodetic VLBI since 1992.
His career has seen him contribute to the operations of three
IVS Analysis Centers as detailed below. Oleg continues to focus on advancing
fundamental VLBI analysis techniques. In 2006, Oleg helped develop a business case
for fast-slewing radio telescopes for the IVS geodetic program and subsequently he
was a key proponent of the AuScope VLBI project which led to the construction of three
fast-slewing radio telescopes in Australia. A focus of his work has been contributions
to the ICRF frames (ICRF2 and ICRF3) with individual catalogs produced by the software
package OCCAM. He has authored many papers on VLBI data analysis.
