IVS 2018 Directing Board Elections
Nominees for At-Large Positions
This page provides information about the nominees for At-Large positions
on the IVS Directing Board. The nominees are listed alphabetically by their
family names. The At-Large members will be elected by the IVS Directing Board.
Aletha de Witt
Hartebeesthoek Radio Astronomy Observatory (HartRAO)
Aletha de Witt is an Operations Astronomer at HartRAO. She completed her PhD
in Radio Astronomy with a focus on celestial reference frames and calibrator
sources for VLBI. Her research is focused on fundamental astronomy, in particular
celestial reference frames. Alet is a principle investigator and scheduler for
some of the IVS Southern Hemisphere astrometric and geodetic VLBI sessions. Alet
has been part of the ICRF-3 IAU working group. The ICRF-3 was adopted at the
XXXth GA of the IAU in August 2018. Alet has recently been elected to the IAU
Commission on Astrometry. One of the goals of the ICRF-3 was the extension of
the ICRF to higher radio frequencies, such as K-band (22 GHz). Alet is the
principle investigator of the K-band celestial reference frame project. To date,
this project has received more than 600 hours of observing time on the VLBA
and equal amounts of time on Southern VLBI instruments. Since 2015, Alet has
been coordinating an annual month-long Newton fund AVN training program hosted
by HartRAO. Students from countries participating in the African VLBI Network
(AVN) receive training on topics such as radio astronomy and radio telescopes
as well as VLBI and geodesy.
David Hall
United States Naval Observatory (USNO)
David Hall began his involvement with the IVS and VLBI as an analyst with the
Fundamental Reference Frame Division at USNO in 1996. His duties were to perform
the USNO analysis on R1, R4, CRF, and INT1 sessions in addition to scheduling
CRF sessions. In 2006 he transferred to the VLBI operations division in the Earth
Orientation department at USNO to work on the Mark4 correlator. In addition to
acting as the correlator project manager he was responsible for managing the
CONT08 and CONT11 campaigns as well as overseeing the transition from the Mark4
to the DiFX correlator. He has been the chief of the VLBI Operations Division
since 2012 and served as the Correlators and Operation Centers Representative
on the IVS Directing Board since 2017.
Jinling Li
Shanghai Astronomical Observatory (SHAO)
Jinling Li has a PhD from the Chinese Academy of Sciences. He currently works as a
research professor at the Shanghai Astronomical Observatory. Jinling’s expertise is
in radio astrometry and space geodesy with emphasis in data analysis and technology
development. Just recently, Jingling has been involved in the technology development
of VLBI observation system for astrometry and geodesy as well as the further development
of the VLBI network in Shanghai.
Laila Løvhøiden
Norwegian Mapping Authority (NMA)
Laila Løvhøiden has been responsible for the operations of NMA's
geodetic observatory in Ny-Ålesund for the last year. In addition, Laila
is the Norwegian representative to the United Nations Global Geospatial Information
Management (UN-GGIM) Subcommittee on Geodesy. She is leading the governance work
in the subcommittee with the aim to strengthen the governance mechanism of the
global geodetic reference frame. As the Norwegian representative she was the co-chair
of the subcommittee until the end of November 2017, and participated in the
formulation and negotiation of the UN General Assembly resolution “A global geodetic
reference frame (GGRF) for sustainable development” (A/RES/69/266). Laila is an
experienced manager with a diversity of skills. Her educational background is a
Master in Engineering with an additional Master in Innovation and Technical Development.
Since 2012, Norway has spent M€30 to establish new twin telescopes for VLBI
as part of a complete core geodetic station in Ny-Ålesund. We are very concerned
at the moment that there is lack of VGOS correlation capacity in the world to process
the data from the newly established VGOS sites. This is something the IVS Directing
Board needs to focus on for the coming years, and NMA is confident that Laila has
the necessary competence to help bring this unfortunate situation a step in the right
direction.
Hiroshi Munekane
Geospatial Information Authority of Japan (GSI)
Hiroshi Munekane obtained a science degree in Geophysics from the University of Tokyo
in 2001. He has been working for the Geospatial Information Authority of Japan (GSI)
since then. He is now head of the space geodesy division at GSI and is leading the VLBI
group. His main research fields are noise evaluation of coordinate time series obtained
by various space geodetic techniques and signal extraction from them. Hiroshi was also
engaged in the investigation of seasonal vertical displacements of the Tsukuba 32-m
antenna as well as in the evaluation of a mapping function developed with a local
fine-scale numerical weather model.
Evgeny Nosov
Institute of Applied Astronomy (IAA) RAS
Dr. Evgeny Nosov has been working at the Institute of Applied Astronomy (IAA
RAS) since 2005. At present he heads an R&D laboratory working on various
equipment for radio astronomy: digital backends for VLBI and single-dish
applications, local oscillators and other parts for the receivers and signal chain.
His primary interest is the development of VLBI digital backends. He is the head
designer of R1002M DAS and BRAS systems that are currently in use at all
"Quasar" VLBI-network stations. At the moment he is working on Multifunctional
Digital Backend that allows to unify backends of all "Quasar" stations and provide
full compatibility of Russian stations with international networks, including VGOS.
Evgeny is a member of IVS, IAU, and the VTC.
Leonid Petrov
NASA Goddard Space Flight Center
Leonid Petrov received his Master degree in astronomy from Leningrad National
University in 1988 and obtained a Ph.D. from the Russian Academy of Sciences
in 1995. He worked at the Institute of Applied Astronomy on VLBI data analysis.
After his post-doc appointments at NASA Goddard Space Flight Center and the Geodetic
Institute of the University of Bonn, he has been working at NASA since 2000 on
various issues of VLBI data analysis, related geodesy, astronomy, and astrophysics
as well as processing space-borne GPS, outputs of numerical weather models, and
datasets of Earth observations from space. Petrov's current position is VLBI Lead
Scientist at NASA GSFC.
