IVS 2024 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.

Simone Bernhart
Simone Bernhart MPIfR and BKG/Reichert GmbH
Simone Bernhart studied Physics and (Radio)Astronomy at the Rheinische Friedrich-Wilhelms-Universität Bonn and worked on her diploma and PhD theses in the VLBI group at the Max-Planck-Institute for Radio Astronomy until completion in 2010. During her doctorate in 2007, she started working in the geodetic VLBI group at the Bonn Correlator taking care of experiment supervision, e-transfer, and media shipment. Simone is currently the Lead of the geodetic VLBI group of the Bonn Correlator. She made it her mission to bridge the gap between stations, correlators, and analysts to have a smooth transition to the VGOS era.

Masafumi Ishigaki
Masafumi Ishigaki Geospatial Information Authority of Japan (GSI)
After obtaining a master's degree in astrophysics from the University of Tokyo, Masafumi Ishigaki started his career in the Geospatial Information Authority of Japan (GSI) as a staff member of the Tsukuba VLBI Correlator and Analysis Center. He was engaged in VGOS observations and contributed to the scheduling and observing of the AOV sessions as the chief of the VLBI observation section. He stayed at Onsala Space Observatory in Sweden for one year as a guest researcher working on the VLBI scale in ITRF2020. He is currently in charge of the management of the VLBI service at GSI. He has been a member of the IVS Directing Board and the IVS Observing Program Committee since 2023.

Hana Krásná
Hana Krasna Vienna University of Technology (TU Wien)
Hana Krásná received her PhD in Geodesy from the TU Wien, Austria, in 2013, with a thesis on Estimation of solid Earth tidal parameters and free core nutation with VLBI. She has extensive experience in VLBI data analysis, having been one of the main developers of the geodetic VLBI analysis software package VieVS since its inception in 2008. Hana covers the areas of theoretical modeling of the group delay, least-squares adjustment and combination of individual VLBI sessions at the normal equation level to the global solution, and the construction of VLBI reference frames. She is experienced in the analysis of legacy S/X data, VGOS measurements, and is also actively exploring the potential of VLBI data at higher radio bands for geodesy and astrometry. Hana has been an Associate Member of the IVS since 2008. In her current position as Assistant Professor at the TU Wien and Head of the IVS Analysis Center in Vienna, she leads investigations on systematic errors in reference frames and Earth orientation parameters, and is routinely involved in the operational analysis of the IVS sessions.

Fengchun Shu
Fengchun Shu Shanghai Astronomical Observatory (SHAO)
Fengchun Shu is a research scientist at SHAO. He developed a scheduling/modeling software tool dedicated to real-time VLBI application for navigation of China's Lunar probes. He has been active in the IVS since 2011. His activities included making Seshan25 available for IVT-INT-3 sessions, pushing the Shanghai Correlator into IVS operations, and contributing to the foundation of AOV. He has scheduled many AOV/APSG sessions since 2015, emphasizing high-sensitivity astrometry of weak radio sources and precisely locating new stations. He led the Shanghai Correlator operation team to correlate more than 210 IVS sessions, with frequent interaction with a lot of international stations. He helped to develop a standard data processing pipeline for K-band geodesy of the East Asian VLBI Network. He has been instrumental in preparing new VGOS stations at Shanghai, Urumqi, and Chiang Mai for IVS observations. He has been the AOV Chair for the past 5 years and is a current at-large member on the IVS Directing Board.

Nataliya Zubko
Nataliya Zubko Finnish Geospatial Research Institute (FGI)
Nataliya Zubko obtained her PhD in Applied Physics from Hokkaido University, Japan, in 2009. Since 2010, she has been a specialist researcher at the Finnish Geospatial Research Institute, focusing on VLBI techniques. She has been involved in operating IVS sessions with the legacy Aalto University radio telescope. After securing funding for a new VGOS telescope, she was responsible for the construction of the new system at Metsähovi station. Nataliya Zubko has actively contributed to various IVS activities, including organizing IVS General and EVGA meetings and IVS training schools. Her research aims to enhance the performance of the new VGOS system by addressing radio source structure issues and investigating VGOS systematic errors.
