Bonanos Alceste
(P.I.)
bonanos [at] noa [dot] gr
NASA/ADS list
Alceste obtained her B.A. in Physics and Astronomy from Wellesley College (USA) in 2000, her M.A. in Astronomy from Harvard University (USA) in 2002 and her PhD in Astronomy from Harvard University (USA) in 2005. She was a Vera Rubin Fellow at the Carnegie Institution for Science (USA) from 2005-2008, and a Giacconi Fellow at the Space Telescope Science Institute (USA) from 2008-2009. She joined IAASARS, National Observatory of Athens, in September 2009 and since March 2017 is a Senior Researcher.
Research Interests: Observational Extragalactic Stellar Astrophysics, with emphasis on massive stars and the extragalactic distance scale. She has been working mainly on problems related to massive stars in nearby galaxies, stellar variability and near-earth objects.
Grigoris Maravelias
(Postdoc)
maravelias [at] noa [dot] gr
NASA/ADS list
Grigoris graduated from the School of Applied Mathematics and Physical Sciences of the National Technical University of Athens (Greece) in 2004. After the completion of his MSc from the University of Crete in 2007, he served as a laser technician at the Foundation for Research and Technology-Hellas (FORTH, Greece). In 2010, he succeeded in acquiring funding from the State Scholarship Foundation of Greece that allowed him to obtain a PhD in Astrophysics from the University of Crete in 2014. Then, he moved on to work as a Postdoctoral Researcher at the Astronomical Institute of the Czech Academy of Sciences (Czechia, 2014-2016), the Universidad de Valapaiso (Chile, 2017), and at the University of Crete and FORTH (Greece, 2017-2018). Since September 2018 he is employed at IAASARS-NOA, working on the ASSESS project.
Research Interests: Observational Astrophysics, with a focus on massive stars, X-ray binaries, variable stars, circumstellar matter, stellar populations in other galaxies, exoplanets. Other interests include Machine-learning applications, Professional-Amateur networking and collaborations, and Openness in Astronomy.
Frank Tramper
(Postdoc)

NASA/ADS list
Frank obtained his BSc (2008), MSc (2010), and PhD (2014) in Astronomy & Astrophysics at the Anton Pannekoek Institute for Astronomy of the University of Amsterdam. Following his PhD he remained in Amsterdam for a PostDoc of one year. In January 2016 he obtained a 3 year research fellowship from the European Space Agency, and was based at ESA’s European Space Astronomy Centre near Madrid. Since January 2019 he is a Postdoctoral Researcher at IAASARS, working on the ASSESS project.
Research Interests: The spectroscopic study of massive stars in their various stages of evolution (e.g., O-type, Luminous Blue Variables, Wolf-Rayets). Areas of particular interest are the effect of metallicity on the physical properties of these stars and their stellar winds, and stars in their most advanced evolutionary stages.
Ming Yang
(Postdoc)
myang [at] noa [dot] gr
NASA/ADS list
Ming obtained his B.Sc. in Astronomy in 2006 from the Department of Astronomy, Beijing Normal University and his M.Sc. in Astrophysics from the same institute. In 2012, he obtained his Ph.D. in Astrophysics also from the same institute. The title of the dissertation was: “The Infrared Properties and Period-Luminosity Relations of Red Supergiant Stars in the Magellanic Clouds”. In 2012-2015, he was a LAMOST Fellow and support astronomer at the National Astronomical Observatories of the Chinese Academy of Sciences working for the LAMOST survey. Since June 2015, he is a postdoctoral researcher at the National Observatory of Athens, participating in the ESA project “Hubble Catalog of Variables”.
Research Interests: The physical properties of intrinsically variable stars, the pulsation and oscillation of late-type stars, infrared properties of evolved stars and their dust, asteroseismology of sun-like and massive stars, astrostatistics, star formation in nearby/high-redshift galaxies, galaxy formation and evolution, identification and kinematic analysis of galaxy cluster.
Stephan de Wit
(PhD student)

NASA/ADS list
Stephan is a Dutch student, who received a Bachelor degree in Physics & Astronomy in 2016 at the Anton Pannekoek Institute of Astrophysics (API) at the University of Amsterdam. In 2018, he received a Masters degree under the supervision of Prof. de Koter from the API institute. The title of his MSc thesis was “Characterising the properties of the VFTS 176 binary in the 30 Doradus starburst region”. As of March 2019, Stephan joined the ASSESS team under supervision of Dr. Bonanos, to help ‘assess’ one of the outstanding questions in astrophysics: the role of episodic mass loss in evolved massive stars. He is registered as a PhD student at the University of Athens.
