Postdoctoral Researcher

Following his Ph.D., Lankeswar briefly worked at the National Centre for Radio Astrophysics (NCRA), India, before joining West Virginia University (WVU) as a Postdoctoral Fellow in September 2022. At WVU, he was an active member of the NANOGrav collaboration, contributing to pulsar timing array research. In September 2025, he joined the Institute of Astrophysics, Foundation for Research and Technology–Hellas (IA-FORTH), as a Postdoctoral Researcher on the MMMonsters project, focusing on the first multi-messenger detection of a supermassive black hole binary in collaboration with Maria Charisi.

After his PhD he worked as  postdoctoral fellow at the Università degli Studi di Cagliari (Italy). Alongside academia, he has worked as a computer scientist in several private-sector technology companies. In February 2025 he joined the group of  Carolina Casadio, where he contributes to the ERC-funded project SMILE – Search for Milli-lenses to Discriminate Between Dark-Matter Models.

Ethan has designed and led multiple AGN monitoring campaigns in the X-rays, using the Neutron Star Interior Composition Explorer (NICER) to provide daily spectral monitoring of nearby Seyfert 1 galaxies. In October of 2024, Ethan began a postdoctoral research position at IA-FORTH, working on the “MMMonsters: The first multi-messenger detection of a supermassive black hole binary” project with Maria Charisi.

He has done a first post-doc at SISSA in Trieste on the data analysis group with Roberto Trotta in 2020, then he joined the Instituto de Astrofisica de Canarias in Tenerife, Canary Island as a member of Euclid in 2020/2021 with Helmut Dannerbauer and Carlos Gutierrez. In 2023, he joined a project outside of astrophysics to work as a research engineer on oceanography in LIENSs in La Rochelle (France) with Mélanie Becker. Since 2024, he has been a postdoctoral researcher at FORTH under the supervision of Jean-Luc Starck and Panagiotis Tsakalides in the TITAN team.

Her thesis work focused on the study of the disk of the Milky Way disk at different scales taking insights from the distribution of red clump stars and open cluster polarimetry. During her doctoral studies, she conducted optical linear polarization observations of open clusters utilizing Indian observational facilities to trace line-of-sight dust distribution. She joined the Institute of Astrophysics-FORTH as a post-doctoral Fellow in the PASIPHAE project in April 2024.

After a six-months appointment at the Center for Astrophysics | Harvard & Smithsonian (Cambridge, MA, USA) in 2011 as a visiting scientist under the supervision of Dr. G. Fabbiano, he worked as a post-doc work at the Center for Astrophysics | Harvard & Smithsonian, first under the supervision of Dr. G. Fabbiano to study the multi-wavelength emission of AGN (2011-2014), and then under the supervision of Dr. D.-W. Kim, studying the extended X-ray emission in galaxies and developing pipelines for spectral and imaging analysis of X-ray data (2014-2016). After another six-months appointment as a visiting scientist in 2017 at the Center for Astrophysics | Harvard & Smithsonian under the supervision of Dr. D.-W. Kim, he worked at the University of Turin (Torino, Italy) as a post-doc under the supervision of Prof. F. Massaro and at the Astrophysical Observatory of Turin (Pino Torinese, Italy) as an AstroFIt2 fellow under the supervision of Dr. C. Raiteri, to study the large scale environment and the extended emission of radio sources and unidentified gamma-ray sources, and the multi-wavelength variability and polarization of blazars (2017-2023). Since March 2024, he has been a postdoctoral researcher under the supervision of Dr. Y. Liodakis in the BOOTES project.

After her PhD, she moved to University of Liège (Belgium) with a IAC-KULeuven Postdoctoral Fellowship (2017-2019) followed by a postdoctoral contract (2019-2021) in the same University. In 2021, she got a "Junta de Andalucía" fellowship (2021-2024) to develop her research at the "Instituto de Astrofísica de Andalucía" (Spain). In March 2024, she has joined the BOOTES ERC project at IA-FORTH.

Since January 2024, she has been a postdoctoral researcher under the supervision of Dr. J-L. Starck and Prof. P. Tsakalides in TITAN, a collaborative project between the Institutes of Computer Science and Astrophysics of FORTH.

During his doctoral studies, Dimitris spent one year and a half supporting operations on the 2.5m Isaac Newton telescope (INT), one of the many telescopes at the Observatorio del Roque de Los Muchachos (La Palma), while the last 6 months he was one of the trainers of the next-generation of INT support astronomers. Since Fall 2023, he joined the SFERICSS project as a Postdoctoral researcher at the Institute of Astrophysics - FORTH.

In 2019 he moved at the Observatory of Geneva (Switzerland), in the group of Tassos Fragkos, as a postdoc, partially funded from the Swiss Government Excellence Scholarship. In 2022, he moved at the National Observatory of Athens in the ERC-funded group of Alceste Bonanos, ASSESS. ince Fall 2023, he joined as a Postdoctoral HFRI (ELIDEK) Fellow at the Institute of Astrophysics, - FORTH, as the PI of the SFERICSS project.
