Dr. Paulina KarczmarekDr. Paulina Karczmarek received her PhD in 2019 from Astronomical Observatory of Warsaw University, Poland. She joined Astronomy Department in May 2019 as an ERC (European Research Council) postdoctoral fellow and she works with professor Wolfgang Gieren within the Araucaria Project. Paulina explores how binarity among standard candles, like Cepheids and RR Lyrae stars, affects distance determinations based on period-luminosity relations. Her research is a part of the Araucaria Project, whose main goal is to refine the extragalactic distance scale using various standard candles. In her research she uses three main methods: she conducts astronomical observations in La Silla and Armazones in near-infrared and visual domains, creates synthetic populations of binary stars, and works on particular binary systems with pulsating stars using evolutionary code MESA. Apart from science, she's keen on widening her horizons by traveling, hiking, cycling and long conversations.
