She is noted for her work in identifying and studying brachiopods of the Ordovician period of the Paleozoic Era, and several have been named in her honor. Biernat worked at institutions of the Polish Academy of Sciences, published major works on brachiopods, participating in paleontological expeditions internationally, including leading a series of expeditions in the Arctic.

Early life and education Biernat was born Gertruda Skonieczna in Opole Lubelskie, in eastern Poland on March 17, 1923. She grew up in Starogard Gdański, northern Poland.

She would go on to author or co-author monographs and 16 papers. She also contributed book chapters, including co-authoring a chapter on mass extinction of brachiopods in Poland at the end of the Ordivician.

Despite political limitations of scientists' contact with the West for much of her career, Biernat participated in several international activities, including authoring a chapter in the 1965 Treatise on Invertebrate PaleontologyTreatise on Invertebrate Paleontology. She maintained friendships with Helen Muir-Wood and Sir Alwyn Williams. In 1959 Biernat was a member of a U.S. National Museum expedition in New York. In the 1970s, she initiated and led a series of paleontological expeditions to Spitsbergen in the Arctic.

In honor of her work identifying many brachiopods, three brachiopod genera have been named for her: Biernatium Havlíček, 1975 (Devonian orthide), Biernatella Baliński, 1977 (Devonian athyridide), and Biernatia Holmer, 1989 (Ordovician acrotretide).
