It is with great sadness that we announce that BPS Council member Anita Niedziela-Majka (1969–2024) died on December 3, 2024, at the age of 55. Anita was diagnosed with invasive breast cancer shortly after being elected to BPS Council in 2023. She was a member of the Macromolecular Machines & Assemblies Subgroup.
Anita was born on October 5, 1969, in Bierawa, near Kędzierzyn-Koźle, in southwest Poland. She attended high school there, where her interest and fascination with science started. Her father was an engineer, and her mother was an administrative assistant. Anita’s interests in quantitative sciences (initially astronomy) led her to pursue an MSc in biotechnology and PhD in biochemistry and organic chemistry at Wrocław Technical University (Poland), where she did some groundbreaking work on nuclear receptors. Anita met Jurek Majka in college, and they married in 1993. Anita was a stimulating colleague and teacher there, remembered for her rigorous science and teaching skills. Those who knew her recall a warm and generous friend and describe her as “one of the most inspirational, dedicated, and genuinely wonderful people we have had the privilege of knowing. We can think of no one who better exemplifies the values of academic excellence and scientific impact.” Anita obtained her PhD in 1999 after defending her thesis titled ”Recombinant DNA Binding Domains of Ecdysteriod Receptor—Purification and Characterization of DNA Binding Properties.”
In 1999, Anita and Jurek moved to the United States, where she brought all of her outstanding qualities to pursue her first post-doctoral position in the Department of Biochemistry and Molecular Biology at Saint Louis University (SLU), working in the laboratory of Tomasz Heyduk. At SLU, she worked on mechanisms of transcription initiation in bacteria. She developed some unique fluorescence approaches that produced novel insights into the energetics of this process and conformational changes involved in its regulation. She is remembered by her former SLU colleagues as always full of positive energy and enthusiasm for the next experimental challenge.
In 2002, Anita undertook a second postdoctoral position in the Department of Biochemistry and Molecular Biophysics at Washington University in St. Louis School of Medicine, working in the lab of Tim Lohman. There, Anita carried out mechanistic studies on the superfamily 1A helicases and translocases UvrD, Rep, and PcrA by using a wide range of biophysical and biochemical approaches (fluorescence stopped-flow, quenched-flow, and analytical ultracentrifugation) to sort out the functional roles of their different assembly states. Anita excelled in so many areas, from protein expression and purification to thermodynamics and transient-state kinetics. Anita was a delightful person to have in the lab, both as a scientist and as a person, and she was always willing to tackle any problem, no matter how tough. She always made the laboratory a fun place to be and was always willing to assist her lab mates at a moment’s notice, always with a smile.
In 2007, Anita moved to Gilead Sciences, Inc. as a senior biology research scientist, and continued there until her death. At Gilead she used her biophysical expertise to contribute to many areas of research, including assay development and studies of macromolecular interactions and self-assembly processes. Anita was part of multidisciplinary teams developing small-molecule drugs against HIV and HCV therapy targets, as well as anti-inflammatory and anti-cancer therapeutic approaches. Her collaborative spirit, problem-solving instincts, and interests in teaching and mentoring served her well in these endeavors. Outside the lab, Anita and Jurek enjoyed hiking, cooking, and birdwatching all over the country.
Anita left us too soon. She was a wonderful scientist, colleague, and friend. We miss her greatly.
