Key takeaways

Jan Poleszczuk belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jan Poleszczuk to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jan Poleszczuk from memory before moving on to harder problems.

Reference excerpt

Jan Poleszczuk (born 19 October 1986) is a Polish mathematician and biomedical engineer specializing in mathematical modeling in oncology. He is a researcher at the Nałęcz Institute of Biocybernetics and Biomedical Engineering of the Polish Academy of Sciences and a laureate of the Polityka Science Award (2017). His work concerns tumor growth dynamics, gene-expression modeling and optimization of radio- and chemotherapy.

Early life and education Poleszczuk was born in Poland on 19 October 1986. He received his Master of Science degree in mathematical methods in biology and social sciences from the University of Warsaw in 2010, defending a thesis on modeling tumor angiogenesis and anti-angiogenic therapy based on the Hahnfeldt model. Under the supervision of Maria Wideł and co-supervision of Urszula Alicja Foryś, he earned a Ph.D. in biocybernetics and biomedical engineering from the Silesian University of Technology in 2014 for the dissertation Mathematical modeling of cancer cell response to therapy-induced stress. He subsequently obtained a Ph.D. in mathematics from the University of Warsaw in 2015 with the thesis Exploring potential tumor growth modulating mechanisms in cells having different status of TP53 gene. In 2020 he was awarded the habilitation (D.Sc.) in biomedical engineering by the Nałęcz Institute of Biocybernetics and Biomedical Engineering, Polish Academy of Sciences, for his work Mathematical modeling in the study of evolution and treatment of cancer with radio and immunotherapy.

Academic career Since 2012 Poleszczuk has been affiliated with the Nałęcz Institute of Biocybernetics and Biomedical Engineering of the Polish Academy of Sciences, where he works on quantitative models of tumor response to therapy and radiobiological optimization. He has also collaborated with the Maria Skłodowska-Curie National Research Institute of Oncology on mathematical and computational methods in radiotherapy planning.

Research Poleszczuk has authored or co-authored more than 60 scientific articles indexed in MathSciNet, Zentralblatt MATH, and PubMed. His most cited works include Stochastic models of gene expression with delayed degradation (co-authored with Jacek Miȩkisz, Marek Bodnar and Urszula Foryś) published in Bulletin of Mathematical Biology (2011) and Mathematical modelling of immune reaction against gliomas: Sensitivity analysis and influence of delays (2013). His research integrates mathematical modeling, systems biology, and biomedical engineering to understand interactions between gene mutations and tumor growth and to improve therapeutic protocols in radiotherapy and chemotherapy.

Awards and membership Laureate of the POLITYKA Science Award (2017). Member of the Polish Mathematical Society (Treasurer 2017–2020). Member of the Polish Radiation Research Society, the Society for Mathematical Biology, and the American Association for Cancer Research.

Worked examples

Example 1 — a first encounter with Jan Poleszczuk

Start with the simplest possible case. Write down what Jan Poleszczuk claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jan Poleszczuk before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jan Poleszczuk ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jan Poleszczuk

In research: Jan Poleszczuk appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jan Poleszczuk in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jan Poleszczuk is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 births, 21st-century mathematicians, 21st-century statisticians, so understanding it makes those chapters shorter.
In everyday life: Look for Jan Poleszczuk outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
