I was born in Toruń, Poland on 29th of April 1955. My family tree has a long and rich history; it also includes several figures who could be familiar to Polish history and literature enthusiasts. My maternal great-great-grandfather, Count Aleksander Fredro, was a poet, playwright and author active during Polish Romanticism. Also, my great-grandfather, Piotr Szembek, was a military general in XIX century. My father’s family, on the other hand, immigrated in XIX century to Poland from Alsace, where Weyman is a pretty common surname. Both of my parents were doctors. I attended IV LO High School in Toruń and as far as I can remember, I was interested in mathematics since the 4th grade, inspired by the teacher we had that year. When I entered the Faculty of Mathematics at Nicolaus Copernicus University of Toruń in 1973, I got really passionate about algebra since the very first year, partly thanks to the courses taught by my math mentor, Tadeusz Józefiak.

In 1977 I successfully defended my master’s thesis, which focused on the Ideals Generated by Monomials. I took a position of Assistant Professor at the Mathematical Institute of the Polish Academy of Sciences. Shortly after, I was accepted to the graduate school at Brandeis University in Massachusetts, USA, where I had a pleasure to study with David Buchsbaum and David Eisenbud. I finished my PhD in 1980, focusing on Free Resolutions of Determinantal Ideals. The results of my thesis were published in joined papers with Kaan Akin and David Buchsbaum. In early 80s I came back to Poland to continue my previous position of Assistant Professor at the Mathematical Institute of the Polish Academy of Sciences. During that time, I was actively crafting my analytical skills by working on Commutative Algebra Problems together with Tadeusz Józefiak and Piotr Pragacz.

In 1985 I immigrated to the United States for good to take a position of Assistant Professor at the Northeastern University of Boston. In 1990 I was promoted to a degree of Associate Professor and I finally rose to the range of full professor in 1995. During my stay at Northeastern University I had an opportunity to cooperate and publish with many renowned mathematicians, including Harm Derksen, Kiyoshi Igusa, Marc Levine, Joseph Landsberg, Gordana Todorov and Andrei Zelevinsky.

In 2003 I published my first book entitled Cohomology of Vector Bundles and Syzygies by courtesy of the Cambridge University Press. Four years later, in 2007, I had a pleasure to teach in an INDAM Course in Algebra at the Tor Vergata University of Rome. In 2012 I was honored with Humboldt-Forschungspreis Research Award of the Alexander von Humboldt Foundation in recognition of my lifetime achievements, which resulted in several visits to the University of Duisburg-Essen in Germany.

In 2013 I moved from Massachusetts to Connecticut to take a position of Stuart and Joan Sidney Professor of Mathematics at the University of Connecticut. The same year in spring I contributed to the Commutative Algebra Special Year at MSRI (Mathematical Sciences Research Institute in Oakland, California) as the Simons Research Professor. Also in 2013, I obtained the title of Professor in Poland, my country of origin. In 2015 I was awarded Wacław Sierpiński Medal and Lecture, granted by the University of Warsaw and the Polish Mathematical Society. The subject of my lecture was Application of Algebra to Complexity Theory. In 2017 I published my second book (co-authored with Harm Derksen) called Introduction to Quiver Representations by courtesy of American Mathematical Society Publishing House.

In 2019, after spending 34 years of my life in the United States, I decided to move back to Poland and join Jagiellonian University in Cracow as the Professor of Mathematics. In 2021 I had a pleasure to claim the Stefan Banach Prize of the Polish Mathematical Society for outstanding achievements in mathematical sciences.

As of today I keep working at the Jagiellonian University where I lead several research projects.
