Design and synthesis of the new immuno-suppressory substances
The immune system plays a key role in the life of vertebrates, protecting them against microorganisms. This very system however, can also cause transplants to be recognised as foreign bodies and to be rejected. The rejection may be delayed by administering immunosuppressive drugs that suppress the response to unfamiliar molecules. Although a number of immuno-suppressory substances are known, there are still no completely reliable drugs. Research of new, improved drugs is therefore necessary. In my project I've designed the structure and synthesised two peptides, which I assumed to be strong immuno-suppressory substances. The design of the structures was based on clear theoretical considerations. Biological research has confirmed the high biological activity of the peptides. I have also established that one of these might be successfully used in transplantology .

New finds of dinosaur tracks in the Holy Cross Mountains
I wanted to do research on dinosaur paleoichnology, which I think is very interesting, and I am not the only one, as in recent years a worldwide explosion of interest in dinosaurs has been observed. It followed scientific discoveries that have changed our understanding of the dinosaurs' biology. An important part of this revolutionary research concerns the fossilised dinosaur footprints. During fieldwork that took place between 1996-99 in the Holy Cross Mts., I made an interesting collection of dinosaur tracks. On the basis of modern measuring methods, I was able to identify some of the ichno species. Footprints were discovered of an early ornithischian dinosaur, predatory dinosaur tracks and sauropod's tracks. In this project my own data and ideas on the evolution of the early ornithischian dinosaur species have been presented .

Divisions of a convex polygon into parallelograms
I am interested in when a convex polygon is divisible into a finite number of parallelograms. I have proved that this occurs only when the polygon is centrally symmetric. Subsequently, I investigated the relation between those divisions and curves, called threads. I found that the number of divisions depends only on the number of the edges of the polygon, not on its shape. I have provided an algorithm to compute these numbers. The number of minimal divisions turns out to be staggeringly big, e.g. for a twenty-sided polygon there are about 2e10 different minimal divisions. I have provided a lower and upper estimate for those numbers. Finally, I studied the rotations of the division, and identified some algebraic properties .
