My photos (click here) of geometric and topological 3D models, printed by Nicholas Owad at OIST, designed by Nicholas Owad or Henry Segerman, some with the help of Seifertview. You are welcome to stop by my office to see them, and learn more about them. I enjoy capturing strange and beautiful shapes on camera even when I am not doing math. Here are some of the photos I took while scuba diving.

If you are interested in donating to Ukrainian volunteer groups, here I keep a short list of those I trust and try to donate to. When my parents and other relatives in Northern Ukraine were under Russian occupation in 2022, local volunteers were the only ones who delivered life-saving medical supplies and food, and arranged evacuations of civilians.
