A Journey in Lattice Field Theory with Wolfgang Bietenholz

Join us as we explore the fascinating journey of Wolfgang Bietenholz, a distinguished theoretical physicist known for his contributions to lattice field theory, cosmic rays, and other subjects. 


From his childhood in Basel, Switzerland, where his love for geometry began, through his rigorous academic path at ETH Zürich, Bietenholz’s story is one of remarkable achievement. His career highlights include his Ph.D. on chiral perturbation theory at the University of Bern,  a visiting position at CBPF in Rio de Janeiro, postdoctoral research at MIT, and significant roles at Forschungszentrum Jülich and NORDITA Copenhagen. At Humboldt University Berlin, he made significant advancements in the study of lattice Dirac operators and cosmic rays.

Currently, at Universidad Nacional Autónoma de México, he continues to build collaborations and mentor the next generation of physicists.


Bietenholz’s achievements are extensive. He has authored 170 scientific articles, accumulating over 3,600 citations. His work spans lattice field theory, quantum chromodynamics, and a variety of other topics, reflecting his versatility and broad interests in theoretical physics. He has served as a referee for 35 journals and 11 funding agencies, and supervised numerous theses, including 5 Ph.D., 9 M.Sc., 11 B.Sc., and 30 internships. 

Engaged globally, Bietenholz has participated in conferences and seminars in 30 countries, fostering scientific collaboration and contributing to popular science discussions, making complex concepts accessible.
