In this episode of ML4Q&A, Chris and Mira talk with Alex Altland, theoretical physicist and ML4Q member, about the tension between deep scientific thinking and the administrative reality of coordinating the renewal proposal of ML4Q.

As one of the designated spokespersons for ML4Q’s next funding phase, Alex shares behind-the-scenes insights into managing this large-scale effort — just days before the final decision in May 2025.

We also explore his enduring fascination with foundational concepts in physics, spanning quantum field theory, quantum chaos, and topological matter. Alongside his research, Alex reflects on the importance of conceptual clarity in teaching, textbook writing, and his path from chemistry (and a brief detour into business consulting) to becoming a deeply theoretical physicist.
