), and studying many novel and subtle features of this class of models. Giorgi Dvali was invited to the 25th Solvay Conference in Brussels to participate in the discussion of "The Theory of the Quantum World". Dvali is actively engaged in teaching activities. During 1997–1998, he was a professor at ICTP. Currently, he is a professor of theoretical physics at New York University (Center for Cosmology and Particle Physics) and the Ludwig Maximilian University of Munich, as well as the director of the Max Planck Institute for Physics (Munich) and a scientist-collaborator at the CERN Center for Atomic Research in Geneva. He is also a distinguished professor of the Free University of Tbilisi.


Honours and awards

Dvali received New York City's Mayor's Award for Excellence in Science and Technology in 2000. Dvali is a recipient of the David and Lucile Packard Foundation's Packard Fellowship, the Alfred P. Sloan Foundation fellowship, and the Humboldt Professorship (2008).


In popular culture

Gia Dvali is a well-known and highly respected figure in the Georgian scientific community. In recent years, he has been a frequent speaker at universities throughout Georgia, where he has shared his expertise and insights with students and faculty. He is widely recognized for his contributions to the field of theoretical physics and has received significant attention and admiration from the media and the public.


Personal life

Dvali is married and is a parent to two children, one son, and one daughter.


Political views

Dvali has publicly expressed his opposition to the Georgian government's actions during the

. He has called on the public to take peaceful actions such as protests, to express their desire for Georgia's future to be aligned with Europe, and for the country to be considered as a candidate for EU membership. He has stated that Georgia's historical identity is rooted in Europe and that the country has always upheld Christian values, not only through physical means but also through the principles upheld by its thinkers.
