APS Outstanding Referee: Ádám Gali

Ádám Gali, part-time professor of our Department of Atomic Physics, receives the APS Outstanding Referee honor from the American Physical Society. Ádám works as a scientific advisor at the Wigner Research Centre for Physics, and holds a part-time professor position at BME. 
 
Instituted in 2008, the Outstanding Referee program expresses appreciation for the essential work that anonymous peer reviewers do for APS's journals. Each year a small percentage of the 82,000 active referees are selected and honored as Outstanding Referees. Selection is based on the number, quality, and timeliness of referee reports as collected in APS' database over the last 30 years.
 
Congratulations, Ádám!
