That's an argument to authority, but there are many many more authorities that would disagree vehemently, and could back it up with specific statements. For example, Timothy Snyder, who is a historian specializing in the area, but really any sort of fair sampling would find that most Russian Studies professors would not be willing to uncritically repeat Kremlin propaganda like the "realist" school of international relations.
Plus, the idea that Russia had to invade a country to stop NATO expansion, if that's what's being asserted, is so farcical because countries want to join NATO to avoid getting invaded; it's a rather comical reversal. NATO expansion would stop really quickly if Russia would cease wanting to conquer neighboring countries; saying that Russia has legitimate security concerns just means that someone believes all these sovereign nations bordering Russia are not actually sovereign and should be part of Russia, which is again just repeating Russian imperialism as being right because it's right.
Plus, Putin has been pretty explicit in his writings on Ukraine, as he pretends to be a historian. Putin just wants to eliminate Ukraine as a nation and force Ukrainians to be subservient to Russians, it's all there out in the open in his writings. Denying this is kind of like trying to argue that Mein Kampf wasn't Hitler's real thoughts, and that Germany had to invade Poland and then the USSR simply for their own security concerns.
But if you can recall the name of this academic, it will be pretty quick to refute the specific claims made by other authorities in the area.
