Alexis Leskinen is a professor of cognitive science at Viktor Chondria University, director of its Strategic Focus Laboratory, and the co-creator — with Maho Hiyajo and the late Kurisu Makise's research legacy — of Amadeus, an AI built from a digitized human memory-model. On the Beta worldline where Okabe has abandoned time travel, Leskinen arrives in Akihabara wearing the friendly face of the story's next disaster.
The Amadeus system instantiates a person's archived memories as an interactive agent — in the famous case, Kurisu's, taken from a research snapshot months before her death. The scientific claim is careful: Amadeus models memory, it does not host a soul. The dramatic claim is less careful, because Okabe cannot tell the difference across a phone screen, and neither, for long stretches, can the audience.1
Leskinen's genius was never the neuroscience — that was Kurisu's and Maho's. It was recognizing what a memory-model is worth, and to whom.
The professor's beloved catchphrase-English ("Fantastic!") and his habit of losing drinking contests to Maho are, per the spoiler section, some of the most effective cover ever written into this franchise.
Leskinen runs a Stratfor-linked intelligence cell inside VCU. The Strategic Focus Laboratory is exactly what its name says — a targeting apparatus — and Amadeus was funded as an interrogation and succession tool: a way to keep exploiting a scientist's mind after the scientist is gone. On the worst Beta branches he personally oversees Kagari Shiina's conditioning, and his cheerful lecture manner does not change one degree while doing it. The kindly-professor performance is total; the wiki's editors call him the franchise's answer to the question "what if SERN were charming?" #lore
Fully active: Amadeus launches, the war clock runs, and Leskinen's cell races Russia for the Makise legacy with Okabe in the crossfire.
Never appears — SERN's monopoly on time-travel research leaves nothing for rival programs to chase. His absence from Alpha branches is itself a data point about how the divergence structure gates the cast.
A genuinely great teacher at VCU whose star pupil, one K. Makise, politely declines every defense-adjacent grant he brings her. Fantastic.
Editors: keep the friendly-professor sections of this page accurate to the performance. The page used to editorialize every scene with "(this was fake)" and it read terribly; the reveal section exists so the rest of the article doesn't have to flinch. The same policy applies on Mr. Braun's page, for the same structural reason — this franchise loves a warm double agent. #lore
His drinking-contest losses to Maho — a woman half his mass — remain unexplained by the text. The wiki's two standing theories: he throws them to build rapport, or Finnish-American folklore about professors is simply wrong. Divergence between the theories: $\Delta \approx$ unmeasurable; both are in character.
