Personality
An outgoing, imposing but very kind man, Dr. Leskinen is both a respected scientist and a childish man, showing an optimistic behavior and a fondness for jokes.

However, as an agent of Strategic Focus, he secretly works seeking information on time travel and testing Amadeus' potential as military weaponry.

When it comes to acting as a scientist, Leskinen is ruthless, having no hesitation against human experimentation, and even resorting to torture and brainwashing to get the information he needs. He lives for his curiosity as a scientist and is not even afraid of breaking the world with time paradoxes. As Rintaro Okabe describes him, he is a true "mad scientist", a title Leskinen laughed at and took as a compliment.

Background
Leskinen is the mentor of Maho and Kurisu at the Viktor Chondria University in the United States of America. He is also secretly an agent of Strategic Focus.

Beta Worldline
In 1999, as a result of her programming, Kagari tracks down Leskinen. While he is initially confused, she explains future events and his roles in them to him. He then takes her to a Stratfo facility where she is experimented on for a number of years. He then goes on to take the steps necessary to eventually get his hands on the time machine, including creating Amadeus.

Possible Futures
In most Beta worldlines, Leskinen is involved in the capture and torturing of Okabe in the future. He is also the one who brainwashes a young Kagari, doing so under the guise of PTSD treatment.

Plot
In Steins;Gate 0 in the β (Beta) timeline, he brings Maho to Japan to assist him in his lectures about the Amadeus system. He speaks English in his lectures while Maho interprets it to Japanese, although he is shown to be able to converse in Japanese using a translator device. After the lecture, Leskinen notices Maho speaking to Okabe and introduces himself to the man. Upon learning of Okabe's relation to Kurisu, he decides that he is a suitable test subject for Amadeus.

Leskinen appears regularly as a side character throughout the game. Near the climax of the game, his true loyalties and intentions are revealed as he tells Okabe that that he intentionally set the situation up to get his hands on the time machine.
