"I've been fascinated by Terran history and methodology since I was a boy."
– Kovich to Philippa Georgiou, 3189 ("Die Trying")

Doctor Kovich was a Human Federation official who lived in the 32nd century.

In 3189, he interrogated Philippa Georgiou upon her arrival at Federation Headquarters. He was knowledgeable about Terran history and raised the supposition that the Terran Empire was "based on the maxim 'because we feel like it'". He was also curious about Georgiou, particularly her reasons for travelling to the future, and attempted to learn about her from her own questions and curiosity. He allowed her to destroy his tricom badge in the process, but offered as little response to her questions as possible. He did volunteer the knowledge that the Terran Empire "fell centuries ago", however, and that no crossing between universes had been made "in over 500 years", causing Georgiou visible distress.

Dr. Hugh Culber consulted Kovich in trying to find a cure for the ailment that had inflicted Georgiou due to her being both displaced temporally and dimensionally. He then showed Culber a holographic depiction of Yor, a time soldier and the only other individual known to have crossed both time and dimensions. Kovich told Culber that there was no way to cure Georgiou, but Culber proved him wrong after consulting USS Discovery's computer which had merged with the Sphere data, leading them to a supposed answer on Dannus V.

During Osyraa's commandeering of Discovery, Kovich expressed his reservations to Charles Vance about possibly destroying Discovery to keep it out of Emerald Chain hands, as he saw Discovery's spore drive as the way to reunite the Federation. (DIS: "That Hope Is You, Part 2")

In 3190, Kovich began working with the newly-reopened Starfleet Academy as a consultant, and saw that despite being the best their worlds had to offer, the cadets had no experience working as a team, especially with people outside of their own species. Seeking a solution, he contacted Dr. Culber, asking for a Discovery crew member to lead a group of cadets in a team-building exercise, believing that the crew had something special to offer because they came from an era before the Burn. Culber recommended Lieutenant Sylvia Tilly, who had been looking for a challenge outside of her "comfort zone". Following the success of the exercise, Kovich offered Tilly a teaching position at the Academy, and she accepted. (DIS: "All Is Possible")

Kovich was played by David Cronenberg.
Kovich's name was revealed in promotional materials for Star Trek: Discovery, but was not confirmed in dialogue until DIS: "All Is Possible".
Though Kovich doesn't wear a Starfleet uniform, his tricom badge suggests a rank of commodore, according to concept art outlining the 32nd century rank system. (TRR: "Scavengers")
