Research page is accessible from the Map View. Its icon is aligned above the Nearby tab in the bottom right corner of the screen.
Research page is divided into three tabs:
- Field tab which includes Field Research tasks and Research Breakthrough stamp progress,
- Special tab which includes ongoing Special Research campaigns and list of completed ones
- and Today View tab which includes Timed Research campaigns, bonuses for current events, daily PokéCoins and Daily Bonuses progress.
Initially, the Research Breakthrough stamp progress section was present at the top of the Research page and the tabs with Field and Special research were below it, thus the Breakthrough progress was displayed regardless of which kind of research tasks were viewed at the moment. It was misguiding and got changed with later updates — Breakthrough section was moved to the Field tab.
Research tasks and rewards
There are plenty kinds of Research tasks that work slightly different.
Field Research are tasks that can be gathered by spinning Photo Discs of PokéStops (Gyms do not give tasks). Each PokéStop can only give one task per day. Each PokéStop changes the tasks at 00:00 AM local time per day. Once the Trainer has completed that PokéStop's task for the day, a small icon is displayed in the top right corner of the PokéStop's Photo Disc view.
Field Research tasks have objectives that include catching certain Pokémon, performing basic actions in the game or battling in Gyms or Raid Battles. These tasks are directed as more casual so players can complete them in 15 to 30 minutes. 
While Special Research tasks have specific rewards for each task and each set of tasks, for Field Research there seems to be variety of different rewards for each task completed. The more difficult the task, the greater the reward. Trainer can have up to three Field Research tasks at a time, but they can be also cancelled at any time, so other tasks can be gathered (trainer can obtain the deleted one from the same PokéStop during the same day). There is no limit to the number of research tasks that can be completed each day.  It is possible to obtain multiples of the same task from different PokéStops during the same day; in this case, a single action will count towards progress for both of them.
Beginning in 2019, there has been a Limited Research event. During the event, PokéStops will assign tasks to Trainers and reward them with a featured Pokémon. The Pokémon that is rewarded will have a chance to be shiny.
- For the full list of Field Research tasks, see: List of Field Research tasks and rewards.
Daily, the Trainer receives a bonus Field Research task automatically. The tab is made light green in color to be recognized. A fourth slot will be opened for the bonus task if the three Field Research tabs are filled. However, if all four Field Research slots are filled, Trainer won't receive the bonus task.
This feature was introduced on April 30th, 2020. The research was the same for all Trainers on the first day, but then it can vary.
Special Research are campaigns split into parts with sets of unique tasks requested by Professor Willow himself. Each Special Research task can be completed only once per player and for each set of Special Research tasks there are unique special rewards. 
- For the full list of Special Research campaigns, see: List of Special Research tasks.
Since May 2020, there is an additional kind of Research campaigns called Timed Research that works very similar to Special Research campaigns however its accessibility is limited for a specific period of time after which Timed Research is gone and no longer accessible regardless of the Trainer's progress on it. Unlike Special Research campaigns these kind of Research sets can be viewed in Today View tab instead of Special Research tab.
- For the full list of Timed Research campaigns, see: List of Timed Research tasks.
Daily Research is a feature that allows Trainer to obtain few more PokéCoins for completing whole set of Daily Research tasks. It is currently tested in several countries, including: Australia, Germany, New Zealand and Taiwan.
Following tasks were reported to appear in Daily Research:
- Catch a Pokémon.
- Transfer a Pokémon.
- Evolve a Pokémon.
- Power up a Pokémon.
- Use a Berry to help catch a Pokémon.
- Make a Nice Throw.
- Make a Great Throw.

Stamps and Research Breakthrough
- Main article: List of Research Breakthrough rewards
Trainers can earn one Stamp per-day by claiming the reward from a Field Research task. Once seven stamps have been obtained, a Research Breakthrough can be achieved. 
The stamp is earned upon claiming the task's reward, not when the task is completed, so if you complete two tasks in a day, you can opt to save one to get another stamp for tomorrow by not claiming one of them. For Pokémon appearance rewards, tapping claim reward will give you the stamp, not when you actually catch them.
It is currently unknown what is the purpose of Special Research stamps that are present in the game files, as only Field Research stamps can be currently obtained by players.
