Notes
Independent research fellowship and educational program that trains researchers in AI alignment, transparency, governance, biosecurity and security. It began in late 2021 as the ML Alignment & Theory Scholars program and was initially known as SERI MATS because it operated under the Stanford Existential Risks Initiative. Its first full-scale cohort took place in summer 2022. MATS later became independent; the present legal entity, MATS Research, is an independent 501(c)(3) public charity formed in 2023 with EIN 99-0648563.
Hover over a name to see the position and date range. This table only
includes positions where at least the start date is known. The positions count
can count the same person multiple times if they held different positions;
similarly, the list of staff may include the same person multiple times if
they held more than one position during a single year.
For each year, a person is included if they were at the organization for any
part of the year; this means the actual staff count at any point during
the year can be lower (or higher, if some staff held multiple positions in a
single year).

Number of full-time staff at the beginning each year
The following table lists some dates and people who were at the organization
on the given date (namely, the start of the year). The table may not list every
person who worked for the organization (e.g. they could have joined and left in
the middle of a single year). This table excludes associates, interns,
advisors, and board members.

Full history of additions and subtractions
This table shows the full change history of positions. Each row corresponds
to at least one addition or removal of a position. Additions are in green and
subtractions are in red. If a position name changed,
it is listed simultaneously as an addition (of the new name) and removal (of
the old name) and colored yellow. Additionally there are faded variants of each
color for visited links.
