Leadership and pay
Who runs it, and what are they paid?
Officers, Directors & Key Employees
Tatiana Toro’s $331K as Director is at the 33rd percentile of top reported officer pay among 139 $10–100M science & technology nonprofits. Peer set: organizations in the same NTEE major field of work and revenue-size band, compared on each org’s own highest-paid officer/key-employee, from Form 990 Part VII / 990-PF Part VIII. Descriptive placement, not a verdict on whether the pay is appropriate.

Names, privacy, and removal requests More
The names, titles, and compensation shown on this page are reproduced from IRS Form 990 filings, which are public records.
Philanthropy.org does not alter the content of those filings. All information appears exactly as reported by the filing organization for the tax year shown.
We publish only information contained in the public IRS filing — and less than the filing contains. Our profile pages do not display street addresses, telephone numbers, personal email addresses, or other personal contact information, even where the filing includes them.
Many people share the same name. A name shown on this page reflects only what one organization reported in one IRS filing for one tax year. It should not be interpreted as identifying any other individual with the same or a similar name.
If you are no longer affiliated with the organization, your name will generally stop appearing in future IRS filings once the organization no longer reports you. Pages for tax years in which you were reported remain published because those filings remain part of the public record.
Philanthropy.org does not alter or remove IRS filing records. Removing a page from this website would not remove the underlying IRS filing, which remains publicly available from the IRS and other publishers of the same information.
If you believe the IRS filing itself is inaccurate, corrections must be made by the filing organization or the IRS directly.
