Our Leadership
In managing the organization's financial health, public reputation, and operations, Isaacs is supported by an executive team. Additionally, the Directors of Carnegie's three research divisions work with Isaacs to shape our scientific direction. Together, Carnegie Science's leadership suite ensures that we is able to maintain our independence, pursue advantageous partnerships, and advance scientific breakthroughs.

Experimental petrologist Michael Walter became Director of the recently formed Carnegie Earth & Planets Laboratory in 2022, where he was previously Deputy Director.

Mulchaey is a renowned astronomer, well-regarded for his work on groups and clusters of galaxies—most of which, including our own Milky Way, exist collectively.
