Simons Investigators

Contact Info

Each year, the Simons Foundation requests nominations from a targeted list of institutions in the United States, Canada, the United Kingdom and Ireland for the Simons Investigator programs. Simons Investigators are outstanding theoretical scientists who receive a stable base of research support from the foundation, enabling them to undertake the long-term study of fundamental questions.

Only nominations from institutions that receive the request will be accepted. The Math+X and MMLS programs have been discontinued and the foundation will not be requesting future nominations. Please contact for more information.

Simons Investigators in Mathematics, Physics, Astrophysics and Computer Science

The intent of the Simons Investigators in Mathematics, Physics, Astrophysics and Computer Science programs is to support outstanding theoretical scientists in their most productive years, when they are establishing creative new research directions, providing leadership to the field and effectively mentoring junior scientists. Starting in 2020, up to two Simons Investigator in Physics awards will be granted to well-established researchers who develop and apply advance theoretical physics ideas and methods in the life sciences.

A Simons Investigator is appointed for an initial period of five years. Renewal for an additional five years is contingent upon the evaluation of scientific impact of the Investigator. An Investigator receives research support of $100,000 per year. An additional $10,000 per year is provided to the Investigator’s department. The Investigator’s institution receives an additional 20 percent in indirect costs.

To be an Investigator, a scientist must be engaged in theoretical research in mathematics, physics, astrophysics or computer science and must not previously have been a Simons Investigator. He/she must have a primary appointment as a tenured faculty member at an educational institution in the United States, Canada, the United Kingdom or Ireland, on a campus within these countries and the primary department affiliation must have a Ph.D. program.

Simons Investigators in Mathematical Modeling of Living Systems (MMLS)

This program aims to help the research careers of outstanding scientists working on mathematical and theoretical approaches to topics in the life sciences. A Simons Investigator in MMLS is appointed for five years.

Math+X Investigators

This program encourages novel collaborations between mathematics and other fields in science or engineering by providing funds to professors to establish programs at the interface between mathematics and other fields of science or engineering. A Math+X Investigator is appointed for an initial period of five years. Renewal for an additional five years is contingent upon the evaluation of scientific impact of the Investigator.

Jonathan Fortney, Ph.D.

University of California, Santa Cruz
Astrophysics | 2021

Jonathan Fortney models many aspects of the physics of planets, from rocky worlds to gas giants. His work in planetary theory focuses both on exoplanets that orbit distant stars as well as planets in the solar system. His models have provided a framework to understand the atmospheres of exoplanets, their interior structure and thermal evolution, as well as physical processes like helium “rain” deep within Saturn. Fortney often works closely with observers to interpret spectra of exoplanets to better understand their physics, chemistry and clues to their formation.

Yuri Levin, Ph.D.

Columbia University
Astrophysics | 2021

Yuri Levin works on astrophysics of neutron stars, black holes and gravitational waves. He is known for computations of thermal and quantum noise in LIGO interferometers, for co-discovering a disc of massive stars orbiting the supermassive black hole at the center of the Milky Way, for developing gravitational-wave search algorithms for pulsar timing arrays, and for his work on the dynamics of magnetized neutron stars. Levin is currently attempting to understand the architecture of stellar clusters near supermassive black holes and figure out the origin of pulsar glitches.

Brian Metzger, Ph.D.

Columbia University
Astrophysics | 2020

Brian Metzger is a theoretical astrophysicist whose main interests lie in the births and deaths of compact objects. His work on neutron star mergers played an important role in interpreting the electromagnetic signal which accompanied the first merger detected via gravitational waves. As a result of this discovery, these rare events are believed to be among the main sources of the heaviest elements in the Universe. Metzger also works on supernovae, gamma-ray bursts, thermonuclear explosions on white dwarfs and the destruction of stars by massive black holes. He collaborates with astronomers to interpret these events using data across the electromagnetic spectrum.

Karin Öberg, Ph.D.

Harvard University
Astrophysics | 2020

Karin Öberg studies the role of chemistry during planet formation. She combines theory, astronomical observations and experiments to explore the chemical environments within which planets assemble, the links between chemistry and dynamics in planet-forming disks and how the compositions of mature planets depends on the disk environment where they formed. Her models of planet compositions have provided an interpretive framework for the exoplanet community. Öberg’s work on the volatile and organic content of disks has begun to constrain how often we may expect to find planets with similar chemical starting conditions as those in our solar system.

Daniel Kasen, Ph.D.

University of California, Berkeley
Astrophysics | 2019

Daniel Kasen studies energetic astrophysical phenomena such as supernovae and compact object mergers and their applicability as probes of physics and cosmology. His models of electromagnetic signals have guided observational efforts and played an important role in interpreting the first neutron star merger jointly detected in light and gravitational waves. His work has helped illuminate the diverse ways in which stars die and how the heavy elements in the universe formed from their ashes.

Rachel Mandelbaum, Ph.D.

Carnegie Mellon University
Astrophysics | 2019

Rachel Mandelbaum is an observational cosmologist who uses data from large sky surveys to measure gravitational lensing (the deflection of light from distant objects by more nearby mass). She works at all stages of the measurement process, including data analysis methodology, production of theoretical predictions and development of statistical methodology. She uses gravitational lensing measurements to reveal the connection between the visible components of galaxies and invisible dark matter, which can answer basic questions about galaxy evolution and to reveal how cosmic structure has grown and evolved, which relates to the accelerated expansion rate of the universe and dark energy.


Yanbei Chen, Ph.D.

California Institute of Technology
Astrophysics | 2018

Yanbei Chen made major contributions to understanding the noise of laser-interferometer gravitational-wave detectors that arise from quantum fluctuations of light and matter. He proposed conceptual interferometer designs that can achieve better sensitivity — also formulating a vision for experimentally testing quantum mechanics and quantum measurement theory on macroscopic objects. Chen made important contributions to gravitational-wave data-analysis strategies and works on using gravitational-wave observations to test the predictions of general relativity in strong gravity and to study the structures of black holes.

Ue-Li Pen, Ph.D.

University of Toronto
Astrophysics | 2018

Ue-Li Pen is known for developing innovative tools to create new fields of research. His pioneering work on 21 cm intensity mapping opens a new window for the precision study of dark energy and neutrinos. Recently, his use of natural plasma in our galaxy as a giant telescope spawned the field of scintillometry, enabling new glimpses into enigmatic pulsars and the unsolved fast radio bursts. The orders of magnitude improved precision may improve our understanding of space-time, including gravitational waves.
