Mellon Foundation

The Andrew W. Mellon Foundation was established in 1969 to strengthen, promote, and defend the arts and humanities as essential to democratic societies. Throughout our history, Mellon has held true to our founding commitments, secure in our conviction that the arts and humanities are essential to the health of a multivocal and democratic society. From our earliest days, we have aspired to build partnerships with our grantees, offering expertise and counsel in addition to funding

In recent years, Mellon has expanded on these core principles by actively prioritizing social justice across all of our grantmaking. This strategic shift builds on our long history of advocating for and investing in expanded access to higher education, humanities, and the arts, and addressing historical inequities in these fields. Our vision for Mellon’s future includes a focus on justice for all in all that we do—rooted in the Foundation’s long-held historic belief in the impact and power of the arts and humanities. At Mellon, we make grants to actively support communities and ideas that unlock the power in the arts and humanities that helps connect us all.

Humanities in Place Grant Program

The Andrew W. Mellon Foundation actively works with our grantee partners and we are deeply immersed in the fields in which we invest. Our grants are designed to activate the spirit of learning through the creation and sharing of bold new ideas and the inspiration felt in art, expression, spaces, and scholarship. 

From Alaska to Guam and the Borderlands to the Midwest, America is a constellation of unique heritages, traditions, and stories. In communities of all sizes, people are striving to expand the ways we can understand and authentically engage with the history that is all around us. Our Humanities in Place grants fund place keepers, artists, institutions, and storytellers who shine a spotlight on historically overlooked sites, and the communities and stories that surround them. In doing so, they help broaden our shared understanding and open new paths to discover what unites us, what makes us unique, and what we can learn from one another.

Mesothelioma Applied Research Foundation Inc

The Mesothelioma Applied Research Foundation is the only nonprofit charity organization dedicated to ending mesothelioma, and the suffering caused by this cancer, by:

• funding research to improve treatment options;
• providing treatment support and education for patients and their families;
• and advocating for federal funding of research.

The mission of the Mesothelioma Applied Research Foundation spans across four distinct areas: through research, education, support, and advocacy the Foundation seeks to eradicate the vicious effects of mesothelioma. Led by the Board of Directors, our team works collaboratively to develop and administer our programs, and to fundraise to pay for those programs (the Foundation is funded by private individual and corporate contributions only — it does not receive any government funding).

Patient Travel Grant Program

A mesothelioma diagnosis and treatment often require the patient and their family to incur numerous expenses as part of their treatment. Travel to treatment, alone, can cause a significant financial burden on the patient, which might even cause the patient to not seek treatment away from home, even it’s their best option. To ensure that all patients have the ability to seek specialized help and treatments, the Mesothelioma Applied Research Foundation administers its Travel Grant Program.

The Meso Foundation’s Patient Travel Grant Program, founded by Mary and Bob Cosentino, provides travel grants to patients and one caregiver traveling for an initial consult and/or for clinical trial treatments.

• The type of eligible travel must fall into at least one of these two categories:
  • One trip for one initial consultation with a mesothelioma specialist.
  • Multiple trips to participate in an interventional clinical trial (found on clinicaltrials.gov).

Rosenthal Patient Assistance Fund grant program. This program is made possible by the generosity of the Rosenthal family.

Utilizing the Full Power of Empire AI Request for Applications

The Simons Foundation (SF) intends to support cutting-edge mathematics and basic science research, drawing on the advanced computational power of the Empire AI.

Toward this goal, SF plans to initiate a new program to fund six to 12 proposals through a competitive open call to the Empire AI research community.

A successful proposal will outline an ambitious two-year research program in one of the following fields, or at their intersections: computational astrophysics and physics, computational biology, mathematics, neuroscience and computational physical chemistry. Each proposal will necessarily rely on the development and utilization of foundational machine learning models, aimed at solving problems of fundamental importance in the above-listed disciplines.

Computational biophysics, neuroscience, ecology and evolution, plant biology, optimal transport, multiscale physics, fluid dynamics and numerical general relativity are representative examples of fields that could use multinode clusters of GPUs of Empire AI, which is a requirement of the program. All submitted proposals should detail how their work will use multinode clusters of GPUs in Empire AI. Proposals focused on data curation and creation of datasets can be considered in exceptional cases, as long as the attained data will be used by the proposers for solving scientific problems as part of the same proposal.

The program’s total budget is expected to be $6 million USD over a two-year period.

Funding

Award Amount: There is no maximum budget total for an individual award. The total amount requested should reflect the proposed research. All award amounts are inclusive of indirect costs (see our grant policies). Please note that we anticipate funding six to 12 applications. The total program’s budget of $6 million USD over two years will be spread across all awards.

Award Duration: June 1, 2027, through May 31, 2029.

Number of Awards: We expect to select six to 12 applications for funding.

Seeding Research, Networking, and Capacity Building at Minority-Serving Institutions

Introduction & Purpose

RWJF is committed to ensuring everyone has a fair and just opportunity to be as healthy as possible. To achieve this goal, we support research that examines the historical and systemic factors that cause health inequities. Some of those determinants are poverty, discrimination, and limited access to quality education, housing, safe environments, and healthcare. As attacks on data and academic freedom and ongoing funding cuts to federal health equity research and programs continue, philanthropy’s work to achieve fair and equitable health, including a more equitable research funding ecosystem, is more important than ever. While philanthropic support for Minority-Serving Institutions (MSIs) has increased in recent years, there is more to be done to rectify historical disparities in funding. 

This call for proposals (CFP) provides support to health equity research centers at MSIs to strengthen research infrastructure and capacity-building. Capacity-building will help develop staff, skills, culture, resources, and systems that enable research to happen effectively. Specific work that RWJF may fund under this CFP includes specific skill or methodology training; faculty release time; support for research assistants, advisors, and project staffing; mentoring, professional development and collaboration, and more.

Through this CFP, RWJF will expand its efforts to transform deeply rooted beliefs about which data and research methods are valued, whose perspectives are prioritized, and which populations deserve resources. By supporting the infrastructure and capacity-building needs of MSIs, this opportunity strengthens their ability to generate critical evidence and to cultivate transformative, actionable solutions toward health equity. 

RWJF believes in health equity research that is grounded in systems thinking; supports and disseminates evidence identifying and implementing structural solutions to racial and health inequities. This CFP seeks mission-aligned institutions to participate in cohort-style peer learning to advance their ability to engage in health equity research and apply for competitive funding opportunities in the future.

Although no single philanthropy can fill the gap left by federal funding cuts, this CFP demonstrates strong support for research, historically underrepresented researchers, and research centers that are positioned to pave the way toward a future where health is not a privilege, but a right.

The Cooperative Endangered Species Conservation Fund: Recovery Land Acquisition Grant Program, initiated in FY 2001, aims to foster collaboration between State and Federal entities in conserving listed species.
