About the Program


The Hoffman Program encourages Pilot Grants to promote scientific understanding and public awareness of chemical exposures, with a focus on multiple chemical sensitivities (MCS), also known as toxicant-induced loss of tolerance (TILT) or DELTA.

The Pilot Grant Program aims to:

  • Stimulate research on MCS/TILT/DELTA
  • Advance understanding of health consequences of chemicals and other toxins in the environment
  • Identify and promote actions to protect vulnerable populations

Ordinarily, grants of up to $25,000 are offered once a year. Funds are typically used for feasibility studies and to produce preliminary data to compete for independent funding.

Requests for Pilot Grant applications will be announced periodically via postings at the Harvard T.H. Chan School of Public Health, by email, and on our website. Due date for submission is usually 40-50 days after the announcement.


All faculty at the Harvard T.H. Chan School of Public Health are eligible to apply for Hoffman Pilot Grant funds. Applications are accepted also from Harvard Research Associates or Fellows working under the supervision of Harvard Chan School faculty, but the role of the sponsoring faculty member must be specified. Doctoral students are NOT eligible for Pilot Grant support, but will be supported through intern opportunities.
