Research overview:
My research focuses on inverse problems for partial differential equations, particularly inverse scattering problems, or ISPs. ISPs aim to determine information about an object from measurements of its scattered field and are central to inverse scattering theory, an active area of mathematical research for the past four decades. These problems have broad applications in radar, nondestructive testing, geophysical exploration and medical imaging. My collaborators and I work to develop rigorous mathematical and computational methods for solving ISPs, advancing both theoretical understanding and practical applications in these fields.

| | Halo Can Help Faculty Find Industry Partners | | |
Halo is an artificial intelligence-powered technology platform that helps corporate research and development (R&D) teams more efficiently connect with scientific partners and bring innovations to market faster. On the first of each month Halo announces on its marketplace new research that is sought by its industry partners. These announcements are included in the Funding Connection each month. Typical awards are $50k to $175k with potential for follow on funding. Each funding opportunity (i.e. partnering request) on Halo accepts a single, standardized proposal that requires the minimum amount of information for an industry partner to determine the next steps. This is intended to save innovators/faculty time. The entire proposal is the equivalent of a page and takes most faculty less than an hour to complete. There is no contractual obligation and a more detailed proposal may be requested should a researcher be selected as a finalist.
Halo is not involved in the review process and every proposal is sent directly to the industry partner. Once a faculty member submits a proposal, they will receive an email from Halo's system letting them know what the estimated response timeline is from the industry partner. Typical response time is 2 months or less. The industry partner will either advance or decline the proposal as an initial response. The innovator will learn if their proposal is relevant to the request and the industry partner’s current business needs. The innovator can then expect a detailed response within 3 months from receiving their initial response. In the detailed response, the industry partner will either select the proposal for the finalist evaluation or decline it with feedback. If the innovator is selected as a finalist, they have reached the end of the review process on Halo. This means that the industry partner is interested in taking the conversation off of Halo’s platform and further evaluating the proposal alongside other finalists.
Since launching in 2020, nearly 8,000 academic scientists, 2,000 startups and 1,500 university administrators across 100 countries have created profiles on Halo describing their research interests. Of the more than 2,300 universities represented on the platform, more than 450 universities are U.S. based. Industry Partners include such companies as Cargill, Mars, Corteva, General Mills, Bayer, Under Armor, Eli Lily, UPL, PepsiCo, Unilever, Tata Steel, Proctor & Gamble and many more. The National Science Foundation is currently partnering with HALO in a $1.2 million effort designed to create new, diverse partnerships among emerging research institutions in U.S. higher education and industry innovators.
Some Halo opportunities announced in April include:
