During his time at ���ϲ�����, he has spent half-year sabbaticals at Xerox Palo Alto Research Center and at Innovalight, Inc., a startup company. From 2014-1017, he served concurrently as a program director at ARPA-E, an agency of the Department of Energy. There he initiated the SHIELD research program of a dozen research projects for development of inexpensive efficiency retrofits for legacy single pane windows. He also supervised a portfolio of additional projects on solar energy conversion and other energy technologies.

Schiff’s own research accomplishments include development of low-mobility solar cell device physics for thin film solar cells such as perovskites, amorphous silicon, and cadmium telluride. His fundamental physics contributions include work on electronic transport and defects in semiconductors as well as on plasmonics. He is co-author of more than 100 refereed research publications with more than 4,000 citations and he is co-inventor on three U.S. patents. He is a Fellow of the American Physical Society.

Research Interests

His research is focused on the structural and tectonic analysis of rift and transform plate boundaries. investigations of contental extensional terranes, rifted continental margins, Iceland and mid-ocean ridges provide overlapping perspectives on crustal accetion across a spectrum of environments dominated by magmatic construction and mechanical deformation. He uses outcrop-scale data collected from a wide range of research approaches including field geology, drone imaging, and seafloor investigations using submarines, ROV’s, and AUV’s to constrain larger-scale tectonic processes. The cross-pollination of data and processes from different environments helps to provide a more comprehensive understanding of crustal accretion on Earth and other planetary bodies.

Prof. Karson is also one of the leaders of the . The lave pours promote and allow for scientific experiments, artistic creations, education and outreach to the ���ϲ����� and City communities.

In addition to a series of graduate research assistantships at Johns Hopkins, she was a student investigator at the Centre for Child and Adolescent Health, Dhaka, Bangladesh and the National Institute for Diagnosis and Vaccine Development in Infectious Diseases, School of Public Health, Xiamen University, Xiamen, China where she Implemented a study examining the persistence of antibodies after hepatitis E virus infection.

Her professional portfolio includes participation on numerous research grants, including an award from the Bill and Melinda Gates Foundation where she was a student investigator on the project, “Determinants of Immunological Persistence of Hepatitis E Virus Antibodies.” The purpose of the study was to determine antibody persistence after Hepatitis e virus and vaccination in South Asia.

Dr. Preston directs the Speech Production Laboratory with the mission to develop, evaluate, and disseminate neurolinguistically-motivated and evidence-based assessments and treatments for speech sound disorders. Dr. Preston is also a faculty member of the .

More recently, Doherty has expanded her research to include studies of innovative signal processing strategies, which may increase the benefit individuals with hearing loss can derive from amplification. In addition, Doherty has been on the forefront of researchers demonstrating the increased mental effort for understanding speech that is required when individuals with hearing loss do not wear hearing aids.

Dr. Doherty is a Gerontology Faculty Affiliate since 2007 and is also a member of the  and the

He and his team investigate important interactions among these trophic levels, which, in turn, facilitate energy and nutrient flows in Yellowstone grasslands and foster stability of this ecosystem that experiences high chronic levels of grazing.

The Frank Lab utilizes field and laboratory experiments. In the field, he and his team erect ungulate enclosures to create an un-grazed treatment and then compare plant growth and soil processes in grazed versus un-grazed grasslands. In the lab, experiments are conducted in the greenhouse or environmental chambers to determine how mycorrhizae, nutrient availability, and soil microbial composition and diversity may mediate the effect of grazing on plant growth.

He also examine effects on wetlands, the Great Lakes, urban ecosystems, coastal waters and the open ocean. Over the past 35 years, he has advanced new analytical techniques, established and maintained long-term measurements and experiments, and developed a series of research and predictive models that simulate transformations of major chemical elements in forest vegetation, soil and surface waters in response to air pollution, climate and land disturbance. Beyond theory, he is interested in testing ‘in situ’ strategies to reverse the damaging effects of acid rain and mercury contamination and eutrophication. Current research includes using models, field experiments and measurements to examine: ecosystem effects of changing climate and acidic, nitrogen and mercury deposition; the effectiveness of “green” water infrastructure in storm water management; and ecosystem restoration.
