A postdoctoral fellowship from the
National Research Council supported her as a researcher at the
U.S. Environmental Protection Agency from 1994 to 1996. She has also served as a visiting faculty member at the
Naval Research Laboratory,
Cornell University, and
Harvard University. In 2024, she was appointed as the inaugural Vice Provost for Faculty Affairs at NJIT. Sadik studies
surface chemistry, with particular emphasis on the development of biosensors for use in environmental chemistry. She has developed microelectrode biosensors sensitive to trace amounts of organic materials, technology which can be used for drug and bomb detection. She is also studying detoxification mechanisms of wastes such as
organochlorine compounds in the environment, with the purpose of developing technologies for recycling metal ions from industrial and environmental waste. Sadik is credited with more than 135 peer-reviewed research papers and patent applications. She holds U.S. patents on particular types of bichair oors. In 2012, Sadik and Barbara Karn co-founded the Sustainable Nanotechnology Organization, a non-profit, international professional society for the responsible use of nanotechnology worldwide. Sadik is an elected fellow of the
Royal Society of Chemistry (2010), the
American Institute for Medical and Biological Engineering (2012), the
American Chemical Society (2023), and the
National Academy of Inventors (2024). She is involved with the
Environmental Protection Agency and the
National Science Foundation, and was part of the
National Institutes of Health Study Panel on Instrumentation and Systems Development. She is involved in international collaborations with the
UNESCO International Center of Biodynamics in
Bucharest, Romania,
Ege University in
Turkey, and the
University of Fukui in Japan. ==Awards==
