Omowunmi Sadik has discovered many things in life, perhaps none more important than the value of challenging traditional perspectives in order to find new solutions to old problems. She is an internationally recognized researcher, known for her advancements in basic and applied research in bioanalytical and environmental chemistry. Her research interests include chemical and biosensors,
electroanalysis, and the use of electrochemical and spectroscopic techniques for studying human exposure assessment, endocrine disrupters, and toxicity of naturally occurring chemical compounds.
Sadik joined the faculty at Binghamton University in 1996 after serving as a National Research Postdoctoral Fellow at the US-EPA National Exposure Research Laboratory in Las Vegas, Nevada. She has received numerous merit awards for her scholarship, including the Chancellor’s Award for Research in Science and Medicine in 2001 and the Chancellor’s Award for Premier Inventors in 2002. She was also a visiting research scientist at the Naval Research Laboratories in Washington, D.C.in 2001.
Currently, her groundbreaking research focuses on microelectrode biosensors that are able to detect even trace amounts of organic materials. By turning the traditional approach to sensor development on its ear, she has developed several iterations of what can best be described as an “electronic nose.” Myriad applications for this technology include drug detection (in the place of drug-sniffing dogs) and bomb detection. She is also exploring a patent strategy for another technology that would provide an improved approach for recycling metal ions from industrial and environmental wastes. Sadik's objective is to understand the time and spatial concentrations of these pollution analytes in response to chemical and physical stimuli.
Ascertaining these behaviors will likely contribute to the understanding of
the fate and transport of organochlorine compounds in the environment,
and thus help to reveal possible detoxification mechanisms.
