Biography
Silvana Andreescu is the Egon Matijević Endowed Chair in Chemistry and Professor of Bioanalytical Chemistry at Clarkson. She received a PhD in Chemistry, from the University of Perpignan, France, and the University of Bucharest, Romania in 2002, and has been a member of the Clarkson faculty since 2005. Between 2003 and 2005 she was a NSF-NATO postdoctoral fellow at the State University of New York at Binghamton. She is the recipient of a French Government Graduate Fellowship, a NATO-NSF Postdoctoral Fellowship, the NSF-CAREER Award, the John W. Graham Faculty Research Award, the Research Excellence Award and a Member of the Million Dollar Club at Clarkson University, reflecting funds received for sponsored research. In her research lab she has worked with and mentored over 15 graduate students, 4 post-doctoral fellows, 10 international visiting researchers, including a Fulbright Fellow, 3 high school teachers and over 50 undergraduates. She is committed to the success of her students and fellow researchers, many of whom are continuing their education at top graduate institutions or have secured rewarding positions in industry or academia.

Research Interests
- biomolecular recognition of nanoscale materials
- technologies for the immobilization of enzymes and biomolecular receptors
- single-molecule electrochemistry
- microelectrochemical probes for investigations of molecular mechanisms in biological systems
- portable nanoparticle-based assays for food analysis and environmental monitoring
- printable paper-based biosensors and field portable instrumentation
Current Research
Our research interests are in the areas of bioanalytical chemistry, electrochemistry, bionanotechnology, biosensing and environmental nanotechnology. We use modern spectroscopic and electrochemical instrumentation to study molecular level interactions of nanoscale materials, and we design devices that are inexpensive, easy-to-use and have the required detection sensitivity and selectivity for routine applications. Examples of our research projects include:
- field tests that change color within minutes when exposed to toxic chemicals, allowing testers to immediately detect the presence of harmful contaminants in food and environmental samples
- microelectrodes which allow us to study single molecules and measure physiological biomarkers
- electrochemical investigation of engineered nanoparticles and their interactions
New sensing technologies accessible to a broad range of users can substantially improve our measurement capabilities and generate scientific and technological advances for improving the quality of our environmental and, in essence, the quality of human life.
These projects provide students with the opportunity to learn methods for materials characterization, study biomolecular recognition, design their own devices and perform analytical characterization and measurements, all in an effort to address relevant scientific and engineering challenges. Research spans the traditional boundaries of chemistry, materials, biomolecular science and engineering disciplines.
