Sam's research focuses on the design and fabrication of biosensors for the detection of pathogenic organisms, allergens, adulterants and other analytes of interest. Sam's research group is currently designing inexpensive sensors which will permit rapid on-site screening for food pathogens and toxins. Much of his groups work focuses on the development of nanoparticles and microfluidics for various food safety applications. http://www.umass.edu/biosensors
