Embryology and seed set
We developed a custom fiber optic sensor system for small molecules sensing. These sensors were used in a USDA greenhouse study of soybean heat stress (Gainesville, FL). For more information on the applied work see research page of Dr. Bernard Hauser.
We have applied this multiplexing device in plant physiology (embryology) for studying the effects of climate on soybean seed set (Chaturvedi et al 2014)
We have used the multiplexing oxygen sensor for studying a coastal biogeochemical systems known as a microbialite. For more details on microbialites see the research page of Dr. Jamie Foster.
Diel cycling in marine microbialites at various depths (Chaturvedi et al., 2014; Chaturvedit et al., 2017)
Our group has developed low cost electrochemical sensors and handheld acquisition systems for detecting small molecules and bacteria important for food safety analysis. Sensors have been developed for targeting L. monocytogens, E. coli O157:H7, Salmonella, or biogenic amines in food products.

Plant stress signaling
We have applied a number of self referencing microsensors for monitoring stress response in plants. These-non invasive sensors have been used to monitor a wide range of targets (sugars, ions, hormones) in plant roots and leaves.
*A summary of the self referencing technique can be found here
Biosynthesis and accumulation of jasmonate (JA) regulates plant defense responses and organ development during insect herbivory. Our studies show that JA signaling also modulates root growth by reducing auxin transport in roots and altering stomatal conductance in leaf cells.
