Our Accomplishments

Dr. Panigrahi and his research group have contributed significantly in the area of sensors, sensing systems, computer-based intelligent systems as well as decision support systems including artificial intelligent techniques. His group is one of the early pioneer in developing such sensors and sensing systems from 1990s. 

 

In mid-1990’s, Dr. Panigrahi created new field-scale non-destructive sensors to determine the quality of selected agricultural products (protein content of wheat, sugar content of sugar beets) during harvesting. This work resulted in three approved (U.S.A.) patents for Dr. Panigrahi (as the lead inventor) and his colleagues. The developed methods can be modified for sensing other quality parameters. These patents, first of its kind, were more than 15 years ahead of its time. Today, the developed technologies are a part of the sought-after solutions for the digital agriculture revolution.

In early 1990’s, Dr. Panigrahi conceived the idea and worked with a plant pathologist to develop an artificial neural network (machine learning) model for predicting plant diseases in wheat.This work was an enabling technology for crop disease management and its impact was very high for the researchers and the growers. In precision farming domain, his contributions were also in: a) non-contact optical sensor development to predict nitrate and chlorophyll content of plant leaves and b) algorithm development to predict plant and soil nutrition using satellite images.  Moreover, a developed image recognition algorithm by his group is being used with modifications for agricultural land use applications in California. Dr. Panigrahi has successfully developed photonic sensing and electronic nose technologies for quality and safety of food products. For packaged meat, his group also developed multiple sensing methods including a portable electronic nose-based system for detection of spoilage and contamination.

This overall research has created positive impact in advancing engineering and sensor techniques for precision farming, agricultural production, food safety & quality applications. Many papers have been presented in conferences and published in referred journals including in the ASABE conferences and journals. He authored or co-authored two book chapters on imaging and sensing techniques for food products. Recently, he and his group have extended their expertise for environmental and health-care applications.
