Mississippi State University

I am an Assistant Professor in the Department of Agricultural and Biological Engineering at Mississippi State University. My research resolves around the development and deployment of non-destructive sensing (e.g., optical imaging and spectroscopy) and automation technology for addressing the pressing problems in the agricultural and food domain. After earning my doctorate, I worked for over 1 year for USDA-ARS at East Lansing, Michigan, on optical imaging for qualty evaluation of horticultural products, and apple harvest-assist and in-field sorting technology development, and later spent another year in the Department of Biological and Agricultural Engineering at North Carolina State University on several projects on imaging-based high-throughput plant phenotyping and precision agriculture.

Projects

Advancing Optical Technologies for Enhanced Quality Evaluation, Grading and Sorting of Sweetpotatoes (2022-2025, USDA-AMS, Specialty Crop Multi-State Program)

This multi-state project aims to advance non-destructive optical technologies for enhanced quality evaluation, grading and sorting of sweetpotatoes. Specifically, this project will: develop computer algorithms for quantification and classification of appearance quality of sweetpotatoes using machine vision technology; evaluate hyperspectral and interactance imaging for detecting internal quality, including firmness, soluble solids, dry matter, and internal defects of sweetpotatoes; develop and evaluate an automated sweetpotato grading and sorting machine prototype.

Develop image databases to support machine vision-based cotton weed control and harvest and deploy deep learning models for weed detection towards precision weeding (Cotton Inc., Cary, NC)

This proposed project aims to develop and deploy deep learning models for weed detection for cotton production systems. We will pursue three sub-objectives: 1) Collect and label new images of weed species in cotton fields across Mississippi and integrate images supporting robotic cotton harvest systems (mature bolls); 2) Develop and evaluate deep learning models for weed detection; 3) Deploy deep learning models on a machine vision prototype for in-field weed detection.

Sinusoidal-Illumination Imaging (SII) A Potential Tool for Enhanced Detection of Muscle Defects and Microbial Spoilage of Poultry (2022-2023, USDA-NIFA)

The prevalence of muscle defects in broiler meat, such as white striping, woody breast and spaghetti meat, is threating the profitability and sustainability of the U.S. poultry industry. Poultry products are also highly susceptible to microbial spoilage or contamination, leading to substantial product and economic loss and potential food safety issues.

Nondestructive Detection of Spotted Wing Drosophila Infestation in Blueberry Fruit Using Optical Imaging (2021-2023, USDA-AMS Specialty Crop Block Grant Program)

Spotted Wing Drosophila (SWD) is a devasting pest for blueberries grown in Mississippi and beyond. Blueberry growers are under intense pressure to monitor SWD infestation and protect yield loss. The zero tolerance for SWD larvae inside the fruit is also posing significant challenges for packinghouses in identifying and removing infested fruit to ensure safe fruit to consumers.

Utilize Machine Vision Technology to Improve Efficiency and Reduce Labor of Local Sweetpotato Packing Lines (2021-2023, USDA-AMS Specialty Crop Block Grant Program)

In this project, we will ollaborate with local sweetpotato packinghouses to enhance the efficiency and reduce human labor of packing operations by: 1) assessing the status of automation technology utilized in local sweetpotato packing lines and 2) designing and evaluating a machine vision technology-based inspection system for automatically grading and sorting sweetpotatoes for size, shape and defects.

Cotton Weed Database Development and Deep Learning Model Benchmarking (Cotton Inc., Cary, NC)

This research is to develop a large-scale, public image database of cotton weeds in the field and benchmark deep learning models for weed detection, with the ultimate goal to enhance computer vision-based robotic weeding for cotton.
