Research Scientist (Digital Agriculture)

Remote Sensing, Phenomics and Agro-Ecosystem Resilience. Mainly working on Proximal and UAV based RGB, Thermal, Multispectral and Hyperspectral Imaging applications in the framework of Precision Agriculture and Plant Phenotyping.

Current research and/or projects

  • Developing a robust digital imaging system for controlled and field-based environments phenotyping to support plant breeding program
  • Engaged in advanced sensors technologies, artificial intelligence (AI) and data-driven agriculture research to identify complex physiological traits
  • Optical sensing technology for development of stress resistance high yielding cultivars in a changing climate (plant phenomics)
  • High-throughput imaging capabilities for safe and effective uses of herbicides and fertilizers in field crops (precision agriculture)
  • Retrieval of bio-chemical and bio-physical parameters from leaf and canopy spectra to estimate plant photosynthesis capacity (imaging spectroscopy)
  • My research mainly integrates autonomous systems, AI models (machine/deep learning), and big-data analytics in digital agriculture to develop tools to promote growing crops in smarter and more sustainable way.

Research and/or project statements

Over last ten years, I gained expertise in high-throughput aerial imaging and digital agriculture to study horticulture, oilseed rape, legumes and cereal crop phenomics. I have developed an advanced calibration and imaging methodology to improve robustness of UAV-acquired remote sensing data to identify stress response by crops with high classification accuracy. As an Agrophysicist and UAV pilot my research area include Hyperspectral Imaging (HSI) technology for plants health detection, resistance to biotic (pest, disease, weeds) and abiotic (drought, heat, cold) stresses, and nutrient status. It involves agronomic data processing, association of GHG emission, image-cube analysis, AI algorithms development, crops mapping and predictive analytics. My research focuses on applying innovative sensing technologies to advance the data science into traditional agricultural industry to facilitate the digital Ag revolution for global food security.

International experience and/or work

Research Ass. (RA) at the Department of Plant Sciences, University of Saskatchewan, SK, Canada [2018–2020]

Worked on UAV-based multidisciplinary projects which mainly included canola, wheat, and lentil crops phenotyping. My research focused on different canola genotypes seedpods maturity and shattering problem; nitrogen use efficiency (NUE) in canola varieties; wheat cultivars phenotyping and yield prediction strategies using machine learning and statistical models; assessment of wheat stripe-rust in a nursery; evaluating different herbicides responses to dry down the lentils.

Post-doctoral Employee at the College of Agricultural and Environmental Sciences, University of California- Davis, CA, USA [2015–2017]

Worked on the greenhouse and UAV-based Hyperspectral Imaging technology in study of host selection by selected insects/pests and abilities to assess crop health via reflectance profiling in the framework of Precision Agriculture (detection of crop responses to biotic & abiotic stressors). Here, I have studied different horticultural crops and nut-fruit trees grows in the central valley, California. It included strawberry, soybean, tomato, gerbera, rice, almond and walnut orchard.
