Assistant Professor

Michigan State University

I am an Assistant Professor in the Department of Biosystems and Agricultural Engineering at Michigan State University (MSU). Before starting the position in January of 2023, I was a Postdoc scholar with USDA-ARS on the campus of MSU for 2018-2019, focusing on optical imaging for quality evaluation of horticultural products and machine vision-based apple in-field sorting technology development (click here). Thereafter, I joined the Department of Biological and Agricultural Engineering at North Carolina State University, with research on imaging-based high-throughput plant phenotyping and precision agriculture. I was an Assistant Professor in the Department of Agricultural and Biological Engineering at Mississippi State University for 2020-2022.

Welcome to join us at MSU! We are here to innovate in non-destructive sensing (e.g., machine vision, optical imaging, and spectroscopy) and automation/robotics technologies for addressing practical needs/challenges in agricultural systems encompassing production and postharvest processes. Our goal is to research, develop, and transfer engineering solutions for smart and sustainable agriculture & food systems, especially for specalty crop industries. For prospective students who are determined to work with me, you need to be devoted, proactive, creative, and adaptive, while being willing to go beyond your comfortable zone and embrace challenges. Research is never trivial but a real journey. I am excited to be on this journey with you. My goal is for you as a graduate student/postdoc to grow professionally and enjoy the process of becoming an expert in your discipline. I will strive my best to support you during your academic pursuits and enhance your profession and beyond. If you would like to have a glimpse of my personality, you may read some of my writings (written in Chinese 10+ years ago).

Openings

I am actively looking for motivated PhD (and or MS) graduate students to start in Spring/Fall 2025 in the Department of Biosystems & Agricultural Engineering at Michigan State University. The student will be expected to conduct original research within the fields of sensing and automation for agriculture-food systems. Potential research topics include but are not limited to optical sensing or machine vision for quality assessment, grading, and sorting of horticultural produce and meat, in-orchard sensing & automation of specialty crop production, imaging-based high-throughput phenotpyping, and artificial intelligence (AI) and robotics for precision plant/animal production. Students with engineering backgrounds (e.g., agricultural/food engineering, mechanical engineering, electrical engineering, computer science, etc.) or relevant experience in computer vision and machine learning are highly welcome to apply. Please email me (luyuzhen@msu.edu) with your CV if you are interested.

See the GRA position (in English). See the GRA position (in Chinese).

In additon, I also have Postdoc positions focusing on harvest automation for specialty crops. The position can be started in Fall 2024/Spring 2025 (for an intial one year with possibility of extension). Qualifications for this position include demonstrated experience in machine/computer vision, hardware prototyping, sensors and control, system integration, and strong publication records in engineering journals.

See the Postdoc position.
