Courses Taught

PLPA301 Plant Pathology: Plant pathology is the study of diseased plants. The science of plant pathology involves increasing our understanding of the underlying mechanisms of the disease processes.  The art of plant pathology involves applying that understanding to reduce damage to plants caused by diseases. There are many approaches used to study plant pathology. In PLPA 301, we will focus on the nature of disease-causing agents, the outcomes of the interaction between plants and pathogens, and the general principles we used to control the diseases.  The course includes a review of specific sub-disciplines, such as epidemiology, the genetics of plant diseases, physiological aspects of the disease process, and recent advances in biotechnology for better understanding and controlling plant diseases worldwide.


BESC481 Seminar: Capstone course for topics in bioenvironmental sciences; critical analysis of environmental issues through written themes and presentations. Dr. Shim leads a section that focuses on the critical roles of a manager/director of environmental monitoring or sustainability program in public and private sectors is to develop innovative ideas and propose projects that can achieve meaningful outcomes within acceptable budget and timeframe. Students will seek out an issue of critical significance in global plastic waste and propose a hypothetical microbial bioremediation project that has a potential to innovate how we reduce environmental waste. Students will develop a competitive proof-of-concept proposal that can successfully gain interest and approval.


BESC484 Field Experience (W course): Special problems for advanced undergraduates to permit study of subject matter not available in existing courses. A semester/summer-long professional research experience to expose the student to a professional experience with a government agency (local, state, national, or international) or a faculty-approved research project. This is a university-approved writing-intensive course. The intent of the writing component of this professional experience is to facilitate and improve your ability to: 1) communicate clearly and effectively, 2) demonstrate competence in usage of English grammar, mechanics, in the language specific to environmental professionals, and 3) write in a scientifically correct manner, including citations.

Research Interests

Fungal plant pathogens can cause devastating disruption to the global food supply, and the economic loss due to crop diseases can add up to billions of dollars annually worldwide.  The Shim lab at Texas A&M University is focused on studying plant diseases caused by Fusarium species, which has devastating impacts on agricultural production and food safety. But these pathogens also provide great opportunity for answering many fundamental biological and pathological questions. Notably, hazardous Fusarium mycotoxins pose a significant threat to global food safety and human health.  Crop losses as well as the regulatory, testing, and management costs associated with mycotoxins in the US tops $1 billion annually. We are pursuing research projects that will ultimately lead to innovative tools for controlling maize diseases and mycotoxin contamination. We are also spearheading research initiatives to seek solutions for devastating Fusarium wilts diseases of cotton and watermelon in Texas.


The Shim lab is actively seeking to develop multidisciplinary collaborations with colleagues at Texas A&M as well as other prominent institutions worldwide. In particular, we are extremely excited about our collaborations with Texas A&M Engineering to spearhead innovative projects aiming to seek solutions for environmental waste remediation. One of the recent projects is entitled “High-throughput synthetic biology approaches for mixed plastic degradation and reutilization”, where we will collaborate with researchers in Electrical Engineering (TAMU), Chemical Engineering (TAMU) and Environmental Genomics (U of Oklahoma) to provide a new innovative framework for efficient microbial plastic waste degradation and valorization strategy.
