C. Research Program

The research in Dr. Zhang's lab focuses on three related fields: molecular genetics, toxicology, and biotechnology.

1. Molecular Genetics and Genome Editing
Dr. Zhang’s lab is using model species (Caenorhabditis elegans and Arabidopsis) and important crops (cotton, switchgrass, sweet potato, and tomato) to study the microRNA-mediated gene regulation and its function in organism growth, development, and response to stressors.  Multiple computational and experimental approaches, including genetic, genomic, transgenic and biochemical methods will be employed. Recent studies have demonstrated that more than 30% of protein-coding genes are targeted by microRNAs (miRNAs), signal-strand small RNAs with 20-25 nucleotides. miRNAs regulate multiple biological and metabolic processes, including development and growth, cell signaling, diseases, and cancers. Currently, miRNAs have become one of the most important gene regulators. Currently, Dr. Zhang’s lab is employing CRISPR-Cas9 genome editing and virus-induced gene silencing (VIGS) technology to knockout/knockdown and overexpress an individual miRNA and protein-coding gene for functional studies.

2. Toxicology and Transgenerational Inheritance
Environmental pollution is a global issue, which can cause numerous diseases in humans and wildlife, including cancers. Dr. Zhang’s lab is focusing on the toxicity and transgenerational effects of several groups of traditional and emerging pollutants, such as nanomaterials, pharmaceuticals and personal care products, explosives, and pesticides. The development of novel biomarkers for rapidly assessing the exposure and health effects of these environmental pollutants would be an important outcome of toxicological study. Dr. Zhang’s lab is also interested in investigating the molecular mechanisms of toxicant/toxin-induced cancers and their chemoprevention.

3. Epigenetics
One of research focuses in Dr. Zhang’s lab is epigenetics. Dr. Zhang is very interested in DNA metalation and its–mediated transgenerational impacts.

4. Biotechnology
Dr. Zhang’s lab also focus on creating new transgenic organisms for producing drugs, biofuels, modifying resistance to abiotic and biotic stressors, and improving crop yield and quality. Dr. Zhang’s lab also interest in the biosafety and risk assessment of genetically modified foods.

H. Prospective Students

Dr. Zhang’s lab is now accepting graduate students (M.S. and Ph.D.) who have an interest in molecular genetics, molecular toxicology, and/or biotechnology. The Department of Biology has a Master of Science degree program and an Interdisciplinary Ph.D. degree program (IDPBS). Currently, graduate students in Dr. Zhang’s lab have the freedom to choose their study organism(s) and system. If you are interested in working with me, you should contact Dr. Zhang directly to discuss the details and possibilities. You may stop by Dr. Zhang’s  office at Science and Technology Building 562  (office) or 535 (Lab) or email Dr. Zhang at zhangb@ecu.edu. Dr. Zhang’s lab is keen on accepting students who are enthusiastic, hard working, and interested in facing challenges and solving questions related to molecular genetics, molecular toxicology, and/or biotechnology. Many graduate students in Dr. Zhang’s lab have won national and international awards and had at least two publications when they graduated.

 

Undergraduate students, particularly freshman and junior,   are also welcome and encouraged to join Dr. Zhang’s lab to gain research experience. If interested, you may also directly stop by Dr. Zhang’s office or email him to discuss possible research opportunities. Many undergraduate students have generated publications as co-authors in Dr. Zhang’s lab.

 

In the next 4 years, both of undergraduate and graduate students working in Dr. Zhang’s lab, have great potentials to travel with Dr. Zhang to China for performing collaborative research.
