I joined Dr. Dassanayake’s lab in 2014 Fall for my Ph.D. degree. Currently, I am working on two different projects using molecular biology methods and comparative genomics.One project is to confirm that some structurally different genes identified between Schrenkiella parvula(Sp) and Arabidopsis thaliana(At) by our lab lead to different responses of At and Sp to high concentrations of B3+/Na+/Li+ and identify the potential regulation mechanism.The second project is to identify differences between the genomes of Schrenkiella parvula, Eutrema salsugineum and Arabidopsis thaliana differing in terms of their responses to salt, and identify the differences in their responses to salt stress and the genes associated with these differences.And other collaborations include: (1) the identification of SNPs, small INDELs, and SVs between the genomes of cultivated and weedy rice and, more importantly, candidate genes associated with target traits(seed dormancy and seed shattering) ;(2) the analysis of differentially expressed genes between control and Urate-treated Burkholderia thailandensis.
I joined Dr. Dassanayake’s lab in 2015 fall as a Ph.D. graduate student. I am working in Arabidopsis and its related extremophile (Schrenkiella parvula) to study abiotic stress tolerance. I am using modern molecular biology and comparative genomics tool.
I completed my MS from University of Arkansas at Pine Bluff in 2015 May. I worked on down-regulation of lignin biosynthetic genes particularly Cinnamyl Alcohol Dehydrogenase (CAD) and Cinnamoyl-CoA Reductase (CCR) in big bluestem grass, a potential feedstock for biofuel.
I completed my undergraduate degree from Institute of Agriculture and Animal Science (IAAS), Nepal in 2012.
I graduated from LSU with a bachelors degree in Biological Science in 2015. My passion for science has drawn me into this lab research. I am currently working with three research model plants: Arabidopsis thaliana, Schrenkiella parvula, and Eutrema salsugineum. Schrenkiella parvula (Spa), an extremophyte crucifer found in the shores of the hypersaline lake Tuz of central Turkey, can complete life cycle in the presence of high salt concentrations of Na+, K+, Li+, and borate that are lethal to most plant. Eutrema salsugineum (Esa), another closely-related halophyte crucifer, shows increased tolerance specific to Na+ salt stress but no different responses to other ion toxicities, compared to the highly salt-sensitive Arabidopsis thaliana (Ath). Despite of the different evolutionary paths and adaptive strategies, genomes of these three species share ~70% of gene models as homologous and colinear, enabling a three-species comparative analyses. My goal is to identify different modules of transcriptomic responses of Spa, Esa, and Ath, in responses specifically to Na+ , and Li+ stresses that enable the plants to survive in such unfavorable conditions. Besides school, I'm interested in traveling and learning different languages. Federick Douglass once said: " if there is no struggle, there is no progress."
I joined Dr. Dassanayake’s lab in 2016 Fall for my Ph.D. I am interested in uncovering the mechanisms, which plants have acquired over millions of years, that give them the ability to survive in extreme environments using genomic, molecular and computational tools. I have focused my studies on how post-transcriptional regulation of gene expression is fine tuned in halophytes, enabling them to conquer extreme habitats. Model species I am currently working on are Schrenkiella parvula and Arabidopsis thaliana.
My name is Jordan Vivien and I am a junior majoring in Biological Sciences and I am planning to go to veterinary school. I am working in Dr. Dassanayake's lab under a scholarship, but I am excited to learn about and understand the research being done during the time that I am there.
I'm a junior biochemistry major, and I started working in Dr. Dassanayake's lab in August of 2018. I personally have an interest in cancer research as a career, and I'm very grateful for the undergraduate research platform I'm working towards as a President's Aid Recipient! I've learned how to sterilize seeds, make plant growth media, grow and maintain plants on soil, and select putative transgenic plants!
I am a sophomore majoring in Biological Science. I joined Dr. Dassanayake's lab to widen my knowledge in the field of science. I am excited to learn from the experience and from the other lab workers. I enjoy reading and watching films during my free time.
I am a sophomore microbiology major at LSU. I am very new to lab work but I am eager to learn, especially about tools like CRISPR. Outside of the lab, I occasionally do volunteer work for local organizations in between studying, classes, and training at the UREC
I just started as a sophomore at LSU as a pre-med biochemistry major. I discovered Dr. Dassanayake's lab through the BIOS program on a lab tour and became very interested in the lab's work. It will be very interested to learn the practical processes of the lab as well as the results of altering plant genes. I am a big science guy who was born and bred for science, so this will be very exciting.
My name is Ashley Doan and I am a freshman majoring in Biological Sciences with a minor in Textiles and Fashion Merchandising. I joined Dr. Dassanayake’s lab because I wanted to gain more experience in lab work and research and ultimately broaden my knowledge about biology. I am also interested in how this research correlates to the rapidly changing environment. I have learned a lot of things so far in the lab, such as sterilizing seeds and growing and maintaining plants. Outside of the lab, I enjoy watching documentaries and going to the UREC.
My name is August Steinkamp, I am a freshman majoring in microbiology with an interest in medicine. I am currently being trained to work in Dr. Dassanayake’s lab through PFLR. I am extremely interested in the medical potential of stem cells. Outside of science, in my spare time I enjoy playing guitar, cooking, and running.
