Research scientist
Resume:
My ** years previous experience as a research scientist and principle
investigator for molecular genetics and animal genomics areas is fitted for the position. In addition, I can maximize outcomes with other members if I join the team. Believe me.
The followings are my brief summary for the experience as a scientist. After finishing my Ph.D. at the Ohio State University majoring in Animal Genetics, I have worked at National Institute of Animal Science (NIAS) in Korea for 24 years as a senior researcher who is in charge of Animal Bioinformatics and Genomics Division. Due to immigration of my family from Korea to US I have quit my position at NIAS, and I have just got here in Rockville, MD in 2017. I am thinking that I may do research works in your institute with great fast learning techniques.
Here is what I have done regarding research projects before come to US. At the time I joined the laboratory of Dr. Michael Davis at OSU, I liked to find causative genetic mutations that may be significantly related to quantitative traits for beef cattle. Actually, searching genetic variants in a specified genomic region was so challengeable due to difficulty and time consuming when the identified genetic variants were not associated with the targeted traits. However, many studies try to find genetic mutations using a huge amount of sequence data, and now, it is kind of easy to find causative variations with advanced statistical procedures. Searching genetic mutations regarding economically important traits for domestic farm animals was my major concerns in research.
I have completed a project that was designed to complete genetic maps for swine leucocyte antigen (SLA) regions, approximately 2 Mb. The basic target of the project was for construction of miniature pig lines using SLA genotypes, and the pigs were used for bio-organ transplantation. Thus, we need precise and robust genotypes that can be used to maintain pig lines. In addition, the analysis of big data also should be kept going, and I am eager for drawing physical maps of genome related to QTLs. More recently, many studies use big data and share particular data sets from the specified web sites. Therefore, comparative genomics for both analyzing causative genetic variants and genetic relationships among individuals as well as breeds in the world was my favorite research topics. More recently, I have done comparative genomics with massive amount genome data of gut microbes using 16S RNA sequences to identify phylogenetic relationships that can identify what kinds of microbes actually influenced development of rumen cells. Characterization of specific rumen microbes can be used for feeding systems as an additive. I have analyzed massive amount of SNP data sets for bovine, swine, and chicken regarding quantitative and qualitative traits. For beef cattle, both 50K and HD SNP chips are used to find genome wide associations with the meat quality trait, which is the major issue in Korea. Associations between genetic variants and pH level in swine and weights in chicken. When I joined the functional genomics laboratory of Dr. Erin Connor at USDA, she and I tried to find expression levels of genes that were related to feed efficiencies of Holstein cows. I have also used different formats of the expressional design that was focused on finding significant genes related to expression levels when different levels of energy diets are administrated according to the developmental stages using Korean cattle. Moreover, finding differentially expressed genes are extremely fantastic areas to study, and so, I was trying to find genes that are differentially responded for heat stress using cows and chickens. For the analysis of heat resistance, transcriptoms using both RNAseq and Mediseq are screened for Holstein cattle and using Korean chicken in my side, and African chickens are analyzed by Dr. Steve Camp who is working at ILRI (International Laboratory Research Institute, Kenya). Currently, I am in editorial boards for the scientific journals “GENE” and
“Korean Animal Science and Technology” as an associated editor and section editor, respectively. I eager to do research work with adapting new techniques in your institute if possible.
