Alexander Boiko-cropAlexander Boiko, Molecular Biology and Biochemistry, Assistant Professor

Dr. Boiko received his Ph.D. degree in the area of molecular biology and cancer genetics from the University of Illinois at Chicago, where he worked in the laboratory of Dr. Andrei Gudkov on the molecular mechanisms of p53 mediated tumor suppression. In 2006 Dr. Boiko moved to Stanford University and joined the laboratory of Dr. Irving Weissman as a postdoctoral researcher. There he used human surgical melanoma samples along with advanced methods of cell isolation and transplantation to identify human melanoma tumor initiating cells based on the expression of neural crest stem cell marker CD271/NGFR. Currently, Dr. Boiko continues to study cellular/molecular origins of melanoma initiation and clonal progression, as well as, trying to determine factors underlying aggressive metastatic properties of this disease in his own laboratory at the University of California-Irvine. Alexander is avid tennis and chess player; his other personal interests include astronomy, arts, traveling and hiking.

J.J. Emerson, Ecology and Evolutionary Biology, Assistant Professor

Dr. J.J. Emerson is broadly trained in topics including ecology and evolutionary biology, genomics, and biochemistry. Dr. Emerson is interested in the evolution of genomes and uses statistical and computational approaches in studying large datasets to address topics in molecular evolution and population genetics. While Dr. Emerson focuses on model systems like the fruit fly Drosophila and the yeast Saccharomyces, he has also worked on human, mouse, chicken, ciliates, fish, and snakes. He received two BA’s (2000) in Ecology & Evolutionary Biology and Biochemistry at Rice University, graduating magna cum laude. He did his doctoral work at the University of Chicago in the Department of Ecology & Evolution, earning his PhD in 2006. He was the recipient of the Distinguished Postdoctoral Research Fellowship in the Genome Research Center at Academia Sinica, in Taipei, Taiwan, where he worked from 2006-2010. While at Academia Sinica, Dr. Emerson developed statistical methodology to use newly developed sequencing technology to investigate the evolution of gene expression patterns in yeast. In 2010, Dr. Emerson accepted a second postdoctoral position at UC Berkeley’s Department of Integrative Biology to work on the evolution of sex chromosomes, where he has investigated how sex chromosomes differentiate and has developed statistical models for finding sex chromosomes using high throughput sequencing technology.

Yilin Hu-small headshot web Yilin Hu, Molecular Biology and Biochemistry, Assistant Professor

Yilin Hu received a B.S. degree in Genetics and Genetic Engineering from Fudan University, China and a Ph.D. degree in Biochemistry from Loma Linda University. She was a postdoctoral fellow and project scientist before she became an assistant professor in the Department of Molecular Biology and Biochemistry at the University of California, Irvine. During the last 12 years, she has been focusing on studies related to nitrogenase mechanism and assembly, with an emphasis on the genetic manipulation of nitrogenase enzymes. She is currently expanding her research into investigations of enzyme systems involved in photosynthesis and methanogenesis that are related to nitrogenases during evolution. These efforts aim at establishing an evolutionary link between nitrogen fixation, methanogenesis and photosynthesis from a biochemical perspective and developing strategies for industrial applications of these processes based on the intrinsic homology among these enzyme systems.

Dr. Sergio Rasmann is a broadly trained biologist who is interested in the ecology and evolution of plant traits that confer resistance against insect herbivore or pathogen attack. Sergio Rasmann has worked in many different habitats including cornfields of Hungary, deciduous forests of Easter North America, the Mediterranean coast of Chile and the Swiss Alps, studying the mechanistic underpinning of plant defensive strategies for better crop protection, and how plant and animal communities are evolving during current climate change.

He received a B.S. (2001), and a M.S. (2002) in Biology at the University of Neuchâtel in Switzerland. At the same University, he earned his Ph.D. in 2006 working on below ground plant-herbivore-predator interaction. After the Ph.D., he spent one year doing developmental aid in Bolivia, and in the meanwhile obtaining a post-doctoral fellowship to deepen his interests in the evolutionary mechanisms of plant herbivore interaction at Cornell University in upstate NY. In 2011, he became research associate at the University of Lausanne in Switzerland. He has served as primary advisor for six master-students, two post-doctoral students, several undergraduate students, and has served as external supervisor of four Ph.D. students. The Swiss Science Foundation has mainly supported his research. He is excited to join the faculty of Ecology and Evolutionary Biology and help the department’s research, teaching and engagement missions.

Dr. Razorenova received her Master’s in Molecular Genetics from Lomonosov Moscow State University

(Russia) in 2000. She started her PhD program in the area of Molecular Biology at the Engelhardt Institute of Molecular Biology in Moscow the same year. Olga was fortunate to work both in Russia and in USA, at the Department of Molecular Genetics at the Cleveland Clinic, during her Graduate years under Dr. Chumakov’s supervision. Olga’s thesis was on dissecting p53-dependent transcription of target genes, and its downstream signaling pathways in melanoma. To broaden her research experience, she started working in the field of angiogenesis, with specific emphasis on tumor angiogenesis. The main focus of her studies was integrin-mediated signaling, which she conducted in Dr. Byzova’s laboratory in the Department of Molecular Cardiology, Cleveland Clinic. Olga got her PhD in 2006 and started her postdoctoral training in Dr. Giaccia’s laboratory in the Department of Radiation Oncology at Stanford University. She has been leading the projects concerning the impact of hypoxic tumor microenvironment and hypoxia inducible factor (HIF) on the regulation of transcription of genes contributing to tumor metastasis. Olga has taught several biology classes for Stanford’s educational program (SPLASH) and has mentored multiple students throughout her research career in the lab. Her personal interests include jewelry making, dancing, reading, attending concerts and art exhibitions, traveling.

New Bio faculty- Justin Schaffer headshotJustin Shaffer, Developmental and Cell Biology, Lecturer PSOE

Dr. Justin Shaffer is joining us at UC Irvine with the goals of studying and maximizing student learning in biological sciences courses. He recently completed a research and teaching postdoctoral fellowship at the University of North Carolina in Chapel Hill where he not only performed research studying the molecular mechanisms of muscle contraction in marine cephalopods, but he also was trained in modern pedagogical techniques and student-centered learning. Justin put this training to use by developing and teaching courses at North Carolina A&T State University and at UNC Chapel Hill. Prior to his postdoc, Justin received his PhD in Bioengineering from the University of Washington in Seattle where he studied the molecular, biochemical, and biophysical interactions of cardiac contractile proteins in models of heart disease. Now as a Lecturer PSOE at UC Irvine, Justin will focus on developing and teaching student-centered non-majors and majors biological sciences courses, studying the development and retention of scientific literacy skills in students, and training graduate students and postdocs to be excellent teachers and mentors.

Profile_Sun_S-262x300Sha Sun, Assistant Professor, Developmental and Cell Biology

Sha Sun, Ph.D. received her degree from Harvard University.

Research interests: Long noncoding RNAs in epigenetic programming. The general interest of the Sun laboratory is to understand how a living cell controls its genetic and epigenetic composition. The main focus of her research involves the functional roles of long noncoding RNAs(lncRNAs) in epigenetic programming. Increasing evidence from large-­? scale transcriptome sequencing projects suggests a high abundance of lncRNAs present in human genome and potentially significant roles of lncRNAs in various aspects of biological processes.
