Lisa Couper (Graduate Student)
I am a graduate student in the Biology department interested in infectious disease ecology. My research focuses on how climate change affects vector-borne disease dynamics, and how vectors may adapt to changing temperatures. My prior work has focused on tick microbial ecology, and the drivers of variation in Lyme disease incidence in the US. I completed my undergrad at UNC in Environmental Science where I studied the effects of human land use on coastal phytoplankton communities.

Lucas Czech (Postdoctoral Fellow)
Lucas is a computer scientist and bioinformatician who is interested in analyzing and visualizing biological data. His goal is to develop and apply novel methods that help biologistis and ecologists to make sense of life and nature. Hence, he focusses on algorithm and software development, with a particular interest in machine learning and high performance computing. During his studies, he also gained experience in areas such as speech recognition, cryptography, and physics. During his PhD, he worked on novel methods to analyze metagenomic data in a phylogenetic context. In the Moi lab, his first postdoc position, he wants to develop and implement new ways to integrate biological data with other sources of information such as satellite images. His goal is to help understanding the patterns and interactions that govern ecology and evolution, from mutations in DNA to transformations of landscapes, in the global context of climate change.

Shannon Hateley (Postdoctoral Fellow)
Shannon Hateley is a computational biologist interested in using genomics methods to understand organismal response to climate change. Prior to coming to Carnegie, she was a senior staff scientist at AncestryDNA. Dr. Hateley obtained her Ph.D. in Molecular and Cell Biology from University of California, Berkeley, with a designated emphasis in Computational and Genomics Biology. During her studies, she worked both at lab bench and computationally on gene expression, building tools for RNA transcript characterization, and detecting disease-associated genetic variants. Dr. Hateley also holds a B.A. from St. John’s College where she studied the Great Books. She spends her free time on dance, tinkering, and climate organizing.

Yunru Peng (Lab Technician)
I graduated from UC Berkeley in May 2019 with a BSc in microbial biology and an emphasis in computational genomics. I am interested in genetics and genomics. During my undergraduate, I used a novel CRISPR/Cas9 multiplex editing technique to modify soybean genome, aiming to enhance the plant's immunity. I also worked in projects related to microbial and zebrafish genetics. I think of genetics as a unifying lens to examine the rich biodiversity and evolutionary history on Earth. At Moi Lab, I will examine the genomes of evolving populations and develop CRISPR tools for polygenic editing. Outside of research, I like books, games, and the outdoors.

Megan Ruffley (Postdoctoral Fellow)
I am interested in using machine learning algorithms to understand selection across plant genomes in response to stress. I received my PhD in Bioinformatics and Computational Biology at the University of Idaho where I focused on performing simulation-based model inference using machine learning algorithms in areas ranging from demographic inference and phylogenetics to community-wide assembly mechanisms. This research was concentrated on disjunct plants of the Pacific Northwest temperate rainforest, but also focused on community-wide plant ecosystems, such as island plant communities. I am currently interested in continuing to apply machine learning algorithms to novel problems in evolutionary biology that can aid in solving our world’s most challenging problems. In the Moi and Rhee labs, I continue to investigate these algorithms as I study the relationship between genetic adaptation and response to stress in economically and agriculturally important crop plants. Investigating such adaptations to stress aid in our struggle to understand the future impacts of climate change.

Sebastian Toro Arana (Graduate Student)
Sebastian is interested in using computational tools and engineering principles to study the underlying mechanisms of plant stress resistance, immunity and plant-microbe-environment interactions. His goal is to use new technologies to help tackle the challenges of climate change and food security. As an undergraduate and research technician at MIT, he worked on exploring brain decision making systems using computational analysis tools and genetic engineering but recently he has decided to work on more pressing global problems. On a more personal note, he loves enjoying nature and music.
