Post-Doctoral Research Associates
Much of my research interests are centered around understanding the factors that influence the evolution of host-microbe interactions and determine the composition of microbial communities associated with vertebrate hosts (including humans). My main focus is on investigating the potential role of the microbiome in the convergent evolution of phenotypic traits in animals. However, I am currently involved in a variety of projects ranging from understanding the shifts in human-to-home microbial relationships with Westernization to characterizing the composition and function of the microbes found in the myriad ecosystems around the world (i.e. Earth Microbiome Project).
I have been trained as a bioinformatitian in Bielefeld Germany where I acquired a strong background in dynamic programming algorithms and RNA secondary structure prediction. My previous post doc position in Brunswick (DE) introduced me to the field of metagenomics and especially community profiling on whole metagenome shotgun sequencing data. I am eager to upscale current RNA algorithms to match needs of high throughput analyses as in metagenomics and wheel functional RNA into the focus of state of the art research.
Microbiota has tremendous impacts on environment and host health and can be engineered for the better. My interests are mainly centered around linking microbiota composition and function to host phenotypes or environmental factors. I have been working on miscellaneous projects using microbiome as biomarkers for forensics, disease diagnostics and prognostics with statistical and machine learning techniques. Towards that goal, I am also developing new computational tools (e.g. micronota) to improve our understanding of microbial composition and their functions.
I have a background in chemistry and structural bioinformatics, with experience in computational chemistry, computer-aided drug design and protein structure predictions. My efforts in the lab concentrate on expanding our knowledge of the microbiome by annotating metagenomic information and microbiome-wide protein structure and function predictions.
My research focuses on the microbiome of the armpit, skin, clothes and washing machines, in relation to (mal)odor formation. We try to improve one’s body odor by performing an armpit bacterial transplantation, where bacteria from a non-odorous armpit are brought onto the washed armpit of a smelly armpit. I have a background in applied biosciences and bioengineering and obtained my PhD at Ghent University in Belgium. More details can be found in the website below.
I am currently a Post-doctoral Research Associate in the Knight Lab.
The relationships we have with our microbial denizens have important consequences. But how have those relationships evolved? My research starts with exploring the diversity of animal-associated microbes in the present day, and then seeks to use those associations to make inferences about their histories. Ultimately, these stories should teach us something about the rules governing these complex communities, allowing us to make more informed decisions about their preservation and management.
I have a mixed background in experimental biology and bioinformatics. My main interest is shotgun metagenomics, including taxonomic and functional profiling, de novo assembly, binning, and draft genome finishing. I am also interested in evolutionary biology, especially in host-parasite co-evolution and horizontal gene transfer.
Professional Research Assistants
I moved to Rob's lab in 2011, where I have accepted responsibility for many things. This includes IRB, IBC and IACUC protocols. I assist with metadata curation and upload of projects to the database.
I have been working with the Knight Lab since 2009 and I am currently in charge of wet lab processing and the sequencing queue. I am interested in temporal variability of the microbiome and micro culturing.
My research emphasis is on the development of computational methods that enable analysis of microbiome data at scale irrespective of the environment (although poop is fun). I am a core developer on many of the software projects the lab is involved in, and have a strong interest in open source and open access processes. I am a former American Gut project manager overseeing the effort from June 2013 to August 2015 including its expansion into the British Gut and an Australian aggregation site.
I joined the Knight Lab in 2015, and I work in the wet lab where I assist our talented team in preparing samples for NGS applications. I received my M.S. in Biology from San Diego State University, and my B.S. from Saint Mary’s College of California. I am most interested in human-microbe interactions, especially in regard to the gut-brain axis. I am particularly excited about the potential that microbiome research and innovation has in addressing aspects of generally treatment resistant psychiatric conditions such as PTSD, schizophrenia, certain depression and anxiety disorders, and a whole host of other maladies.
My main interest is developing new computational methods to compare large numbers of microbial communities and to put these comparisons in a temporal and spatial context, with the ultimate goal of understanding and controlling microbial communities to improve health in different environments. I have worked on many projects in environments from soils to the human body, leading to the development of novel analysis methods and software packages including QIIME, Qiita, SitePainter, Emperor, and Evident.
I joined the Knight lab because of my interest in the current and future projects, and also to gain experience in preparation for grad school. My background is in Decision Science and Physiology, but I am excited to learn more about the connection between microbiota and the mind/mental health. I currently work in the wet lab, assisting with sample processing.
I contribute to the work involved with processing samples in the wet lab. I obtained my bachelors degree in University College Cork, where I specialized in microbiology. I have keen interest in the relations between the microbiome and various diseases such as parkinson’s, multiple sclerosis and cancer, and also in the development of personalized medication. In the future, I would like to perform field research in various parts of the globe and I plan on attending grad school.
I’m a UCSD recent graduate that refuses to leave campus. I joined the Knight Lab because I have a deep interest in lab automation and high throughput systems. I am a fan of robotics that constantly pursues replacing monotonous human labor with hands off experimentation.
My primary focus is the American Gut project, including facilitating participation and helping to guide participants through the process of understanding their microbiomes.
I have been a part of the wet lab since March, 2015 and help process samples for all types of projects. I earned my BS from UC San Diego in Physiology and Neuroscience and am currently working on my Masters in Biology with Dr. James Nieh. My research is on the effects of neonicotinoid pesticides on honey bee foraging behavior and the impacts on food web interactions. When I am not in the lab, I love to surf, travel, and backpack.
I'm currently in my last year of Undergrad at UCSD studying General Biology, and compete for the ICA Swim Team. I assist with sample processing in the wet lab. In the future I hope to attend medical school and further specialize in Functional Medicine, and am interested with how the microbiome affects our health.
I’m a PhD student in Biomedical Sciences, co-advised by Dr. Rommie E. Amaro in Chemistry. I use tools from the fields of computational chemistry and biophysics (protein folding, molecular dynamics, Markov state models, and more) to investigate microbial proteomes and elucidate the function of the microbiome.
I'm currently a PhD student in Computer Science. I've been always interested in High Performance Computing and Data visualization, and searching ways to apply this to improve people's life. When I joined the Knight Lab in Spring 2012, I found Computational Biology the perfect mix of my two passions. My research is mainly focused on the development of the software package Qiita, sequence clustering, new high-performance visualization tools and analysis of datasets that push the limit of current analysis techniques.
I’m a Biomedical Sciences PhD student, co-advised by Dr. Victor Nizet. My primary research focus concerns the interplay between host microbiota and the development of antibiotic resistant pathogens. Additionally, I’m interested in investigating the role of commensal microbiota in the development of systemic immunity.
I’m a PhD student in Marine Biology at Scripps Institute of Oceanography co-advised by Eric Allen. My primary interest is in solving food security problems through sustainable aquaculture. Microbes are linked to aquatic host health through disease and nutrition, and thus can be used as diagnostic markers to predict ecosystem collapse or as an intervention for promoting health. To answer these questions, I’ve helped develop methods for high throughput metagenomics for low biomass samples (e.g. the built environment) and will continue to seek out new and interesting opportunities in biotechnology.
I'm a graduate student in the Computer Science and Engineering department. I am interested in analyzing high dimensional and large datasets, most of my experience has been with data that links the human microbiome to health. For more information about me, see my personal website below.
I am a graduate student in the Biomedical Sciences program co-advised by Dr. Karsten Zengler. My current project focuses on isolating anaerobes for functional experiments on the skin microbiome.
I'm a PhD student in the Department of Biology. I am interested in ecological and evolutionary interactions within the microbiome, especially phageome-microbiome dynamics and mobilization of multi-drug resistance in poly-microbial communities. Other interests include niche modelling, synthetic microbiota design and mind & microbiome.
I'm currently a PhD student in the Computer Science and Engineering program.
I'm interested in developing algorithms and statistical theory to better understand microbial ecosystems.
Currently, I am involved with the American Gut project and Emperor.
I'm pursuing a PhD in the Biomedical Sciences Program. Co-advised by Dr. David Gonzalez in the department of pharmacology, I aim to utilize proteomics to study the microbiome. I'm interested in how a change in the microbiome mediates disease states and to what extent the host is altered by these fluctuations.
I am a PhD student in Biostatistics in the Department of Family Medicine and Public Health. My interest is in performing high-level analysis of microbiome data to better understand the relationship between microbial world and human health, and in developing new statistical and mathematical methods to bring more insights into the analysis of high dimensional data.
