Maude M. David

Assistant Professor, Departments of Microbiology and Pharmaceutical Sciences. maude.david@oregonstate.edu @Mo2Dav

Dr. Maude M. David received her PhD in 2010 from Centrale Lyon, in France. Her work focused on environmental microbial ecology and next generation sequencing. After graduation, she became a post-doctoral fellow at Lawrence Berkeley National Laboratory. She studied the impact of climate change on different microbial systems, where she developed new computational tools for the analysis of microbial metagenomes. In 2014, she moved to Stanford School of Medicine, applying her biocomputing expertise to studying Autism Spectrum Disorder (ASD). She looked at the impact of the gut microbiome on ASD, as well as evolutionary constraints on the human genes involved in this disorder. She joined Oregon State University as an Assistant Professor in January 2018, where she combines laboratory and computational techniques to unravel the underlying mechanisms of the gut-brain axis. She has a joined appointment in Microbiology and Pharmaceutical Sciences.

 

GRADUATE STUDENTS

 

Christine Tataru

Christine Tataru received her Master's in Computer Sciences in June 2018 at Stanford University. She started her PhD in the laboratory in September of 2018, and is the recipient of OSU Provost’s Distinguished Graduate Fellowship. She has begun optimizing emerging machine learning algorithms to both denoise and extract meaningful information of massive sequencing datasets generated by the laboratory and the rest of the scientific community. Ultimately, she seeks to develop tools and frameworks to advance microbiome research, then use those tools to explore gut-brain axis phenomenon. Christine is the recipient of the OMSI Science Communication fellowship which will teach her about science communication methodology and help her to invent a relatable, hands-on demonstration explaining the concepts behind her modeling work. In her free time, she enjoys hiking with her dog Skye, listening to audio books and podcasts, and riding horses! You can find her blog here. 

 

Grace Deitzler

Grace graduated with a B.S. in Biological Sciences from Missouri University of Science & Technology in 2016. She joined the David lab as a PhD student in the spring of 2019 after a couple of rotations. She is a recipient of the National Science Foundation's Graduate Research Fellowship. Grace has been instrumental in pushing forward the behavior testing with rodents, and our bee microbiome project. Among other skills, Grace's incredible capabilities in using the very last cmof nitrogen in the anaerobic chamber saved multiple days of labor for the all lab, and allowed her to extract over 80 samples just before Christmas. Outside of the lab, she is a co-founder and leader in Seminarium, an interdisciplinary organization dedicated to the intersection of Art and Science. You can follow her journey in science on Twitter at @dna_heligrace.

 

 

Priyanka Singla

Priyanka joined Oregon State University in September 2018 as a master's student within the program of microbiology. She is a recipient of the Tartar Family Graduate Fellowship and Joan Countryman Suit Graduate Scholarship. In the lab, she maintains mice colonies, performs mice behavior testing and genotyping. Her expertise lies in culturing eukaryotic cell lines. Currently, she is working on optimizing the isolation and culturing of primary gut sensory cells from mice intestines and vagal neurons from the nodose ganglion. In her spare time, she enjoys spending time with her friends and family. She also enjoys cooking and baking.                         

 

 

RESEARCH ASSISTANTS

 

Austin Martin

Austin graduated from a B.S. in Microbiology at Oregon State University this spring. He is was a member of the Honors College, and was the recipient of the College of Sciences' SURE fellowship (Summer Undergraduate Research Experience) for 2018, and the College of Pharmacy Undergraduate Summer Research Scholarship.  He has been working on analyzing public microbiome 16S datasets related to anxiety and its comorbid disorders. He is also developing online tools that will be used in a crowdsourced study on anxiety currently being implemented by the laboratory. Outside the lab, Austin is a member of the Oregon State Running Club and represents OSU in track meets during the spring.

 

 

Alexandra Phillips 

Alex graduated in 2020 with a B.S. degree in Biochemistry and Molecular Biology with a chemistry minor from Oregon State University. She is currently serving as a lab technician and works taking care of the mice colonies, performing behavior experiments and among other projects in the lab, she is assisting in the development of a microbial biosensor to be used for water quality testing. Alex plans on attending a graduate school program in the next year. Her research interests include studying the microbiome in the context of human disease and neurodegenerative disease mechanisms. During her free time, she enjoys spending time with her family's horses, playing board games with friends, and learning to cook new foods.

 

 

UNDERGRADUATE RESEARCHERS

Annabel Martin-Varnum

Annabel is a junior in the Bioengineering Program at Oregon State University, and an undergraduate worker in the lab. She is interested in neuroscience and currently works as a research assistant in the lab. She takes care of the mice colony, performs behavior testings and assists Priyanka in the optimization of primary cell cultures and nodose ganglion dissections. She has also been learning electrophysiology at the OSU core facilities. Annabel has been selected to participate in the University of Washington's Center for Neurotechnology Summer REU program this year. When she is not working in the lab you will find her studying with friends, at the gym, or hitting the slopes. 

 

Sonica Gupta

Sonica just graduated from a B.S. in Computer Sciences at Oregon State University. She also is a member of the Honors College and was the recipient of a fellowship from the College of Pharmacy Summer Research program. Sonica is currently developing new Hidden Markov Models (HMM) for metagenomic shotgun sequencing annotations from microbiome datasets. She has also been working on developing GUI interface to spread the use of these HMMs.

 

 

 

 Teminijesu T. Adewunmi

Temi is a sophomore studying Computer Science at Oregon State University and is a URSA Engage recipient for 2020. She is interested in bioinformatics and currently works as an undergraduate research assistant in the lab. She helps Sonica with her project by running Pfam-Sequences and getting the total number of sequences in a file. During her free time, she enjoys crocheting, reading, and baking.   

 

 

 Maya Livini 

Maya is a first-year undergraduate pursuing a B.S. in Biochemistry and Molecular Biology at Oregon State University. She is a member of the Honors College, a 2020 URSA Engage recipient, and a SURE recipient for Summer 2020. She has been learning how to take care of the mice colonies and assisting Priyanka and Annabel with their project by learning cell sorting and will soon learn DNA tissue extractions to assist in other ongoing projects.
