David Taylor, Ph.D.
Principal Investigator
David is an Associate Professor in the Department of Molecular Biosciences. He started as an Assistant Professor at UT Austin in September 2016. He earned his Ph.D. at Yale University and performed postdoctoral training at UC Berkeley with Eva Nogales and Jennifer Doudna. He has a passion for RNPs. He loves the Warriors, Syracuse basketball, teaching, and ‘starting’ projects that other lab members actually finish.


Helen Chen, Ph.D.
Research Associate and Lab Manager
Helen joined the lab as Research Associate/Lab manager in October 2016. She got her Ph.D. in Biochemistry at Texas A&M University with Dr. James Sacchettini. She enjoys gardening and cooking in addition to Science.
Jack Bravo, Ph.D.
Post-doctoral Researcher
Jack joined the group as a postdoctoral researcher in early 2020, having completed his Ph.D. at the University of Leeds, UK in 2019. During his Ph.D., he used various structural and biophysical approaches to understand the molecular mechanisms of RNA chaperone proteins involved in virus assembly. Jack is particularly interested in using cryo-EM to understand the inner workings of various biomacromolecular machines, with a particular focus on bacterial nucleoprotein complexes. Learn more…


Isabel Strohkendl, Ph.D.
Post-doctoral Researcher
Isabel joined the group in the summer of 2021 after completing her PhD at UT. Her dissertation work focused on class 2 CRISPR effectors, using kinetics-based assays and a biophysical approach to characterize the DNA targeting specificity of these RNA-guided nucleases. Isabel is interested in learning cryo-EM to uncover how CRISPR effectors assemble with their guide RNAs and how these contacts influence DNA targeting behavior. When not in lab, Isabel enjoys fun under the sun.
Roisin O’Brien, Ph.D.
Post-doctoral Researcher
Roisin loved being a graduate student in the Taylor lab from 2017-2022 so much that she decided to continue as a postdoc here ever since. She loves to use cryo-EM to study the structure and function of large CRISPR-Cas complexes. Before coming to UT, she graduated with a Biochemistry degree from the University of San Diego, while completing research and working at a biotech company. In her free time, she loves to run around Austin’s beautiful Lady Bird Lake and do yoga with her dog.


Jamie Yelland
Graduate Student (Joint with Professor Arlen Johnson)
Jamie is a graduate student in the ICMB Biochemistry program, jointly advised by David Taylor and Arlen Johnson. He studies the structures of intermediates of ribosome synthesis, with a particular interest in learning more about enzymes that are critical for proper formation of ribosomal subunits. Jamie earned a B.A. in Biochemistry from Oberlin College in 2013. He is an avid long distance runner and enjoys an occasional bout of fly fishing.
Grace Hibshman
Graduate Student
Grace joined the Taylor lab as a graduate student in June 2021. She completed her B.A. in Molecular, Cellular and Developmental Biology with a certificate in Neuroscience at the University of Colorado at Boulder in 2020. There she studied the higher order structures of telomeres using atomic force microscopy, as well as TERT activation in metastatic cancers in the laboratory of Thomas R. Cech. Now, her research focuses on understanding the molecular mechanisms of novel CRISPR-Cas complexes through structural and biophysical methods. In her free time, she enjoys exploring the green spaces and live music Austin has to offer.


Jacquelyn Wright
Graduate Student (Joint with Professor Daniel Dickinson)
Jacquelyn is a Biochemistry graduate student who joined the Taylor and Dickinson labs in the summer of 2021. Before UT, she earned a B.S. in Chemistry on the Biochemistry track with a second major in Spanish and Hispanic Studies at Creighton University in 2020. While working there in Dr. Lynne Dieckman’s lab, Jacquelyn developed a TIRF microscopy system to investigate an interaction of two proteins that functions in gene silencing. Her work at UT focuses on using fluorescent microscopy methods to better understand the biophysics and mechanisms of CRISPR-Cas systems. Outside of the lab, Jacquelyn loves exploring food around Austin and spending time outdoors with friends and her dog.
Matt Hooper
Graduate Student
Matt joined the Taylor Lab as a graduate student in January 2022. He earned a B.S. in Neuroscience with a certificate in Business from The University of Texas at Austin in 2019. After graduating, Matt spent 2 years working as a Research & Development scientist at the biotechnology company, PerkinElmer, before returning to UT. Currently, he is interested in understanding the structural and functional mechanisms of naturally occurring and engineered CRISPR-Cas systems. Outside of lab, Matt enjoys writing music, playing video games, and all forms of true crime media.


Zeyi (Joey) Yu
Graduate Student
Joey joined the Taylor Lab as a graduate student in January 2023. He earned a M.S. in Medicinal Chemistry from Sun Yat-sen University in 2022. There he studied specific secondary structures of nucleic acids G-quadruplexes by using fluorescent microscopy methods. Currently, he is interested in understanding the structural and functional mechanisms of novel CRISPR-Cas systems through cryo-EM. In his spare time, he loves playing ultimate frisbee, bouldering, and watching live music shows.
Delisa Ramos
Research Technician
I graduated from UT with a B.S. in Biology and certificate in Applied Statistical Modeling. I joined the Taylor lab in 2019 and currently work on resolving the structures of anti-crispr proteins targeting Type I-C crispr-cas complexes. Outside of lab, you can find me cycling around Austin’s hill country, doing yoga, or trying out new recipes.


Catherine Moy
Research Technician
Catherine joined the Taylor Lab in April 2022 right before graduating from UT with a B.S. in Biochemistry and a B.A. in Spanish. Currently, she is studying mutations in Cas12a to improve its fidelity and efficiency. When she’s not in the lab, she enjoys running around the Hike and Bike trail, sampling new Austin eats, and trying to convince her dogs to fetch frisbees. She unfortunately had David for BCH370, but she decided to join anyway (added by DT).
Shashwat Limbasia
Undergraduate Researcher
Shashwat joined the Taylor Lab as an undergraduate research technician in the Fall of 2021. He graduated from TAMS in Spring 2021 and is now a Neuroscience major at UT. He is working on characterizing the mechanisms and structures of novel CRISPR-Cas complexes for improved targeting. In his free time, he likes to go bouldering and explore Austin with his friends.


Zachary Ryan Taylor
Vice-President for Emotional Support
Zach loves long walks, chasing squirrels, and all members of the Taylor lab. He does not like other dogs. He provides counseling services in his spare time.
