Congratulations to Carol De Groote Tavares for passing her Admission to Candidacy exam! Carol studies electrogenetics in Lactiplantibacillus plantarum and is a real credit to the program. Read about our group’s work on extracellular electron transfer in L. plantarum here.
Congratulations Alanna!
We’re happy to announce that Alanna Stull has passed her Masters thesis defense! Her research focused on controlling the structure and properties of engineered living materials. She modulated cell surface display through environmental factors and brought great insight into our materials. We’re excited to see what the next phase of her career brings!
Congratulations, Sara!
We’re excited to share that Dr. Sara Molinari will joining the Fishell Department of Bioengineering at the University of Maryland as an incoming professor this summer! Her lab will bridge synthetic biology and material science to develop multifunctional engineered living materials for health and environmental applications. Keep an eye out as she builds her new group!
Welcome Chloe and Robyn!
Ha Chau (Chloe) Nguyen and Robyn Alba have joined our group for their Ph.D. research. Chloe is in the Rice U.’s Systems, Synthetic, & Physical Biology Program and will be exploring the fundamental mechanisms of biomaterial formation. Robyn is in the Biochemistry & Cell Biology Program and will be creating living biosensors with bioelectronics. We’re so pleased to have them on the team!
Congratulations Joe!
Dr. Joe Tolar has successfully defended his PhD! His dissertation presentation covered “Expanding the Understanding of Extracellular Electron Transfer Mechanisms and the Physiological Impacts in Gram-Positive Bacteria” and you can read about his work here. He will be joining LevitasBio next.
Welcome Olivia!
Olivia Suggs has joined our group to work on allosteric protein switches as part of our Bioelectronics research. Olivia has a Bachelors in Biochemistry from Spelman College and is in the Biochemistry and Cell Biology Ph.D. program at Rice. We’re excited to have her on board!
Celebrating Esther!
We toasted to Esther and all the other NSF Graduate Research Fellowship Program recipients (with cake!) at Rice U. on Nov. 3. This fellowship is highly selective and we are very proud of Esther for her achievement. Support for a student like Esther is a big win for the field of engineered living materials!
New pub! Real-time bioelectronic sensing of environmental contaminants
Congratulations Lin, Josh, and Xu on their publication in Nature! This endeavor overcame challenges in biology and material science to create a specific, rapid bioelectronic sensor. With a detection time of minutes, this technology enables real-time monitoring of low concentration contaminants in water before they become irreversible, and is substantially faster and cheaper than fluorescence-based biosensors and liquid chromatography monitoring. To achieve this, the team engineered a synthetic electron transfer chain that pulls in proteins from four different organisms into E. coli, includes a post-translational gate to overcome rate limitations, and encapsulates the cells and electrode in conductive nanomaterials to improve signal to noise ratios. Proof of concept was demonstrated on thiosulfate and the endocrine disruptor 4-hydroxytamoxifen in environmental water samples, but the concept is applicable to a wide array of contaminants. Spanning the labs of Caroline Ajo-Franklin, Joff Silberg, and George Bennett, between Lawrence Berkeley National Lab and Rice University, this was truly a collaborative effort (our favorite kind)!
Check out the publication here, as well as Rice U’s write up of the project and the video below!
New post-doc position available!
We’re seeking a collaborative, curious post-doc to join our Biomaterials team. As we’re a very multidisciplinary group, the position is open to those with backgrounds in biochemistry, bioengineering, materials science, microbiology (C. crescentus experience a plus!), molecular biology, or related field. The main qualification is a strong interest in engineered living materials and their applications! Check out the flyer below for more information and contact us.
Dr. Caroline Ajo-Franklin featured at inauguration!
We’re proud to announce that Dr. Caroline Ajo-Franklin was one of just six individual faculty to be featured at the inauguration of the eighth Rice University president, Reginald DesRoches. She was selected to represent the Wiess School of Natural Sciences and the video below on the engineered living materials research of the Ajo-Franklin lab was shown during the ceremony!
