November 23rd, 2021 Webinar Speakers

Our next webinar will take place via the internet on Tuesday November 23rd at 8 PM EST/ 1 AM GMT. Sign up on our mailing list to receive the Zoom link!

We hope to see/hear from you all at one of our sessions or as one of the next speakers. If you are an early career scientist and would like to present your research, don't hesitate to submit an abstract today! For now, please learn more about our current speakers and their research below. We also thank the generous support from Cell Reports Physical Science, Merck, and the Royal Society of Chemistry.

Our featured speakers this week are José Esteban Andino-Enríquez (graduate student, Yachay Tech University, Ecuador), and Courtney Johnson (graduate student, Duke University, USA).


JOSE ESTEBAN ANDINO-ENRIQUEZ (on Twitter @joseesteban97)

Biography: José Esteban Andino Enríquez. Ecuadorian chemist from YachayTech University with experience in universities in Ecuador and the United States. Founder of the research group "Science for Kichwa." Throughout his career, he has carried out different socialization programs in schools and communities in Ecuador. They have allowed him to know the reality of education in the country. Leader and principal researcher of "Science for Kichwa" research group, whose main objective is to break barriers in the development and study of science in Kichwa by conserving indigenous peoples' intellect. Thus, promoting writing in Kichwa and contributing to improving the bilingual intercultural education system in Ecuador.

Title of Talk: Adaptation of the periodic table to Kichwa - an Ecuadorian native language and its diffusion process

Abstract: Minorities’ languages face transformation processes and struggle against many social and linguistic limitations. Education systems in these languages are not optimal to promote the teaching of ancestral knowledge and scientific research. This is the case of Kichwa, an Ecuadorian native language that more than half-million people speak with different variations among the country. Kichwa lacks science tools to respond to educational needs, unleashing the gradual loss of intercultural diversity. The adaptation of the periodic table to Kichwa was developed in this work, taking into account its different language variations and the Kichwa speaker’s opinion to ensure the acceptance of this scientific tool. This research aims to break barriers in the development and conservation of indigenous people’s intellect by promoting Kichwa deep-rooted writing and enhancing an excellent bilingual intercultural education system in Ecuador.

COURTNEY JOHNSON (on Twitter @Ceej64)

Biography: Courtney Johnson earned her B.S. in Chemistry from Texas Woman’s University and is currently a senior Chemistry Ph.D. Candidate at Duke University. As a founding member of the Welsher Lab, Courtney spearheaded development of 3D-FASTR, a new method for 3D Point-Scan Microscopy, and leads development of the multi-modal 3D-TrIm microscope for visualizing virus-cell interactions. Courtney is passionate about inspiring everyone around her to achieve excellence. She is an A+ Certified IT professional and an enthusiast of all things computing. Outside her research, she holds a blue belt in Brazilian Jiu-Jitsu.

Title of Talk: Multi-Scale 3D Visualization of the Cellular Landscape through Single-Virus Tracking

Abstract: Single-particle tracking methods have shifted the landscape of physical virology from bulk methods requiring ensemble averaging to the single virus level, yielding unparalleled quantitative information about viral infection dynamics. However, the disparate spatial scales between viruses and cells makes studying their interaction at high speed an impossible imaging task for any single microscope.

Here we present 3D Tracking and Imaging microscopy (3D-TrIm): a multi-modal solution that combines high-speed active feedback tracking with simultaneous rapid volumetric two-photon imaging. The 3D-TrIm microscope simultaneously acquires co-registered volumes featuring the 3D trajectories of fluorescent virus-like particles (VSV-G pseudotyped lentivirus) with large-scale two-photon volumetric images of the surrounding live-cell environment. This approach yields an unprecedented 3D view into the interaction of virions at the cellular interface. We tracked virus-like particles both inside and outside of the cell, from first contacts with the cell membrane to intracellular trafficking at high spatiotemporal precision.
