Events
CEMINAR
The most important community-oriented activity we sponsor is CEMINAR, formerly MicroMorning, a monthly seminar series where students and postdocs in the CEMI program present their work. Usually 2 individuals present 20-25 min talks (+ 5 min questions) to fill the hour, but on rare occasions we invite an outside speaker. CEMINAR is primarily designed to provide CEMI students and postdocs with an opportunity to practice giving a formal talk to a friendly Caltech audience. Numerous collaborations have been sparked between labs at Caltech thanks to creative connections made during these seminars. View past CEMINARS

"Spatiotemporal regulation of programmed cell death in Pseudomonas aeruginosa biofilms"
Georgia Squyres
Newman Lab
Bacteria often live in dense communities called biofilms. These bacteria must collectively organize their behavior, with subpopulations of cells carrying out distinct roles during biofilm development, but how and why these behaviors are patterned has remained unclear. Using single-cell biofilm imaging, we find that programmed cell death occurs at a specific position in the biofilm, and that this mode of regulation allows the biofilm to make a uniform matrix. We introduce a model in which cells in P. aeruginosa biofilms integrate environmental gradients with self-produced signals to determine their position in the biofilm and pattern their behavior.
"Genetically encoded reporters for multiplexed imaging of microbes on ultrasound"
Nivin Nyström
Shapiro Lab
Ultrasound provides high spatial resolution data of deep tissues at relatively low cost. Air-filled protein nanostructures called gas vesicles (GVs) operate as genetically-encoded reporters for in vivo ultrasound imaging of engineered cells, thereby enabling measurements of specific molecular events through acoustic readouts. Our objective is to engineer acoustic reporter genes for multiplexed imaging of cells on ultrasound. We employ high-throughput in cellulo engineering methods to this end, and identify mutants with increased acoustic responses for more sensitive imaging and with distinct acoustic responses for multiplexing.
Social Events
In addition to CEMINAR, CEMI sponsors social events during the academic year:
Fall Poster Sessions: All CEMI labs present one or more posters on their lab’s research. This helps incoming/current students and postdocs remain up-to-date on that latest research projects going on across the campus. One attractive feature of Caltech is that students admitted in any graduate program are welcome to rotate in any lab (as long as the lab is taking students), so this poster session can open up new interests and areas for exploration. It also can spawn new collaborations between labs.
Spring Lectures and Evening Gala: To celebrate the start of the calendar year, we invite a keynote speaker from outside Caltech to give a seminar, plus a few shorter talks by assistant professors or postdocs at Caltech and other local universities. These “Spring Lectures” are open to anyone interested. As a companion event, we hold a formal gathering for a limited number of CEMI sponsors, faculty, and students and postdocs currently being supported by CEMI grants. The evening’s entertainment is organized by a different CEMI lab each year, and the evening culminates with a presentation of the “CEMI Oscars” (we are close to Hollywood, after all…), roasting CEMI members for notable achievements in the past year, all in good fun.

Spring Happy Hour: In recognition of the fact that sometimes the most inspired ideas come when we least expect them, we promote casual conversation between all members of the CEMI community supplemented with drinks and food at the start of the spring term (no posters required!).
CEMI Spring Celebration of Science: This hour-long science program featured short lightning talks from CEMI graduate students and postdocs followed by time to talk with the speakers and socialize with our CEMI colleagues. The inaugural event was held on May 12, 2021.
Workshops
CEMI occasionally supports training courses at Caltech that provide members of the CEMI community with an opportunity for intensive training in a particular area. Any member of the CEMI community is welcome to suggest a topic for a workshop. Please contact the CEMI administrator if you have an idea. View past workshops
