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

"Droplet sequencing reveals virulence gene clusters in extracellular vesicles from human microbiota"
Sotaro Takano
Newman Lab
Bacterial extracellular vesicles (BEVs), produced by a broad spectrum of bacteria, emerged as crucial delivery vehicles for genetic contents in microbiota. A vital determinant of their gene transfer efficiency is the gene content diversity within BEVs, an aspect that conventional metagenomics fails to capture. We currently bridged this gap with a novel droplet-based sequencing technique and comprehensively detailed DNA content within hundreds of individual BEVs. Our results revealed a significant fraction of BEVs carries specific functional gene sets that can bring genetic innovations in microbiota via HGT, unveiling critical insights into the potential functions of vesicular DNA in microbial communities.
"Unveiling the microcosm: archaea in extreme environments"
Aidyl Gonzalez-Serricchio
Sternberg Lab
I explore Archaea in extreme environments, focusing on lava tube ecosystems on Terceira Island, a volcanic island in the Azores archipelago of Portugal. I will present research conducted in the Gruta do Natal cave system. Through microbiome analysis, I discovered the dominance of Archaea and investigated their potential interactions in harsh conditions. I unveiled the absence of eukaryotes and the likely absence of moss microbiota. I'm gaining insights into the genetic makeup of possibly novel Archaea species, advancing our understanding of microbial diversity and survival strategies in extreme habitats.
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
