Gayetri Ramachandran taught her first university class during the COVID-19 pandemic. While the online course was successful overall, it was a strange experience to teach without being able to see the students.

โIf youโre giving a seminar and you canโt see the other person, itโs extremely difficult,โ says Gayetri, a postdoctoral researcher at the Institut Necker Enfants Malades in Paris, France. โIf theyโre sleeping, I canโt see them. Itโs fine, you can sleep, but if I canโt see that youโre sleeping, then I canโt get that feedback in real time.โ
Earlier this summer, Gayetri had another opportunity to give an online presentation. Before the COVID-19 pandemic disrupted travel plans, she was scheduled to visit the Promega Headquarters in Madison, WI, to tour the facilities and meet with R&D scientists. Instead, Gayetri presented her research to a group of Promega scientists in the first Promega Virtual Customer Experience Visit.
Gayetri is the first recipient of the Prix National Jeunes Chercheurs, or National Young Researchers Prize, awarded by Promega France. This award recognizes researchers in university programs who are pursuing outstanding research, as nominated and voted on by their peers. The winner receives the opportunity to travel to the United States to attend the scientific conference of their choice and detour through Madison, WI, to meet with Promega scientists.
Unfortunately, the conference Gayetri planned to attend was cancelled, and her whole trip was subsequently called off as travel was restricted between the United States and Europe. However, thanks to video conferencing technology, Gayetri was still able to meet with a large group of Promega scientists to present her research and learn about emerging tools that could support her project.
โOur Customer Experience program is about making connections and giving people a behind-the-scenes look at Promega,โ says Tracy Worzella, Customer Experience Science Liaison. โFor younger scientists, itโs about celebrating their work and supporting in any way we can. When Gayetriโs trip was canceled, we offered the idea of a virtual visit because we knew there was so much value in making that connection, even if we couldnโt meet in person.โ

Gayetri presented her work with segmented filamentous bacteria (SFB) on a Microsoft Teams call with fifteen Promega scientists. These bacteria attach to the gut epithelia of mice and have been shown to induce several immune functions. Gayetriโs team believes that SFB could be engineered to express specific antigens, which could then be used to educate the immune system like a vaccine.
โIf weโre able to insert different antigens, it can be used as an immunostimulatory bacteria,โ Gayetri says. โIโm working with phages, as well as CRISPR-Cas9 and some plasmids. A lot of work has been done on the immunological side, but weโre missing information on the molecular biology of this bug.
Unlike common bacteria such as E. coli, there is no easy toolkit for working with SFB. For example, while E. coli can be grown quickly using established methods and recipes, SFB must be attached to epithelial cells. Gayetri also says that at this point, there arenโt many tools to modify the SFB genome. Fortunately, Gayetriโs visit also gave her the opportunity to speak directly with Promega R&D scientists to explore technologies that could help her overcome some of the challenges sheโs facing. Said Goueli, Sr. Research Fellow, gave a brief overview of the MTase-Glo™ Methyltransferase Assay, and Douglas Horejsh, Sr. Research Scientist, discussed new tools related to microbiome research.
โFor someone who is still discovering Promega, I felt that everyone was very welcoming and accepting,โ Gayetri says. โI got a great overview of whatโs happening at Promega and it helped me to know what else was available that I wasnโt aware of. If I need career help at some point, I could definitely ask Promega.โ
For the Promega team, this visit offered the chance to develop a relationship with a younger scientist doing exciting and innovative research.
โGiven these weird, unprecedented times, itโs great that we can still reach out and give scientists an experience of what Promega is all about,โ says Iain Ronald, Academic/Government Market Segment Director. โSheโs very promising, and she gave us a great idea of what she hopes to accomplish. Thatโs the most important part โ itโs not all about what youโve done, but where you plan to go next, and how you plan to get there. Weโre all here to promote the advancement of science.โ
