I am/have been the co-supervisor of 9 postdoctoral researchers. I am currently the (co)supervisor of 6 Phd Students; with 2 that have already graduated. Also, I have been the (co-)supervisor of 12 MSc, and 9 honours students.

I have been awarded, together with my PhD student Rafael Salinas, two projects aiming at patenting a Synthetic Community (SynCom) that we are developing to improve crop production under xeric conditions:
- VIU26P0144 (ANID): EndoSym: formulado microbiológico para inoculación de semillas y mejora del fitness en maíz (2026-2027)
- LXXXVI Concurso Patentar para Transferir (Funding from the Pontificia Universidad Catolica de Chile): EndoSyn - SynCom de semillas mejorando la producción de cultivos alimentarios bajo sequía” (2026)

My lab, the Extreme Ecosystem Microbiomics & Ecogenomics lab, has an active Instagram account: @E2ME
