Lab members

Lorena received her PhD in Biomedicine from the Institute for Research in Biomedicine, Barcelona, Spain in 2009. As an EMBO postdoctoral fellow at UC Irvine, USA, she described new epigenetic mechanisms regulating transcriptional oscillations driven by the circadian clock, uncovering a role for 3D chromatin organization. Since 2016, she is an Associate Researcher at the IIBo-UNAM

Lorena Aguilar Arnal, PhD

Principal investigator

Marcia Bustamante Zepeda, MSc

Lab technician

Marcia received her B.S. in Biology from UNAM,  and her MS in Genetics and Molecular Biology from CINVESTAV-IPN. Marcia manages administrative tasks and constantly helps other lab members with daily experimental  routines. She is a heavy runner, and a very cheerful and welcoming personality.

Lucía received her PhD in Cell and Systems Biology from University of Toronto, Canada, in 2017, describing new roles for miRNAs in the control of seasonal behavior. She joined our lab as a postdoctoral researcher in 2018 to investigate how molecular clocks in the brain dictate metabolic adaptations to feeding. In 2019, she was a recipient of the L´Oréal-UNESCO-AMC for Women in Science award.

Lucía Mendoza Viveros, PhD


Quetzal graduated in Biology at UNAM, and received his MS degree in Biochemistry in 2015. In 2016, he joined the lab as a PhD student to uncover new roles for energy metabolism in synchronization of the mammalian molecular clock.  He is a recipient of a CONACyT fellowship. He is an enthusiast of the theater and performing arts.

Quetzalcoatl Escalante Covarrubias, MS

PhD Student

Nacho graduated in Pharmaceutical and Biological Chemistry at UNAM, and received his MS degree in Biochemistry in 2016. He joined the lab in 2017 to study transitions in chromatin 3D architecture and long range interaction´s dynamics during the circadian cycle.  He is a recipient of a CONACyT fellowship. He enjoys hiking and outdoor sports in general.

Ignacio Pacheco Bernal, MS

PhD Student

Edgar graduated in Biomedical Sciences at the University of Puebla (BUAP), and received his MS degree in Biochemistry from UNAM in 2017. He started his PhD in the lab in 2018, to decipher connections between metabolic signaling and epigenetic reprogramming during human stem cell differentiation.  He is a recipient of a CONACyT fellowship. He loves soccer, music concerts and trying new foods.

Edgar Sánchez Ramírez, MS

PhD Student

Mirna graduated in Biology at UNAM in 2019. She joined the lab in 2020 as a PhD student. Her research is focused on describing the role of histone methyltransferases in circadian gene expression using a combination of genome wide analyses and transgenic mice.  She is a recipient of a CONACyT fellowship.
