I am Agronomic Engineer (2006; UPV, Valencia). In 2007, I was awarded an INIA fellowship to carry out a PhD thesis in Biotechnology under the supervision of Dr. Francisco Tadeo and Dr. Manuel Talón at IVIA (2007-2011). I conducted my postdoctoral research (2012-2016) in the group of Dr. Marcus Heisler at EMBL (Germany). I have led a project as a Career Track Fellow (2018-2021) at IBMCP (CSIC-UPV, Valencia) thanks to the ComFuturo program (FGCSIC), and hosted by Dr. Cristina Ferrándiz, with whom I have been collaborating the last years. This project also got the seal of excellence of H2020-MSCA-IF-2017. Recently, I have been awarded a Ramón y Cajal fellowship (2022) and I am leading my independent research line at IBMCP (January 2023).

During my research career, I have developed research lines in the fields of Plant Development, Biotechnology, Genetics and Molecular and Cell Biology. My past research lines include: i) studying the molecular basis of citrus abscission through genomic approaches, ii) understanding the gene regulatory networks controlling meristem function and organ development in Arabidopsis thaliana, and iii) characterization of the genetic pathways and signals that regulate proliferative arrest in monocarpic plants.

My current research line is focused on how different hormones and genetic networks regulate the balance between stem cell proliferation and differentiation in the shoot apical meristem, which is crucial for building the plant architecture, and ensuring shoot growth and flower/fruit production.

  2. Characterization of the global proliferative arrest and its potential as a breeding target in cereals (Late-GPA-Plants; ComFuturo). Paz Merelo (PI). IBMCP. 2018-2021.
  3. European Research Council (GA 261081). Marcus Heisler (PI), Paz Merelo (Postdoctoral researcher). EMBL. 2010-2015.
  4. Isolation and molecular characterization of genes related to citrus production and fruit quality (RTA2008-00065-00-00). Francisco Tadeo Serrano (PI), Paz Merelo (Team member; PhD). IVIA. 2008-2010.
