My research integrates various fields, including genetics, molecular biology, imaging, post-imaging processing, computational biology, and behavioral approaches. Recently, I have also ventured into single cell and spatial transcriptomics. Using Drosophila melanogaster as my model organism, I aim to uncover novel biological concepts and developmental mechanisms.

Throughout the past decade, my expertise has focused on the development of three key components of the locomotor system: muscles, glia, and motoneurons. Within larval muscles, I have made significant discoveries regarding the transcriptional machinery responsible for determining their morphological identity (Enriquez et al., 2010, 2012, and 2015). Additionally, I pioneered the revelation that motoneurons exhibit a unique transcription factor code at the single cell level, which governs the morphology of their dendritic arbor and axonal targeting (Enriquez et al., 2015). To achieve this breakthrough, I developed the innovative MARCMbow technique, enabling the visualization of motoneurons at the single cell level while simultaneously modifying their genome.

As a group leader, I expanded my research to include the study of glial cells within the locomotor system. By introducing the cisMARCM technique (Enriquez et al., 2018), I demonstrated that glial cell development is not predetermined but rather exhibits plasticity and stochasticity. Although this work is sometimes viewed as a postdoc publication, I carried it out at Columbia University, where I was promoted to Associate Research Scientist and secured my first PI grant from the American ALS Association. With this funding, I initiated investigations into glial cells, which I continued at the IGFL with the support of my new research group.

My contributions as a co-corresponding author on a publication have gained recognition, particularly through its highlight in the 2018 F1000Prime Recommendation. Furthermore, recent studies have confirmed the conservation of glial cell development logic throughout evolution (Solène Clavreul et al., 2019).

In more recent endeavors, I utilized genetic manipulations and an innovative computational tool to reveal that transcription factor codes governing motoneuron morphologies are progressively established in immature motoneurons based on their birth order. Furthermore, we made a significant discovery indicating that RNA binding proteins post-transcriptionally regulate the establishment of these transcription factor codes in immature motoneurons, ultimately influencing the establishment of the axon muscle-connectome and the production of a precise number of MNs (Guan et al., 2022, 2023).
