My research focus stems from a curiosity about how undifferentiated progenitor cells integrate intrinsic and extrinsic developmental signals to generate diverse neural cell types. I first cultivated this fascination with the mechanisms by which cells decide their fate at Memorial Sloan Kettering Cancer Center, where we published multiple studies investigating the specification and in vivo integration of pluripotent stem cell derivatives towards the development of cell replacement strategies for neurological disorders. Using this background as a springboard, my doctoral studies at Stanford University demonstrated a role for electrically-evoked calcium signals through a neuropsychiatric disease-relevant calcium channel on the differentiation of cortical neuron subtypes. Based on the broad implications of this work, I was selected to launch my independent research program as a Sandler Faculty Fellow at the University of California, San Francisco. As an independent investigator, I have established a research team that is integrating complementary approaches to interrogate roles of calcium signaling, electrical activity and ion channel splicing in sculpting brain development. We aim to expand on these efforts at Mount Sinai, where we moved in mid-2023, with the goal of developing a comprehensive understanding of intracellular signaling in mammalian brain development and elucidating how these fundamental mechanisms are deregulated in neurodevelopmental disorders and co-opted in adult neurological conditions. As a PI, I am committed to individualized mentorship and to fostering a supportive environment that values scientific rigor, learning, honesty, curiosity, hard work, collegiality, compassion, and inclusion.

When I am not in the lab, I enjoy long hikes with adorable dogs named Ellie, cooking, gardening, learning languages, and listening to podcasts.

    “There is no substitute for hard work.” -Thomas Edison

I graduated from UC Berkeley with a double major in Theater, Dance and Performance Studies and Molecular and Cell Biology. My early exposure to scientific research studying mechanisms underlying neurodegeneration in Dr. Steve Finkbeiner’s lab at UCSF and as a Master’s student in Dr. Leslie Weiner’s lab at USC shaped my interests in stem cell biology and disease modeling. It was during my PhD at UCSF in the Panagiotakos lab where I became absolutely fascinated by the regulation and function of intraorganellar calcium stores and how they influence the behaviors of the stem and progenitor cells of the developing cortex. Now as a postdoc, I am excited to continue investigating how calcium signaling mechanisms and ion channel diversity influence cortical development. When I’m not at the bench, I enjoy playing the piano and attending the theater.

Research associate, technician extraordinaire, and resident comedian of the Panagiotakos Lab! I’m keenly interested in understanding the developing brain and how dysfunctional calcium signaling pathways contribute to autism spectrum disorders (ASD) and intellectual disability. My research makes use of mouse models to study members of the Calcineurin/NFATc pathway in developing astrocytes, mature neurons, and progenitors of the developing cortex. Outside of lab, I enjoy playing soccer (big Barcelona fan!), video games, and exploring NYC!

I graduated from Queens College CUNY with a major in Neuroscience and Biology. During my time there, I conducted research in the Tajerian lab, where I studied the effects of chronic pain on mouse behavior as well as the microvasculature of the hippocampus. My fascination with the human brain deepened when I participated in the BRAINterns webinar series through Lenox Hill Hospital. When I’m not in the lab, you can often find me in a Regal movie theater, capturing the beauty of nature through photography, or volunteering as an EMT at my local fire department.

Hi! I am a proud Latina Long Islander studying Biology–Concentration in Neuroscience at Stony Brook University. My interest in neuro sparked early on when I entered a program throughout middle-high school and especially took off in my first neuro class in college. I unexpectedly came across Panagiotakos Lab one Tuesday night and now Tuesdays are my favorite. I love reading comics and watching dramas. When I’m not studying or working, you can find me reading at the beach or supervising a preschooler.

I was born in Albania but grew up in Italy. I moved from New Jersey to New York to complete a dual degree, a Bachelor’s and Master’s in Biological Science at Hunter College. In the lab of Dr. Melendez at Hunter, I worked on oligodendrocyte precursor cells’ differentiation in a mouse model and my thesis project led me to other fascinating glial cells (astrocytes and microglia). I am keen on understanding their developmental mechanisms and how these relate to neurological disease! Outside the lab, I enjoy training for a marathon, exploring NYC, baking, or simply vegetating on the couch.

I graduated from UW-Madison in Biochemistry. I was an undergrad researcher in Dr. William Hickey’s lab working on phosphorus solubilizing bacteria which can be used as biofertilizer. Following this, I pursued and obtained my Master’s degree in Biomedical Engineering. Shortly after graduation, I joined Dr. Yvette Yien’s lab as a technician and worked on the impact of iron deficiency during early developmental stages on red blood cell development, utilizing zebrafish as a model organism. My first exposure to brain development and calcium channel was during DRS-bytes event where Dr. Panagiotakos gave a compelling 5-min presentation on the regulation of calcium isoforms and their contribution to brain development. Her talk ignited my fascination with this field. My interest in brain development has been growing since I started my rotation in the lab.

I was made in China but exported to America to study in middle school. Then I moved from Indiana to California, where I attended UC Berkeley for undergraduate studies with the focus of molecular and cell biology – neurobiology. At Berkeley, I pursued my interest in Neuroscience with Dr. Ehud Isacoff by investigating the significance of experience in brain circuitry and behavior in zebrafish larval prey capture. I also studied neuroanatomy and neurodevelopment of pediatric epilepsy using zebrafish models with Dr. Scott Baraban. Prior to joining the OCS PhD program, I worked in the Schneider Lab at UCSF, studying the molecular and cellular processes that give rise to mandibular size and shape. I have a keen interest in the mechanisms that govern craniofacial development and its intricate connections with brain development with the goal of finding potential clinical treatments for congenital defects. Outside of school and work, I enjoy a good pot of tea with friends, speed-dialing Kanye, and brushing my teeth.
