Gerard is interested in multimodal image registration and integration, single-cell MSI, bioinformatics, cheminformatics, statistical methods for hypothesis testing, automatic molecular annotation, and machine learning.

Gerard is a postdoctoral fellow who joined the Agar Lab in October 2021. He develops computational methods for targeted and untargeted metabolomics in MSI. One of his main focuses is the registration and integration of complementary imaging modalities such as MSI, MRI, multiplexed tissue immunofluorescence, and immunohistochemistry. Additionally, he devises computational approaches to enable and analyze single-cell MSI studies. He also develops machine-learning cheminformatic models to understand the link between the molecular structure of metabolites or drugs and complex properties such as MALDI ionization or blood-brain barrier permeability. Ultimately, his computational tools are aimed at better understanding brain tumors and their heterogeneity.

  • BSc in Chemistry and Biology from the University of Nantes, France (2014)

Affiliated to the laboratory of Prof. Oliver Pourquié, PhD (Department of Pathology), Clément is interested in the development of the vertebrate musculo-skeletal axis. Using chicken and mouse embryos as well as human embryonic or reprogrammed stem cells that recapitulate early development processes, he is deciphering the metabolism of the paraxial mesoderm using mass-spectrometry imaging and liquid-chromatography coupled with mass-spectrometry. He is in addition pursuing his interest in understanding cancer metabolism in DIPG, a devastating type of pediatric brain cancer.

Clément is currently a postdoctoral fellow who co-joined the laboratories of Prof. Pourquié and Prof. Agar in June 2021 after obtaining a PhD focusing on the interplay between cell signaling and metabolism in cancer, under the supervision of Dr. Raul V. Duran first at the European Institute of Chemistry and Biology Bordeaux, France and then at the Andalusian Molecular Biology and Regenerative Medicine Centre, Seville, Spain. He is now interested in understanding the similarities between cancer metabolism and early embryos and whether this knowledge of early embryo metabolism can help us to understand metabolic regulation in cancer cells.

Jennifer Gantchev, PhD

She is enthusiastically interested in investigating the relationship between genomic instability (DNA damage) and metabolism in glioblastomas.

Jenn is a postdoctoral fellow from Canada who joined the Agar lab in September 2022. She has a profound interest in the unknown and is one to ask questions about the world around her. She is often indulging in information about behavior, parenting, ecology, cancer, signaling pathways…. When she is not working on her research, she likes coaching her two children in soccer and hockey, she enjoys cycling, interacting with animals, and going on family outings.

Elisa York, PhD

Postdoctoral Research Fellow, Department of Neurobiology,  Harvard Medical School

Bio

  • PhD in Neuroscience from the University of British Columbia, Vancouver, Canada (2019)
  • BSc in Physiology and Psychology from the University of Western Ontario, London, Canada (2012)

Elisa is interested in how the brain regulates its dynamic energy demands, and specifically how cellular metabolism can change the function of neurons and glia.

Elisa is a postdoctoral fellow, co-supervised between Dr. Agar and Dr. Yellen. In this collaborative role, she performs physiological experiments on metabolically-active acute brain slices, including stable isotope tracing of glucose and other carbon sources. She has established a novel thermal preservation technique to rapidly fix the metabolic activity, and can now analyze the metabolic profile of this tissue by MALDI-MSI. Using this method, she is investigating which fuels are metabolized by neurons at rest and to support the energetic demands of activation. She is also exploring the neurometabolic differences across weaning, when mice switch from a milk diet to carbohydrate-rich solid foods.
