Post-Doctoral Fellows

Elizabeth Coffee

Elizabeth Coffee obtained her MD at Texas A&M University, and completed her residency training in Neurology at the University of Alabama at Birmingham. During her residency training she helped validate new segmentation software for the volumetric analysis of primary and secondary central nervous system malignancies. She is currently completing training in Neuro-Oncology Fellowship at Memorial Sloan Kettering Cancer Center where she serves as chief fellow. She joined the laboratory of Dr. Kayvan Keshari in July 2021. In her current role, she aims to validate [1-13 C] dehydroascorbate as a novel probe in hyperpolarized MRI in order to examine the role of reactive oxygen species in the radioresistance of primary brain tumors. Dr. Ingo Mellinghoff serves as co-mentor for her research providing support in brain tumor animal models and guiding the project towards clinical translation.

Tyler El Rayes

Tyler El Rayes received his PhD from Weill Cornell Graduate School of Medical Sciences in 2015. His doctoral research in the lab of Vivek Mittal focused on characterizing the pre-metastatic microenvironment in lungs, and delineating a pathway linking lung inflammation to metastasis enhancement. He joined the lab of Morgan Huse at Memorial Sloan Kettering in 2016, where he is currently using intravital imaging, flow cytometry, and scRNA-seq to track early-stage melanoma clonal evolution and interactions with the immune system.

King Lam Hui

King Lam Hui received his PhD degree in physics from the University of Maryland, College Park, in 2015. His doctoral research work focused on the mechanobiology of T cell activation. Upon completion of his PhD, he joined the laboratory of Philipp Niethammer at Memorial Sloan Kettering as a research scholar. He is currently investigating the connection between inflammation and oxidative stress, using zebrafish as a model system and novel genetically-encoded redox / GPCR sensors to visualize signaling events in vivo.

Brian Madajewski

Brian Madajewski received his PhD in cancer cell biology from West Virginia University in 2016. His doctoral research work focused on the role of oxidative stress regulators in the promotion of non-small cell lung cancer and the maintenance of cancer stem cells. Following completion of his doctoral work, he joined the lab of Michelle Bradbury at Memorial Sloan Kettering as a postdoctoral research fellow. His current work focuses on the translational research of FDA-approved C dots in cancer theranostics.

Clayton Schwarz

Clayton Schwarz received his PhD from Stanford University in 2017. His doctoral work in the lab of Jan Skotheim focused on characterizing the feedback loop of Cdk2-cyclin E activity, Rb phosphorylation, and E2F-dependent transcription that regulates the mammalian G1/S transition. In 2019 he joined the laboratories of Anna-Katerina Hadjantonakis of Memorial Sloan Kettering and Eric Siggia of Rockefeller University. He is using a comparative imaging-based approach to investigate cell fate acquisition and tissue architecture in micropatterned gastruloids and mouse embryos.

Pre-Doctoral Fellows

Guillaume Dewaele Le Roi

Guillame Dewale Le Roi received his M.Sc. from Sorbonne University in Paris and moved to the United States to pursue his PhD within the Chemistry Graduate Program of the City University of New York (CUNY). He joined the laboratories of Brian Zeglis at Hunter College of CUNY and Jason Lewis at Memorial Sloan Kettering to pursue his passion for radiochemistry, molecular imaging, and translational science. His research focuses on the creation of novel strategies for the site-specific modification of proteins and peptides with radionuclides.

Michael Phipps

Michael Phipps graduated summa cum laude in 2017 from the University of Missouri in Columbia, Missouri, with a bachelor’s degree in chemistry. While at the University of Missouri, he fostered his interest in radiochemistry under Silvia Jurisson, researching radionuclide separations and chelator chemistry at the University of Missouri Research Reactor (MURR) and Harry S. Truman Memorial Veterans’ Hospital. In 2017, he accepted a graduate student position at Hunter College and the Graduate Center of the City University of New York. He now works in the labs of Lynn Francesconi at Hunter College and Jason Lewis at Memorial Sloan Kettering, pursuing a PhD in inorganic chemistry, researching novel PET imaging agents and therapeutic agents for the molecular imaging and therapy of cancers.
