Tow Foundation Current Fellows

Post-Doctoral Fellows

Kelly Henry

Kelly Henry obtained her PhD in chemistry at Syracuse University in 2015. Her doctoral work focused on the structure-activity relationships and appetite-regulating effects of neuropeptides, using vitamin B12 as a drug delivery vehicle. In July 2015, she joined the lab of Jason Lewis at Memorial Sloan Kettering. She is currently working on interrogating oncogenic pathways and assessing target engagement using protein-based radiotracers via molecular imaging in cancer.


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. 

Roozbeh Eskandari

Roozbeh Eskandari received his PhD degree from Case Western Reserve University where he developed new intermediates for synthesis of oxidized lipids and explored their interactions with nuclear receptors. In Aug 2015, he joined the lab of Kayvan Keshari at Memorial Sloan Kettering Cancer Center. He is currently developing stable isotope labeled molecules for hyperpolarized magnetic resonance. His main focus is in vivo measurement of nutrient flux in Pancreatic Ductal Adenocarcinoma (PDAC) models.

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.


Patricia Manuela Ribeiro Pereira

Patricia Pereira obtained her PhD in medicinal chemistry from the University of Aveiro, Portugal, in October 2016. During her doctoral thesis she developed new photosensitizers by conjugating them with specific galactose motifs and validated them in the treatment of bladder cancer by photodynamic therapy. In November 2016, she joined the laboratory of Jason Lewis at Memorial Sloan Kettering. In her current role, she aims to modulate endocytic trafficking systems for improved immunoPET and radioimmunotherapy of bladder and gastric tumors. In addition to Dr. Lewis, Jeremy Durack and Yelena Janjigian have been kind to serve as a co-mentors in her research project and will be instrumental to the potential translation of the project in a clinical setting.


Sai Kiran Sharma

Sai Kiran Sharma obtained his PhD in pharmaceutical sciences from the University of Alberta, Canada, in 2014. His doctoral thesis work focused on the development and testing of immunoPET probes for the molecular imaging of epithelial ovarian cancer. In September 2014, he joined the laboratories of Jason Lewis at Memorial Sloan Kettering and Brian Zeglis at Hunter College of the City University of New York. In working between the two labs, he aims to develop antibody-based theranostic agents for the molecular imaging and therapy of ovarian cancer. 

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.

Stephen Jannetti

Stephen Jannetti earned his bachelor of science in biochemistry with a minor in computational sciences from Siena College in New York State in 2013. That same year he was accepted into the PhD in biochemistry program at the City University of New York Graduate Center. During his first year of the program he joined the Integrative Graduate Education and Research Traineeship radiochemistry program at Hunter College. The focus of his work is developing clinically relevant radiotherapies for glioblastoma. He conducts his research under Brian Zeglis at Hunter College and Thomas Reiner at Memorial Sloan Kettering.

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. 

Jiye Son

Jiye is a PhD student at Brooklyn College working in the lab of Daniel Heller at Memorial Sloan Kettering. Her research focuses on the synthesis of medicinal organometallic compounds and the delivery of those drugs using enzyme-responsive short peptides for anticancer therapeutics. Prior to starting graduate school, she received her bachelor’s degree in chemistry from SUNY Stony Brook University and was an employee of the Product Safety and Toxicology Department of the Estee Lauder Companies.
