Prior to joining the Jain Lab her work focused on exploring new radiotherapeutics for cancer. Also, she worked as a visiting lecturer for both undergraduate and post-graduate students in different Egyptian Universities. By joining the amazing group at the Jain Lab, she is investigating with the team the development of new imaging agents as diagnostic tools for infectious diseases as well as developing new regimens for the treatment of MDR forms of TB.
Medha Singh, Ph.D
Medha is a Research Fellow at Johns Hopkins University, investigating the immuno-pathophysiology of pulmonary and CNS tuberculosis. She assesses novel host-directed therapeutics and explores innovative radiotracers for bacterial and fungal infection imaging. Holding a Ph.D. from the University of Delhi, India, she balances her scientific pursuits with culinary delights, offbeat travel, leisurely walks, and Netflix binges.
Yuderleys Masias-Leon, M.D
Yuderleys is an M.D from Colombia, she received her medical degree from the Industrial University of Santander. Currently, she is working on the development of new PET tracers for infectious diseases, especially fungal and bacterial ones. She loves her pets, Loki and Greta. She enjoys traveling and exploring new places, spending time with her friends, and savoring good food. Reading, coloring, and swimming are her favorite hobbies.
Carlos Ruiz-Gonzalez, M.D
Carlos is a Research Fellow at Johns Hopkins University. He obtained his MD degree from the Industrial University of Santander in Colombia. He is interested on infectious diseases.
