Principal Investigator

Tamara Lotan, MD

Thanks for taking an interest in our research program!  I am a urologic pathologist with an active translational and basic science research program.  We have diverse interests in our group, ranging from basic studies of mTORC1 signaling in epithelial development and tumorigenesis to translational work aimed at developing predictive molecular biomarkers for prostate cancer.  In addition to this work, I examine and diagnose genitourinary tumors from biopsy and resection specimens at the Johns Hopkins Hospital.  I obtained my M.D. from the University of Chicago in 2003 and completed a residency in Anatomic Pathology there in 2007.  I came to Johns Hopkins to complete a fellowship in Urologic Pathology, and joined the faculty in 2008 where I currently am appointed as a Professor in the Departments of Pathology and Oncology.  When I’m not working, I spend most of my free time with my (very active!) five children and radiologist husband and also enjoy running and cooking.

Team Members

Kaushal Asrani, MBBS, PhD

Kaushal is a Research Associate in the Department of Pathology, at the Johns Hopkins University School of Medicine. He completed his undergraduate studies in medicine and obtained his MBBS at BJ Medical College at the University of Pune, India. He went on to earn his PhD in Cancer Biology at the University of Maryland, Baltimore where he studied the role of the Fn14 receptor as an invasive biomarker in HER2+ breast cancers, NSCLC and melanomas. He subsequently joined the Lotan lab as a postdoctoral fellow. He is broadly interested in the role of oncogenic receptor kinases and the PI3K/AKT-mTOR signaling axis in normal epithelial development and tumorigenesis in the epidermis, prostate and kidney. He received the JHU School of Medicine Young Investigator Award in 2018.

Juhyung Woo, PhD

Juhyung earned his PhD from Kyungpook University, Taegu South Korea in 2001.He joined as a Post-Doc. Fellow under the guidance of Dr. Edward Gabrielson at Johns Hopkins School of Medicine. Currently, he is  a Sr. Research Specialist in our lab, conducting a combination of basic and translational research. When not working, he spends his time playing basketball with his son.

Daniella Salles Corella, MD

Dr. Daniela Correia Salles is originally from Brazil, and she earned her medical degree from Petrópolis Medical School. After completing her internal medicine residency at the Santo Antônio Hospital-Obras Sociais Irmã Dulce, she pursued another residency in pathology at the University of São Paulo, where she was interested by the medical specialty of genitourinary pathology. Then in 2018, Dr. Salles performed a postdoctoral uropathology research fellowship at the Johns Hopkins Hospital under the supervision of Dr. Epstein. With an increasing interest in research, she joined the Lotan Lab to continue learning.

Thiago Vidotto, PhD

Thiago earned his BS in Biology from the University of Londrina, Brazil and Ph.D. in Genetics from the University of São Paulo, Brazil. During his Ph.D., he spent eight months as a research assistant at Queen’s University, Canada, where he investigated the effects of tumor-intrinsic genomic alterations in immunotherapy response of bladder, ovarian, and prostate tumors. Currently, he is a postdoc fellow at Johns Hopkins, investigating the methylome of African-American and European-American prostate cancer patients. He is also interested in understanding the roles of chromosomal aberrations in the anti-tumor immune response.

Sanjana Murali, MHS

Sanjana obtained her undergraduate in Biotechnology from India and came to the United States to pursue a master’s degree in Biochemistry and Molecular Biology from School of Public Health at Johns Hopkins. After graduation, she joined the Lotan lab as a research technologist, studying the various transcription factors and effectors of ROCK mediating desmosomal gene regulation in  mTORC1 loss of function keratinocytes. She spends her weekends with friends exploring charm city and its various café’s and restaurants!
